I do not see any forums dedicated to the TrailBlazers documentation, so I add my comments here.
I just want to thank the developers of the EJB3.0 TrailBlazer. I have yet to see a more enjoyable, useful, and relavent description of the EJB3.0 (plus JBoss extensions) spec. on the net. Not even Sun's Java 5 Platform EE tutorial is as nice. I particularly like that I can exercise the components in real time while reading without having to download, compile, and deploy. The only thing that I would add is mentioning how the annotations need to be backed up with import statements.
