[vtkusers] Vtk+java+linux installation problem

[Lifang Liu]

Dear Mathieu,
      Thanks for your advice.  I have been log on root, so it should have 
right to access the files. The test was run under /usr/local/lib/VTK-build, 
I tried to run cone.java (using eclipse). It looks that the wrapper library 
could not be loaded normally.  Below is the error information:
     Exception in thread "main" java.lang.UnsatisfiedLinkError: 
/usr/local/lib/VTK-build/bin/libvtkCommonJava.so.4.5.0: libvtkCommon.so.4.5: 
cannot open shared object file: No such file or directory
	at java.lang.ClassLoader$NativeLibrary.load(Native Method)
	at java.lang.ClassLoader.loadLibrary0(ClassLoader.java:1751)
	at java.lang.ClassLoader.loadLibrary(ClassLoader.java:1676)
	at java.lang.Runtime.loadLibrary0(Runtime.java:822)
	at java.lang.System.loadLibrary(System.java:992)
	at Cone.<clinit>(Cone.java:17)

Clearly libvtkCommon.so.4.5 is generated and located under 
/usr/local/lib/VTK-build/bin

Any hint or advice would be highly appreciated!
