Deploying GWT and using an different servlet for db access

[Ed]

Hi,
I am using GWT to create a front end to an existing servlet that
performs authentication form a ldap server or from a posgres db.

i have in jetty/webapps/SSISAJAX
jetty/webapps/SSISAJAXSERVER

SSISAJAX is the GWT application
SSISAJAXSERVER is just a servlet that implements the
UserServiceFactory which cannot be found.

I have put the SSISAJAXSERVER jar in the SSISAJAX gwt path with no
avail.

I hope this is not impossible with the toolkit.

Any help would be appreciated.

GWT 2.0.1

Below is the stack trace.
