Puma Service/User Details in (Theme, Servlet, Portlet)

a) Get details of User in Theme for loggedIn User
1) Use following tag lib to get basic user attribute value
<%@ taglib uri="http://www.ibm.com/xmlns/prod/websphere/portal/v6.0/portal-fmt" prefix="portal-fmt" %>
<portal-fmt:user attribute="givenName" /> <portal-fmt:user attribute="sn" />
2) To get other info like in which group user belongs to
<%
com.ibm.portal.puma.User portalUser=  (com.ibm.portal.puma.User) request.getAttribute(com.ibm.portal.RequestConstants.REQUEST_USER_OBJECT);
 if(portalUser!=null) {
    java.util.List groups = portalUser.getGroups();
        for (int i=0; i< groups.size() ; i++){
            com.ibm.portal.puma.Group grp = (com.ibm.portal.puma.Group)groups.get(i);
        }
}
%>
