Struts2 tags in a login page using JBoss Form Based Authentication

[Marco Garu]

Hello, I'm facing a little problem with struts 2 and form based authentication on JBoss. I managed to make almost everything work as i wanted, except 1 little thing: when i try to call a struts2 tag inside the login.jsp page i get the following error:

The Struts dispatcher cannot be found. This is usually caused by using Struts tags without the associated filter.Struts tags are only usable when the request has passed through its servlet filter, which initializes the Struts dispatcher needed for this tag

That's happening because instead of passing through the Struts2 servlet filter i'm redirected to the container form based authentication "handler". This is the related part of the web.xml file:

 
            <filter>
 	       <filter-name>struts2</filter-name>   
	       <filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>  
	    </filter>
	    
	    <filter-mapping>
	        <filter-name>struts2</filter-name>
	        <url-pattern>/*</url-pattern>
	    </filter-mapping>

            ....

       <security-constraint>
			<web-resource-collection>
				<web-resource-name>SecurePages</web-resource-name>
				<url-pattern>/secure/*</url-pattern>
				<http-method>POST</http-method>
				<http-method>GET</http-method>
			</web-resource-collection>
			
			<auth-constraint>
				<role-name>administrators</role-name>
			</auth-constraint>
       </security-constraint>

Is there any way to solve this problem?
(Sorry for my bad english!)
