Using css tabs to change just the text

Here is what I am thinking. I have a page which right now list links to control various parts of an environment, actually two environments, Weblogic, iPlanet, a custom java management page.

Showing all the links on one page is a bit much, so I wanted to use tabs for the two environments.

I can figure out how with 3 pages but I am wondering if this can be done with one. I just need to up date an unordered list from one environment to another. Any ideas?
