Please use the CVS version of the XDoclet module which is way improved
over the rc5 version (you don't have to use OJB from CVS, only the XDoclet
module). You can get it from the ViewCVS access from the OJB website
(http://cvs.apache.org/viewcvs/db-ojb/). Download the three jars
xdoclet-1.2.jar, xdoclet-ojb-module-1.2.jar, and xjavadoc-1.0.2.jar from
the lib folder, and also the documentation (xdoclet.xml) from the xdocs
folder (html is build via 'ant htmldoc').
If the problem persists, please post the stacktrace that the CVS
module version generates.
As for the stacktrace, I can't do much about it, XDoclet 1 is not known
for its user-friendly error messages. A conversion to XDoclet 2 is
planned for OJB 1.1 though.
