Google App Engine/C#/Java question.

[bluestarultor]

Well, I've jumped the gun in my excitement to get my main game project off the ground and have a start on it in C#. Ideally, I'd be able to continue to write it in that because it's what I'm most comfortable with. On the other hand, Google App Engine doesn't use C#. Just Python and Java, and since I don't know Python, I know where I stand in that decision.

The question is whether a C# program can call out to Java functions on the server somehow. Is it possible to do it directly? Could I use the script I've created as an intermediate? Will I just have to deal with Java's lack of unsigned types and hope it can handle my graphics? Can Java even palette swap an image with transparency yet, or is there some way to assign a transparency key that in turn isn't going to burn through the interface? Will I have to try some sort of RLE?
