Hi Richard,
I am hoping to hear that someone is able to use the swig bindings for something non-trivial in java which is clearly more than you or I have (yet!) managed. I want to see some code that actually works as I'm skeptical that the bindings are functional for java.
Luigi's response to you seems correct for the case where one wants to access functionality which hasn't yet been mapped in the swig bindings. My issue is instead one where the swig bindings are defined but they just don't seem to work. I agree that writing my own JNI stuff wouldn't be fun, but I wouldn't try to map the entire api, just specific questions I might want answered, e.g., the price of an option on a future. This is a much more constrained issue which isn't so difficult much as I'd prefer to avoid it if the swig stuff can be made to work...
All of that said, if you have a concrete idea about how we can work together, I'm glad to hear it. For
now, it seems a starting point is to get something simple, like what I'd provided, to work. I hope someone will be able to point us in the direction of a working example. (Pretty please! :-)
Regards,
Tito.
ps - I've moved this from the dev to the users list as it seems the more appropriate forum

Hi Tito,
I have a lot of code in Java as well and I'd like to plug QuantLib in.
It's incredible how you and me are facing the same problems, following
the same path and started translating the same example! :D When I
looked at you Java code it was quite similar to mine (of course... you
also translated the example in C++).
Oh well...
I dont think that writing your own JNI is a good idea.
It's a huge,
boring and error prone task. I'd rely on SWIG instead.
It'd be much easier to learn how to hack the intrincacies of SWIG.
It would be great if we were able to convert comments from C++ code to
JavaDOC as well, as Eclipse would be able to show documentation as you type.
Another thing to be considered is performance.
I tried to use Matrix and it does not make sense to initialize every
cell at a time. The performance will be poor. It means that we should
create additional methods intended to be called by another languages due
to poor performance of separated calls.
I've posted one thread quite similiar to yours and Luigi gave me some
directions. In case, I've use Matrix as an example of issues I've found.
I'm planning to work on SWIG this weekend. Maybe we could work together
on this kind of thing.
Kind Regards
