Edit: Since I can't pick two answers I'm going with the regex one because a) it's elegant and b) saying "Jon Skeet solved the problem" is a tau...

On the web page, it looks like there is no current development in the old style .doc. Is it good enough to create complex documents? Can it read all .docs without crashing?

The best treatment of the issues is in Horstmann's Core Java Vol 1. If equals() must always be overridden, then what i...

I also use the Commonclipse plugin to easily make use of the Apache Commons classes that build hashCode, toString, equals methods.

My company has been evaluating Spring MVC to determine if we should use it in one of our next projects. So far I love what I've seen, and right now I'm taking a look at the Spring Security module to determine if it's something we can/should use.
