[jboss-user] [JBoss Portal] - Problems about Injecting Services in the portlet context

Hi all, I read the Jportal 2.4.0 refereence guide and know in the jboss-portlet.xml ,we can Inject Services in the portlet context. so I do the same thing like the reference .But I do it in Portal 2.2.0, I don't think there is any diference. <portlet-app> <service-name>UserModule</service-name> <service-class>org.jboss.portal.identity.UserModule</service-class> <service-ref>:service=Module,type=User</service-ref> </portlet-app> then in my portlet i Write: UserModule userModule = (UserModule) getPortletContext().getAttribute("UserModule"); String userId = request.getParameters().getParameter("userid"); User user = userModule.findUserById(userId); but when I test, firstly, I login then I found userModule is null , and also user is null. so anyone can help me solve this problem? I want get the user object in the context. Thanks. ! View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3974742#...
