BBjServletData

Description

In BBj 12.0 and higher, the BBjServletData object allows your program to register callbacks for incoming web requests.

When the webserver first receives a request registered with the BBjServletRegistry, an interpreter will be started with the registered BBjAppConfig. That application then registers handlers for callback events. BBjServletData provides a handle to the internal configuration for registering callbacks.

The BBjServletData object is obtained through the following BBjAPI method:
