Thanks for the post. very informative. It is reassuring to see that somebody
is using Java and Vtk together successfully.

The short answer is that I'm still having the problem.

The import GuiCommon.*; was the result of a cut and paste. It does not do
anything in this example.

I've now got to the stage where it does not matter whether I include the 
System.loadLibrary("Xt") - it now SEGVs all the time. I had forgotten to use
the configure --with-x option.

I'm now now linking libvtkJava with arguments similar to yours. The only
difference is that I'm not including the Contrib and Patented libraries and
using MesaGL instead of GL. The latter must be the problem so I'll reinstall 
it.

Cheers
