I've had a look at the archives and Jason Hunters book, however I still find
myself unsure.
What I want to do is to create a thread that will pre-fetch data into a
specific session. The first servlet will create the session, kick off the
prefetch thread and return. Subsequent servlets will make use of the
prefetched data from the session and return immediately (they may also start
other prefetch threads or retrieve extra data themselves as required). The
last (logoff) servlet will invalidate the session.
If I pass the HttpSession to the thread it seems like I should be able to
save the data into it without too many worries. Will this stop the session
from expiring normally? Are there any other gotchas I'm missing?
I obviously want any running threads to end cleanly when the session ends
for whatever reason. Should the thread implement HttpSessionBindingListener
for this or should I just trap exceptions?
I'm not sure if this will effect any suggestions/preoblems but I'm using
VAJ/WebSphere 3.02 :-(
