c++ - Java XML RPC Client and server -

i trying communicate client , server in 1 project client , server both started in main() of project having 2 different threads when client try call answer_is function of server side show below exception. when run client , server combined in 1 project got error

here code project 1 having client , server

main class

package serverclienttest;  /**  *  * @author root  */ public class serverclienttest {      /**      * @param args command line arguments      */     public static void main(string[] args) {         // todo code application logic here         try {             serverthread serverthread =  new serverthread();             thread t = new thread(serverthread);             t.start();             clientthread clientthread = new clientthread();             thread t1 = new thread(clientthread);             t1.start();          } catch (exception exception) {             system.err.println("webclientserver: " + exception);         }     }  } 

clientside

package serverclienttest; import java.net.url; import java.util.map; import java.util.scanner;  import java.util.vector;  import java.util.*;  import java.io.*; import java.net.*;  import org.apache.xmlrpc.client.xmlrpcclientconfigimpl; import org.apache.xmlrpc.client.xmlrpcclient; import java.util.*; import java.io.*;  /**  *  * @author root  */ public class clientthread implements runnable{     public void run()     {          try {         // xmlrpcclient server = new xmlrpcclient("http://localhost/rpc2");            xmlrpcclient client = new xmlrpcclient();              xmlrpcclientconfigimpl config = new xmlrpcclientconfigimpl();             config.setserverurl(new url("http://localhost:5300/rpc2"));             config.setenabledforextensions(true);          //vector params = new vector();        /*  hashtable params = new hashtable();        params.put(1, 1);          params.put(2, 2);*/          object[] testclass = new object[]{1,2};          client.setconfig(config);          int result = (integer) client.execute("sample.sum", testclass);          system.out.print("client executed");          int sum = ((integer) result).intvalue();          system.out.println("the sum is: "+ sum);        } catch (exception exception) {          system.err.println("javaclient: " + exception);       }     } } 

server side

public class serverthread {        public serverthread() {         system.out.println("handler registered answer_is");    }     public integer sum(int x, int y){        return new integer(x+y);    }    public void run()     {        try {        system.out.println("attempting start xml-rpc server...");           webserver server = new webserver(5300);           server.addhandler("sample", new serverthread());          server.start();           system.out.println("started successfully.");          system.out.println("accepting requests. (halt program stop.)");         }         catch (exception exception){          system.err.println("javaserver: " + exception);       }  } 

but when wrote server side in project , run , work fine plz tell me why client , server not run in same project

"unexpected end of file server" implies server accepted , closed connection without sending response. it's possible system busy handle request, or there's bug randomly drops connections.

in serverclienttest class, invoking: serverthread serverthread = new serverthread(); thread t = new thread(serverthread);

without implementing runnable. try changing class signature below:

public class serverthread implements runnable
