fifo queue

Hi, 
I need to create on my tomcat 6.0 server a fifo queue of my http requests.
I want to process a single request at a time. 
Do you have an idea?
Thanks in advance.
Marco

Reduce the max http request threads to 1.

However,

1) the admin request will be queued like user ones
2) it's not a fifo, the socket that are served, one at a time, by http
thread are, i think, in the same order as the thread get notified by jvm

Add something like the following to your servlet

synchronized ( someObject )
               {
               do work
               }

But you'll need to be careful, as requests will block and clients
might time out if you are performing lengthy operations inside the
synchronized block.

Change your idea. Do you really need such a nasty hack?

Use command pattern. Process requests as usual, create Command objects 
and insert them into any queue you want.
