hi!
i have a few questions about the resource management of rap/equinox. since
one project is going to be tested in a productive environment soon, i
wanted to ask whether i have to take some aspects into consideration or if
rap/equinox deals with them already.
for example, i added a beforeDestroy listener to the session which simply
does a system.out.println, i noticed that the session is not destroyed as
soon as the user closes the browser window. what about the object that are
created within this session?
does the "default" configuration (which means no special configuration
regarding the servlet-side) already scale well or do i have to take some
precautions? i just ask because i don't know much about the
resource/session management of rap/equinox and i'm afraid that the jvm
might run out of memory, and i don't know how much memory i should assign
to the jvm :)).
maybe someone can give me a short overview or if there are links regarding
this topic i'd be very grateful if someone can contribute some.
thx in advance!
-ben

Hi,
it's true that the session isn't destroyed immediately if the user closes
the browser window. To keep it short - RAP relies on the session timeout
mechanism of the underlying servlet container (configuration via web.xml, in
case of running equinox standalone there's a system parameter). And there is
not a general answer to the question of the optimal timeout settings for
webapps - it depends on your application, number of concurrent users,
available memory etc.
Ciao
