can same servlet have multiple instance in container

[Pratibha Malhotra]

Hi
Single thread model is used to enforce one request accessing servlet at a time .
Servlet Api says, container may decide to have multiple instances of servlet if SingleThreadModel is implemented.
can we have more than one instance of a servlet in a container

A servlet can have more than one instances in the JVM. The number might be configured.
SingleThreadedModel indicats that at a time only one request will be allowed to access the one instance's service() method. Effectively it means that the service() method is synchronized.
Note : There might be more than one instances in SingleThreadedModel and more than one requests serviced. But only one request per instance.

[Bear Bibeault]

Note that SingleThreadedModel is deprecated and should not be used. Just write your servlets to be thread-safe and get on with it.

To quote from the Servlet API 2.3 - section 2.2
"For a servlet not hosted in a distributed environment (the default) the servlet must use only one instance per servlet declaration."
It then goes on to discuss the exception of the SingleThreadModel.
You really should get a copy of the API to answer these questions - it is the final authority.
