I am using this in IOS. may be this code can help you a bit.
mPayMobilePayment *mpayMobilePayment =[mPayMobilePayment service];
//mPayMobilePayment is service name, and you will call getService method in the same way.
[mpayMobilePayment setBaseUrl:@"Enter your complete base url, you can get this url easily from soapUI tool as well"];
NSError *error;
NSArray *response = [mpayMobilePayment getSubscribedEntityServices:@"firt input value of method. input values will be auto generated" entityId:@"second input value of method" error:&error];
getSubscribedEntityServices" is my method name in service and this method is autogenerated by WSClient.
every code i wrote is auto generated by wsclient in its files. i just copied the files in my project and call them in the above decsribed way.
Hope this will help you out.
