JDBC operation throws a NullPointerException

Hi all...

It seems that any attempt to perform a jdbc access from a deployed LCA (my process at this point only contains the JDBC 'query multiple to xml' operation) results in the following exception on the LC server (see below). The query and xml generation all seem to work ok from the Workbench. I can mail the lca upon request. Thanks.
