C++ accessing GCJ

[Scott Serr]

We've been diving into GCJ for about a week.  We would like to do the 
majority of a project in Java but allow others to have hooks into it 
with C++ and TCL.

I have two questions.

1. When accessing a Java class from C++, why is there Jv* setup and 
tear-down?  Seems like when you have that Java class in a .so... it 
would be indistguishable from an .so generated from C/C++. 

2. I'm very new to TCL, but I've found it's ability to script C/C++ 
functions/classes is pretty transparent.  TCL seems to be able to get 
ahold of C/C++ data structures quite easily.  We have basically proven 
that TCL can access a small C++ wrapper that accesses a Java .so.  Is 
there anyone out there doing this?  Is there any slickness we can use to 
see a Java/GCJ object from TCL?

Any help is appreciated.

Thanks,
Scott Serr
