java.lang.OutOfMemoryError: PermGen space

[yj4jboss]

Hello,
We are currently developing a small application with Hibernate, Seam and Facelets. We often get the "java.lang.OutOfMemoryError: PermGen space" error when hot deploying applications several times during development.

I would like to know possible causes for this error and how to solve it.


Load of thnx in advance,
