Can't load library: ...natives\windows-i586\\gluegen-rt.dll

Hello,
I'm trying to change Java3d in my project from 1.5.2 to "1.6.0-pre12-daily-experimental daily"
When I add the necessary libraries (4 jar files) to my plugin-project, I get the Exception:
     - java.lang.UnsatisfiedLinkError: Can't load library: C:\Z_Work\Programme\eclipseMarsJee32\natives\windows-i586\\gluegen-rt.dll.

When I unzip the jar file and save all native DLLs in an internal folder in my prolect, then make so me changes in the MANIFEST.MF file corresponding to native dlls, I receive the Exception:
    java.lang.NoClassDefFoundError: Could not initialize class javax.media.j3d.VirtualUniverse
          at javax.media.j3d.GraphicsConfigTemplate3D.getBestConfiguration(GraphicsConfigTemplate3D.java:317)

What do I wrong?

When I create a new non plugin project and integrate the all necessary jar files, it works well.

Hi

What do you mean by "plugin project"? Do you use OSGI?

Can you give the full stack traces? It's hard to tell what's going on.

However your unzipping of the dll's looks like it hasn't worked

VirtualUniverse has a static initializer that calls MasterControl.loadLibraries

MasterControl.loadLibraries constructs the Pipelien which in turn calls Jogl setup code.

So the line
 java.lang.NoClassDefFoundError: Could not initialize class javax.media.j3d.VirtualUniverse

Probably just means it still can't find your native libs.

More information on your setup will allow us to replicate it and give you advice.
