rahul22 Jan 29, 2013 7:13 AM

hi ,

in seam 2 we have @HttpError annotation .

i found this link http://www.parleys.com/#st=5&id=2204&sl=14

during the presentation they talked about @sendHttpError annotation in seam-catch.

but i can't find it , is there any other solution ???

if this is the solution then how i can use it ??? m using maven as build tool .

What Dan was talking about was simply an example. The closest thing is from Seam Rest: https://github.com/seam/rest/blob/develop/examples/exceptions/src/main/java/org/jboss/seam/rest/examples/exceptions/CatchExceptionHandlers.java

If you're not using Seam Rest then you'd have to create something similar, however, with JSF you have to know in which phase the exception occurred. If it was during RENDER_RESPONSE, you cannot send a redirect or HTTP error code.

hi,

one question ,
i can write as many methods inside one handler like :-

@HandlesExceptions
public class ExceptionHandler {

          void handleException(@Handles CaughtException<xyz> caught, HttpServletResponse response){
                    try {
                              response.sendError(404);
                              caught.handled();
                    } catch (IOException e) {
                              e.printStackTrace();
                    }
          }

          void handle(@Handles CaughtException<abc> caught, HttpServletResponse response){
                    try {
                              response.sendError(403);
                              caught.handled();
                    } catch (IOException e) {
                              e.printStackTrace();
                    }
          }
}

Yes, you can.

Also, If you are handling the same exception in different methods - see http://docs.jboss.org/seam/3/latest/reference/en-US/html/catch-client_usage.html#precedence
