T5 How to tell T5 to send 301 (moved permanently)

Hi,

when I return a link in some method T5 send a 302. I want to send a 301
to the client. Is this possible with tapestry, without using the servlet
stuff?

Thanx && cheers,
Martn

Hi,

I actually extended HttpStatusCode to take care of this.

Here's the code:

HttpStatusCode.java:

public class HttpStatusCode
     implements Serializable {

   private final int statusCode;
   private final String location;

   public HttpStatusCode(int statusCode) {
     this.statusCode = statusCode;
     this.location = "";
   }

   public HttpStatusCode(int statusCode, String location) {
     this.statusCode = statusCode;
     this.location = location;
   }

   public HttpStatusCode(int statusCode, Link link) {
     this(statusCode, link.toRedirectURI());
   }

   public HttpStatusCode(int statusCode, URL url) {
     this(statusCode, url.toExternalForm());
   }

   public int getStatusCode() {
     return statusCode;
   }

   public String getLocation() {
     return location;
   }
}


AppModule.java:

   public static void contributeComponentEventResultProcessor(
       MappedConfiguration<Class, ComponentEventResultProcessor> 
configuration, final Response response) {
     configuration.add(HttpStatusCode.class, new 
ComponentEventResultProcessor<HttpStatusCode>() {
       public void processResultValue(HttpStatusCode value) throws 
IOException {
         if (!value.getLocation().isEmpty()) 
response.setHeader("Location", value.getLocation());
         response.sendError(value.getStatusCode(), "");
       }
     });
   }

Now all you need to do is:

   return new HttpStatusCode(HttpServletResponse.SC_MOVED_PERMANENTLY, 
link);

Link can be a String, a Link or a URL.

I haven't tried it, but I think it should work with the approach described in

http://www.nabble.com/Index-page-context-and-404-response-to16649174.html#a16649174

It works fine for 404, you might have to extend it to include the URL
to the page you are redirecting to.

Hth,

Lutz
