About Assembly and Deployment Events

The deployment tools that are provided by Enterprise Server can be used by anyone to deploy applications and modules into any Enterprise Server environment. However, effective application deployment requires planning and care. Only the developer knows exactly what is required by an application, so the developer is responsible for initial assembly and deployment.

1. Deployment Descriptor Creation. The developer creates the deployment descriptors using Java standards and tools.

   Details of the Enterprise Server-specific deployment descriptors are contained in Appendix B, Enterprise Server Deployment Descriptor Files and Appendix C, Elements of the Enterprise Server Deployment Descriptors. The Enterprise Server–specific sample applications contain deployment descriptors that can be used as templates for developing deployment descriptors.

2. Assembly. The developer assembles the archive file(s) using Java standards and tools, such as the jar command. The application or module is packaged into a JAR, WAR, RAR, or EAR file. For guidelines on naming, see Naming Standards.

   There are no Enterprise Server–specific issues to consider.

3. Test Deployment. The developer performs a test deployment of the archive. For instructions, see To Deploy an Application or Module.

4. Archive Submission. The developer submits the verified archive to the administrator for deployment into a production environment. The developer includes instructions for any additional deployment tasks that the administrator must perform. For an example of such additional instructions, see Access to Shared Framework Classes.

5. Configuration. The administrator applies additional deployment specifics. Sometimes the developer has indicated additional deployment needs, such as specifying the production database. In this case, the administrator edits and reassembles the archive.

6. Production Deployment. The administrator deploys the archive to production. See To Deploy an Application or Module.

7. Troubleshooting. If deployment fails, the administrator returns the archive to the developer. The developer fixes the problem and resubmits the archive to the administrator. Sometimes the administrator resolves the problem, depending on what the problem is.
