• JMX! Instrumenting for JMX is easy - and we've forthcoming articles on it. I'd like to see more in-depth treatment, though, as it's a core component of the new J2EE specification, and many application servers already use it - but I want to see how it can be made available, as well as case studies of how people have used it in the "real world" outside of the rarified atmosphere of specific applications. It's an enterprise tool, and much underused, in my opinion.
  
• J2EE solutions would be cool as well. One person suggested an article on "top ten urban legends about J2EE," which sounds like a chance to dispel the myths that have grown up it. Any others?
  
• Articles on profiling effectively, as well as writing clear code that performs well, would be excellent reads.
  
• JNDI is another technology that's vastly misunderstood and misunderused by the "rank and file." Anyone want to write up a useful primer on it?
  
• I'd love to see tips and tricks for Swing and Java2D, with performance and clarity in mind.
  
• An article on using some of the many scripting languages now floating about might be useful to our readers as well, such as how they're usable for real-world projects and products.
  
• EDI is underaddressed. (Really! Everything I've read addresses how the technologies work, and not why you should use them.)
  
• Are there interesting tools and libraries for Java? Of course there are. Components, too. If you'd like to take a swing at explaining or exposing one of them, feel free!

These are just a few ideas you might be interested in. If you have others, please don't let this list stop you!

It's a lot of fun to watch things come through, and if we've been less responsive than you'd like, we apologize! I've been on vacation lately, as well as having a lot of high-priority items in my day job, so I've simply had less working time to dedicate to you. As things slow down, we'll be able to pick up the slack again.

That said, keep them coming!
