<TITLE>Problems with vtkCanvas and vtkRenderingJava.dll</TITLE>
</HEAD>
<BODY>
<P><FONT SIZE=2>Hello all,</FONT>
</P>
<P><FONT SIZE=2>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:</FONT></P>
<P><FONT SIZE=2>1) Added vtk.jar to the CLASSPATH and vtk/bin to the search path.</FONT>
</P>
<P><FONT SIZE=2>2) Added vtkPanel, vtkSettings and vtkTesting to the vtk.jar. These were obtained from the repository for VTK4.23.</FONT>
</P>
<P><FONT SIZE=2>3) Attempted to compile vtkCanvas so that I could add it to the jar file but received the following compile error:</FONT>
</P>
<P><FONT SIZE=2>C:\temp\VTKTest\src\vtkCanvas.java:7: cannot resolve symbol</FONT>
<BR><FONT SIZE=2>symbol : class vtkPanel</FONT>
<BR><FONT SIZE=2>location: class vtk.vtkCanvas</FONT>
<BR><FONT SIZE=2>public class vtkCanvas extends vtkPanel implements MouseListener, MouseMotionListener, KeyListener</FONT>
</P>
<P><FONT SIZE=2>3) Undaunted, I proceeded to compile sucessfully the SimpleVTK program, but when I attempted to run it I received the following run-time error:</FONT></P>
<P><FONT SIZE=2>Exception in thread "main" java.lang.UnsatisfiedLinkError: C:\Program Files\vtk4</FONT>
<BR><FONT SIZE=2>2\bin\vtkRenderingJava.dll: Can't find dependent libraries</FONT>

<BR><FONT SIZE=2> at SimpleVTK.main(SimpleVTK.java:49)</FONT>
</P>
<P><FONT SIZE=2>This error is listed in the archives but have found no indication of how to fix it.</FONT>
</P>
<P><FONT SIZE=2>Suggestions what to try next? Do I have to download the VTK source and rebuild it?</FONT>
