Hello! I have a Java application, which has a lot of GUI and one complex algorithm. I spent many months writing and debugging that algorithm, but it still has a lot of bugs. At the moment, I am thinking about implementing that algorithm in Haskell, while leaving the GUI in Java. I would like to know whether it is possible to write algorithmic (let's call them back-end) parts of a system in Haskell and user interface in Java? Can Haskell and Java parts of a system co-operate? Will such a hybrid system run on Windows and Linux? Are there any tutorials about this? Has someone already tried it? Thanks in advance Dmitri Pissarenko
