Appengine Error

My local google appengine suddenly started giving the following error while it is getting started....... I have cross checked all my jar files, they are perfectly placed and available in the classpath, none of the jar is present for twice etc and even struts configuration file is present in the classpath, it was perfectly working an hour before with the same setup, I did nothing in my work space during this time, .... it is very veered.
