My team did something like this recently. We put a line in our
*.application file:
<page name="Exception" specification-path="/ErrorPage.page" />
Then we copied/modified the code from tapestry's error page so we could pipe
tapestry's stacktrace generation to log4j. The actual html/page file was
just our friendly message and layout with the original tapestry
implementation sitting in a hidden div to make life easy for developers.
Here's our code:
public abstract class ErrorPage extends BasePage {
@InjectObject("service:tapestry.globals.HttpServletResponse")
public abstract HttpServletResponse getResponse();
private static final Logger log =
Logger.getLogger("com.vms.adsite.pages.ErrorPage");
public abstract void setExceptions(ExceptionDescription[] exceptions);
public void setException(Throwable value) {
ExceptionAnalyzer analyzer = new ExceptionAnalyzer();
ExceptionDescription[] exceptions = analyzer.analyze(value);
setExceptions(exceptions);
String text = "";
for (ExceptionDescription exception : exceptions) {
text += "Class: " + exception.getExceptionClassName() +
"\n";
text += "Message: " + exception.getMessage() + "\n";
for (ExceptionProperty property : exception.getProperties())
{
text += "Property: " + property.getName() + " = " +
property.getValue() + "\n";
}
}
String[] stack = exceptions[exceptions.length-1].getStackTrace();
for (String stackItem : stack) {
text += stackItem + "\n";
}
log.error(text);
}
}

Subject: Logging error page into log4j
Hi all,
How do get the default error page to log into log4j?
I really dont need to overide the default error page (this is an internal
application) but I do need the errors logged. Any help is appreciated!
