Java HotSpot Virtual Machine

Hi all

We are planning to use a library(written in fortran) for a particular data format (all binary).we also have the "C Wrappers" around the fortran code.We cannot re-write the whole thing in java since it was written around 20 yrs back and we don't have any knowledge of fortran,also it takes lot of man power to learn and understand and then re-implement it.So we are looking for a automatic JNI code generator for these C wrappers.
I found that there's one called SWIG but user recommendation was less for it.so do we have any other tools available??


thanks
