PermGen error

After recently working on a new web application project, it came to a stage where I had to download the project at home on my personal machine. So of course I logged into our SVN and grabbed a copy.

After getting the project there was an error in the project:

Cannot nest 'Project/src/main/java' inside library 'Project/src

I knew previously that this error wasn’t occuring. As far as the project classpath is concerned there was only one src path which correctly pointed at the folder Project/src/main/java

After searching through the project I found out the issue – in the .settings folder there is a file named:

org.eclipse.wst.common.component

You should find you have a line similar to the following:

<wb-resource deploy-path="/WEB-INF/classes" source-path="/src"/>

To fix simply remove that line (and if you don’t have it already, add the line):

<wb-resource deploy-path="/WEB-INF/classes" source-path="/src/main/java"/>
