You can delete a business-level application using programming. You might delete a business-level application if it is not functioning correctly, it is no longer needed, and so on.
This task assumes a basic familiarity with command framework programming. Read about command framework programming in the application programming interfaces documentation.
Before you can delete a business-level application, you must have created an empty business-level application. You can optionally have added assets or business-level applications as composition units to the empty business-level application. All the composition units in the business-level application must be deleted using the deleteCompUnit command before you delete the business-level application. Other business-level applications cannot reference the business-level application that you are deleting. Otherwise, the deletion fails.
You can delete a business-level application using programming, the administrative console, or the wsadmin tool.
You must specify the blaID parameter of the business-level application that you are deleting. You might delete a business-level application if it is not functioning correctly, no longer needed, and so on.
Perform the following steps to delete a business-level application using programming.
After you successfully run the code, the business-level application is deleted.
The following example shows how to delete a business-level application based on the previous steps. Some statements are split on multiple lines for printing purposes.

You can complete other tasks associated with business-level applications, such as creating other business-level applications, stopping and starting business-level applications, and so on.
