chainsaw with CustomSQLDBReceiver

[karen]

I am using CustomSQLDBReceiver with chainsaw. When chainsaw is
launched,
I am getting a null pointer exception. Any thoughts on what the issue
might be?

I have included my configuration file below.

The execution of the job threw an exception
java.lang.NullPointerException
