The kitchensink-ml
quickstart demonstrates a localized Java EE 7 compliant application using JSF, CDI, EJB, JPA, and Bean Validation.
What is it?
The kitchensink-ml
quickstart is a deployable Maven 3 project to help you get your foot in the door developing with Java EE 7 on Red Hat JBoss Enterprise Application Platform.
It demonstrates how to create a localized Java EE 7 compliant application using JSF, CDI, JAX-RS, EJB, JPA, and Bean Validation. 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.
-
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 `src/main/resources/org/jboss/as/quickstarts/kitchensink/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:src/main/resources/org/jboss/as/quickstarts/kitchensink/util/KitchensinkMessages.i18_(es|fr).properties
-
The message bundle consumed by Bean Validation is located at
src/main/resources/ValidationMessages.properties
. This is defined by the bean validation specification.
-
-
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>fr</supported-locale> <supported-locale>fr-FR</supported-locale> <supported-locale>es</supported-locale> <supported-locale>es-ES</supported-locale> </locale-config> <resource-bundle> <base-name>org/jboss/as/quickstarts/kitchensink/bundle/Resources</base-name> <var>bundle</var> </resource-bundle> </application>
-
The
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
src/main/java/org/jboss/as/quickstarts/kitchensink/util/KitchensinkMessages.java
file was created, which defines default messages in English. Thejboss-logging-processor
will automatically generate an implementation for you, which can be accesssed via theMESSAGES
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
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
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.
Considerations for Use in a Production Environment
- H2 Database
-
This quickstart uses the H2 database included with Red Hat JBoss Enterprise Application Platform 7.1. It is a lightweight, relational example datasource that is used for examples only. It is not robust or scalable, is not supported, and should NOT be used in a production environment.
- Datasource Configuration File
-
This quickstart uses a
*-ds.xml
datasource configuration file for convenience and ease of database configuration. These files are deprecated in JBoss EAP and should not be used in a production environment. Instead, you should configure the datasource using the Management CLI or Management Console. Datasource configuration is documented in the Configuration Guide for Red Hat JBoss Enterprise Application Platform.
System Requirements
The application this project produces is designed to be run on Red Hat JBoss Enterprise Application Platform 7.1 or later.
All you need to build this project is Java 8.0 (Java SDK 1.8) or later and Maven 3.3.1 or later. See Configure Maven to Build and Deploy the Quickstarts to make sure you are configured correctly for testing the quickstarts.
Use of EAP_HOME
In the following instructions, replace EAP_HOME
with the actual path to your JBoss EAP installation. The installation path is described in detail here: Use of EAP_HOME and JBOSS_HOME Variables.
Start the JBoss EAP Standalone Server
-
Open a terminal and navigate to the root of the JBoss EAP directory.
-
Start the JBoss EAP server with the default profile by typing the following command.
$ EAP_HOME/bin/standalone.sh
NoteFor Windows, use the EAP_HOME\bin\standalone.bat
script.
Build and Deploy the Quickstart
-
Make sure you start the JBoss EAP server as described above.
-
Open a terminal and navigate to the root directory of this quickstart.
-
Type the following command to build the artifacts.
$ mvn clean package wildfly:deploy
This deploys the kitchensink-ml/target/kitchensink-ml.war
to the running instance of the server.
You should see a message in the server log indicating that the archive deployed successfully.
Access the Application
The application will be running at the following URL: http://localhost:8080/kitchensink-ml/.
Change your browser preferred language to French or Spanish and refresh the page to see it displayed in the new language.
Server Log: Expected Warnings and Errors
You will see the following warnings in the server log. You can ignore these warnings.
WFLYJCA0091: -ds.xml file deployments are deprecated. Support may be removed in a future version.
HHH000431: Unable to determine H2 database version, certain features may not work
Undeploy the Quickstart
When you are finished testing the quickstart, follow these steps to undeploy the archive.
-
Make sure you start the JBoss EAP server as described above.
-
Open a terminal and navigate to the root directory of this quickstart.
-
Type this command to undeploy the archive:
$ mvn wildfly:undeploy
Run the Arquillian Tests
This quickstart provides Arquillian tests. By default, these tests are configured to be skipped since Arquillian tests require the use of a container.
Note
|
The Arquillian tests deploy the application, so make sure you undeploy the quickstart before you begin. |
Follow these steps to run the tests.
-
Start the JBoss EAP server as described above.
-
Open a terminal and navigate to the root directory of this quickstart.
-
Type the following command to run the
verify
goal with thearq-remote
profile activated.$ mvn clean verify -Parq-remote
Note
|
You can also let Arquillian manage the JBoss EAP server by using the |
Run the Quickstart in Red Hat JBoss Developer Studio or Eclipse
