This will not help much, but did you test it in steps - i.e. first
test on your local machine - and with the stored procedure's java code
in a class on your local machine rather than a jar in the database?
But you've probably already done that?

In eclipse you might be able to suspend the run by putting a
breakpoint in the source, then 'attaching' to the appropriate
suspended thread...

The tomcat installation should point you to where it's starting
networkserver, and you might be able to add some debugging/tracing
properties to a derby.properties file (to be created) in that
Helpful derby.properties settings are:
More detailed errors should then show up in a derby.log file somewhere
on the server.

There are also tracing properties you can switch on for network server
and client - check the  manual
