Your answers makes me more curious. Ok, now what I know is we have
"Core banking  Engine" and gazillion surrounding systems such as
front-end, back-end, etc. So, what's going on that Core stuff? which
technologies are used? (maybe ORACLE's). is that a mainframe? or just
a distributed system?

Another questions: What about E-Banking? It seems it's a subset of
whole banking system. then which JEE technologies  are employed in
E-Banking?

Let me be clear, I'd like to know which special capabilities (as a
java developer) are needed to work for companies like Kishware?
