JGUP 1.0 has been released.

JGUP is a code generation tool for getting a head start on a new J2EE
web application project. You supply a XML file describing the web
application and JGup creates your database tables and outputs a project
source tree. The project source tree includes an Ant build.xml for
compiling and deploying the web application.  Java objects for
persisting to the db are generated, and simple relations between
business objects are supported, including: one to one, one to many, and
many to many.  The generated web application includes a Servlet/JSP
user interface with input prompt validation done both by JavaScript and
by servlet.  An administrator's web page, for viewing the logs and
setting configuration parameters, is also included in the web
application.

JGup supports WebLogic and Oracle. JGup is not a full circle
development tool. You generate the code once and then modify as needed.
JGup is released under the GPL. This covers the tool itself- not the
code you may generate with it.
