Can any one help me out in understanding what are the best practices in developing a JBoss portal application. 1) Is it good to alter portal.sar's defualt-object.xml for making your portal default. 2) Is it good to deploy your web application in jboss-portal.sar. 3) Is it good to have your own portal.sar. 4) Is it good to have your portal.sar outside the jboss-portal.sar. 5) Is it good to have our own Header Portlet, instead of altering the header.jsp/tabs.jsp 6) Whats the best way to generate bread crumbs. Making it as a portlet? 7) If we have our-own sar going into jboss-portal.sar, how to hot deploy. I have some EventListeners which need to be registered through jboss-service.xml and so i happened to put them in my own sar and put it under deploy of jboss server. But i am facing some issues in there. One unique issue is when i am trying to access Navigation.getPortalRuntimeContext(), some times it works fine and somtimes.. It throws me a NullPointerException. Is it something to do with my sar being outside. any ones explination on these issues is highly appreciated.
