Michael,
The permgen memory contains the class definitions, since you're probably using a big number of classes they get loaded into permgen. You can optimize the size by using custom classloaders with XMLBeans, which most likely is more complicated than increasing the permgen size and depends very much on the application, but XMLBeans doesn't do this by default.

We are using XMLGBeans 2.4.0 Kind Regards Michael If you are not the intended addressee, please inform us immediately that you have received this e-mail in error, and delete it.
