java.lang.reflect.InvocationTargetException in web service for GrFinger application to match fingerprints
===

 I m using GrFinger application to match the fingerprints .Locally the application runs well through 'main' method. But when I create web service out of it. It shows following exception while calling 'Util" class constructor. Can anybody please help to solve the problem. I have already included all the jar files and .dll files . But the problem is still the same.
thanks.
