Hi I am arun.The HttpSessionListener event is not firing up when a new session is created.The following program(ConcurrentUserTracker) increments the static variable "users" once when each session is created. The servlet DispalyUsers displays the number of current active sessions in a webapplication.But the output I am always getting is 0(zero) eventhough more than 5 sessions accesses the practice(Web Application Name).See I have localarea network thats why I can able to access the webapplication simultaneously with 5 sessions.
Web Application name is practice
Here is the following code which implements the HttpSessionListener interface
ConcurrentUserTracker.java
Here is the servlet code which displays the number of active sessions.
DisplayUsers.java
and finally here is the listener element which I added to the deployment descriptor web.xml of the webapplication(practice)
I added this element immediately after the <web-app> element.
then the <servlet> and <servlet-mapping> elements are deployed as follows
If you are going to post more than a line or two of your code, wrap that code in a set of UBB Code tags. Doing so will help to preserve your code's indenting, making it easier to read. If it is easier to read, more people will actaully read it and you will stand a better chance of getting help with your question.
I've added them to your original post in the hopes that it will help you get a meaningful answer.
There aren't many rules that you need to worry about here on the Ranch, but one that we take very seriously regards the use of proper names. Please take a look at the JavaRanch Naming Policy and adjust your display name to match it.
In particular, your display name must be a first and a last name separated by a space character, and must not be obviously fictitious.
