Transporting Transports

Hi, i have a dev enviroment where all my dev work is done, once its completed i want to transfer everything, i.e. all the modules modifed to my test enviroment. How do i go about do that? i was hoping to be able to control this through a JAVA api, is there a functional module that will move the transport for me? or will TP.exe do that for me?

Any examples wil be greatly appricated.

Thanks - Peter
