Okay at this point I'm just testing the client side code. Every page will
display 100 Jms Messages and as we paginate through it will show the next 100.
I can do some optimizations but wanted your input on the design of it. Changed
a bit of the UI to look more modern using bootstrap and jQuery.
See screenshoot:

This was done by utilizing Bootstrap 3.0 css + jQuery + teamwork to get RSS
feed data from the ActiveMQ for the first 100 in the queue. As we go deeper the
slower it will be. Appreciate any feedback I'll be online at the usual times.
I'll send in my pull request once I'm satisfied that everything is working 100%
test and fully functional.
Best Regards,
Zak

> when trying to browse that queue.
> To reproduce it:
> 1. Start a broker with default configuration
> 2. Send 200k messages with
> {code}ant producer -Dmax=200000 -Ddurable=true -Dsubject=TEST{code}
> 3. Try to browse the queue
> http://localhost:8161/admin/browse.jsp?JMSDestination=TEST
> The proper solution to this problem is to implement proper pagination while
> browsing the messages, so users can browse through all messages showing 100
> msgs (or so) at the time and not using all the available memory.
