I have to make a web service client from an wsdl file. I have followed tutorial to create and test the service client in the eclipse wizard, and (I thought that I have implemented the code to call the service), but I keep getting this stack trace, I know its maybe trivial but I didn't manage to find anything on internet. I have attached these libraries to the path, so i cant understand what this is, I appreciate any help, first time dealing with web services. I am not sure if it is ok to post entire stack trace here, its quite big, but here is part of it.....
