Can anybody let me know if i am missing anything?

It looks like you're using the Facebook init tag from M1. That version of the tag was just a .tag file that uses Spring's JSP tag library to do some of its work. For that to work, you'll need the Spring MVC module in your classpath. (Maven group/artifact: org.springframework/spring-webmvc).

Spring Social 1.0.0 M2 changed how that tag works, however. It no longer depends on Spring's JSP tag library and is now implemented as a Java class (not a .tag file). Moving up to the latest stuff should remedy your problem.

Thanks habuma.

I am right now using Spring Social 1.0.0 M2 and i don't get any such error. But in my controller class i get @FacebookCookieValue as null.

Code:

I have the following in my applicationContext.xml file. <bean class="org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping"/> <bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter"> <property name="customArgumentResolver" ref="facebookWebArgResolver"/> </bean> <bean id="facebookWebArgResolver" class="org.springframework.social.facebook.web.FacebookWebArgumentResolver"> <constructor-arg name="appId" value="${facebook.appId}"/> <constructor-arg name="appSecret" value="${facebook.appSecret}"/> </bean> and the following method in my Controller class @RequestMapping(value="fb.htm", method=RequestMethod.POST) public String connectAccountToFacebook(@FacebookCookieValue String fbCookieVal) { String fbC = fbCookieVal; return null; } I get the value of fbCookieVal as null. Also in my JSP i have the following code : <%@ taglib uri="http://www.springframework.org/spring-social/facebook/tags" prefix="facebook" %> <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.3/jquery.min.js" type="text/javascript"></script> <%/* Connect to Facebook */ %> <form id="fb_signin" action="fb.htm" method="post"> <div class="formInfo"> </div> <div id="fb-root"></div> <p><fb:login-button onlogin="$('#fb_signin').submit();" v="2" length="long">Connect to Facebook</fb:login-button></p> </form> <facebook:init appId="${facebook.appId}" />

Could you please let me know what i am missing?
