anonymous wrote : On the startup of the server the instance pool of session bean does not have any instance of bean. So what you are looking for is the minSize of the pool, which as far as i know, is not available. Why do you want the pool to contain an instance when the server has started? Maybe someone can point you to an alternate approach if you let us know what you are trying to do. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4139336#...
