You guys might want to check out Describe which also has a version built on the Forte
IDE. The only problem is that this thing has a single developer price tag of about $3000. You can get a fully functional 30 day trial version though, which should be long enough to get your design done on the developer assignment.
This thing keeps up with all your javadoc comments and doesn't trash the code it generates with junk comments like Rational Rose does. I have accesee to it at work which makes it real nice.
Hope this helps
