Re: java library

I don't know how much work is involved in setting up and maintaining a sourceforge CVS but perhaps QuantLib could start a Java version.  I would be more than happy to contribute.  I had a stab at converting parts of Quantlib to Java just to do some comparisons in coding and design.  To do the whole library would be huge amounts of work but with a combined effort maybe it would speed along.

Even if it never took off or got completed it would raise some interesting design debates.

Michael,
         I don't want to start a language war here: I had a go at half a
dozen languages myself (including Java) and each of them had features which
were nicer than all the others, and features which were not.

The two main reasons we chose C++ were a) we had more expertise in the
latter and b) most scripting languages can be interfaced with C/C++ (e.g.,
we currently export QuantLib to Python and Ruby, and work is being done on
Scheme as well) but not with Java.

As for your library, I think it is quite interesting. We won't be able to
exchange code, but we can still compare designs. What do you think?

Bye,
         Luigi
