Heya
I wanted to ask if there is a possibility to read/write to a socket, that is used by another application (on the same computer). Basically I want to manipulate its datastream (drop/replace/react to specific packets). Could you help me getting started? Thanks in advance for any help.

Reading the packets is one thing (and not a very Java thing either but let's just put that aside for now). But you want to manipulate them mid course? This doesn't seem like it will be possible or practical. You can't just make changes willy nilly to a stream of data. The other end is probably expecting a certain format etc and the changes you will make seem more than likely to disrupt that format.
I think you need a better and more realistic approach to solve your problem.
It's not like I don't know the data format of the application. I have enough knowledge when it comes to networking. It's also possible, because there are programs out there (packet sniffer) that can use an open socket and send packets using it. My problem is, that I have no idea how to implement the whole thing in Java.
First i don't know the way irc works. The solution i give is for grogram X that use tcp/ip(or udp) to connect to server Y on port Z.
So we create program P that listen on port Z on localhost and connect to port Z on host Y. Then we connect program X to program P on port Z on localhost. Program P listen the content that program X send and send them(with or without correction) to server Y. When server Y respond the program P sends the answer to program X. So for program X there is no matter that it's not connected directly to Y.
This dosen't work if it use ssl or something like it.
