This is tricky, most application virtualization/streaming solutions can't package and stream IE itself so it depends on how it interacts with the Java machine whether or not you can isolate it. Can you describe more details of what you need? You probably could execute IE in isolation and virtualize the registry keys and file links you need different for various Java engines..
