The registerOutputHTTPVariable() method registers a program variable with a specific structure, that will be used to fill the HTTP response headers when a Web Operation is completed.
In case of error, the method throws an exception and sets the STATUS variable. Depending on the error, a human-readable description of the problem is available in the SQLCA.SQLERRM register. See Error handling in GWS calls (STATUS).
