Hi All;
I have a rather big project with a dozen of dependent jar files. To ease development, I tried to put some of the jar files in the domains/domain1/lib directory for 2 reasons:
To decrease the time it takes for deploy/re-deployment during the development.
To decrease the chance of getting OutOfMemoryError PermGen stuff as I am getting it quite often.
After doing some research, it seams decreasing the classes that are loaded/re-loaded with each redeployment helps! I may be wrong, but i would like an explanation if anyone has a suggestion. I don't mind the large jar size if I don't get the PermGen error. I am getting an exception:
Building SessionFactory failed. java.lang.NoClassDefFoundError

this goes on and on.
I am sure I have the jar file org/jdesktop/beans/AbstractBean in the web-inf/lib. I even tried to put the hibernate related jars in the lib and still getting the error.
Any help is greatly appreciated.
Thanks
Kamal
