Create table users1 (uname varchar(20),pwd varchar(20));
insert into users1 values('yogeshb','pass1');
insert into users1 values('bhosale','pass2');
insert into users1 values('Pramod','nopass');

- Compile the servlets

- Start the Tomcat server

- Memory leak issues was coming becuas of in last session of tomcat connection with Oracle DB i kept ojdbc14.jar in lib folder of tomcat C:\Program Files\Apache Software Foundation\Tomcat 9.0\lib

and today while creating 37LoginWA again i kept ojdbc14.jar in lib folder of 37LoginWA C:\Program Files\Apache Software Foundation\Tomcat 9.0\webapps\37LoginWA\WEB-INF\lib

So remove/delete ojdbc14.jar from either of lib folder

- Test the web application


open the browser and test
