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);
}

hi everyone
I'm starting using Tapestry 5.0.4 and i'm tying to implement an
authentication filter.
In some tapestry 4 samples, code was :
public abstract class AuthenticatedPage implements PageValidateListener {
public void pageValidate(PageEvent event) {
if (!isSessionBeanExist() ||
getSessionBean().getUid()==-1) {
Login loginPage = (Login)getRequestCycle()
.getPage("Login");
loginPage.setCallback(new PageCallback(this));
throw new PageRedirectException(loginPage);
}
}
}
public class ProjectList extends AuthenticatedPage {
[...]
}
but i can't find the way to do it in tapestry 5.
thanks in advance for help, and sorry for my bad english ;)
