[vtkusers] [EXTERNAL] problems running a vtk java bindings example

[Gerrick Bivins]

Hi Henry,
It looks like you are trying to reference the jar that has the natives in them.
Last time I tried,unless you have some special handling code to extract 
the natives for your platform from that vtk-6.1-natives-Linux-x86_64.jar,
I don't think you'll not be able to load the native dll's/so's at runtime.
Vtk just isn't setup to do that for us.

Currently, to run with java you need to extract those dll's/so's to some directory
and then set your PATH/LD_LIBRARY_PATH etc to point to the directory and
then run.
I think you can also set some command line arg that will tell vtkNativeLibraries
where to load them from.

Subject: [EXTERNAL] [vtkusers] problems running a vtk java bindings example

Hello guys, I have set up and compiled VTK through cmake on a 64-bits Ubuntu 14.04, just to get VTK Java bindings, but I have failed to run a simple "Cone.java" example. Specifically, when I try to execute the
statement:

System.loadLibrary("vtkCommonJava");

The compiler throws the following error: 

Exception in thread "main" java.lang.UnsatisfiedLinkError: no vtkCommonJava in java.library.path
	at java.lang.ClassLoader.loadLibrary(ClassLoader.java:1886)
	at java.lang.Runtime.loadLibrary0(Runtime.java:849)
	at java.lang.System.loadLibrary(System.java:1088)
	at Cone.<clinit>(Cone.java:17)

--------------------------------------
To specify what my problem is, please, read these comments:

1- The VTK compilation process produced the following .jar files (both placed at /usr/local/ directory):
	vtk-6.1.jar 
	vtk-6.1-natives-Linux-x86_64.jar

2- The library files "vtkCommonJava.o" is not among those produced by the compilation process.
3- The most similar library file to "vtkCommonJava" that I have found is "libvtkCommonCoreJava.o", packed into the jar file "vtk-6.1-natives-Linux-x86_64.jar". I have included this file into the "Java Build Path" of my Eclipse IDE, as well as the jar file "vtk-6.1.jar", but still the program fails to run.

I will appreciate any suggestions on what is missing here to run the java example. Thanks in advance.

Henry
