All Examples All EJB Examples
This example is a package that demonstrates an Enterprise JavaBean. Please run this example before attempting to create your own Enterprise JavaBeans, as it will show you the different steps involved. The example is a stateful session EJB called TraderBean.
The example demonstrates:
To get the most out of this example, first read through the source code files to see what is happening. Start with the XML deployment files to find the general structure of the EJB, which classes are used for the different objects and interfaces, then look at Client.java to see how the application works.
In general, you'll need to adjust certain properties to match your setup. You'll need to edit the entry for the property that begins with "weblogic.ejb.deploy" in the weblogic.properties file to deploy the EJB. The property is commented out in the default properties file; make sure that you uncomment out all the lines of the property.
This example is shipped "pre-built"; you can either run it as shipped, or build the example and run it to test that you are able to successfully build and run EJBs.
These three sections cover what to do:
We provide separate build scripts for Windows NT and UNIX:
These scripts will build the example and place the files in the correct locations:
We provide a commented-out version in the property that begins with "weblogic.ejb.deploy" that you can use. You'll need to adjust the property depending on which EJBs you're building and are deploying, or if the location of the files differs from the installed location.
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.
$ java examples.ejb.basic.statefulSession.Client
If you're not running the WebLogic Server with its default settings, you will have to run the client using:
$ java examples.ejb.basic.statefulSession.Client "t3://WebLogicURL:Port"
Parameters are optional, but if any are supplied, they are interpreted in this order:
