BufferedInputStream problem in Sockets in Java

schlaps

I written a client and Server program. However Messages are not being recieved 10% of the time by the Server and the client says it sends them. Neither client or Server throw exceptions. and the server seems to be blocking on read as normal.

What i have done iswritten my own class that extends the BufferedInputStream class to allow an array of bytes to be read, and will block until all the array is collected.

/**
* Reads next bytes into an array of bytes. It blocks until all requested
* bytes are read. s is the socket.
*
* @param b the buffer into which the data is read.
* @param off the start offset of the data in b.
* @param len the number of bytes to read.
*
* @return the number of bytes read.
*
* @exception IOException if an I/O error occurs or if the end connection has been closed.
*/
private int read(byte b[], int off, int len) throws IOException {
int r = 0;
int p = 0;

while (p < len) {
r = super.read(b, p+off, len-p);

System.out.println("got -> " + b);
if (r == -1) {
if (s != null) {
s.setSoTimeout(0);
}
throw new IOException("end of stream reached");
}
p += r;
// Change to socket timeout after the first bytes are read
if (s != null) {
s.setSoTimeout(10000);
}
}
if (s != null) {
s.setSoTimeout(0);
}
return len;
}

(Sorry if the indentation is out)

However when entend FilterInputStream, instead of BufferedInputStream, all messages are recieved.

Can anyone explain what is going on?
