[Swig-user] translating C++ exceptions to Java exceptions that extend java.lang.Exception

[Michael H. <mic...@gm...>]

Hello, I'm new to SWIG and I've been playing with the examples in the
documentation, but I've been having some problem with exceptions.  I want to
translate my C++ exception to a custom checked Java exception.  I've
followed the example in the documentation, but I can't get FileException to
extend java.lang.Exception.  I have everything in the .i file.  I'm using
swig version 2.0.1 (the latest).  Here's my interface file:

/*Example.i*/
%module example
%include "std_string.i"
#include <string>

class SimpleFile {
        std::string filename;
public:
        SimpleFile(const std::string& filename) : filename(filename) {}
        void open() throw(FileException) {
               std::cout << "Something bad can happen..." << std::endl;
        }
};

class FileException {
        std::string message;
public:
        FileException(const std::string& msg) : message(msg) {}
        std::string what() {
                return message;
        }
};

%typemap(javabase) FileException "java.lang.Exception";
%typemap(javacode) FileException %{
        public String getMessage() {
                return what();
        }
%}

How can I get FileException to extend java.lang.Exception?  Thank you very
much!
