So my simple cgi server program has been failing to deserialize test messages sent from a simple client program, both using SOAP::WSDL and the same WSDL file. It was fairly quickly apparent that the deserialization failed because types were missing in the generated typemap module. It took me much longer to figure out that the missing types are those that are sent in the header. (I'm not necessarily a whiz all the time.) Apparently SOAP::WSDL doesn't think it needs header types in the typemap, even though it DOES generate classes for them. Am I right about this? This seems like a bug ...? Anyway I'm going to try adding the required types manually with --typemap_include and see if that solves the problem.
