Uninstalling an application through programming

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 begin

This task assumes a basic familiarity with MBean programming. For information on MBean programming see MBean Java application programming interface (API) documentation.

Before one can uninstall an application on WebSphere Application Server, first install it.



Perform the following tasks to uninstall an application through programming.



  1. Get a connection to WebSphere Application Server.

  2. Get the application management proxy.

  3. Create the notification filter for listening to uninstallation events.

  4. Add the listener.

  5. Uninstall the application.

  6. Wait for some timeout so that the program does not end.

  7. Listen to Java Management Extensions (JMX) notifications to understand completion of the operation.

  8. When the uninstallation is done, remove the listener and quit.



After you successfully run the code, the application is uninstalled.



The following example shows how to uninstall an application based on the previous steps. Some statements are split on multiple lines for printing purposes.
