ChatGPT + Enterprise data (Java)
A Java sample app that chats with your data using OpenAI and AI Search.

ChatGPT + Enterprise data with Azure OpenAI and Azure AI Search - Java Version

This repo is the Java version of the well known ChatGPT + Enterprise data code sample originally written in python.

It demonstrates best practices for creating ChatGPT-like experiences over your own data using the Retrieval Augmented Generation pattern. It uses Azure OpenAI Service to access the ChatGPT model gpt-35-turbo, and Azure Azure AI Search for data indexing and retrieval.

This repository includes sample data so it's ready to try end to end. In this sample application we use a fictitious company called Contoso Electronics, and the experience allows its employees to ask questions about the benefits, internal policies, as well as job descriptions and roles.

    • Important: Ensure you can run pwsh.exe from a PowerShell command. If this fails, you likely need to upgrade PowerShell.

NOTE: Your Azure Account must have Microsoft.Authorization/roleAssignments/write permissions, such as User Access Administrator or Owner.

Starting from scratch

You can clone this repo and change directory to the root of the repo. Or you can run azd init -t Azure-Samples/azure-search-openai-demo-java.

Once you have the project available locally, run the following commands if you don't have any pre-existing Azure services and want to start from a fresh deployment.

  1. Run

    azd auth login
  2. Run

    azd up
    • This will provision Azure resources and deploy this sample to those resources, including building the search index based on the files found in the ./data folder.
    • For the target location, the regions that currently support the models used in this sample are East US, France Central, South Central US, UK South, and West Europe. For an up-to-date list of regions and models, check here
  3. After the application has been successfully deployed you will see a URL printed to the console. Click that URL to interact with the application in your browser.

It will look like the following:

'Output from running azd up'

NOTE: It may take a minute for the application to be fully deployed.

Deploying with existing Azure resources

If you already have existing Azure resources, you can re-use those by setting azd environment values.

Existing resource group

  1. Run azd env set AZURE_RESOURCE_GROUP {Name of existing resource group}
  2. Run azd env set AZURE_LOCATION {Location of existing resource group (i.e eastus2)}

Existing OpenAI resource

  1. Run azd env set AZURE_OPENAI_SERVICE {Name of existing OpenAI service}
  2. Run azd env set AZURE_OPENAI_RESOURCE_GROUP {Name of existing resource group that OpenAI service is provisioned to}
  3. Run azd env set AZURE_OPENAI_SERVICE_LOCATION {Location of existing resource (i.e eastus2)}. Only needed if your OpenAI resource is in a different location than the one you'll pick for the azd up step.
  4. Run azd env set AZURE_OPENAI_CHATGPT_DEPLOYMENT {Name of existing ChatGPT deployment}. Only needed if your ChatGPT deployment is not the default 'chat'.
  5. Run azd env set AZURE_OPENAI_EMB_DEPLOYMENT {Name of existing GPT embedding deployment}. Only needed if your embeddings deployment is not the default 'embedding'.

Existing Azure AI Search resource

  1. Run azd env set AZURE_SEARCH_SERVICE {Name of existing Azure AI Search service}
  2. Run azd env set AZURE_SEARCH_SERVICE_RESOURCE_GROUP {Name of existing resource group with ACS service}
  3. If that resource group is in a different location than the one you'll pick for the azd up step, then run azd env set AZURE_SEARCH_SERVICE_LOCATION {Location of existing service}
  4. If the search service's SKU is not standard, then run azd env set AZURE_SEARCH_SERVICE_SKU {Name of SKU}. The free tier won't work as it doesn't support managed identity. (See other possible values)

Other existing Azure resources

You can also use existing Form Recognizer and Storage Accounts. See ./infra/main.parameters.json for list of environment variables to pass to azd env set to configure those existing resources.

Provision remaining resources

Now you can run azd up, following the steps in Deploying from scratch above. That will both provision resources and deploy the code.

Redeploying

If you've only changed the backend/frontend code in the app folder, then you don't need to re-provision the Azure resources. You can just run:

azd deploy

If you've changed the infrastructure files (infra folder or azure.yaml), then you'll need to re-provision the Azure resources. You can do that by running:

azd up

Examples of an azd deployment changing the default chatgpt deployment model

azd auth login
azd env set AZURE_OPENAI_CHATGPT_MODEL "gpt-4" # Change the chatgpt model to gpt-4
azd up

NOTE: This sample has been tested with gpt-35-turbo/0613 model version.Using other models or different versions might result in unexpected behavior.

