How to Generate Class Diagram from existing classes in Netbeans IDE

Question

I have created java entity classes inside a given package. I want to create a UML diagram for those java classes in the package. Any one know how to do it in NetBeans IDE 7? (I installed the plugin and it is working.)

Solution

For those using Netbeans version 8, take a look at these plugins

easyUml -> http://plugins.netbeans.org/plugin/55435/easyuml

PlantUml ->http://plugins.netbeans.org/plugin/49069/plantuml

Visual Paradigm is a software which also helps in generating UML diagrams.
