Hi, there are lot of problems with SOAP 2.2. This error might be of 2 reasons 1. You have not exposed the method in Deployment descriptor. 2. The class has not been put in the web-inf classes . if not, try using the xml apache for soap 1.4 version. This should solve the problem.

I dont know what this means. I have programmed my client originally for useage with Apache SOAP 2.0, but it should work woth SOAP 2.2 as well, because I think SOAP 2.2 is down compatible....or I am wrong???
