kitchensink-ml: Localized application using an assortment of technologies including Arquillian

Author: Sande Gilda Level: Intermediate Technologies: CDI, JSF, JPA, EJB, JPA, JAX-RS, BV Summary: A localized version of kitchensink Target Product: EAP

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. 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 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.

    • They are located in the src/main/resources/org/jboss/as/quickstarts/kitchensink-ml/bundle directory.

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

  • The following XML was added to the 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-ml/bundle/Resources</base-name>
            <var>bundle</var>
        </resource-bundle>
    </application>
    
  • The src/main/java/org/jboss/as/quickstarts/kitchensink/util/Resources.java file was modified to add the ResourceBundle producer that loads the correct resource bundle using the browser preferred locale.

    @Produces
    public ResourceBundle produceResourceBundle() {
        return ResourceBundle.getBundle("org.jboss.as.quickstarts.kitchensink-ml.bundle.Resources", FacesContext
                .getCurrentInstance().getViewRoot().getLocale());
    }
    
  • The src/main/java/org/jboss/as/quickstarts/kitchensink/controller/MemberController.java file was modified as follows:

    • It injects the ResourceBundle.

      @Inject
      private ResourceBundle resourceBundle;
      
    • Messages strings were replaced with strings retrieved using the resource bundle property names. For example:

      FacesMessage m = new FacesMessage(FacesMessage.SEVERITY_INFO, 
                                  (String) resourceBundle.getObject("registeredMsg"), 
                                  (String) resourceBundle.getObject("registerSuccessfulMsg"));
      
  • The index.xhtml and template.xhtml files were modified.

    • The following namespace was added: xmlns:f="http://java.sun.com/jsf/core
    • The resource bundle was loaded using: <f:loadBundle basename="org.jboss.as.quickstarts.kitchensink-ml.bundle.Resources" var="bundle" />
    • 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.war 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/.

Change your browser preferred language to French or Spanish and refresh the page to see it displayed in the new language.

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:

    mvn clean test -Parq-jbossas-remote 
    

Run the Quickstart in JBoss Developer Studio or Eclipse

You can also start the server and deploy the quickstarts from Eclipse using JBoss tools. For more information, see Use JBoss Developer Studio or Eclipse to Run the Quickstarts

Debug the Application

If you want to debug the source code or look at the Javadocs of any library in the project, run either of the following commands to pull them into your local repository. The IDE should then detect them.

mvn dependency:sources
mvn dependency:resolve -Dclassifier=javadoc
