WAS v8.5 > Administer applications and their environment > Manage applications through programming

Edit applications

We can edit deployed applications through the dmgr console, wsadmin, or by programming. Use this example to edit a deployed application through programming.

This task assumes a basic familiarity with MBean programming. For information on MBean programming, see MBean Java API documentation. In this information center, click Reference > Mbean interfaces.

Before we can edit an application on WebSphere Application Server, install the application. Perform the following tasks to edit deployed application.

1. Connect to WAS.

2. Create the application management proxy.
3. Get information about an installed application.
4. Manipulate task data as necessary.

5. Save changes for the installed application.

Results

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

Example

The following example shows how to edit an application, based on the previous steps.
