    Default

    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?
