Hi Arvind;

I notice that you are putting your vtk class files in
/usr/local/src/vtk/Java_Classes/vtk. I suspect that your CLASSPATH variable is
set to this directory as well and there is a bunch of *.java there. Is it
possible that you are updating Vtk from a previous revision? If so this could
be the problem. You need to ensure that you CLASSPATH points only to Vtk rev 
3.2 *.java files.

In my case I am compiling the library in ~/software/Libraries/vtk3.2 and my
class files will end up in /usr/local/vtk/java/ (in package vtk). So, in my
user.make JAVA_CLASS_HOME=/usr/local/vtk/java. Normally my
CLASSPATH=/usr/local/vtk/java which previously contained my Vtk rev 3.1.2
*.class and *.java files. But berfore I make rev 3.2 in
~/software/Libraries/vtk3.2 I must unset CLASSPATH and then
export CLASSPATH=~/software/Libraries/vtk3.2/java so that there is no
contamination between the two revs.

Hope this helps.

Cheers
