Using the Java Source Editor and Syntax highlight in any JEditorPane

On the my new JSF Palette Components I've been doing, It allows users get any BackingBean (bean) from the Project, to make it possible, I was looking for on NetBeans Dev Wiki. And I get this entry: http://wiki.netbeans.org/wiki/view/DevFaqEditorJEPForMimeType . However, I think this might works on NetBeans 6.0, cause doing like this entry says ...

EditorKit kit = CloneableEditorSupport.getEditorKit("text/x-java");
JEditorPane jep = new JEditorPane();
jep.setEditorKit(kit);

I in fact did not have success. But, NetBeans Platform, offers great resources, as I did something similar to Greenbox for NetBeans , I did the following code for what I was needing:

      /** Creates new form JavaCodePanel */
    public JavaCodePanel() {
        initComponents();
        beanCode.setContentType("text/x-java");
        EditorKit kit = JEditorPane.createEditorKitForContentType("text/x-java");
        kit.install(beanCode);
        beanCode.setEditorKit(kit);
    }

On the code the beanCode is a JEditorPane, and now this will have the same actions you can see on default Java Editor.
