I have had a Ruby xmlrpc/server instance running for awhile now. Using both Ruby and Python xmlrpc client apps I have been able to successfully pass information back and forth. Trying a Dolphin Smalltalk xmlrpc client app I had to tweak their implemention a bit since it wasn't passing 'Content-Type: text/xml' in the HTTP header and apparently the Ruby xmlrpc/server instance requires this to be set. After doing so the Dolphin Smalltalk xmlrpc client worked as well. But now I am having issues getting a SuperWaba xmlrpc client to receive the information back from the Ruby xmlrpc/server instance. This implementation is based on Apache's xmlrpc 1.0 library so it should be pretty standard. Is there something that's incompatible that anyone is aware of? I can see the xmlrpc calls being received on the Ruby xmlrpc/server end, and can see a result set/code being passed back out to the xmlrpc client. But that's where it ends. The SuperWaba xmlrpc client reports back an unexpected response from the server with a null error code. I know that this might be more of a client issue than a server one, but has anyone run into problems getting the Ruby xmlrpc/server communicating with other types of clients?

Here is one thing I noticed looking into this deeper: I can see things process okay on the Ruby xmlrpc/server, but it's where the response is being passed back to the client where the problems occur. I can successfully pass information back and forth with the Ruby xmlrpc/server using other clients, such as Ruby, Python, and Smalltalk xmlrpc clients. But just not with this SuperWaba xmlrpc client. I used Ethereal to trace the TCP packets being passed and the successful clients get a reply from the xmlrpc server, but the xmlrpc4sw clients don't receive the response over the wire. The only difference I see in the POST http header coming from the clients is that the SuperWaba xmlrpc client is passing a Accept-Encoding: identity parameter, whereas the other clients aren't. Could this be causing the problem since my Ruby xmlrpc/server isn't using any encoding or authentication? Is there any option for enabling this encoding/authentication on the Ruby end to test it out?

What I did was rebuild the SimpleHttpClient.java file on the xmlrpc client end. I commented out the 'Accept-Encoding: identity' parameter that was being added to the HTTP header. Once I did now I can see the Ruby xmlrpc/server passing back the result set to the client. That is one less thing to worry about. Now all I have to do is get the client to parse the result set and use the data :-)

Can someone please tell me what default parser is being used by Ruby to generate the xmlrpc response? Perhaps the parser being used by my client isn't matching up right...
