This week's book giveaway is in the OCMJEA forum. We're giving away four copies of OCM Java EE 6 Enterprise Architect Exam Guide and have Paul Allen & Joseph Bambara on-line! See this thread for details.
The section on class loaders is in Volume 3, which is not going to see the light of day for at least another year. I would be reluctant to share what I have now because this is a complex subject, and I have not looked at my stuff in ages. I have never read his book, but Stuart Dabbs Halloway is a really great guy who helped edit my Java Rules book in print. It may seem like an unlikely candidate, but I have heard said that his chapter on class loaders in "Component Development for the Java Platform" is particularly insightful. Like I said, though, I never read it, and I haven't spoken with Stuart in a long time, but I distinctly recall someone saying this.
