JNI in RCP [message #465604]

Hi,

I have a problem with loading some DLL files in my RCP application.

My RCP application contains several different plugins. One of them uses JNI
and depends on several DLL files. When I run the product from Eclipse IDE
everything works fine with modifying the java.library.path-value in the
launch configuration and adding the dll files to the PATH variable in the
project properties.

But when I export my product I get several problems:

- How to add the java.library.path-value to the config.ini without needing
the absolute path of the DLL location???

- How to add the path of the DLL location to System-variable PATH without
having to start Eclipse via a .bat file???

Please excuse my fragmentary knowledge of JNI, my task is to combine the RCP
application with the classes using JNI.

Thanks in advance!

Greetz,
Carsten

Hello Carsten !
please read this article http://www.eclipsezone.com/articles/eclipse-vms/?source=arch ives
which hopefully helps you.
A good starting point is to put the *.dll in the top level container of your plugin or plugins.

NB Also make sure you load the DLLs in the right order. If A->B then you must load B first, then A. I'm sure you'll know the right order; but if not, you can always try the various combinations until you get it right :-)
