Invalidate session
Hello,
how can a session be invalidadted gracefully? Simply calling
session.invalidate() (where session for example was retrieved using
WebRequest.getSession()) does invalidate exception, but will result
in an exception later on in AbstractEngine. Here, the state manager
is flushed which will complain about the missing session.
The exception is catched by AbstractEngine. But an error is logged.
Any ideas? Thanks.
Regards,
Christian

There's a very good sample developped by Howard in the Vlib sample
bundled with Tapestry ...

Yes, I have googled a bit and found some small discussions. But
they were not to helpful.

Well, it is more than an annoyance when you deploy in Tomcat 5.5.15,
where the exception reporter gets a null pointer exception from the
session.getID(). The user will get a tomcat error report and not the
logout page.

This has been discussed a few times before. For example,
http://article.gmane.org/gmane.comp.java.tapestry.user/31641/match=illegalstateexception
As you say, Tapestry doesn't allow the exception to bubble up to the
user, but it does put a worrisome stack trace in the log. The Tapestry
developers weren't highly motivated to fix this minor annoyance :-) so
I just ignored it for a while, and then worked around it in my custom
Engine. It's not pretty but hey, it's a work-around.
private static final String CLIENT_ABORT_EXCEPTION_NAME =
"org.apache.catalina.connector.ClientAbortException";
private static final String ILLEGAL_STATE_EXCEPTION_NAME =
"java.lang.IllegalStateException";
private static final String SESSION_INVALIDATED =
"Session already invalidated";
private static final String UNABLE_TO_RESET =
"Unable to reset response buffer";
public void reportException(String reportTitle, Throwable cause)
{
ExceptionDescription ed = null;
// Don't log ClientAbortExceptions at all.
ExceptionDescription[] edArray = new
ExceptionAnalyzer().analyze(cause);
assert edArray != null;
if (edArray.length > 0) {
ed = edArray[0];
}
if
(ed.getExceptionClassName().equals(CLIENT_ABORT_EXCEPTION_NAME)) {
log.debug("Not logging ClientAbort exc'n");
return;
}
// Avoid the ugly stack trace that Tapestry puts in the log for the
// IllegalStateException when a user logs out.
if (ed.getExceptionClassName().equals(ILLEGAL_STATE_EXCEPTION_NAME)
&& (ed.getMessage().indexOf(SESSION_INVALIDATED) != -1
|| ed.getMessage().indexOf(UNABLE_TO_RESET) != -1))
{
// This debug message doesn't show up for some reason.
log.debug("Not logging session-already-invalidated exc'n");
return;
}
log.error(reportTitle);
//.... the rest mimics what Tapestry's reportException() does.

I do it in the invalidate.jsp and then send redirect to the client to a desired page.
