RE: Custom exception page

[Greg.L.Cormier]

Thanks Steve.

So in Exception.html I could just have a

<span jwcid="@ExceptionDisplay" exceptions="ognl:exceptionDescription" />

?

Thanks,
Greg

Look at tapestry's ExceptionDisplay component source.  It uses something 
called an ExceptionAnalyzer and also displays the contents of the 
ExceptionDescription.getProperties().

I've got a custom exception page that writes to log4j.  Here's what I 
use to get the text:

    public void logException(Throwable value) {
        ExceptionAnalyzer analyzer = new ExceptionAnalyzer();
        ExceptionDescription[] exceptions = analyzer.analyze(value);
        setExceptions(exceptions);
        StringBuffer text = new StringBuffer();
        for (ExceptionDescription exception : exceptions) {
            text.append("Class: " + exception.getExceptionClassName() + 
"\n");
            text.append("Message: " + exception.getMessage() + "\n");
            for (ExceptionProperty property : exception.getProperties()) {
                text.append("Property: " + property.getName() + " = " + 
property.getValue() + "\n");
            }
        }
        String[] stack = exceptions[exceptions.length-1].getStackTrace();
        for (String stackItem : stack) {
            text.append(stackItem + "\n");
        }
        log.error(text.toString());
    }
