liveconnect and java console

Hello,

I try to get a communication between javascript and flash to work.
In the Macromedia TechNotes it says, that it should work under Mac OS 9 
and Netscape. But it doesn't. I downloaded the Netscape 7.0 version for 
the Mac.

Do I have to install a special Java plugin to get liveconnect to work?
I don't know if it is useful... but I cannot open the Java console in 
Netscape, only the Javascript Console opens and shows the javascript 
error messages for the function setvariable() that should normally send 
a variable to Flash.

Does anyone has a suggestion how I could fix this? Or can it be fixed 
somehow?
