kitchensink-ml-ear: Localized Example Using Multiple Java EE 6 Technologies Deployed as an EAR

Author: Sande Gilda Level: Intermediate Technologies: EAR Summary: A localized version of kitchensink-ear Target Product: EAP Source: https://github.com/jboss-jdf/jboss-as-quickstart/

What is it?

This is your project! It is a sample, deployable Maven 3 project to help you get your foot in the door developing with Java EE 6 on JBoss Enterprise Application Platform 6 or JBoss AS 7.

This project is setup to allow you to create a localized Java EE 6 compliant application using JSF 2.0, CDI 1.0, EJB 3.1, JPA 2.0 and Bean Validation 1.0. A localized application is one that supports multiple languages. That is what the -ml suffix denotes in the quickstart name kitchensink-ml-ear. This quickstart also includes a persistence unit and some sample persistence and transaction code to introduce you to database access in enterprise Java.

This quickstart uses the kitchensink-ear quickstart as its starting point. It has been enhanced to provide localization of labels and messages. A user sets the preferred language choice in the browser and, if the application supports that language, the application web page is rendered in that language. For demonstration purposes, this quickstart has been tranlated into French(fr) and Spanish (es) using http://translate.google.com, so the translations may not be ideal.

Localization Code Changes

The following changes were made to the quickstart to enable it to use the browser preferred locale setting when displaying the web page:

  • Properties files were created for the supported languages.

    • This quickstart is localized for Spanish and French. You can add additional language support by creating properties files with the appropriate suffix and populating the properties with translated values.

    • The JSF resource Bundle is located at `jboss-as-kitchensink-ml-ear-web/src/main/resources/org/jboss/as/quickstarts/kitchensink-ml/bundle/Resources_(es|fr).properties

    • Messages generated by Java code (e.g. log messages and messages sent to the UI) are internationalized using JBoss Logging. The log messages are accessed via the org.jboss.as.quickstarts.kitchensink.util.KitchensinkMessages interface, and the message bundles are located at: jboss-as-kitchensink-ml-ear-ejb/src/main/resources/org/jboss/as/quickstarts/kitchensink/util/KitchensinkMessages.i18_(es|fr).properties

    • The message bundle consumed by Bean Validation is located at `jboss-as-kitchensink-ml-ear-ejbsrc/main/resources/ValidationMessages.properties' (this is defined by the bean validation specification).

  • The following XML was added to the jboss-as-kitchensink-ml-ear-web/src/main/webapp/WEB-INF/faces-config.xml file. When you create a property file for a new language, you must add the supported locale to this file.

      <application>
    <locale-config>
          <default-locale>en</default-locale>
          <supported-locale>en-US</supported-locale>
          <supported-locale>es</supported-locale>
          <supported-locale>ES-FR</supported-locale>
          <supported-locale>fr</supported-locale>
          <supported-locale>fr-FR</supported-locale>
      </locale-config>
      <resource-bundle>
          <base-name>org/jboss/as/quickstarts/kitchensink_ear/bundle/Resources</base-name>
          <var>bundle</var>
      </resource-bundle>
  </application>

  • The jboss-as-kitchensink-ml-ear-ejb/src/main/java/org/jboss/as/quickstarts/kitchensink/model/Member.java file was modififed to add the message key to @Pattern annotation.

       @NotNull
   @Size(min = 1, max = 25)
   @Pattern(regexp = "[A-Za-z ]*", message = "{name_validation_message}")
   private String name;

  • The jboss-as-kitchensink-ml-ear-ejb/src/main/java/org/jboss/as/quickstarts/kitchensink/util/KitchensinkMessages.java file was created, which defines default messages in English. The jboss-logging-processor will automatically generate an implementation for you, which can be accesssed via the MESSAGES static variable.

      @MessageBundle(projectCode = "")
  public interface KitchensinkMessages {
  
     KitchensinkMessages MESSAGES = Messages.getBundle(KitchensinkMessages.class, FacesContext.getCurrentInstance().getViewRoot().getLocale());
  
     @Message("Registered!")
     String registeredMessage();
 
     @Message("Successfully registered!")
     String registerSuccessfulMessage();
  
     @Message("Registration failed:")
     String registerFailMessage();
  
     @Message("Registration failed. See server log for more information.")
     String defaultErrorMessage();
  }

  • The jboss-as-kitchensink-ml-ear-web/src/main/java/org/jboss/as/quickstarts/kitchensink/controller/MemberController.java file was modified as follows:

    • Messages strings were replaced with strings retrieved using the resource bundle property names. For example:

        FacesMessage m = new FacesMessage(FacesMessage.SEVERITY_INFO, 
          KitchensinkMessages.MESSAGES.registeredMessage(),
          KitchensinkMessages.MESSAGES.registerSuccessfulMessage());

  • The jboss-as-kitchensink-ml-ear-web/src/main/webapp/index.xhtml file were modified.

    • Strings for headers, messages, labels were replaced with the appropriate # {bundle.<property>}, for example: # {bundle.memberWelcomeHeader}.

Set the Browser Preferred Locale

How you set your browser preferred locale depends on the browser and version you use. Use your browser help option to search for instructions to change the preferred language setting.

System requirements

All you need to build this project is Java 6.0 (Java SDK 1.6) or better, Maven 3.0 or better.

The application this project produces is designed to be run on JBoss Enterprise Application Platform 6 or JBoss AS 7.

Configure Maven

If you have not yet done so, you must Configure Maven before testing the quickstarts.

Start JBoss Enterprise Application Platform 6 or JBoss AS 7 with the Web Profile

  1. Open a command line and navigate to the root of the JBoss server directory.

  2. The following shows the command line to start the server with the web profile:

     For Linux:   JBOSS_HOME/bin/standalone.sh
 For Windows: JBOSS_HOME\bin\standalone.bat

Build and Deploy the Quickstart

NOTE: The following build command assumes you have configured your Maven user settings. If you have not, you must include Maven setting arguments on the command line. See Build and Deploy the Quickstarts for complete instructions and additional options.

  1. Make sure you have started the JBoss Server as described above.

  2. Open a command line and navigate to the root directory of this quickstart.

  3. Type this command to build and deploy the archive:

     mvn clean package jboss-as:deploy

  4. This will deploy target/jboss-as-kitchensink-ml-ear.ear to the running instance of the server.

Access the application

The application will be running at the following URL: http://localhost:8080/jboss-as-kitchensink-ml-ear-web.

  1. Enter a name, email address, and Phone nubmer in the input field and click the Register button.

  2. If the data entered is valid, the new member will be registered and added to the Members display list.

  3. If the data is not valid, you must fix the validation errors and try again.

  4. When the registration is successful, you will see a log message in the server console:

     Registering _TheNameYouEntered_

Undeploy the Archive

  1. Make sure you have started the JBoss Server as described above.

  2. Open a command line and navigate to the root directory of this quickstart.

  3. When you are finished testing, type this command to undeploy the archive:

     mvn jboss-as:undeploy

Run the Arquillian Tests

This quickstart provides Arquillian tests. By default, these tests are configured to be skipped as Arquillian tests require the use of a container.

NOTE: The following commands assume you have configured your Maven user settings. If you have not, you must include Maven setting arguments on the command line. See Run the Arquillian Tests for complete instructions and additional options.

  1. Make sure you have started the JBoss Server as described above.

  2. Open a command line and navigate to the root directory of this quickstart.

  3. Type the following command to run the test goal with the following profile activated:
