Tomcat Restarting

[ge...@yahoo.com]

Hi everybody,

I would like to know what really happen when tomcat is
restarted. This is because I need to know the risks of
restarting during production time. 

I mean, if, for example, a servlet is running and
at that moment I restart, does tomcat will wait until
the jvm finishes and give the generated response or it
will just kill every running/pending jvm process? 

In fact, is there any risk about missing financial
transactions?

Thank you ;-)

It first shutdown all applications then exit all http-thread.
During shutdown of application, it first make it unreacheable via http,
then call destroy on all servelt. It give time for currently running
requests to finish . I don't know if there is a timeout on this (like a
request taking 20 minutes to finish could be stopped).

If you are using "transaction" nothing will be done prior to commit and
everything will be done after comit. It's atomic (the principle of a
transaction) and not handle by java (its your database that is
implementing 2 steps commits).
