Re: [Springframework-developer] Spring Webflow PR3 and Redirects

Erwin,

Thanks for the response.

One more question for you: is it possible to redirect to a specific url 
(rather than a view).  I tried creating a custom view descriptor creator 
that did the following:

public class RedirectViewDescriptorCreator implements 
ViewDescriptorCreator {

    public ViewDescriptor createViewDescriptor(RequestContext 
requestContext) {
        final String service = (String) 
ContextUtils.getAttributeFromFlowScope(requestContext, 
WebConstants.SERVICE);
        final String ticket = (String) 
ContextUtils.getAttributeFromFlowScope(requestContext, WebConstants.TICKET);
        final Map model = new HashMap();
       
        model.put(WebConstants.TICKET, ticket);
       
        ViewDescriptor descriptor = new ViewDescriptor(service, model);
        descriptor.setRedirect(true);
       
        return descriptor;
    }
}

However, I get a an error message: javax.servlet.ServletException: Could 
not resolve view with name 
'redirect:https:/<machinename>:8443/contacts-cas/j_acegi_cas_security_check' 
in servlet with name 'cas'

Is there a proper way to handle redirects to URLs using Webflow?

Thanks
-Scott
