You can uninstall an application through the administrative console, the wsadmin tool, or programming. Use this example to uninstall an application through programming.
Before you can uninstall an application on WebSphere Application Server, you must first install it.
Perform the following tasks to uninstall an application through programming.
The following example shows how to uninstall an application based on the previous steps. Some statements are split on multiple lines for printing purposes.
