Hi,
(I don't like to say this but it really is an URGENT matter)

I'm trying to integrate a server written in C++, through Web Services 
(AxisC++/Apache1.3 for Windows 2003 Server), with a java application. 
I've already developed both of them, and i actually already deployed 
the Web Service in Apache (copied the .dll, etc).

This was the wsdl from which I generated the stubs/skeletons:

<?xml version="1.0" encoding="UTF-8"?>
<wsdl:definitions targetNamespace="http://DefaultNamespace"; 
xmlns:apachesoap="http://xml.apache.org/xml-soap"; 
xmlns:impl="http://DefaultNamespace";

xmlns:soapenc="http://schemas.xmlsoap.org/soap/encoding/"; 
xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/"; 
xmlns:wsdlsoap="http://schemas.xmlsoap.org/wsdl/soap/"; 
xmlns:xsd="http://www.w3.org/2001/XMLSchema";>

It seemed that I've done everything alright, at least i followed the 
developer guides! BUT when i try to run the client application this 
returns an exception:

               java.lang.ClassCastException

From the server side all maintains like nothing happened...i've put 
lots of prints for debugging but none of them appears on the server 
side! The strange is that the Apache log is changed, the requests are 
written in Access Log and Apache "says" the return code is 200!
Anyone can help me!!! I don't know if it is a client side problem or a 
server side...How can i fix this?

You could use tcpmon from Axis Java to track the request and response 
SOAP messages. Use that tool to see if the request goes to the server 
and if the server sends the correct response.
