How to do dynamic URL redirects in Struts 2?

Question

I\'m trying to have my Struts2 app redirect to a generated URL. In this case, I want the URL to use the current date, or a date I looked up in a database. So /section/

One can redirect directly from an interceptor without regard to which action is involved.

In struts.xml

    
        ${#request.redirUrl}
    

In Interceptor

@Override
public String intercept(ActionInvocation ai) throws Exception
{
    final ActionContext context = ai.getInvocationContext();        
    HttpServletRequest request = (HttpServletRequest)context.get(StrutsStatics.HTTP_REQUEST);
    request.setAttribute("redirUrl", "http://the.new.target.org");
    return "redir";
}
