I think the hardest part is convincing yourself that you can use one
or more core languages for your project. I guess we think we only
need C, or Java or C++ and that is it. But we normally integrate with
other technologies like JSPs anyway.
I have been programming with some JVM language since the early Jython
days and I still find it a little hard to break away completely from
using Java language code.
I want to integrate a Java, Clojure, Scala app but I still haven't
included Scala into the process yet.