Examples of an azd deployment reusing an existing Azure OpenAI and Azure AI Search resources

azd auth login
azd init -t Azure-Samples/azure-search-openai-demo-java.

azd env set AZURE_RESOURCE_GROUP "openai-test-resource-group" # Target resource group for the new resources
azd env set AZURE_LOCATION "eastus" # Target region for the new resources

azd env set AZURE_OPENAI_SERVICE "my-openai-test-service" # Name of the OpenAI service
azd env set AZURE_OPENAI_RESOURCE_GROUP "my-openai-test-resource-group" # Resource group where the OpenAI service is deployed
azd env set AZURE_OPENAI_SERVICE_LOCATION "eastus2" # Region of the OpenAI service
azd env set AZURE_OPENAI_CHATGPT_DEPLOYMENT "gpt-35-turbo" # The "Deployment name" of the deployed model, deployed in the Azure OpenAI studio
azd env set AZURE_OPENAI_EMB_DEPLOYMENT "text-embedding-ada-002"  # The "Deployment name" of the deployed model, deployed in the Azure OpenAI studio

azd env set AZURE_SEARCH_SERVICE "my-acs-test-service" # Name of the ACS service
azd env set AZURE_SEARCH_SERVICE_RESOURCE_GROUP "my-acs-test-resource-group" # Resource group where the ACS service is deployed
azd env set AZURE_SEARCH_SERVICE_LOCATION "eastus2" # Region of the ACS service

azd up

Running locally

  1. Run

    az login
  2. Change dir to app

    cd app
  3. Run the ./start.ps1 (Windows) or ./start.sh (Linux/Mac) scripts or run the "VS Code Task: Start App" to start the project locally.

  4. Wait for the Spring Boot application to start and refresh your browser to http://localhost:8080

UI Navigation

  • In Azure: navigate to the Azure WebApp deployed by azd. The URL is printed out when azd completes (as "Endpoint"), or you can find it in the Azure portal.
  • Running locally: navigate to localhost:8080

Once in the web app:

  • Try different topics in chat or Q&A context. For chat, try follow-up questions, clarifications, ask to simplify or elaborate on answer, etc.
  • Explore citations and sources
  • Click on "settings" to try different options, tweak prompts, etc.

Enabling optional features

Enabling Application Insights

Applications Insights is enabled by default. It allows to investigate each request tracing along with the logging of errors.

If you want to disable it set the AZURE_USE_APPLICATION_INSIGHTS variable to false before running azd up

  1. Run azd env set AZURE_USE_APPLICATION_INSIGHTS false
  2. Run azd up

To see the performance data, go to the Application Insights resource in your resource group, click on the "Investigate -> Performance" blade and navigate to any HTTP request to see the timing data. To inspect the performance of chat requests, use the "Drill into Samples" button to see end-to-end traces of all the API calls made for any chat request. Under "Trace & Events" panel you can review custom Java informational logs to better understand content of OpenAI requests and responses.

Tracing screenshot

To see any exceptions and server errors, navigate to the "Investigate -> Failures" blade and use the filtering tools to locate a specific exception. You can see Java stack traces on the right-hand side.

Enabling authentication

By default, the deployed Azure web app will have no authentication or access restrictions enabled, meaning anyone with routable network access to the web app can chat with your indexed data. You can require authentication to your Microsoft Entra by following the Add app authentication tutorial and set it up against the deployed web app.

To then limit access to a specific set of users or groups, you can follow the steps from Restrict your Microsoft Entra app to a set of users by changing "Assignment Required?" option under the Enterprise Application, and then assigning users/groups access. Users not granted explicit access will receive the error message -AADSTS50105: Your administrator has configured the application <app_name> to block users unless they are specifically granted ('assigned') access to the application.-

RAG Implementation Options

This repo is focused to showcase different options to implement semantic search on private documents using RAG patterns with Java, Azure OpenAI and Semantic Kernel. Below you can find the list of available implementations.

