TcpJavaGateway, can anybody give me information about the IBM CTG package?

Hi, I have been given an application to debug. I am not sure what this class (TcpJavaGateway) does but the error is related to it. I would like to know what purpose to the CTG package to us?

I know it is some kind of transaction gateway to connect to a a database but I am interested in why do we need it? Why not use a jdbc connection or something.

Also if you can tell me more about the error it would be great! Thanks.
