Creating DLLs with Java
Hello all,
I am working with a suite of products, trying to
interconnect their functionallity. One of the products that
I am tying into works well with DLLs. Is there a way that
I can create DLLs using Java? I am not really interested
in creating Java functionallity...then C/C++ placeholders
...then tying both the Java and the application into the
relatively empty placeholders. Is there a way to get a
"direct" connection? Thanks.

Re: Creating DLLs with Java
Right...remind me not to ask yes/no questions in the future...too unsatisfying.

Re: Creating DLLs with Java
Okay, sorry to give the short answer. I assumed you didn't mean you wanted
to write a compiler in Java that would output DLLs -- although you could do
that. I assumed you were asking whether you could create a DLL whose entry
points were methods of a Java class, or something along that line. There's
a tutorial on Sun's Java site on how to use JNI (start at
http://java.sun.com/docs/books/tutorial/trailmap.html), from which it's
apparent to me that the parameter lists for Java differ from the ordinary
parameter lists someone would have used in writing a DLL. So some kind of
adapter code would be necessary, and that's JNI. But you say you don't want
to do that. I don't blame you at all, after following the tutorial. I
don't want to do it either, and I have a DLL that I'd like to call from Java
too. I'm going to write a program that takes a list of arguments from the
command line and calls the DLL, then I can call that program from
getRuntime().exec().
