I've just moved to Middlegen-hibernate-r5, but, when i generate the hbm, i receive this error in the log (and no hbm file is generated):

So, i''ve tryed to use the r4 release with the same config files (i've changed only library files), and i can get hbm files.

If you need, i can post here my build.xml plugin configurations.

THANKS!

Did you check on the library libs (all dependent ones). It looks like a velocity lib error. The build I released really has few changes to the dep libs etc from that of R4. I'm really not sure whats wrong with your environment.

OOPS! I've copyed all libs from hibernate extension 2.1.2, to make work hbm2java task (also some old libs)...

Removing this all work good :D!

THANS!

Only another question:
How can i set cascade property for relationship?

You can set the cascade option globally through the Ant script.
eg, under the hibernate plugin add cascade="save-update". I have to document this and the other new options.

Thanks! :D
