Hi Tim,

Thanks for responding so promptly.

I have followed your advice although I set MaxPermSize to 512m for eclipse
and Geronimo. These settings can be seen in the ps output I posted.

The artifact I am developing is an experimental EAR. It includes 3 jsp's but
it includes Hibernate POJO's, EJB3 session beans and a Struts presentation
layer.

The EAR deploys and runs fine under Eclipse. However it generally fails with
a PermGen Space error on the 2nd deployment. Not so good for development. I
am running on a laptop however it has 2 GB RAM.

Please email me your address and I will send you the EAR. However this might
not be for a couple of weeks. as I'm just going on holiday. I will send you
my email address separately.

Many thanks for your help,

Steve
