a) I don't think this works ;) - you will find (AFAIK) that any non-bijected fields are lost/wrong between requests (remember stateless beans are assigned from a pool, so this may *not* show up under low load). b) Not as efficient in a clustered environment (yes, Seam provides support for clustering javabeans, but it's not as good as that provided by EJB3). Reasons not to use SLSB/SFSB - needing a local interface which is a pita :) View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4071536#...