Conversational Style RAG Approach Description Java Open AI SDK Java Semantic Kernel
One Shot Ask PlainJavaAskApproach Use Azure AI Search and Java OpenAI APIs. It first retrieves top documents from search and use them to build a prompt. Then, it uses OpenAI to generate an answer for the user question.Several search retrieval options are available: Text, Vector, Hybrid. When Hybrid and Vector are selected an additional call to OpenAI is required to generate embeddings vector for the question.
Chat PlainJavaChatApproach Use Azure AI Search and Java OpenAI APIs. It first calls OpenAI to generate a search keyword for the chat history and then answer to the last chat question.Several search retrieval options are available: Text, Vector, Hybrid. When Hybrid and Vector are selected an additional call to OpenAI is required to generate embeddings vector for the chat extracted keywords.
One Shot Ask JavaSemanticKernelWithMemoryApproach Use Java Semantic Kernel framework with built-in MemoryStore for embeddings similarity search. A semantic function RAG.AnswerQuestion is defined to build the prompt using Memory Store vector search results.A customized version of SK built-in CognitiveSearchMemoryStore is used to map index fields populated by the documents ingestion process.
One Shot Ask JavaSemanticKernelChainsApproach Use Java Semantic Kernel framework with semantic and native functions chaining. It uses an imperative style for AI orchestration through semantic kernel functions chaining. InformationFinder.SearchFromQuestion native function and RAG.AnswerQuestion semantic function are called sequentially. Several search retrieval options are available: Text, Vector, Hybrid.
One Shot Ask JavaSemanticKernelPlannerApproach Use Java Semantic Kernel framework with built-in Planner for functions orchestration. It uses a declarative style for AI orchestration through the built-in SequentialPlanner. SequentialPlanner call OpenAI to generate a plan for answering a question using available skills/plugins: InformationFinder and RAG. Several search retrieval options are available: Text, Vector, Hybrid. ⚠️ This approach is currently disabled within the UI, pending fixes for this feature.
Chat JavaSemanticKernelWithMemoryApproach Use Java Semantic Kernel framework with built-in MemoryStore for embeddings similarity search. A semantic function RAG.AnswerConversation is defined to build the prompt using Memory Store vector search results. A customized version of SK built-in CognitiveSearchMemoryStore is used to map index fields populated by the documents ingestion process.
Chat JavaSemanticKernelChainsApproach Use Java Semantic Kernel framework with semantic and native functions chaining. It uses an imperative style for AI orchestration through semantic kernel functions chaining. InformationFinder.SearchFromConversation native function and RAG.AnswerConversation semantic function are called sequentially. Several search retrieval options are available: Text, Vector, Hybrid.

The plain Java Open AI sdk based implementations are stable. Java Semantic Kernel based implementations are still experimental and it will be consolidated as soon as Java Semantic Kernel beta version will be released. Below a brief description of the SK integration status:

App Continuous Integration

GitHub

if you don't want to use azd to build and deploy the app, a GitHub automated CI pipeline is provided in .github/workflows/app-ci.yml. Some notes about the CI pipeline design:

  • It uses a "branch per environment approach". The deploy environment name is computed at 'runtime' based on a git branch. You can check branch/env-name mapping logic in the "set environment for branch" step (line 29). The current implemented logic maps everything to a dev like environment. Therefore, on each git push on the main branch the pipeline is triggered trying to deploy to an environment called Development. For more info about GitHub environments and how to set specific env variables and secrets read here.
  • GitHub's environment variables and secrets are used to configure development environment specific configuration. They need to be configured manually in GitHub repository settings:
    • AZUREAPPSERVICE_PUBLISHPROFILE is used to store the azure app service publish profile configuration securely.
    • AZUREAPPSERVICE_APP_NAME is used to store the azure web app resource name generated during infra arm deployment.

