Thanks for your clarification Tom. 
I tried deleting everything else except
/opt/visad-in-a-box and sourced it and did make
compile again. 
Still I got the errors. 

Think I should clarify on what I'm doing: 

I have three directories: 

1. /opt/visad-in-a-box which contains the .jar and the
extracted class files (without javax, I don't know
why); 
2. /usr/local/java3d-1_3_2-build4-linux-i586/ under
which I can see java3d media and javax class files; 
3. /usr/local/src/visad under which I have my source
visad files and also under which I ran the make
compile 
for compilation. 

In my CLASSPATH before I got your msg I put in all the
path links of 1. and 2. for compiling in 3. 

I guess I may have to copy over the subdirs in 1. and
2. under the root of 3. ??

Many Thanks!

Bst,
Victor
