Adding a file through programming
You can add a file to an existing application through the administrative console, the wsadmin tool, or programming. This example describes how to add a file 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. In this documentation, click .
Before you can add a file to an application on WebSphere® Application Server, you must install your application.
About this task
Perform the following tasks to add a file to an application through programming.
Procedure
- Connect to WebSphere Application Server.
- Create the application management proxy.
- Create the notification filter for listening to events.
- Add the listener.
- Add the file to the application.
- Wait for some timeout so that the program does not end.
- Listen to Java Management Extensions (JMX) notifications to understand completion of the operation.
- After you add a file, remove the listener and quit.
