Java Programming

Hi,

I'm in current need of developing an application to send and receive data, to and from a third party app.

For this, I need to create my one TCP/IP blocks, because there's already a communication protocol that tells me how this tcp/ip blocks should be formated (size and binary data).

I need a few tips to get started with this, like for example, will using the java API support for sockets be suffice to accomplish this, or do I need to program with raw sockets, in which case, i'm not sure if the java api has suport for low level socket programing..

Any help you can give me will be much apreciated.

Thanks in advance.
