Java 3D not working

[Daunlessk]

Hello. I'm making a program that uses java 3D timer and have tried installing java 3d but it does not work. I have downloaded the Windows 64 bit executable from the java website, it seems to install correctly but then I get the same error when trying to run the program:

Exception in thread "main" java.lang.Error: Unresolved compilation problems:
The import com.sun.j3d cannot be resolved

Do I need to do something with the environment variables? Does it have something to do with eclipse? I haven't found much information anywhere for explaining how to get it installed properly.

any help?

Any help here? I don't really understand what I'd need to do in environmental variables. I'm not sure why simply running the exe installer for java 3d didn't work...
