public class SocialConnectedTag
extends BaseSocialConnectedTag

JSP Tag to return true/false if you're connected to a provider. Sample usages in JSP: Include at top of JSP: <%@ taglib prefix="social" uri="http://org.springframework/social" %> [ show some FB profile info ] OR another usage, more suitable for if you need to toggle on a page a connect check or multiple checks need to be made: [ Show Disconnect link ] [ Show Connect Button/link/form ] Note: You could use social:notConnected tag in place of using c:if and having to set the page scoped connectedToFB var, but it's a bit more efficient to not have to make the FB connection more than once on page
