Re: Passing Interfaces from COM to Java

Read about CreateStdDispatch in MSDN. With this function you can convert C++ class pointer to IDispatch reference (with some restrictions).

That's a pity actually, because with each day of separate development
it's becoming more and more complex to integrate back. Remember
GNU/Emacs vs. XEmacs story?

The same with me, actually. One reason that I try to use Java is
that:
1. It's de-facto standard in the SemanticWeb scientific community
2. There's a lot of code developed in Java I'd like to use
3. Writing COM in C++ is pretty boring, because on each line of
useful code I have to add the check of return code and logics what to
do, what to free on different return codes. That's a huge pain!

Still you didn't answer my question:
What C++ code to write, and what Java code to write to pass a
reference to IDispatch-compatible interface from C++ code to Java
code?

NJawin is nice, but it doesn't make me any closer to my task than
Jawin ;-(( or at least I'm too stupid to understand how ;-))

Sincere,
Maxym
