This is often seen when a NullPointerException is thrown at startup, or even just a misconfigured portlet.

Go back to basics. There's probably something wrong with the code. Check your code into a SCM repository, and then start stripping things back until it works. Then add things back in until you find the problem.

Good luck!

yes. There was mis configuration between my portlet.xml and portlet class. My portlet class has extended generic portlet. So Just followed JSR 168 portlet specification. Now the problem has been resolved.
