I'm using xdoclet within eclipse to generate the ejb descriptors and local/remote/session classes. I've recently hit a problem on my project where I get a OutOfMemoryError during the generation. This is using eclipse europa on windows xp.
The xdoclet plugin seems to use ant so the suggestion in the error message is to increase the memory available to ant using the ANT_OPTS property. I'm not sure how to get eclipse to recognise this property? I've done some searching via google and couldn't find anything useful. The xdoclet plugin doesn't seem to have much in the way of configuration options and if I set the ANT_OPTS in the Windows environment variables, eclipse doesn't seem to recognise it!
I've discovered a way of manually running the xdoclet build by using the tempAnt.xml ant build file that eclipse produces in the \workspace\.metadata\.plugins\ directory of the xdoclet plugin but am sure there must be a better way of doing this.
