standalone server versus embedding in tomcat

[Martin Redington]

My app will receive a significant, but not a massive load. I expect to receive batched requests (batched from the client, unless XML-RPC supports batched requests ... I haven't seen any documentation for it), in small batches of four or five.

The application is a digital assets management application. I expect 10 to 20 concurrent users in my first installation, but I would like to be able to scale to hundreds or thousands of concurrent users.

Am I right in thinking that I am better off using a heavy-weight container, such as tomcat, rather than using the standalone servers?

cheers,
Martin
