Custom Exception Page

[George Christman]

Hi guys, I'm trying to implement a custom exception page for production
mode only. Using Jumpstart I was able to get the page to work without
issue.

http://jumpstart.doublenegative.com.au/jumpstart/examples/infrastructure/exceptionreportpage
http://wiki.apache.org/tapestry/Tapestry5ExceptionPage

however I do not know how to use tapestries default exception page during
dev.

In my old 5.3.7 app, I was able to do something like this. I'm assuming
there must be a simpler way in 5.4?

public class ErrorReport implements ExceptionReporter {

    @Property
    private Throwable exception;

    public void reportException(Throwable exception) {
        this.exception = exception;
    }

}

public class ProductionExceptionHandler {

    private final Logger logger;
    private final ResponseRenderer renderer;
    private final ComponentSource componentSource;

    private final static String ERROR_PAGE_NAME = "ErrorReport";

    public ProductionExceptionHandler(Logger logger, ResponseRenderer
renderer, ComponentSource componentSource) {
        this.logger = logger;
        this.renderer = renderer;
        this.componentSource = componentSource;
    }

    public void handle(Throwable exception) throws IOException {
        //Send email

        ExceptionReporter errorPage = (ExceptionReporter)
componentSource.getPage(ERROR_PAGE_NAME);
        errorPage.reportException(exception);

        renderer.renderPageMarkupResponse(ERROR_PAGE_NAME);
    }

}


    @Match("RequestExceptionHandler")       // service to advise
    @Order("after:requestExceptionHandler") // advice id from
tapestry-security SecurityModule
    public static void adviseProductionExceptionHandler(
            MethodAdviceReceiver receiver,
            final Logger logger,
            final @Symbol(SymbolConstants.PRODUCTION_MODE) boolean
productionMode,
            final ProductionExceptionHandler handler) {

        Method handleMethod;

        try {
            Class<?> serviceInterface = receiver.getInterface();
            handleMethod =
serviceInterface.getMethod(EXCEPTION_HANDLE_METHOD_NAME, Throwable.class);
        } catch (Exception e) {
            throw new RuntimeException("Can't find method
RequestExceptionHandler." + EXCEPTION_HANDLE_METHOD_NAME + ". Changed
API?", e);
        }

        MethodAdvice advice = new MethodAdvice() {
            public void advise(MethodInvocation invocation) {
                if (productionMode) {
                    Throwable exception = (Throwable)
invocation.getParameter(0);
                    try {
                        handler.handle(exception);
                    } catch (IOException e) {
                        logger.error("Error in ProductionExceptionHandler",
e);
                        invocation.proceed();
                    }
                } else {
                    invocation.proceed();
                }
            }
        };

        receiver.adviseMethod(handleMethod, advice);
    }
