Unless you're unbelievably lucky in the format that the existing functions
use, you'll have to write a "bridge" DLL.  I just did a project that needed
to call CPI-C functions from a purchased DLL (CPIC.DLL) in Java.  I had to
create a "bridge" DLL called (JNICPIC.DLL) that could be invoked by Java and
would then massage the Java passed parameters (Jstring to C string, etc.)
before invoking the "real" function from CPIC.DLL....lbt
