I can publish to safari but when I enter the url into ical and enter the user and password it will not subscribe. I get the triangle and the do you wan to go offline/online error. Even the read only individual calendars do not work.
I went from the plugin which worked great to the servlet which now does not work. Switching back to the plugin gave me the same error. I am back trying to figure this out on the servlet. Please help!

I re-started the server and that seemed to fix the problem. Not sure what the fix was but all is good now.

Thanks for the feedback!
