Oracle® TopLink Examples EJB 2.0 CMP

This example demonstrates how to use TopLink EJB 2.0 container-managed persistence (CMP) entity beans with relationships on Oracle Containers for J2EE (OC4J).

A browser-based client accesses multiple instances of TopLink-enabled persistent EJB types through a servlet. The EJBs are stored in a database which is accessed through the server connection facilities. The example demonstrates how to:

Configuration Requirements

Before you build and run the example, follow the minimum configuration requirements for your environment in Configuring the Examples.

Building and Running the Example

Use the following commands to build the example, reset the database, start the server and run the example:

To build the deployable EAR file, execute the build file. For Windows, select the build.cmd file. For UNIX, select the build.sh file. The build file invokes the build.xml ANT script, which retrieves supporting properties from the env.properties file and builds the example.
Ensure the database is running.
To reset database tables for this example, execute the resetDatabase file. For Windows, select the resetDatabase.cmd file. For UNIX, select the resetDatabase.sh file.
Start the OC4J server. When you start the server, set the system property toplink.log.level to "FINE" to turn on logging. For example, java -Dtoplink.log.level="FINE" -jar oc4j.jar.
To deploy the EAR file after server startup, execute the deploy file. For Windows, select the deploy.cmd file. For UNIX, select the deploy.sh file.
Double click the startClient.htm file or start a browser and point it to http://localhost:8888/cmp20-relationships/mainPage.jsp.

Note:

If you are using Internet Explorer and you change something in the file system, select View > Refresh before double clicking a *.cmd file in the Windows (filesystem) Explorer that IE provided. The *.cmd file will then execute correctly.
