Hi there:
When I make a deploy, I have the problem that if I make changes to classes
that where serialized as part of the session (this is natural in a wicket
app, as it is mine), every user that was already logged from before the
deploy gets this ugly "local class incompatible" error, which to make things
worse is not possible to catch by the app, and the user only sees an empty
white page.
The error makes sense, but I'd like to ask:
- Is there a way I can programatically (or from the admin console would be
best) make all session cookies expire?
- Would it be possible to make this exception "cacheable" by the app, so we
can at least show some proper message?
At the end of this email I'm adding the exception stack trace.
Thanks in advance,
Esteban
