I do apologise if it appears I am being prolific with problems and I do apologise if
this is over critical, but it is testamount to the lack of quality documentation on

Hi,
Further, I will not be allowing reloading of webapps when the product
goes
live and the product does not have outofmemory issues so long as the

is left without reloading.
Even though your app is architected perfectly you won't allow reloads?
;) That's a good practice.
Thank you for

There is an article that mentions it is still quite slow for

since Tomcat
Yup, I understood all that. But what about hotswap?

Hi all,
The 3.x version of tomcat only did reloading of servlets, not on other
classes. Does the 4.x version do reloading of other classes as well. I'm
hoping it does and if it does, I'm hoping someone might provide some clues
as to why it's not working for me :).
Detection is done via
Futher, I also observed that my HTTPSession, though
is not New, does not have the attributes that were
put before the class reloading. Is this the expected
behaviour, or am I missing something?
I just observed, on using HTTPSessionBindingListener,
that when Tomcat 4.0.1 reloads any
, does not have the attributes that were
put before the class reloading. Is this the expected
behaviour, or am I missing something?

AFAIK tomcat doesn't support automatic reloading of classes. You do have to
restart.
