JAXB - permGen error on Tomcat server

I am getting the below error when running my deployed app. Going by the error, it seems JAXB is causing it. Please suggest. 

java.lang.OutOfMemoryError: PermGen space

Solution

  • Increase the size of your perm space first. This link shows you how.

    Monitor your memory usage with Visual GC to see how this helps.

    If it doesn't, get rid of JAXB. I shy away from it for exactly this reason. Better to do your OXM by hand than rely on it.
