Stopping a business-level application using programming
You can stop a business-level application, which stops each composition unit in that business-level application. Each composition unit is stopped on the respective targets on which the business-level application is deployed.
Before you begin
Before you can stop a business-level application, you must have created an empty business-level application, imported an asset, added a composition unit to the business-level application, and started the business-level application.
About this task
You can stop a business-level application using programming, the administrative console, or the wsadmin tool. The steps describe how to stop a business-level application using programming.
Perform the following steps to stop a business-level application using programming.
Procedure
Results
After you successfully run the code, the business-level application is stopped.
Example
The following example shows how to stop a business-level application based on the previous steps. Some statements are split on multiple lines for printing purposes.

What to do next
Complete administrative tasks on the business-level application, such as editing an asset or a composition unit that is contained in the business-level application.
