dbforms tag library installed
DevGui successfully run against my database, saved the dbforms-config.xml and the
generated table jsp files using dbforms.
Fired it up, tomcat manager reports successful install of the application. When I put
in the URL I get a big bad exception. Changing the name of the tag library url proves
that the tag library is loading.
I'm pretty new to servlets and jsp. How do you troubleshoot? I don't think I can get
at file DbFormTag.java?
