Task overview: Using enterprise beans in applications

Complete the following tasks to use enterprise beans in a Java™ based application.

1. EJB 3.x beans: Design a Java Platform, Enterprise Edition (Java EE) application and the enterprise beans that it needs.
2. EJB 2.x beans: Design a Java 2 Platform, Enterprise Edition (J2EE) application and the enterprise beans that it needs.
3. Develop any enterprise beans that your application uses.
   See the topic Developing enterprise beans.
4. Prepare for assembly. For your EJB 2.x-compliant entity beans decide on an appropriate access intent policy.
   For more information about using access intent, see the topic, Using access intent policies for EJB 2.x entity beans.
5. Assemble the beans into one or more EJB modules using one of the assembly tools.
   See the topic Assembling EJB modules.

   This process includes setting security. See the topic Securing enterprise bean applications to learn more about setting the security.

   For your EJB 2.x-compliant entity beans, you might also want to designate container-managed persistence (CMP) sequence groups. See the topic Setting the run time for CMP sequence groups.

6. EJB 3.x beans: Assemble the beans into one or more EJB 3.x modules using one of the assembly tools.
   See the topic Assembling EJB 3.x modules.
7. Assemble the modules into a Java EE application using the assembly tool.
8. Update the EJB container configuration for a given application if needed for the application to be deployed.
9. Update the EJB container configuration for a given application server if needed for the application to be deployed, and determine if you want to batch commands or defer commands for container-managed persistence.
10. Deploy the application in an application server.
11. Test the modules.
    • As needed, debug problems with the container. For more information see the topic Enterprise bean and EJB container troubleshooting tips.
    • Debug access problems. See the topic Enterprise bean cannot be accessed from a servlet, a JSP file, a stand-alone program, or another client.
12. Assemble the production application using one of the assembly tools
13. Deploy the application to a production environment.
14. Manage the application:
    1. Manage installed EJB modules.
       After an application has been installed, you can manage its EJB modules individually through assembly tools.
    2. Manage other aspects of the Java application. See the topic Deploying and administering enterprise applications
15. Update the module and redeploy it using one of the assembly tools.
16. Tune the performance of the application. See the topic Best practices for developing enterprise beans.
