Thank you Russell,I am still in confusion.

Class files are enough to compile any program.I can see all classes in
my system.

what do you mean by 1.1,i did not get you here.

I have eclipse compiler to compile the code.

I have Firefox and internet explorer,Now tell me what to do to get the
code to compile .I will be clear in my statement. I imported the
corteai.zip into my project.In eclipse browser i can see all classes.

When i said "import vrml.node.*
import vrml.*" what ever.It is not showing any error.But
when i am extending the "Script" class.First of all it is not
recognising Script class
It is not at all recognising any class.
for Better understaning of the problem.The same code
"import vrml.node.Script" compiler is showing error that it could not
recognise Script.

where is plywood.jar,i could not find on my system!!!!.
Thanks in advance.

I meant the VRML plugin classes are written in Java 1.1
so it seems the compiler has to compile depreciated
classes or maybe I have just worked in deep matrix's source
code too long :)

Sorry, haven't worked with it yet. Only old M$ SDK
and Sun.

> I have Firefox and internet explorer

Cortona's VRML EAI, as far as I know, does not work with Firefox,
because Firefox uses Sun Java I believe. (But please,
prove me wrong! I will be grateful.)
It only works, again, as far as I know, with I.E. using the Micro
soft Java Virtual Machine (MS JVM) and the old Netscape 4* series.

Try adding the classpath of Cortona's JSAI archive:
C:\Program Files\Common Files\ParallelGraphics\Cortona\classes.zip
You should find it in there.

> where is plywood.jar,i could not find on my system!!!!
Probably wasn't installed because you don't have Netscape.
Sorry, thought it might be found in the Cortona program folder
anyway. If corteai.zip works for you, then don't worry about it.
