[pde-ui-dev] Problem with starting the plugin

[Prameela Kumar <pkumar@xxxxxxxxxxxxxxxxxxxxxxxxx>]

  I am new to eclipse plugin development and need some help.
Context:
  I made some tiny plugins and tried to install them with the help 
of  "HELP" which worked fine.
  Now I am trying to make a plugin extending the View.

The Problem:
  When I first start the IDE , these new plugins I added are not 
integrated. But ,when I launch a new workbench from the IDE, all these 
plugins appears and works absolutely as expected.

Please advice what I am doing wrong.  : (

Thanks in advance.
