Activating and Deactivating
Applications 
With the Enable and Disable functions you can activate or deactivate Web Dynpro applications.
No Web Dynpro application is started when the J2EE Engine is started. The following process is triggered when a user calls the Web Dynpro application:
· If the application is deactivated, the user receives an error message and the Web Dynpro application cannot be called, whether the runtime status of the application is stopped or started.
·
If the application
is activated, the Web Dynpro runtime environment starts the application
if the runtime status of the application is started.
If the runtime status is stopped, the Web Dynpro runtime environment tries to start
the application nevertheless; that is, it tries to call the application
anyway. Any applications that are referenced are also started.
