Simple SOAP Client only works locally

[Bob DuCharme <bo...@udico.com>]

I got an Apache SOAP server up and running following the directions in
Graham Glass's excellent articles at
http://www-106.ibm.com/developerworks/library/ws-peer2/ (and /ws-peer3/) and
I got his sample client up and running successfully. To understand SOAP
clients better, I wrote a general purpose client more geared to XML geeks
like myself that reads in a file with the XML of a SOAP request envelope,
sends it off to the SOAP server, and then reads back and outputs the SOAP
response envelope, all without using the Apache SOAP libraries.

It works when I run it against the Apache SOAP server from the machine where
the server is running and from a different machine on the same intranet, but
it doesn't work against a client like the XMethods' weather-temperature one
at http://www.xmethods.com/detail.html?id=8. I have successfully run the
sample client from that same page against XMethods' temperature SOAP server,
so I know I can access that endpoint, but when I use my SimpleSOAPClient
below to send the sample request envelope from that page to the SOAP
endpoint URL shown, I don't get any response. It gets stuck at the
connection.getInputStream() line.

Any suggestions as to what I'm doing wrong?

Apache SOAP structures and WSDL

[Joel Riedesel <jr...@jnana.com>]

To send a structured element to an Apache SOAP server, it must
be correctly typed.

Where oh where might one find that information from a WSDL file?

(Not the top level 'input' namespace data, but if an input message
part is a complex type...)

Thanks,

Joel
