A J2EE application can be packaged as an archive file and then be deployed to an application server.
An application is packaged by providing it with deployment profile and deployment descriptor files. Deployment descriptors define the content and organization of the deployed applications. Deployment descriptor files that are required by an application depend on the technologies the application uses and on its target application server.
An application can be tested on the embedded OC4J server without being packaged or deployed. Simply run or debug the application in JDeveloper. A packaged application can be deployed to standalone OC4J for testing, or to Oracle Application Sever or various other production application servers.
The following topics describe target-independent aspects of J2EE packaging and deployment:
