[vtkusers] Problems with vtkCanvas and vtkRenderingJava.dll

[Shyam Prakash]

David,
            Have you compiled vtkPanel.java with -d option. If not try
as given below
 
            javac -d . vtkPanel.java
            
            This will create the directory "vtk" in the present
directory. Under vtk directory you will have vtkPanel.class. 
            Now add the complete directory to vtk.jar as
 
            jar -uvf vtk.jar vtk           /vtk is the directory I
mentioned above
            
            This should take care of your issue #3.
 
            It looks like jawt.dll is not in the system path. jawt.dll
can be found at
 
            <JAVA_INSTALL_DIR>/jre/bin
            append this path to your system path and should be ready to
run your vtk programs.

Subject: [vtkusers] Problems with vtkCanvas and vtkRenderingJava.dll
 
Hello all, 
I am currently evaluating use of VTK in a research group but have
encountered a problem running any VTK code under Java 1.4. First, I have
only installed the Windows binaries on my Window 2000 workstation and
have not yet attemped rebuilding them from source code. The following
steps were completed:
1) Added vtk.jar to the CLASSPATH and vtk/bin to the search path. 
2) Added vtkPanel, vtkSettings and vtkTesting to the vtk.jar. These were
obtained from the repository for VTK4.23. 
3) Attempted to compile vtkCanvas so that I could add it to the jar file
but received the following compile error: 
C:\temp\VTKTest\src\vtkCanvas.java:7: cannot resolve symbol 
symbol  : class vtkPanel 
location: class vtk.vtkCanvas 
public class vtkCanvas extends vtkPanel implements MouseListener,
MouseMotionListener, KeyListener 
3) Undaunted, I proceeded to compile sucessfully the SimpleVTK program,
but when I attempted to run it I received the following run-time error:
Exception in thread "main" java.lang.UnsatisfiedLinkError: C:\Program
Files\vtk4 
2\bin\vtkRenderingJava.dll: Can't find dependent libraries 
        at java.lang.ClassLoader$NativeLibrary.load(Native Method) 
        at java.lang.ClassLoader.loadLibrary0(ClassLoader.java:1473) 
        at java.lang.ClassLoader.loadLibrary(ClassLoader.java:1397) 
        at java.lang.Runtime.loadLibrary0(Runtime.java:788) 
        at java.lang.System.loadLibrary(System.java:832) 
        at vtkPanel.<clinit>(vtkPanel.java:27) 
        at SimpleVTK.<init>(SimpleVTK.java:19) 
        at SimpleVTK.main(SimpleVTK.java:49) 
This error is listed in the archives but have found no indication of how
to fix it. 
Suggestions what to try next? Do I have to download the VTK source and
rebuild it?
