Re: T5 - Authentication filter

[Eric Chatellier]

thanks, it' works

I check if user is authenticated and if not redirect to loginForm

but now I got a strange error using @ApplicationState

  @ApplicationState
  private SessionBean sessionBean;

In this form, when I try to log the user sessionBean.setLogged(true),
this excepion is thrown :

org.package.test.web.tapestry.base.SessionBean cannot be cast to
org.package.test.web.tapestry.base.SessionBean

The cast done by tapestry seams good, so how this exception can be throw ?

Hi Eric,
i think the best way to do it is to contrib to the Request handler pipilene
(http://tapestry.apache.org/tapestry5/tapestry-core/guide/request.html)
To contrib to a pipeline do it your AppModule:

 public RequestFilter buildTimingFilter(final Log log) {
    return new RequestFilter() {
        public boolean service(Request request, Response response,
            RequestHandler handler) throws IOException {
        long startTime = System.currentTimeMillis();
        try {
            // The reponsibility of a filter is to invoke the
            // corresponding method
            // in the handler. When you chain multiple filters
            // together, each filter
            // received a handler that is a bridge to the next
            // filter.
            return handler.service(request, response);

        } finally {
            long elapsed = System.currentTimeMillis() - startTime;
            log.info(String.format("Request time: %d ms", Long.valueOf
(elapsed)));
        }
        }
    };
    }


    /**
     * This is a contribution to the RequestHandler service configuration.
     * This is how we extend Tapestry using the timing filter. A common use
     * for this kind of filter is transaction management or security.
     */
    public void contributeRequestHandler(OrderedConfiguration<RequestFilter>
configuration, @InjectService("TimingFilter") RequestFilter filter) {
    // Each contribution to an ordered configuration has a name, When
    // necessary, you may
    // set constraints to precisely control the invocation order of the
    // contributed filter
    // within the pipeline.
    configuration.add("Timing", filter);
    }
