user configuration

is there any way to configure the number of users who can access the tomcat server at a time?
if so, tell me. ( i mean number of users who can hit the server a time)

There is a maxThreads attribute but I'm not sure I understand what you mean by number of users who can hit Tomcat at one time.

Do you mean actual concurrent HTTP requests or number of active sessions that can occur at the same time?

Explain, exactly what you're trying to do and we might be able to come up with a solution for you.

yes.i meant the number of concurrent http requests coming in to the tomcat server.......

Before we continue this discussion, would you mind fixing your screen name?
Bear gave you the links to our naming policy and the page for fixing it.

Here they are again.

Thanks for fixing your name.

Have a look at the maxThreads, maxSpareThreads, minSpareThreads entries in this page for more information on configuring the number of concurrent hits Tomcat will accept.
