NetBeans 6.8/6.7 UML Class Diagrams

i have tried to generate Class Diagrams in NetBeans 6.7 and 6.8 but all i get is:

i figured out installing UML for 6.8 here: NetBeans 6.8 UML

i have followed the instructions here: UML Class diagrams

i so far i failed to generate anything meaningful.

i have followed the tips:

Open your project, then create a new UML project (choose "Reverse Engineered Java-Platform model"). After that all your classes will be available in the UML project under "Model". You can now create a new class diagram and drag your classes from "Model" onto the diagram.

but nothing meaningful happens when i drag my classes to the Class Diagrams. it alw开发者_运维问答ays represents the classes as "datatype" on the diagram and class info is not displayed.

any helpful tips regarding how can i fix this? or another way of generating Java class diagrams?

thank you for your time.

EDIT: NetBeans 6.5.1 is working perfectly. thanks!

As pointed out here there is no solution for 6.7 try a lower version (e.g. 6.5) or try Visual Paradigm ... here is one snippet of a good comment:

the UML module was discontinued in the default distribution of Netbeans after 6.5 and instead they now recommend visual paradigm(VP),
