Hi,
It looks like when you are running webservice it is not able to find some reference classes you might have missed to include one or more jar files while deploying the web service on server thats might be the  reason as when you are running Java class it is working fine.
please follow below process and check if anything is missing.
Right click on project -> Properties -> Java Build Path
at this place you can see the reference projects and jar files in different tabs
go to tab Order & Export and see if the desired jar file is selected or not if not select it and deploy the application again.
