[Geoserver-devel] tomcat-postgresql communication

I am just getting started with this project. I've got all the pieces
installed correctly, I think. I've built geoserver. I've installed postgis
in postgresql (I can make maps using UMN Mapserver). I've installed tomcat
and deployed mapserver.war.
My problem is that when I try to test the system out using the wfsTest
utility, I get no response from geoserver. I've been doing some network
snooping and I notice that there is absolutely no TCP/IP communication with
Postgres (I know I've turned on TCP access, because Mapserver can use it).

Any help is appreciated. Thanks.
