[vtkusers] java Exception with vtk

[Eric E. Monson]

Hello,

Does the same thing happen when you try to compile and run the  
simplest java examples that come with VTK? Try Cone.java in VTK/ 
Examples/Tutorial/Step1/Java and see what happens.

At least for these simple apps, I don't need to do any copying of  
files, I just need to set the CLASSPATH and JAVA_LIBRARY_PATH  
environment variables as I stated below. Note, though, that I'm using  
the Java 1.5 that ships with OS X 10.5, and I've built VTK using the  
MacOSX10.4.sdk, in case that makes a difference.

-Eric
