The action instance itself doesnt have any member variables does it?
If you store stuff in the HTTPSession each user will have their own session
context - it shouldnt (be possible to) get mixed up like that (unless both
requests are actually by the same user (in the same session) - in which case
you may have troubles like those you describe).

Subject: Huge action instance synchronization problem



My problem: I have a search action. When 2 (or more) users submit the
search form simultaniously, because the seach usually takes about 1-2
seconds, the same action instance is rethrieved to complete the search
and sessions are combined like this: the action makes the search for the
first session but does not finish until the second search is performed
and because the resultset is divided into pages and this divisation is
stored into session, both pages with results are put in the second
session, and the second user shall be dispalyed the correct results but
the first shall have null pointer exception because in his session there
is no object representing the divisation of the resultset on pages.

The problem in my opinion is because the same action instance performs
the same task for the 2 users and so the sessions are combined, which is
a huge problem, because like this every method of an action (dispatch
action) that takes a while to complete shall have the same problem.

Please advise me how to solve this problem.
Thank you ,
Dan Bunea

PS Dear Craig , I am sorry to bother you but this problem is very
urgent, as the project is in final stages and this is a potentially huge
problem.
 I have read that each action is instantiated only once in the
RequestProcessor and for each request the action is rethrieved and its
methods executed, but I have also read that this is not synchronized.
