Constructing a J2EE application from artifacts
The free-form configuration allows you to create or drop your J2EE artifacts or module files into a free-form project directory. J2EE artifacts can include the source, annotated-source, or class files of servlets, JSP files, static Web content, Web filters, Web listeners, enterprise beans, and other generic files. The rapid deployment tools automatically place your artifacts in the appropriate J2EE project structure, generate any additional required artifacts to construct a J2EE compliant application, and deploy that application on a target server.
About this task
Restriction: We can use the rapid deployment tools for packaging applications at J2EE 1.3 or 1.4 specification-levels. However, the rapid deployment tools do not support Java EE 5.0 (or later) nor J2EE 1.2 specification-level. For tools support of deploying Java EE 5 and later modules, you can use the monitored directory starting in WAS V8.0 release. For more details about the monitored directory, see Ways to install enterprise applications or modules and Installing enterprise application files by adding them to a monitored directory topics.
Procedure
To construct a J2EE application from artifacts:
- Set up a WebSphere rapid deployment environment
We can run the rapid deployment batch tools from a command line to create, configure, and launch rapid deployment projects using the IBM WebSphere v6.0 or later runtime environment. The rapid deployment tools run in a non-graphical command-line interface.- Create a free-form project in your workspace
The free-form project allows the creation of a J2EE application using a single project directory for development. Free-form development releases you from having to maintain multiple projects as well as having to understand the J2EE application structure.- Start a WebSphere rapid deployment session
We can launch a rapid deployment session to start listening for application artifacts that are dropped into the folder you configured for either the free-form or automatic installation approach. Use the wrd command to launch a rapid deployment session. To monitor rapid deployment activities, you can specify console output.- Drop J2EE artifacts into a free-form project
We can place application artifacts in a free-form project and let the rapid deployment tools automatically place them in the appropriate J2EE project structure, generate any additional required artifacts to construct a J2EE compliant application, and deploy that application on a target server.
