COM - java difficulties

[ketil v]

I got to make Java use native methods written in a Delphi - program that I
dont got access to the sources for. The Delphi - programmers have made a
DLL for me to use as a interface, and a API telling me what's in the DLL.
I do not got the faintest idea about there to start digging for info about
how to do this, all I find is JNI - handbooks and examples about how to
write Java - programs that use specialized C / C++ / Delphi - classes, and
that both connect via a interface that got to be created specially.
This is not a option, since I dont got access to the Delphi sources, and
know nothing about Delphi, C og C++.

Does anybody know where I should look for a solution?

The environment is Windows.

There are a variety of Java-COM bridges out there. Most can take the
interface to a DLL and convert it into equivalent Java, generating the
necessary native stuff.

See

for some ideas.

I used a product called Linar's JIntegra.
It had good detailed instruction and I believe free download.

Thanks! - I'll take a look.

The importance of newsgroups can't be underestimated! - Have been struggling
with this problem over a week now, came almost to the point of learning
myself C, and refreshing my Pascal, to get around it...
