I have a client Server application which communicate using objects.
when I send only one object from the client to server all works well.
when I attempt to send several objects one after another on the same stream I get
StreamCorruptedException.
Can some one direct me to the cause of this error?
client write method
private SecMessage[] send(SecMessage[] msgs)
{
SecMessage result[]=new SecMessage[msgs.length];
Socket s=null;
ObjectOutputStream objOut =null;
ObjectInputStream objIn=null;
try
{
s=new Socket("localhost",12345);
objOut=new ObjectOutputStream( s.getOutputStream());
for (SecMessage msg : msgs)
{
objOut.writeObject(msg);
}
objOut.flush();
objIn=new ObjectInputStream(s.getInputStream());
for (int i=0;i<result.length;i++)
result[i]=(SecMessage)objIn.readObject();
}
catch(java.io.IOException e)
{
alert(IO_ERROR_MSG+"\n"+e.getMessage());
}
catch (ClassNotFoundException e)
{
alert(INTERNAL_ERROR+"\n"+e.getMessage());
}
finally
{
try {objIn.close();} catch (IOException e) {}
try {objOut.close();} catch (IOException e) {}
}
return result;
}
server read method
//in is an inputStream Defined in the server
SecMessage rcvdMsgObj;
rcvdMsgObj=(SecMessage)new ObjectInputStream(in).readObject();
return rcvdMsgObj;
and the SecMessage Class is
public class SecMessage implements java.io.Serializable
{
private static final long serialVersionUID = 3940341617988134707L;
private String cmd;
//... nothing interesting here , just a bunch of fields , getter and setters
}

.
Actually, your client code is writing one object to the server and reading multiple objects from the server. And there is nothing on the server side that is writing the objects that the client is trying to read.
This exception may also occur if you are using Socket
s on one side and SSLSocket
s on the other. Consistency is important.
