Dear Wiki user, You have subscribed to a wiki page or wiki category on "Tapestry Wiki" for change notification.
The "Tapestry5HowToSendErrorPageAsEmail" page has been changed by WulfWechsung: http://wiki.apache.org/tapestry/Tapestry5HowToSendErrorPageAsEmail New page: Like the extensive and verbose error output of tapestry development mode? Don't want to scare your users away with the page? Want to be notified when your users run into trouble? === App Module == {{{ add this to to your app module: public static void contributeApplicationDefaults( MappedConfiguration<String, String> configuration) { configuration.add(USER_FRIENDLY_EXCEPTION_PAGE, "exception/Errors"); configuration.add(FULL_EXCEPTION_REPORT_PAGE, "exception/ExceptionReport"); } public RequestExceptionHandler buildAppRequestExceptionHandler( @Inject final ResponseRenderer responseRender, @Inject final PageDocumentGenerator generator, @Inject final ComponentSource componentSource, final @Symbol(AppModule.EMAILSERVER) String emailserver, final @Symbol(SymbolConstants.PRODUCTION_MODE) boolean productionMode, final @Symbol(AppModule.FULL_EXCEPTION_REPORT_PAGE) String exceptionPage, final @Symbol(AppModule.USER_FRIENDLY_EXCEPTION_PAGE) String userfriendly, final @Inject Response response) { final String sender = // your sender, symbol etc final String rcpt = // recepient of the email return new RequestExceptionHandler() { @Override public void handleRequestException(Throwable exception) throws IOException { // always log to console logger.error("Unexpected runtime exception: " + exception.getMessage(), exception); // let clients know something is up response.setStatus(HttpServletResponse.SC_INTERNAL_SERVER_ERROR); // get the page that will render the full non-production mode output Component exceptionReport = componentSource.getPage(exceptionPage); ((ExceptionReporter) exceptionReport).reportException(exception); if (productionMode) { try { String errorTrackId = System.currentTimeMillis() + ""; Document v = generator.render(exceptionPage); /** send email here **/ // this is a custom email builder so you'll have to substitute your own email sending code Email.from(sender).to(rcpt).withSubject("Error occured [tracking id=%s]", errorTrackId) .withContent("text/html", v.toString()).finish().sendVia(emailserver); /** Show your custom, user friendly page **/ /** In the original scenario I would show the tracker-id on the userfriendly error page ((ErrorTracker) userfiendly).setErrorID(errorTrackId); **/ Component userfiendly = componentSource.getPage(userfriendly); responseRender.renderPageMarkupResponse(userfriendly); } catch (Throwable t) { logger.error("Error in error handling. Ironic? Yes!", t); } } else { /** if in non-production we render the full exceptionPage right away **/ responseRender.renderPageMarkupResponse(exceptionPage); } } }; } public void contributeServiceOverride(MappedConfiguration<Class, Object> configuration, @Local RequestExceptionHandler handler) { configuration.add(RequestExceptionHandler.class, handler); } }}} === Exception Report === Unfortunately ExceptionReport ( the class that renders the exception pages per default) reads the production-mode symbol itself so we have to copy it. It's in org.apache.tapestry5.corelib.pages.ExceptionReport Copy it to your project and modify to always show the extensive report. I did that by stripping out the productionMode property and the <t:if><p:else></t:if> referencing it in the template. The contributeApplicationDefaults above assumes you have copied it to exception/ExceptionReport in your pages folder. == Error Page == The contributeApplicationDefaults above assumes you have created a page that display user-friendly errors ad exception/Errors in your pages folder. --------------------------------------------------------------------- To unsubscribe, e-mail: [email protected] For additional commands, e-mail: [email protected]
