Hi,
For this problem I would say it would be best to use IIS and Tomcat combo Because
IIS can authenticate users by using NTLM authentication scheme. This means that users

Authenticaton in IIS).

a serialized java object, assuming it's not to big. It'd probably be easier
to use a nice short token however.

There's a couple of different ways to handle this.
1. do not do it in real time. this is the easiest solution, but it
means a human has to be the one who figures who gets what class.
2. use JMS to update each user's session and make it so that once the
class has no more entries, no one else can a

decremented. If the transaction isn't finalized either because of an
error or timeout, just release the seat for someone else. When they do

Most commercial databases implement a solution to this problem since it is
fairly common. For MySQL, you must use the InnoDB engine (at least for now).
You use the concept of transaction. To do this, you must turn the AutoCommit

Probably the easiest way to handle this is simply to have a constraint on
your database that says a record cannot be added if some field is 0 (or a
unique constraint, depending on how your table is keyed). Then, just catch

I understand this approach. The problem is that the course table has a
field called "maxregistration" if this field is set to -1 it means that
there is no limit. If there is a value in this field, it will be >= 1.

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
you don't necessarily need to lock or synchronize in a "first come

temporary order id. Once the order goes through, the real order ID is
emailed to the user.

Craig, nevermind, it's because I was still casting the object using an
