Java classpath issues

So I had a strange issue today. I was getting classpath exceptions. Turns out turning off the JQS on Windows XP fixed it.

But it got me wondering how this works. Here are some links for my own reference:

• Dustin's Java development tools blog post
  
• The jps tool.
• Jconsole
• Actually using Jconsole
• ClassNotFoundException vs. NoClassDefFoundError
• IBM DeveloperWorks articles on Classpath:
