CNI & Exception handling

[RamrajPrabu Balasubramanian]

Hi,
      The project I'm working on involves writing CNI wrappers to existing 
c++ classes that we have. the problem is these c++ classes throw exceptions 
and there are a lot of them. I know catching c++ exceptions and rethrowing 
them as java exceptions casuses the " mixing java and c++ exceptions in same 
translation unit is not  allowed" error.
      Getting past this hurdle is very important for us to adopt gcj in our 
projects, can some one suggest some ways to handle these c++ exceptions 
without changing our existing c++ code ?

thanks,
Ramraj
