Creating rcp application with some features from knime

 I was trying to plugin some features(Views, editors etc) from knime to my eclipse rcp application. 
 I was able to include Node Repository view to the application by adding the dependant plugins.
 But it did not list the nodes.
 Then I tried to include workflow projects view which is included in org.knime.workbench.ui. I added all  dependencies, but i could not include org.knime.workbench.ui in my application.
  After adding this plugin the application could not start.

 Could you please give me an answer whether is it possible? 

It's hard to tell without having more details. But you should always install complete features and not individual plug-ins, because plug-ins may heavily depend on each other and not work correctly otherwise.
