Hi,

We have web application running fine in production with 5 User in Tomcat 7, Now the user have increased from 5 to 200 users.

We need your idea/suggestions to improve the performance at tomcat 7 side however the application shouldn't crash if at a time 150 users login in to Application. What are the parameters we need to consider in Tomcat 7
when 150 user hits url at that moment.

Thanks,
Mamidi

Hello All,

we have deployed two different war files (example A War file, and B War File) in the same tomcat server and both are running fine , we try to connect A War file with the code of B War file code to get the results from War A
using the below code

URL url = new URL("http://localhost:7070/A/user/");
HttpURLConnection conn = (HttpURLConnection) url.openConnection();

tomcat is taking long time to fetch the result after it has established the connection, But the end of the day also we didn't get result. Why tomcat is too long time and doesnt give any results.

please let me know on this.

thanks,

Hi

i would like to know that suppose we got the connection object and created the statement object also
and we have closed the connection but we havn't close the statement object it automatically close the statement
or we need to close the statement explicitly

i heard that statement object will close automatically when we close the connection is it true ?

why threads are called as execution contexts or lightweight processes and also how they manage to keep moving in and out of running state without ever loosing the correctness of execution.
