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

Answer 1

I know this thread is a year old now but having experienced the same problem I managed to solve the problem by setting a target server for my project.

i.e. right-click on your project and select 'Properties' -> 'Targeted Runtimes' and select the server you going to run your web app on (Tomcat 6 or 7).

Answer 2

I solved this issue. use below taglib

<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>

and add jstl-1.2.jar

Answer 3

I will throw one more solution into the mix. I downloaded a sample app and it was crimping only on this taglib. Turns out it didn't care for the single quotes around the attributes.

<%@ taglib prefix='c' uri='http://java.sun.com/jsp/jstl/core' %>

Once I changed those and made sure jstl.jar was in the web app, i was good to go.

Answer 4

I tried "validating" de *.jsp and *.xml files in eclipse with the validate tool.

"right click on directory/file ->- validate" and it worked!

Using eclipse juno.

Hope it helps!

Answer 5

You are probably targeting a server without built-in JSTL support (e.g. some version of Tomcat.) You will need to provision your own JSTL tag library.
