What is it?

Note: Hibernate 3.x is not a supported configuration in Red Hat JBoss Enterprise Application Platform 6.1 or later.

The sole purpose of this quickstart is to help you understand the changes needed to move your application from Hibernate 3.x to Hibernate 4. This quickstart has the same functionality as the hibernate4 quickstart but uses the Hibernate 3 libraries. Compare this quickstart to the hibernate4 quickstart to see the code and class differences between Hibernate 3 and Hibernate 4.

This quickstart, like the log4j quickstart, demonstrates how to define a module dependency. However, this quickstart goes beyond that and also demonstrates the following:

  • WAR creation - The Maven script and Maven WAR plugin create a WAR archive that includes ONLY the Hibernate 3.x binaries. To understand better how this is achieved, please refer to the pom.xml in the root directory of this quickstart. Additional information can be found in the http://maven.apache.org/plugins/maven-war-plugin documentation.
  • Module exclusion and inclusion - This example demonstrates how to control class loading using dependencies and exclusions in the jboss-deployment-structure.xml file. For more information about this file, please refer to https://docs.jboss.org/author/display/AS7/Developer+Guide#DeveloperGuide-JBossDeploymentStructureFile
  • Persistence configuration - Configuration is required to tell the container how to load JPA/Hibernate.

System requirements

The application this project produces is designed to be run on Red Hat JBoss Enterprise Application Platform 6.1 or later.

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

Note: This quickstart uses the H2 database included with JBoss EAP 6. It is a lightweight, relational example datasource that is used for examples only. It is not robust or scalable and should NOT be used in a production environment!

Configure Maven

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

Start the JBoss Server

  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:

     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 install jboss-as:deploy
    
  4. This will deploy target/jboss-hibernate3.war to the running instance of the server.

Access the application

The application will be running at the following URL: http://localhost:8080/jboss-hibernate3/.

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 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
