Answer 1

If you are still getting errors after following the instructions provided by Shams UI Azeem, you may need to add the JSTL library to the WAR Exploded artifact. To do this:

1. Go to Project Structure. Under Project Settings, select Artifacts. On the bottom of the menu box, there may be a message which mentions that the JSTL library used is not included in the WAR.

2a. Message visible. If the message is displayed, there should be a Fix button next to it. Click this Fix button. Select "add javax.servlet:jstl:1.2 to the artifact".

2b. Message not visible. If the message is not displayed, then look above to see if the javax.servet:jstl:1.2 (Project Library) is underneath the Available Elements column. If it is, right click it and select "Put into /WEB-INF/lib".

If you are working with Maven, the Fix message will not appear, though you will still need to do this.

Answer 2

First add this to the top of your .jsp file:

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

It will still give syntax error but you can fix that by adding javax.servlet:jstl:1.2 as a module dependency. To do that, follow these steps:

1. Click your project name and press F4 to bring up the module settings dialog.
2. Then go to the dependencies tab in the modules section.
3. Click the green + icon → library → From Maven.
4. Search for javax.servlet:jstl:1.2 in the search bar and press OK and it will download and add the above mentioned library as a module.
5. Now you should not have any kind of syntax error.

Answer 3

If you are using maven, add following code in pom.xml inside the <dependencies></dependencies> tag

<!-- https://mvnrepository.com/artifact/javax.servlet/jstl -->
<dependency>
    <groupId>javax.servlet</groupId>
    <artifactId>jstl</artifactId>
    <version>1.2</version>
</dependency>

Answer 4

Add below dependency to your pom.xml

<!-- https://mvnrepository.com/artifact/javax.servlet/jstl -->
<dependency>
    <groupId>javax.servlet</groupId>
    <artifactId>jstl</artifactId>
    <version>1.2</version>
</dependency>
