JSTL in IntelliJ gives errors in JSP

Question

I\'m playing with Google App Engine in IntelliJ. I\'m trying to use JSTL tags in my JSPs. I\'ve tried two different URIs I found on the internet, and both of them give me er

Answer 1

Make sure that JSTL library jars are added to the module dependencies.

Answer 2

Add something like this to your pom.xml under the <dependencies> node (you are using maven, right?):

<dependency>
    <groupId>javax.servlet</groupId>
    <artifactId>jstl</artifactId>
    <version>2.5</version>
</dependency>

For gradle and other build systems see https://mvnrepository.com/artifact/javax.servlet/servlet-api/2.5

Also, make sure you pick a suitable version for your project. To see all available versions check here.

Answer 3

In my case, I had to download the .jar from apache (https://tomcat.apache.org/taglibs/standard/) and add to my project dependencies.

File > Project Structure > Modules > Dependencies

Answer 4

I resolved it by adding jstl-1.2 in the libraries.

• Right-click on "project"
• Then go into "open modules setting"
• Then in "libraries" click on the "+", then "add with maven"

• Click on the checkbox to download in a folder, change the folder path for .../WEB-INF/lib (create the lib folder)
