about these examples

These examples demonstrate different aspects of Enterprise JavaBeans. It's a good idea to run all of these examples before attempting to create your own Enterprise JavaBeans. They will show you the different steps involved.

The examples demonstrate:

Building and running the examples

  1. Read the instructions for each example, found at the links above.

  2. Set up your development environment as described in Setting your development environment.

  3. Depending on the example, set up any special properties, such as database persistence.

  4. Build each example, using the provided build scripts or make file. We've provided instructions on using the build scripts.

    Certain examples build .jar files that contain multiple beans:

    Note that certain examples depend on other beans being built first:

  5. You can deploy each EJB in one of two ways:


    Note: If you're running under the Microsoft SDK for Java, you'll also need to add the path to the .jar to the CLASSPATH for your WebLogic Server.

  6. Run the example following the instructions for the example.
