Did you change the server environment any? In particular, did you copy the soap.jar somewhere new? You should only have a single place from which your servlet container can load the Apache SOAP classes, and it should be the webapp into which you deployed Apache SOAP. Different locations from which the container load classes are serviced by different class loaders, which causes serious problems.
