GTP prime library for Java (3GPP 32.295)

Recently I needed to have a client application for a GTP' external system. I did some research on the web but unfortunately did not find anything usable for me (found one java library on kenai.com but the implementation is in very early phase, the other was open-cgf written in Erlang for which I found two obstacles the language + crash dumps when it was starting up on my Ubuntu Natty 64-bit box). Having some development background from the past and having a look on the 3GPP 32.295 specification I decided that it is not a big amount of effort to implement it. I think this is a good opportunity to learn the protocol and additionally check the JBoss Netty framework - which seems to be a perfect match for such a solution. Indeed writing a client/server application using JBoss Netty is pretty straightforward (I will try to provide more details in another article) - it mainly about writing proper encoder/decoder and handlers.

The outcome can be found in the google code under the link: http://code.google.com/p/gtpprime/.
