Exception/Error page
Hi.
How can I override Tapestry's default exception page (line precise), with
something more friendly for end user (lets' say just 'Internal server error'
message), and just log exception trace to file ?
I was expecting some org.tapestry.error-page application-level property, but
cannot spot any... :-(
Regards,
Vjeran

Harish, thanx a bunch.
And if anyone would count one newbie wishes, I would suggest that this
procedure has to be included in user guide, and putting one chapter in next
release of TIA book would be my suggestion also. Logging this runtime
exceptions into file by deafult would also be good, because one more copy of
exception report (through commons-logging, beside those on screen) would do
no harm to anyone.
Thanx once again, you saved my day.

What class is your exception page pointing to? What you want to do is
override the exception page which means drop in a page named
exception.html and exception.page in WEB-INF and have your
exception.page point to your exception class which should have a
setException(Throwable t) method. Tapestry will call this method in the
event of an exception. From within this method you can log your
exception to where ever you want. Take a look at Tapestry's
org.apache.tapestry.pages.Exception.java and
org.apache.tapestry.util.exception.ExceptionAnalyzer.java

Aaaarrgh ... I'm little frustrated ... :-(
Don't get me wrong, I am, although short timed, huge Tapestry fan, but
specifying error page is wide-spread/well-known requirement in all web
frameworks, which are far below this one, and somehow I cannot find how to
do it properly in Tapestry. Not in user guide, not in TIA book.
"Line-precise" exception page is nice feature for developing on my local
computer, but when deployed, my scheme should look as always : "Internal
Server Error" page (hiding internals from end users) and exception gets
logged in file. I can see also some ExceptionDisplay component in library,
but there are no examples how to use it.
And now most serious thing, and I hope it's just me and my lack of knowledge
about Tapestry - I can live with my client have to see Tapestry's exception
page with all detals, but I was shocked when I noticed that same exception
(presented on exception page) *isn't propagated* to Log4j loggers (file
appender) ? Plase tell me that I had put something wrong, because I dunno
how will I take a look at some problem when my client calls me and tells me
that something has crashed yesterday night, and I cannot see anything in
file logs ? I certainly cannot tell them to reproduce the error and
copy-paste exception page ...
And considering changing exception page ... I found some docs about it only
in some outdated tutorial (Google search), and I'm confused why this chapter
doesn't still exist somewhere :
http://tapestry-tutorial.cloudnine.net.nz/pages-example.html
Basicaly, it suggest same thing as you have written below, but unfortunately
somehow it doesn't work also :
Unable to present exception page.
Session id: 0BE415D553F38857B4641C68B3A55A04
Client address: 127.0.0.1

'<parsed expression>' of

ognl.NoSuchPropertyException: exception

Please HELP me ASAP. I cannot deploy my application withut exception
logging...

Simply drop in your exception.html and exception.page in WEB-INF.
