Apache's Java XMLRPC library

I am using my XML-RPC service using Apache XML-RPC library but in reponse of XML-RPC has junk character so library can not parse the result

Here, is my XML-RPC program:

import java.net.URL;

import org.apache.xmlrpc.client.XmlRpcClient;
import org.apache.xmlrpc.client.XmlRpcClientConfigImpl;


public class XMLRpcExample {

    public static void main(String[] args) throws Exception{
        // TODO Auto-generated method stub

        XmlRpcClientConfigImpl cf = new XmlRpcClientConfigImpl();
        cf.setServerURL(new URL("/xmlrpc/object"));
        cf.setBasicUserName("admin");
        cf.setBasicPassword("m_demo");
        cf.setConnectionTimeout(60000);
        XmlRpcClient client = new XmlRpcClient();
        client.setConfig(cf);
        Object[] params = new Object[] {"dbname",1,"m_demo","res.partner","partner_sync_openerp","kapil5drd@bxiz","22"};
        String s =(String)client.execute("execute", params);
        System.out.println(s);
    }

}

But I am getting this error in response, which looks like this: 

[Fatal Error] :16:16: An invalid XML character (Unicode: 0xc) was found in the element content of the document.
Exception in thread "main" org.apache.xmlrpc.client.XmlRpcClientException: Failed to parse server's response: An invalid XML character (Unicode: 0xc) was found in the element content of the document.

    at org.apache.xmlrpc.client.XmlRpcStreamTransport.readResponse(XmlRpcStreamTransport.java:200)
    ... 8 more

The XML-RPC gives a junk character in reponse.

And the library itself fails to parse the response.

So it means, Apache XML-RPC library is it self unable to parse the response.

Can any body help me with what I need to do?

I have also tried to fix this issue via the internet but I am unable to solve it.

Here is the working example for your parameters, which can help you

Handler Class:

public class Handler {
    public String execute(String dbName, Integer i, String a, String b, String c, String d, String e){
        System.out.println("Got inputs: "+dbName+", "+i+", "+a+", "+b+", "+c+", "+d+", "+e);
        return "<?xml version=\"1.0\"> <test>[email protected]</test>";
    }
}

More such handlers can be added using phm.addHandler("handler",Handler.class); to the server code. More methods can be added to this class and can be called from client.

XMLRPC Server:

import org.apache.xmlrpc.server.PropertyHandlerMapping;
import org.apache.xmlrpc.server.XmlRpcServer;
import org.apache.xmlrpc.server.XmlRpcServerConfigImpl;
import org.apache.xmlrpc.webserver.WebServer;

public class Server {
    private static final int port = 8080;

    public static void main(String[] args) throws Exception {
        WebServer webServer = new WebServer(port);
        XmlRpcServer xmlRpcServer = webServer.getXmlRpcServer();
        PropertyHandlerMapping phm = new PropertyHandlerMapping();
        phm.addHandler("handler",Handler.class);
        xmlRpcServer.setHandlerMapping(phm);
        XmlRpcServerConfigImpl serverConfig =
                (XmlRpcServerConfigImpl) xmlRpcServer.getConfig();
        serverConfig.setEnabledForExtensions(true);
        serverConfig.setContentLengthOptional(false);
        webServer.start();
    }
}

XMLRPC Client:

import org.apache.xmlrpc.client.XmlRpcClient;
import org.apache.xmlrpc.client.XmlRpcClientConfigImpl;

import java.net.URL;

public class Client {
    public static void main(String args[])throws Exception{
        XmlRpcClientConfigImpl cf = new XmlRpcClientConfigImpl();
        cf.setServerURL(new URL("http://localhost:8080/xmlrpc/object"));
        cf.setBasicUserName("admin");
        cf.setBasicPassword("m_demo");
        cf.setConnectionTimeout(60000);
        XmlRpcClient client = new XmlRpcClient();
        client.setConfig(cf);
        Object[] params = new Object[] {"dbname",1,"m_demo","res.partner","partner_sync_openerp","kapil5drd@bxiz","22"};
        String s =(String)client.execute("handler.execute", params);
        System.out.println(s);
    }
}
