Any ideas on how to do that ?
You need more than one way to get to information as people will use different strategies to find out about a new technology. I personally like to know at a glance the scope of a project, so I preferred the original approach (and the one taken on the ActiveMQ site) of having lots of left menu items for each topic, component or significant point.
The documentation is probably weakest on practical examples, judging by the sort of support queries coming in. There should be explicit tutorials for binding to a foreign web service, exposing a web service, wrapping a POJO, creating JBI components, packaging and deploying using su/sa, applying security.
We also need to do a better job of keeping these up to date and making it clear which documentation refers to which release.
