I don't think you can access your exposed JSF bean with ${Database}. I think you have to dig deeper in your context if you use ${}

What you CAN use is #{Database}, ofcourse that isn't compatible with the c:forEach tag, but it's what you have the h:datatable tag for.

That indeed looks better. Now, what you're facing is probably your temporaryMehod that is not being called, so your list doesn't get values.

Try just giving it some values in the bean constructor to start with, so you know your jsp is allright. From then on, try building your navigation structure because yours doesn't make much sense to me...

Good luck.
