java.io.StreamCorruptedException: invalid stream header: 54657374 -

i trying read string send client using socket program, code follows:

import java.io.ioexception; import java.io.objectinputstream; import java.io.objectoutputstream; import java.lang.classnotfoundexception; import java.net.serversocket; import java.net.socket;  public class socketserverexample {      //static serversocket variable     private static serversocket server;     //socket server port on listen     private static int port = 5000;      public static void main(string args[]) throws ioexception, classnotfoundexception{         //create socket server object         server = new serversocket(port);         //keep listens indefinitely until receives 'exit' call or program terminates         while(true){             system.out.println("waiting client request");             //creating socket , waiting client connection             socket socket = server.accept();             //read socket objectinputstream object             objectinputstream ois = new objectinputstream(socket.getinputstream());             //convert objectinputstream object string             string message = (string) ois.readobject();             system.out.println("message received: " + message);             //create objectoutputstream object             objectoutputstream oos = new objectoutputstream(socket.getoutputstream());             //write object socket             oos.writeobject("hi client "+message);             //close resources             ois.close();             oos.close();             socket.close();             //terminate server if client sends exit request             if(message.equalsignorecase("exit")) break;         }         system.out.println("shutting down socket server!!");         //close serversocket object         server.close();     }  } 

but getting error follows while reading string client:

exception in thread "main" java.io.streamcorruptedexception: invalid stream header: 54657374     @ java.io.objectinputstream.readstreamheader(objectinputstream.java:803)     @ java.io.objectinputstream.<init>(objectinputstream.java:298)     @ socketserverexample.main(socketserverexample.java:29) 

i searched , not managed find bug. please me.

clearly aren't sending data objectoutputstream: writing bytes.

• if read readobject() must write writeobject().
• if read readutf() must write writeutf().
• if read readxxx() must write writexxx(), values of xxx.