To properly configure automated build and deploy for both backend and frontend components follow below steps:

  1. Go to your forked repository in GitHub and create an environment called 'Development' (yes this is the exact name; don't change it). If you want to change the environment name (also adding new branches and environments, change the current branch/env mapping) you can do that, but make sure to change the pipeline code accordingly in .github/workflows/app-ci.yml (starting line 29)
  2. Create 'Development' environment secrets for the azure web app hosting both frontend and backend publish profiles. You'll need to copy and paste the xml content from the .PublishSettings file into the secret value:
    • Create a secret with name AZUREAPPSERVICE_PUBLISHPROFILE and set the Value field to publish profile of the azure web app
  3. Create 'Development' environment variables for azure web app resource name:
    • Create a variable with name AZUREAPPSERVICE_APP_NAME and set the Value field to the azure web app resource name
  4. For each commit you push check the status of the triggered pipeline in the GitHub Actions tab, you should see a pipeline has been triggered for the specific commit. If everything is ok you should see green checkmark on both build and deploy jobs in the pipeline detail like below:

pipeline success

Azure DevOps

Azure Devops can also be used to build and deploy the app. Azure Devops automated CICD pipeline is provided in .azdo/pipelines/app-ci.yaml. Some notes about the CI/CD pipeline design:

  • Similar to GitHub action above, this pipeline uses branch per environment approach as well.
  • Azure Devops library variable groups and variables are used to configure environment specific configuration. They need to be configured manually in Azure Devops Pipeline Library.
  1. Navigate to Pipeline / Library
  2. Add new variable group azureSearchOpenAiDemoJavaDev and variable azureAppServiceName. Put the name of the Azure App Service for development as the value.
  3. Add new variable group azureSearchOpenAiDemoJavaProd and variable azureAppServiceName. Put the name of the Azure App Service for production as the value.

Connect Azure Devops to the GitHub Repo:

  1. Create a new pipeline.
  2. For 'Where is your code?' Select GitHub.
  3. Go through the GitHub App authentication process GitHub App.
  4. Select Existing Azure Pipeline YAML file.
  5. Point dropdown values to the path .azdo/pipelines/app-ci.yaml.
  6. Do not Run but Save the pipeline. Once saved, you will see dev and prod environment got automatically created under Pipeline / Environments. You can set up Approvals and Checks within environments if necessary.

Connect Azure Devops to Azure:

  1. Add a Service Connection following this guide to allow Azure Devops pipeline to connect to your Azure resources /App Service.
  2. Modify .azdo/pipelines/app-ci.yaml '' and replace it with the name of the Service Connection. location1 location2

You can now either run the pipeline manually or commit to a branch to trigger the pipeline. azDoPipeline success

Custom Data Ingestion and Indexing

The repository includes sample pdf documents in the data folder. They are ingested in blob container and then indexed in Azure AI Search during infra provisioning by Azure Developer CLI post provision hooks (see line 23 in azure.yaml)

If you want to chat with your custom documents you can:

  1. Add your pdf documents in the data folder.
  2. Open a terminal and cd to repo root folder. Example cd path/to/your/custom/dir/azure-search-openai-demo-java
  3. Run ./scripts/prepdocs.ps1 if you are on windows or ./scripts/prepdocs.sh on linux
  4. Wait the script to complete. This is not a 'delta' process, it's not updating only the new files you've added. Instead, on each run, all documents in data folder will be ingested. Feel free to add new files you want to ingest and delete/move the old documents from the data folder. Once you've run the script and it completes successfully, Azure AI Search index has been updated and stored (until you want to manually delete it from your azure Azure AI Search instance)
  5. if ingestion and indexing is completed successfully you should see a message like this prepdocs success

Productionizing

This sample is designed to be a starting point for your own production application, but you should do a thorough review of the security and performance before deploying to production. Here are some things to consider:

  • OpenAI Capacity: The default TPM (tokens per minute) is set to 30K. That is equivalent to approximately 30 conversations per minute (assuming 1K per user message/response). You can increase the capacity by changing the chatGptDeploymentCapacity and embeddingDeploymentCapacity parameters in infra/main.bicep to your account's maximum capacity. You can also view the Quotas tab in Azure OpenAI studio to understand how much capacity you have.
  • Azure Storage: The default storage account uses the Standard_LRS SKU. To improve your resiliency, we recommend using Standard_ZRS for production deployments, which you can specify using the sku property under the storage module in infra/main.bicep.
  • Azure AI Search: The default search service uses the Standard SKU with the free semantic search option, which gives you 1000 free queries a month. Assuming your app will experience more than 1000 questions, you should either change semanticSearch to "standard" or disable semantic search entirely in the /app/backend/approaches files. If you see errors about search service capacity being exceeded, you may find it helpful to increase the number of replicas by changing replicaCount in infra/core/search/search-services.bicep or manually scaling it from the Azure Portal.
  • Azure App Service: The default app service plan uses the Basic SKU with 1 CPU core and 1.75 GB RAM. We recommend using a Premium level SKU, starting with 1 CPU core. You can use auto-scaling rules or scheduled scaling rules, and scale up the maximum/minimum based on load.
  • Authentication: By default, the deployed app is publicly accessible. We recommend restricting access to authenticated users. See Enabling authentication above for how to enable authentication.
  • Networking: We recommend deploying inside a Virtual Network. If the app is only for internal enterprise use, use a private DNS zone. Also consider using Azure API Management (APIM) for firewalls and other forms of protection. For more details, read Azure OpenAI Landing Zone reference architecture.
  • Loadtesting: We recommend running a loadtest for your expected number of users. You can use Azure Load Test with Apache Jmeter

