Openfire Eclipse Project Builder Failed -

I have followed the instructions at

http://www.igniterealtime.org/community/docs/DOC-1020

This went fine upto Build Openfire then I follow

->Create Project Builder

->Run/Debug

• The setting is now complete for Openfire.
• You may test running and debugging by clicking on Run::Run History::Openfire and Run::Debug History::Openfirerespectively. If you choose the later and if you follow this instruction closely, execution will stop on the main method in ServerStarter.java.

-> After It showing Error :

Could not find main class:

org.jivesoftware.openfire.starter.ServerStarter Program will exit

I change Main class in Run configuration as java.org.jivesoftware.openfire.starter.ServerStarter I also showing the Same error

Help Me try out on two different machine from last 1 month, before 6 month I had successfully configured Openfire Dev in Eclipse and develop some plugins

Thanks in Advance
