Ant properties, perhaps? XDoclet supports the use of these in the tags.
If you're going to generate multiple DDs, you're going to have to run
the task/subtask multiple times. So, just use e.g.
@jboss.sql type="${jboss.sql.typex}"
in your tag, and before each run of the task have it read in a different
properties file, where the different properties file have the relevant
values each database. No need for any tinkering.
At least, that's the theory. I've never actually tried it myself, so
your mileage may vary... Let us know how you get on.
