Answer / anket dhulekar
Use listeners. Since you want to to know how many users have
logged in, so the login info would be stored in a session.
You can create a filter by extending HttpSessionListener,
and update a static variable when the session is created.
The value of this variable will store the number of users
currently logged on.

Answer / sunil
HttpSessionListener is Listener whenever session is created.
import javax.servlet.http.HttpSessionListener;
import javax.servlet.http.HttpSessionEvent;
public class SessionCounter implements HttpSessionListener {
private static int activeSessions = 0;
public void sessionCreated(HttpSessionEvent se) {
activeSessions++;
}
public void sessionDestroyed(HttpSessionEvent se) {
if(activeSessions > 0)
activeSessions--;
}
public static int getActiveSessions() {
return activeSessions;
}
}

Answer / ritesh parkhi
Number of users loged on website is depends on Pool Size of
there connection string. By Default MaxPoolSize=100 and
MinPolSize=0.
if Max pool size in 100 so only 100 user can loged in.If 101
user will try to simultaneously you will get TimeOut error
because your connectionstring wait to free one of connection
onject out of 100.

Answer / pradeep
1. If the website is static pages no data base interaction
then using static variable we can find out how many users
loged into the system.
2.If the webpage is data base centric and for accessing
any page we are retriving data then we can find the max. no
of connections .

Answer / raju
we need to write a servlet class, that is login servlet class. Whenever user going to login to the application ,server has to create login servelt object. so every time service method got executed for every user login. so write a private static int count variable as part of login servlet class and increment the counter value in service() method and store the counter value into application scope.
