[vtkusers] Newbie Java question (yet another)

[Johnson, G (Greg)]

Hmm.  I guessed that maybe vtkPanel should be in vtk.jar and wasn't so I
stuffed it in and BINGO it compiles.  However, I get a new error when trying
to run the code:

D:\Program\vtk31\java>java sphere
Exception in thread "main" java.lang.UnsatisfiedLinkError: VTKInit
        at vtk.vtkObject.<init>(vtkObject.java:77)
        at sphere.<init>(sphere.java:28)
        at sphere.main(sphere.java:86)

I am guessing that VTKInit is a startup routine in the vtkJava.dll - right?
Any clues on how to fix this one?

Cheers,
greg

Hi folks, 
  Though I've trawled the archives, I can't seem to find anyone who has had
this problem (or at least needed help sorting it out).  I am trying to get
the Java interface working under NT4, and though I can compile and run the
Test.java code, compiling the sphere.java test doesn't work.  I get the
following errors:

sphere.java:28: Class vtk.vtkPanel not found in type declaration.
        vtk.vtkPanel renPanel = new vtk.vtkPanel();
           ^
sphere.java:28: Class vtk.vtkPanel not found in type declaration.
        vtk.vtkPanel renPanel = new vtk.vtkPanel();
                                       ^
2 errors

I have tried compiling vtkPanel and vtkPanel.class is in the same directory
as sphere.java, and my classpath points to the current directory as well as
vtk.jar and classes.zip.  This vtkPanel was in vtk31/java but there appears
to be another vtkPanel in vtk31/vtk31/java/vtk alongside a
vtkPanelBeans.java  (I do not understand the directory tree at all).  The
only difference I can see between them is comments around the three
Windows/X11 display lines.  But what is the PanelBeans for?  

Any tips would be much appreciated!

Confusedly,

greg
