Sometimes deploying the app may not refresh jsp files on app server. So you might see in browser that app has old logic. To confirm that app server doesn’t have latest files go to app server. Typically:
$ssh -A appServer (https://sheberlik.wordpress.com/2017/09/20/connect-to-batch-server/)
Then switch to root
$ sudo su –
Then navigate to the folder
$cd /opt/tomcat/webapps/ROOT/WEB-INF/views/
then open the jsp file and see the content
If the file is old, just re-deploy via Jenkins
