The UML plugin for Netbeans IDE is generating no results just empty folders!

Please, When i am trying to reverse engineering my project (from .java to UML) under netbeans, I am receiving just a set of empty folders. Any ideas about what possibly the problem can be?

I am running Netbeans IDE 6.9.1. The UML was supporte开发者_JAVA技巧d in the previous version, though it is possible to install it manually on the new version too.

Thanks in advance for your help!

Netbeans 6.9 doesn't work with UML diagrams. You need to switch back to the 6.5 version or to Eclipse.

go back to 6.8, UML diagrams still visible. Trick: Just open project and then "NEW diagram", "OLD diagrams" will be recovered!!!.
