I am getting a strange behavior below: I am adding a model object in Spring Controller, when I access the same using jstl in jsp, I get nothing over there.
My project is REST based built on Java 1.8+ Tomcat 8.0+ Maven.
My maven project is named reporting having modules reporting-rest and reporting-dao. Jsp pages and controllers are located in reporting-rest.
pom. xml content in reporting-rest
