If I'm reading you post correctly, you want to be able to view these in NETSCAPE, right? Ok, two things. First, try upgrading to the full version of O2000, not the Beta. Also, go for the latest version of Netscape. I believe 4.51 had some issues with Java that got worked out in later releases.
Hope this helps (-:
