[vtkusers] vtk java compilation error: "cannot find symbol: class vtkCamera"

[Eric E. Monson]

Hello,

Those instructions are a little old -- I think the vtk.jar file really  
should be built automatically when you build VTK as long as you have  
turned the VTK_WRAP_JAVA to ON in ccmake.

Did VTK seem to build okay? If so, did you check in the ./bin  
directory and see if vtk.jar was generated?

(There are more detailed instructions for building VTK are in the  
README.html file in the root directory of the source code you  
downloaded, although there is not a lot specific to the Java wrappers.)
