Java client library example

Prerequisites

In order to execute the script to demonstrate java client library, you need to have java 1.8 and gradle build automation system installed. Once you have the prerequisites please follow the steps:

1. Run prepare.sh script to build iroha java library and compile proto files:

./prepare.sh

2. Build java client library using gradle.

3. Make sure you have running iroha on your machine. You can follow this guide to launch iroha daemon. Please run iroha from iroha/example folder, since java code uses keys from there.

Launch example

Code in TransactionExample.java does the following:

1. Assembles transaction from several commands using tx builder.
2. Signs it using keys from iroha/example folder.
3. Sends it to iroha.
4. Waits 5 secs and checks transaction's status using it's hash.
5. Assembles query using query builder.
6. Sends query to iroha.
7. Reads query response.

Launch it using gradle:

gradle run
