When in the Seam perspective, the menu item File->New->Example... opens the standard Eclipse example wizard which does not contains any of the JBoss examples. To get to the JBoss ones, you need to go to File->New->Example... then JBoss Tools->Project Examples.

This isn't very obvious, and makes it difficult to find the JBoss examples if you don't know where they are. It would be good if there was a "JBoss Examples" item in File->New, as well as or replacing the Eclipse one, or having them both in the same wizard.
