Seperating Network Packets

Question

Hello guys.
I am attempting to make a proxy which simply relays information received to where ever the proxy is set to relay to.
At the moment, I simply have a while loop reading the inputstream into the outputstream.
However, I would also like to display that data that is being transfered. At the moment I am simply adding all data to a text area, but as you can imagine that would get cluttered fast.
Is there a way that allows you to determine the start and the end of a TCP/IP packet? This way I would be able to separate data in the transfer text areas into their own packets, and it would be much easier to read.
Any ideas?
Thanks in advanced!

A tcp socket does not know the notion of the message boundaries. The sending side writes the data as a stream of bytes and the receiving side obtains them in potentitally different chunks.
But you can pick an appropriate buffer length, and read the data in chunks:
while((r=in.read(buffer,0,buffer.length)) != 0) {
}
