I tried almost each and everything written all around the web without result.
So, i had to call IT team to re-install O.S. and now it's working fine.
I am marking this thread as solved.
Reinstalling the O.S. seems a little extreme to me. The "missing" class should be in the lib/server-api.jar file in Tomcat. You might have been able to solve this by reinstalling Tomcat or reinstalling Eclipse.

Peter, i did that almost 50 times with no result that's why i had to re-install OS.
