c++ WSDL2Ws creates an extra input parameter

[Ben Souther]

Hello,

I've used the WSDL2Ws tool that ships with Axis C++ to create a simple client
for a java webservice running on axis/tomcat.  The webservice method takes a 
string as it's only argument and returns the same string but in upper case.

The c++ method that gets generated has an extra input parameter, has a return 
type of void, and doesn't seem to work.

I tried commenting out the line with the second "m_pCall->AddParameter.." 
statement.
This improved things a bit.  I can now see that a call is being made.
I determined this with a System.out.println statement on the server which 
shows that the string is being passed from the c++ client to the webservice.

After that, the app just hangs for about 10 seconds and returns with the 
following message:

execution break
m_MsgSize == 0, so return NULL
Press any key to continue

Is Axis C++ interoperable with Axis Java?.
Do I need to tweak the WSDL to get this to work?

If the WSDL2Ws tool isn't generating the proper c++ code, does anyone know 
where there is an example of a working c++ client that calls an echoString 
type of webservice that I can use as a template?

Any help would be greatly appreciated.

Below is a copy of all relevant files:

====================================================
The Java WS Class:
====================================================
package filemanager.service;
public class EchoCaps{

    public String capitalize(String in){
        System.out.println("Value passed in from client: " + in);
        return in.toUpperCase();
    }
}

===========================================================
