	In Eclipse, the cause of this problem is that You somehow deleted the SYSTEM JRE LIBRARY associated with your project. Simple fix in Eclipse: -Right Click Project you are working on from Package Explorer -Go to Properties -Go to Java Build Path from the right tree structure -Go to Libraries Tab -Choose Add Library Button -Select JRE System Library -Hit Next, the Radio button will prompt the Workspace default JRE, and let it be that way -Hit Finish Things should work now Cheers, -Ram S.

It worked for me.
