Hi
all,
I'll
be darned if I thought I had this problem licked. Here is the deal..I am running
3 web-apps in one application (one instace of Orion). Each web-app has its own
context if I am not mistaken, which means that one context can not share data
with any other context that is running. What I need to happen is allow 3
browsers access the 3 apps. All 3 apps point to the same one www dir on the
local drive, but each has a context root name of /admin/mediaName where
mediaName is radio, tv or cable. So, you would type in http://xxx.xxx.xxx.xxx/admin/radio
http://xxx.xxx.xxx.xxx/admin/tv or
http://xxx.xxx.xxx.xxx/admin/cable
Now the problem is, each has a database associated with them (we run 3
databases, one for each media type). A special HttpSession object (String type)
indicates the media type your in based on the Context path. I use the call
request.getContextPath() which returns /admin/radio, /admin/tv or /admin/cable
depending on what was typed, and store the Integer equivalent in the String
MediaType in the HttpSession. All servlets/actions (using struts framework) use
this stored value to determine what database to hit to get the data. This should
work, and does seem to work if I use the same one browser to log in with. If I
open two windows, and log in to radio, then cable (in the 2nd browser), then
pull up a query on some stuff that, it seems to show the radio data, even though
I am using a browser with the /admin/cable context in the URL line. When I run
the Console and look at the HttpSession data, /admin/cable shows a MediaType of
3 (Cable) which is correct, yet it still seems to be pulling radio
date.
So,
what I have figured out is that somehow, when I log in to radio first, then into
cable, even though a HttpSession is created in the /admin/cable web-app, the
actual session being retrieved is that of the /admin/radio web-app, which is the
only way I can explain it getting radio data. The reason this is the only way is
that the "logic" classes use the MediaType value set when the logic class is
created (a call to new with its constructor being passed the media type). So, I
think the problem is, why in a 2nd window, when I clearly log in to /admin/cable
and the session is created (in the Orion console) in the /admin/cable web-app,
is it somehow getting the /admin/radio session when the query is
performed.
I wish
there was some way to test this. I think I have an idea, but it would be kewl if
the Orion app showed an "access counter" to each object or something..if thats
possible.
Anyways, I just wanted to see if anyone else has ever
had this problem. Before answering, I do know before Servlet 2.2, that it was
impossible without some working, to allow multiple browsers of the same type
(MSIE for example) to have multiple sessions going. I thought I understood the
Servlet 2.2 spec to read that the context path in the URL of the request
determines where it looks for the session, then would use the cookie to get the
proper session for the request. It doesn't appear to be doing this for me, so if
I am wrong, please enlighten me.
Thanks.