Cost estimation

Pricing varies per region and usage, so it isn't possible to predict exact costs for your usage. However, you can try the Azure pricing calculator for the resources below.

  • Azure App Service: Basic Tier with 1 CPU core, 1.75 GB RAM. Pricing per hour. Pricing
  • Azure OpenAI: Standard tier, ChatGPT and Ada models. Pricing per 1K tokens used, and at least 1K tokens are used per question. Pricing
  • Form Recognizer: SO (Standard) tier using pre-built layout. Pricing per document page, sample documents have 261 pages total. Pricing
  • Azure AI Search: Standard tier, 1 replica, free level of semantic search. Pricing per hour.Pricing
  • Azure Blob Storage: Standard tier with ZRS (Zone-redundant storage). Pricing per storage and read operations. Pricing
  • Azure Monitor: Pay-as-you-go tier. Costs based on data ingested. Pricing

To reduce costs, you can switch to free SKUs for Azure App Service and Form Recognizer by changing the parameters file under the infra folder. There are some limits to consider; for example, the free Form Recognizer resource only analyzes the first 2 pages of each document. You can also reduce costs associated with the Form Recognizer by reducing the number of documents in the data folder, or by removing the postprovision hook in azure.yaml that runs the prepdocs.py script.

⚠️ To avoid unnecessary costs, remember to take down your app if it's no longer in use, either by deleting the resource group in the Portal or running azd down.

FAQ

Why do we need to break up the PDFs into chunks when Azure AI Search supports searching large documents?

Chunking allows us to limit the amount of information we send to OpenAI due to token limits. By breaking up the content, it allows us to easily find potential chunks of text that we can inject into OpenAI. The method of chunking we use leverages a sliding window of text such that sentences that end one chunk will start the next. This allows us to reduce the chance of losing the context of the text.

How can we upload additional PDFs without redeploying everything?

To upload more PDFs, put them in the data/ folder and run ./scripts/prepdocs.sh or ./scripts/prepdocs.ps1. To avoid reuploading existing docs, move them out of the data folder. You could also implement checks to see whats been uploaded before; our code doesn't yet have such checks.

How do you use GPT-4 with this sample?

In infra/main.bicep, change chatGptModelName to 'gpt-4' instead of 'gpt-35-turbo'. You may also need to adjust the capacity above that line depending on how much TPM your account is allowed.

What is the difference between the Chat and Ask tabs?

The chat tab uses the approach programmed in PlainJavaChatApproach.

  • It uses the ChatGPT API to turn the user question into a good search query.
  • It queries Azure AI Search for search results for that query (optionally using the vector embeddings for that query).
  • It then combines the search results and original user question, and asks ChatGPT API to answer the question based on the sources. It includes the last 4K of message history as well (or however many tokens are allowed by the deployed model).

The ask tab uses the approach programmed in PlainJavaChatApproach.

  • It queries Azure AI Search for search results for the user question (optionally using the vector embeddings for that question).
  • It then combines the search results and user question, and asks ChatGPT API to answer the question based on the sources.

There are also three other /ask approaches which are implemented using Java Semantic Kernel sdk. Development it's still experimental and it will be consolidated as soon as semantic kernel beta version will be released. Below a brief description of the SK integration status:

What does the `azd up` command do?

The azd up command comes from the Azure Developer CLI, and takes care of both provisioning the Azure resources and deploying code to the selected Azure hosts.

