Hi
I am not sure if I can come with any useful for you, but I would try
changing the argument to you function call from Vector to Object[]. My
server runs Apaches XML-RPC and I have managed to use it with both
xml-rpc for c and for c++.

Hello,
I have problems connecting an apache java xml-rpc client with a xmlrpc-c C++
xml-rpc server (system is ubuntu linux 8.04).
The client code is modified from the first example at
http://www.wordtracker.com/docs/api/ch03s02.html.
The server code is
http://xmlrpc-c.svn.sourceforge.net/viewvc/xmlrpc-c/trunk/examples/cpp/xmlrpc_sample_add_server.cpp?revision=1083&view=markup
When running the client (after server is started) I get:
Exception
in thread "main" org.apache.xmlrpc.client.XmlRpcHttpTransportException:
HTTP server returned unexpected status: Not Found

The
java client can communicate with a server from the same apache package,
and the C++ server can communicate with a C++ client from the same
xmlrpc-c package. What can be the reason for the incompatibilities
between java and C++?
Here are the sources for completeness:
Java client Client.java:
================
import org.apache.xmlrpc.XmlRpcClient;
import java.util.Vector;
public class Client {
public static void main( String args[] ) throws Exception {
XmlRpcClient client = new XmlRpcClient( "http://localhost:8080/" );
Vector params = new Vector();
params.addElement( 5 );
params.addElement( 7 );
Object result = client.execute( "sample.add", params );
if ( result != null )
System.out.println( "Successfully pinged guest account." );
}
}
C++ server xmlrpc_sample_add_server.cpp:
================================
#include <cassert>
#include <stdexcept>
#include <iostream>
#ifdef WIN32
# include <windows.h>
#else
# include <unistd.h>

using namespace std;

class sampleAddMethod : public xmlrpc_c::method {
public:
sampleAddMethod() {
// signature and help strings are documentation -- the client
// can query this information with a system.methodSignature and
// system.methodHelp RPC.
this->_signature = "i:ii";
// method's result and two arguments are integers
this->_help = "This method adds two integers together";
}
void
execute(xmlrpc_c::paramList const& paramList,
xmlrpc_c::value * const retvalP) {
int const addend(paramList.getInt(0));
int const adder(paramList.getInt(1));
paramList.verifyEnd(2);
*retvalP = xmlrpc_c::value_int(addend + adder);
// Sometimes, make it look hard (so client can see what it's like
// to do an RPC that takes a while).
if (adder == 1)
SLEEP(2);
}
};
int
main(int const,
const char ** const) {
try {
xmlrpc_c::registry myRegistry;
xmlrpc_c::methodPtr const sampleAddMethodP(new sampleAddMethod);
myRegistry.addMethod("sample.add", sampleAddMethodP);
xmlrpc_c::serverAbyss myAbyssServer(
myRegistry,
8080, // TCP port on which to listen
"/tmp/xmlrpc_log" // Log file
);
myAbyssServer.run();
// xmlrpc_c::serverAbyss.run() never returns
assert(false);
} catch (exception const& e) {
cerr << "Something failed. " << e.what() << endl;

return 0;
