Java with Fortran - possible with GCJ ?

[James Adams <james_adams at yahoo dot com>]

Hello,

I will soon begin work on converting pieces of an
atmospheric chemistry model, which is implemented in
Fortran, to an object-oriented design/implementation. 
The plan at this point is to use C++ for the OO
converted parts of the program since C++ classes can
be compiled into native object files and linked in
with the Fortran program.  However I am more familiar
with Java and would like to use Java as the
implementation language.

>From the brief description of GCJ that I've read it
looks like it may be a good alternative for me if I
want to use Java for the OO parts.  I hope so.

Has anyone done this sort of thing before, and if so
can you give some high-level pointers to someone who
is quite new to this sort of development ?  [My recent
experience has been solely with Java/JSP/JDBC and it
has been many years since I've had to deal with make
files, linking object files, etc. and I know no
Fortran.]

Is GCJ somewhat mature by now, i.e. are most of the
major kinks worked out by now to make it comparable to
the average C++ compiler in terms of ease of use,
performance of codes, etc. ?

Are there any IDE's which can use GCE, or perhaps a
better question, how would I integrate GCE with an IDE
such as Visual Age, XEmacs/JDE or Rational's XDE ?

I will really appreciate any feedback.  Thanks in
advance.


-James