The azd up command uses the azure.yaml file combined with the infrastructure-as-code .bicep files in the infra/ folder. The azure.yaml file for this project declares several "hooks" for the prepackage step and postprovision steps. The up command first runs the prepackage hook which installs Node dependencies and builds the React.JS-based JavaScript files. It then packages all the code (both frontend and backend) into a zip file which it will deploy later.

Next, it provisions the resources based on main.bicep and main.parameters.json. At that point, since there is no default value for the OpenAI resource location, it asks you to pick a location from a short list of available regions. Then it will send requests to Azure to provision all the required resources. With everything provisioned, it runs the postprovision hook to process the local data and add it to an Azure AI Search index.

Finally, it looks at azure.yaml to determine the Azure host (appservice, in this case) and uploads the zip to Azure App Service. The azd up command is now complete, but it may take another 5-10 minutes for the App Service app to be fully available and working, especially for the initial deploy.

Related commands are azd provision for just provisioning (if infra files change) and azd deploy for just deploying updated app code.

How can we view logs from the App Service app?

You can view production logs in the Portal using either the Log stream or by downloading the default_docker.log file from Advanced tools.

Troubleshooting

Here are the most common failure scenarios and solutions:

  1. The subscription (AZURE_SUBSCRIPTION_ID) doesn't have access to the Azure OpenAI Service. Please ensure AZURE_SUBSCRIPTION_ID matches the ID specified in the OpenAI access request process.

  2. You're attempting to create resources in regions not enabled for Azure OpenAI (e.g. East US 2 instead of East US), or where the model you're trying to use isn't enabled. See this matrix of model availability.

  3. You've exceeded a quota, most often number of resources per region. See this article on quotas and limits.

  4. You're getting "same resource name not allowed" conflicts. That's likely because you've run the sample multiple times and deleted the resources you've been creating each time, but are forgetting to purge them. Azure keeps resources for 48 hours unless you purge from soft delete. See this article on purging resources.

  5. You see CERTIFICATE_VERIFY_FAILED when the prepdocs.py script runs. That's typically due to incorrect SSL certificates setup on your machine. Try the suggestions in this StackOverflow answer.

  6. After running ./app/start.ps1 on Windows PowerShell you get The file C:\path\to\azure-search-openai-demo-java\app\start.ps1 is not digitally signed. You cannot run this script on the current system. Try to run Set-ExecutionPolicy -Scope Process -ExecutionPolicy Bypass and try to re-run ./app/start.ps1

  7. After running ./app/start.ps1 or ./app/start.sh you get "Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.10.1:compile (default-compile) on project myproject: Fatal error compiling: invalid target release: 17". It means you are not using JDK 17 but a previous version. Be sure to set the JAVA_HOME env variable to your Java 17 installation directory and update your PATH env variable to have the Java 17 bin folder as the first occurrence amongst the listed directories. More info here

  8. After running ./app/start.sh on Ubuntu 16.04 or later, the first time you try to create a virtual environment with Python 3.6, Python 3.7, Python 3.8 or Python 3.9, you'll get the following error "The virtual environment was not created successfully because ensurepip is not available". Just follow the hint provided in the error message and run apt-get install python3-venv to install the missing packages. More info here

  9. While running azd up in VS Code Dev Containers you got this error ".. Maven: failed finding mvnw in repository path: exec: /azure-search-openai-demo-java/app/backend/mvnw: permission denied ". Run chmod +x ./azure-search-openai-demo-javaapp/backend/mvnw to fix it and rerun azd up.

  10. Github App CI pipeline might fail in some scenarios where the provisioned App Service instance doesn't have "Basic Auth Publishing Credentials" enabled in your subscription. To fix it, you can go to your App Service instance in Azure Portal, click on "Settings/Configuration(Panel)->General Settins (Tab)" and flag to ON the "Basic Auth Publishing Credentials" checkbox group. Or you can run the following azd cli commands:

    az resource update --resource-group <resource-group> --name ftp --namespace Microsoft.Web --resource-type basicPublishingCredentialsPolicies --parent sites/<site-name> --set properties.allow=true
    az resource update --resource-group <resource-group> --name scm --namespace Microsoft.Web --resource-type basicPublishingCredentialsPolicies --parent sites/<site-name> --set properties.allow=true
