Look this framework (https://code.google.com/p/lindbergframework/). Easy handling of stored procedures and functions, including treatment of cursors automatically.

Of course!

First you need to configure. To configure, follow the guide shown here

Example:

Classes for example:







Table for example:



Procedures Definition for example:



Procedures Definition in linp-sqlMapping.xml file for example:



DAO for example:



You must configure and initialize the context of the framework. See the user guide for how to do this for web application and which are not.

Any questions, please reports it.

But this list of examples only advertises your product. How does it explain the OP's NullPointerException? You mean that the OP wouldn't get that NPE with your framework?
