I have configured a subclass of RESTHandler in my web.xml and have overridden the processRequest method to add a call to DataSource.addDynamicDSGenerator to register my ds generator. But when I make a POST request I get this null pointer error.
The content of my http POST looks correct.
What could be causing the npe?
Code:
