I create a new plugin in eclipse and run it in as a seperate eclipse application , the new worbench opens successfully but when I click the menu which I created by defining actionsets in plugin.xml, my plugin doesn't run neither it shows any error.
when I debug the code which runs by clicking the menu,
the debugger comes up to this line of code only ;
Display disp= new Display();

I include all swt jars in runtime , still it says that ClassLoader is unable to load
swt.widget;

please suggest
Thanks

If you are creating a RCP application then the SWT plugins shall be added as a required plugins.
The SWT jars are added to class path when you wish to create a Java application and want to use SWT
to create UI.
