The message means that Jess called a method of your
CustomerAppliedPool object, and it threw an exception. Jess could not
continue, so Jess is reporting the exception to you.
The JessException object you're catching has a method getCause(). In
your exception handler, you need to call getCause(), and if it returns
non-null, then it will be the exception referred to in the message
above. Call printStackTrace on this second exception object, and you
will find out what is going wrong in your code.
