[vtkusers] What could the possible problem be?

[Jeff Lee]

Hi Jason,
The native methods get mangled in a certain way so that java can find 
them  The method is defined in libvtkCommonJava.so as 
Java_vtkPanel_SetSizeInternal(...) (see vtkJavaAwt.h).  Because you put 
vtkPanel into a package, java is looking for somtehing like 
Java_vtk_vtkPanel_SetSizeInternal(...).  You can see exactly which 
method java is looking for if you type 'javah -jni vtkPanel'.  Because 
of the way vtk is built, you cannot put vtkPanel into a package.  Take 
the package declaration out of vtkPanel and change your other code to 
look for vtkPanel, not vtk.vtkPanel.  Of course, vtkPanel needs to be 
somewhere in your CLASSPATH...
