richfaces-validation: RichFaces and Bean Validation

Author: Lukas Fryc Level: Beginner Technologies: RichFaces Summary: Demonstrates RichFaces and bean validation Target Product: WFK

What is it?

This quickstart demonstrates how to use JSF 2.0, RichFaces 4.2, CDI 1.0, JPA 2.0 and Bean Validation 1.0.

It consists of one entity, Member, which is annotated with JSR-303 (Bean Validation) constraints. In typical applications, these constraints are checked in several places:

  • As database constraints
  • In the persistence layer
  • In the view layer (using JSF / Bean Validation integration)
  • On the client (using RichFaces 4.2 - Client Side Validation)

This ensures the constraints are applied consistently, across all layers, allowing clear and precise error reporting, while not breaking the DRY (Don't Repeat Yourself) principle.

This quickstart does not contain a persistence layer. It only shows integration of RichFaces, JSF and Bean Validation. The validation is done using client-side validation where possible.

The application contains a view layer written using JSF and RichFaces and includes an AJAX wizard for new member registration. Each member needs to complete the following information in the wizard:

  • e-mail
  • name and phone
  • confirmation of supplied information

Once users are successfully registered, they are redirected back to the initial page with a message that the registration was successful.

This quickstart also includes tests for all Bean Validation constraints for the Member entity. This allows you to check constraints without without the need for a view layer. The tests are written using the Arquillian framework.

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-richfaces-validation.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-richfaces-validation/.

You will be provided with form to enter member information.

  • Enter an Email address and click on Continue. If the Email address is not valid, you will see an error message saying "Not a well-formed Email address"
  • On the next page, you must enter a Name and Phone number. A valid name must be between 1 and 25 characters in length. A valid phone number must be between 10 and 12 digits in length.
  • Click Confirm to register the member.

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

Investigate the Console Output

When you run the tests, JUnit will present you test report summary:

Tests run: 5, Failures: 0, Errors: 0, Skipped: 0

If you are interested in more details, check target/surefire-reports directory. You can check console output to verify that Arquillian had really used the real application server. Search for lines similar to the following in the server output log:

[timestamp] INFO [org.jboss.as.server.deployment] (MSC service thread 1-2) Starting deployment of "test.war"
...
[timestamp] INFO [org.jboss.as.server] (management-handler-threads - 1) JBAS018559: Deployed "test.war"
...
[timestamp] INFO [org.jboss.as.server.deployment] (MSC service thread 1-3) Stopped deployment test.war in 48ms
...
[timestamp] INFO [org.jboss.as.server] (management-handler-threads - 1) JBAS018558: Undeployed "test.war

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
