And I didn't fully understood it either ;-)

Which one did you have to change ? I just use the same classes,
with the same tags, for Oracle, DB2 and HypersonicSQL. Every
difference is hidden in properties files inside the castor-doclet.jar
file (well, except for the fact that HSQL doesn't support sequences...)

Xdoclet seems nice, but dedicated to EJBs, isn't it ? How does
it handle classes order in the mapping file (with dependent
objects, you have to be very carefull) ?
