How to resolve : Can not find the tag library descriptor for “http://java.sun.com/jsp/jstl/core” [duplicate]

Answer 1

As @ace mentioned you will need the jstl.jar in your project, so if you are using maven, you could add this dependency:

    jstl
    jstl
    1.2

Source: http://mvnrepository.com/artifact/jstl/jstl/

Hope it helps.

EDIT: Most of servers already have this dependency, if you add it using maven it may cause version conflicts (like Method/ClassNotFoundException) if you don't configure the server well, so it's better set a target server for your project, as @willix mentioned.
