You can send any XML object the IP phones understand via CiscoTerminal.sendData, including image objects. I am actually sending CIP images inside a CiscoIPPhoneStatus object via sendData and that works like a charm (although one time I had to reboot the whole cluster because I couldn't push anything to any phone anymore).
Of course, HTTP Post is also an option, regardless of the programming language. And you generally do post via a socket from a programming language, but modern APIs offer direct means of making a http connection, making your job a bit easier (like you create a httpconnection object to the IP phone, set the authentication header, then send the CiscoIPPhone xml object).
The advantage of JTAPI is that you have no authentication, and from what I have heard and experienced, JTAPI seems somewhat more stable.. probably because Cisco uses it in their own applications (IPCC Express mostly, and IVR/Unity Express). The disadvantage is the additional configuration on the call manager (controlling user).
The advantage of HTTP POST is that it's lightweight, but you have the authentication thing which causes load on the ccm (so for large scale pushes you should set a custom authentication url that handles the authentication and not always connects to the ccm) and as I said above, it seems somewhat less reliable.

The short answer is that you don't.... That isn't entirely true while at
the same time it kind of is, but for the most part you don't configure
the softkeys. You enable or disable them via TCL. Here is the long
