Hi, I have read a lot of accessible documentation regarding HAsingletons, however, I probably still do not understand one basic thing (when the startSingleton() method is invoked). I tried to do the HASingleton example shown in chapter 11.2 of: http://www.jboss.org/file-access/default/members/jbossas/freezone/docs/Cl... I thought the startSingleton() method is supposed to be invoked automatically when the application is deployed. Is this correct? In my case it is not so. Or am I supposed to call it from the JMX console? Thanks for an answer for such a basic question. Adam View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4205568#...
