Hi Daniel,
In Tapestry there are so many good features concerning exception handling and
reporting, you have the flexibility to deal with them in whatever way suites
you best. Look at the onException tapestry event handler, it may be what you
want, so something like:
Object onException(Throwable e){
//activate redirect page here
return redirectPageObject();
}
I use this in a base page which saves me having to duplicate it in every page.
Dealing with container level exceptions (404, 500 etc) is also straightforward,
the link provided by Carl gives you some of the details, but it is also
possible (IMHO better) to just use a static html page or a .jsp page for your
Container level errors, for example:
<error-page>
<error-code>404</error-code>
<location>/error404.jsp</location>
</error-page>
and then place the error404.jsp file outside WEB-INF (i.e.: in WebContent) in
the applications root. So you wont need this any more:
<dispatcher>REQUEST</dispatcher>
<dispatcher>ERROR</dispatcher>
And it works almost all containers.
Cheers,
Peter

OnActivate()
When tapestry throws an excpetion it gets handled by the exception
report page - http://wiki.apache.org/tapestry/Tapestry5ExceptionPage
You can override that.
For other generic errors such as 404, check out
