Hi Powerbuilder guru.
I open a post in the hope that it will not go off topic.

In the company we are trying to write a DLL that must be read by PB and Java.
Abandoned the 'NET Assembly target' we wrote this DLL with Visual Studio c #.

Assuming that in Powerbuilder I have to invoke the DLL as an ole object, how should I do it in Java?

CAN YOU HELP ME ?

The technicians tell me:
 1. * _Javonet_ * (https://www.javonet.com)
    It is a library that is used easily and quickly, but it is very expensive.

 2. * _Jni4net_ * (http://jni4net.com) -
    It does the same things as Javonet.
It's free, but development / support ended in 2016.
 
What alternatives could we have?
(naturally we would not like a _ * native wrapper * _
(Java calls a dll in C ++ that calls the dll in c #).

Every suggestion is welcome
Gimmy

I don't know what your Jave code does, but which database are your running?

I know that Oracle for example allows you to run Java code from stored procedures.

Though not a DLL, could that be a solution?

You might look at the ikvmstub utiltity that is part of the ikvm project:

https://sourceforge.net/p/ikvm/wiki/Ikvmstub/

It creates stubs for java for .Net assemblies.

I've used IKVM, but not that particular tool.  I was using the main ikvm project for compiling java code into .net assemblies.

Create a web service that exposes the methods of your DLL. From Java and from Power Builder call the methods of the web service.

Sincerely,

You are right, but WS is to slow for our project.
