It is nice to have one example that works.

Do you have a working example for a cgi server?

SOAP itself looks to be simple enough, looking like a variant of XML (which for me is quite familiar). But, it is the communication between the client and server which doesn't seem so simple. For example, it looks like the core problem I have with the WSDL file for which I have the URL, appears to be the use of complex data types. It is clear to me that the call I quoted from the working PHP script has created definitions of two classes, and that the second argument to SOAPClient is some kind of array with pointers or a map to the class definitions. I have not found anything that is obviously similar to that in Perl's various SOAP packages. Suppose I wanted to create a server and a client that handled peronal IDs and addresses, and started by creating a person class and an address class (with the peerson class having an address as a data member). How would I create the server to both receive such data and how would I write the client so that it knows about these classes? I don't know PHP that well, but I assume my perl SOAP client would not be able to connect to the server unless it includes the class definitions when it first tries to connect (mimicing what the PHP code seems to do). But then, the question is, how do I do that?
