These pages were written as slides for a presentation at work. Sometimes I have added extra notes/comments below the main area. You can jump here using the "Footnotes" link at the top left of the page.
Thanks to the people on various mail lists, and the implementors of Mule and ActiveMQ for all their help. I am new to all this, so despite that help I probably still have things wrong in places. Please email me if you have any comments, corrections or additions.
These pages were written for Firefox. I've tweaked the CSS so it looks moderately OK in IE, but it's not perfect.
