Avoid Permgen Space error when running Tomcat from Eclipse

Question

What is the best way to avoid permgen space error when running Tomcat from Eclipse 3.6? Is this done by adding the following line:

-XX:MaxPermSize=512m

at the end of eclipse.ini? Or is there extra configuration necessary?

Answer 1

The configuration in eclipse.ini is only for the JVM that actually runs Eclipse.

Tomcat is run in its own JVM instance, so you'll need that separately.

Assuming you use WTP to start your Tomcat instance, you need to go to your Server configuration, click "Open launch configuration" and there (on the "Arguments" tab) edit/add the VM arguments to include the desired -XX:MaxPermSize argument.
