RE: Is there such a beast ? (virtual directories)
This goes against the grain of the servlet spec. Generally, images would be something tied to a web application and would therefore be contained within the application war file (or directory) so that the webapp would be deployed as a single unit. ...but I'm not a puriest so have at it :P One option is to use a servlet that serves static files from directories and map that servlet in your web application's web.xml. This is nowhere near as robust or secure as putting httpd infront of your servlet containers. Again since this _could_ point outside the application directory it's a poor solution. Otherwise (as in Carl's suggestion): You can overlap URI mappings to contexts. So you can map: /app1 - fooApplication.war /app1/images - /usr/home/tomcat/images as long as your images directory is a deployable web application.

I've looked in the docs and googled, but haven't found a definitive 'no' answer (shouldn't life be that simple?). Thought I'd ask here. Is there such a thing as directory aliasing / virtual directories (like you get in Apache), available in Tomcat? so you'd specify that /images is *really* over here at /usr/local/some/funky/place/images I like to tell people they don't need Apache, unless they're doing special stuff.

RE: favicon question
You could map a servlet to /favicon.ico that serves different icons based on a cookie value that is set per context (with a custom Valve if you like) :oP Original Message Follows From: Mufaddal Khumri [EMAIL PROTECTED] Reply-To: Tomcat Users List [EMAIL PROTECTED] To: Tomcat Users List [EMAIL PROTECTED] Subject: favicon question Date: Fri, 9 Jul 2004 13:12:30 -0700 I have a webapp deployed under tomcat + apache.

Re: Design question ..
Unless it's too late in your implementation, I would decouple the reserve from the purchase. This way, the reserve transaction is shorter and more scalable and is not dependent on how fast you can enter CC and address data. This is nicer for the user too because they are getting close to real time data as opposed to 2 people, possibly simultaneously, trying to buy the same enrollment seat. My suggestion is: - a second table to hold reserved, un-purchased classes (same schema as enrollment table). When the purchase takes place move the reservation to the existing enrollment table you have now. - Check the max class limit by doing a union select on the reservation and enrollment tables. - if a reservation is not exercised within a certain timeout, remove it and reserve it for the first first wait-listed user (with necessary email notifications, etc). Checking the reservation table for expired reservations is obviously an async. process best left to a background thread, or scheduled task.

Date: Mon, 21 Jun 2004 12:37:04 -0700 Hi, I am in the process of writing a webapp that allows users to make a payment and register for a course. Using Apache -- Tomcat --- MySQL. The question is a design question i guess, unless there is something in Tomcat that I can leverage, which i might not know. I know that this is a design question , but since I am using Tomcat as my JSP/Servlet container and since the participants here are experts in this field , I thought that I might get some good pointers here. Lets take this scenario: User 1 and User 2 are trying to register for a course called Taekwando. The fee for registering is X amount. Also there is another course called Majagutamba and it costs Y amount. Both theses courses have exactly 1 seat remaining. Now lets say user 1 adds both these courses in his shopping cart, and user 2 does the same, since user 1 has not completed his transaction and paid the enrollment table wont have an entry for user1. (The Enrollment table keeps track of which user is enrolled in which course). Therefore both users have both those courses in their shopping carts. Now both of them proceed to checkout. They enter their credit card information and say submit. Both those users make payments and get enrolled for both those courses!!! Which is wrong , since both those courses could only enroll 1 more person, instead two new users were just added. To avoid the above problem one could implement a singleton synchronized Transaction object that would process shopping cart checkout in a queue. The problem with this approach are: 1. If anything goes wrong with any one transaction, it would hold up the entire queue. (Well we can have some sort of timeouts and take care of that.) 2. Since this is a syncrhonized singleton and if the traffic for registering for the courses is high, this would be a slow process for which the user will have to wait. Is there a better solution, algorithm, to do this ? Any help is appreciated.
