List GuiceServletContextListener AFTER XWikiServletContextListener in web.xml. The servlet spec specifies that listeners are called in the order they are encountered in web.xml, and XWikiServletContextListener is the one that starts our component manager. > 2. How do I get the initialized PersonServiceXW instance from XWSocialModule? com.xpn.xwiki.web.Utils.getComponent(PersonServiceXW.class) -- Sergiu Dumitriu http://purl.org/net/sergiu/ _______________________________________________ devs mailing list [email protected] http://lists.xwiki.org/mailman/listinfo/devs
