[vtkusers] Using VTK w/ Java - Can't get past VtkInit error

[Carlos Martinez]

Hi.

Sometimes I have got this exception. My problem was that the compilation 
version of libvtk*.so libraries wasn't the same as vtk.jar version. I mean 
that vtk.jar and libvtk*.so must pertain to the same build process. I 
don't know if this is a restriction, but I think that .java files 
generated have method signatures with numbers, that are not the same in 
all build processes.

You could erase the vtk.jar file (make a backup because I'm not sure) and
rebuild VTK. I think that the .class and .jar files will be compiled 
again. Then use this vtk.jar instead the older. Of course, you must set 
the CLASSPATH and LD_LIBRARY_PATH environment variables.

Tell us if this solves your problem.

Bye.
