Read operation failed from Socket.

We had a legacy application built on IBM RAD tech stack which has Socket Server and client ( Client is a third party application)
Server was using BufferedReader and BufferedWriter to read and write data from sockets in IBM-1025 Char set.

Now i am re writing the same server in Java6

As part of application specific protocol....

After the successful connection client should send a time stamp in str format to start the communication.

Here ... the new server is failing to read the data and is on hold for some time @ read statement before Connection times out.
Here i used diff alternates to get this worked.
But could not able to succeed.


So thought of asking help to figure out ..

I'm assuming that you're using the method BufferedReader.readLine(). That method reads a line from the buffer. A line is terminated either by a line feed, carriage return or both. So if the client doesn't send a line terminator then the method will block and wait until one is send.

I am not using readLine method...

I am using read method

private String receiveMessage(int pBytesToRead)
throws SocketTimeoutException, IOException
String methodName = "String receiveMessage(int pBytesToRead)";
char charArray[] = new char[pBytesToRead];, START_POS, pBytesToRead);

_logger.logp(Level.FINEST, CLAZZ_NAME, methodName,
"Read : " + new String(charArray));
return new String(charArray);
I agree. Here's the link:

It's not a secret anymore!
