Creating an empty business-level application using programming
You can create an empty business-level application, and then add assets or business-level applications as composition units to the empty business-level application.
Before you begin
This task assumes a basic familiarity with command framework programming. Read about command framework programming in the application programming interfaces documentation.
You can create an empty business-level application using programming, the administrative console, or the wsadmin tool.
About this task
Perform the following steps to create an empty business-level application using programming. In your code that creates the empty business-level application, you must provide the name parameter. The name parameter specifies the name of the business-level application that you create.
Procedure
Results
After you successfully run the code, the empty business-level application is created.
Example
The following example shows how to create an empty business-level application based on the previous steps. Some statements are split on multiple lines for printing purposes.

What to do next
You can add business-level applications or assets as composition units into the newly created business-level application. Alternatively, you can add the newly created business-level application to other business-level applications.
