[vtkusers] VTK with JDK1.3.1_08

[R K Shyamprakash]

Jeff,
      I am running the application on Windows NT. I will test the same on
Windows 2000 and check if it works.
	One more thing. vtkPanel occasionally crashes(may be once in 150 times or
so) in the Render() method. Below is the exact location where crash occurs
  public synchronized void Render()
  {
    if (!rendering)
      {
        rendering = true;
        if (ren.VisibleActorCount() == 0) {rendering = false; return;}
        if (rw != null)
          {
            if (windowset == 0)
              {
                // set the window id and the active camera
                cam = ren.GetActiveCamera();//here the application crashes

	Is it because VTK is unable to find the active camera associated with
vtkRenderer? Have you come across the same problem? below is the error
message


An unexpected exception has been detected in native code outside the VM.
Unexpected Signal : EXCEPTION_ACCESS_VIOLATION occurred at PC=0x24807FCD

on which os are you compiling?  I have seen this before on winnt and
older versions of java.  vtkPanel/Canvas are only dependent on jdk1.3 or
greater.  I think it is a winnt/jdk1.3 problem.
