[Prameela <prameela.kumar@xxxxxxxxxxx>]

hi ,
I am trying to do add  JavaCapabilityConfigurationPage to a wizard.
as following.  But without success.

COde:

public void addPages()
    {
        IProject project = null;
        JavaCapabilityConfigurationPage confPage = new 
JavaCapabilityConfigurationPage();
        confPage.init(JavaCore.create(project),null,null,false);
        addPage(confPage);

    }

Problem :
 1) while trying to launch the wizard it is throwing "NoClassDefFoundErr"
  2) Another Unrelated problem is I am unable luanch my plugin as 
runtime workbench.

Thanx  a lot
