Hello,
definetly, classloaders RCPs and dynamic libraries are terms that had
"owned me" for a long time. In my last project I left it as impossible (I
had a secundary nasty way to accomplish my objectives...), but now I
can't, now I must face it.
First of all, let's say that I'm "trying to run" a RCP with the
OpenGL-Java's API LWJGL. I perform the following steps:
1) Create new plugin-project, make it RCP, use a template example view.
2) In the project root directory, I create a lib/ and a jar/ directories
where I put LWJGL dynamic libraries and jars respectively.
3) In plugin.xml Runtime tab, I configure the classpath to include all
jars in /jar dir.
4) Make a product
5) Write Java code, for example, create the canvas inside the view.
6) I especify to vm where to find the libraries in run configuration:
-Djava.library.path=lib/ in arguments tab, vm box.
7) click on run
8) The Rcp is created, but it can't find the lwjgl in classpath lol.
That's the error: "java.lang.UnsatisfiedLinkError: no lwjgl in
java.library.path" .
With the same configuration as the above one, if I create a main method in
one class and I configure a "run as a SWT aplication" instead than a
"eclipse aplication", it works perferctly.
I hope somebody could explain this strange behaviour.
Thanks,
Víctor Llorens

To work in an RCP app you need to:
1) create a plugin for the jars
2) include the native libs in the plugin
3) use Bundle-NativeCode to specify the native libs
Then the jars and native libs will be available for your RCP application.
