Make sure that both the below jars are present in the build path:

standard-1.1.2.jar
jstl-api-1.2.jar

Maven Dependencies are:

<dependency>
    <groupId>javax.servlet.jsp.jstl</groupId>
    <artifactId>jstl-api</artifactId>
    <version>$1.2</version>
</dependency>

<dependency>
   <groupId>taglibs</groupId>
   <artifactId>standard</artifactId>
   <version>1.1.2</version>
</dependency

Simply download javax servlet jsp jstl jar and add to your build path and WEB-INF lib if you simply developing dynamic web application   When you develop dynamic web application using maven then add javax servlet jsp jstl dependency in pom file   Thanks  nirmalrajsanjeev

I had the same problem even after I added jar files for jstl and standard  For me  it resolved after I added a Targeted runtime for my project   Go to Project Properties   Targeted Runtimes and select the server you are using  Tomcat 7 0 for me

you need to configure this in web xml as well Please refer below code    lt taglib gt       lt taglib-uri gt http   java sun com jsp jstl core lt  taglib-uri gt       lt taglib-location gt  WEB-INF lib c tld lt  taglib-location gt   lt  taglib gt    Please let me know if you still face any issue

To resolve the issue in jsp we have to use the dependency below in the pom file  If you dont use maven then download the dependency jar and add it to your WEB-INF directory   lt dependency gt       lt groupId gt jstl lt  groupId gt       lt artifactId gt jstl lt  artifactId gt       lt version gt 1 2 lt  version gt       lt scope gt compile lt  scope gt   lt  dependency gt   lt dependency gt       lt groupId gt taglibs lt  groupId gt       lt artifactId gt standard lt  artifactId gt       lt version gt 1 1 2 lt  version gt       lt scope gt compile lt  scope gt   lt  dependency gt

You may try to make the folder which include jsp-s become the source folder of eclipse  that solved the same problem of mine  As below         open project s properties  right click project  then choose the Properties    choose Java Build Path  select the Source tab  click Add Folder and choose the folder including your jsp-s  OK

The URI depends on the version of JSTL you are using  For Version 1 0 use   http   java sun com jstl core   and for 1 1  and later   you need to use   http   java sun com jsp jstl core

To make it work   Add jstl and standard jar files to your library   Hope it helps

create a libs folder in the inside WEB-INF directory and add jstl  standard jars as below

I have similar issue  why should we add external jar files when we are using maven   I have already included jstl maven dependency then also I encounter error  Can not find the tag library descriptor for  http   java sun com jsp jstl core     Then I include following dependency then error get solve  without including any single external jar file    lt dependency gt       lt groupId gt javax servlet lt  groupId gt       lt artifactId gt servlet-api lt  artifactId gt       lt version gt 2 5 lt  version gt   lt  dependency gt

As per snapshot the  main reason for error is that you are not defining c tld in lib folder causes such error   This lib content information about taglib

Downloading jstl-1 2 jar instead of jstl jar solves the problem

add the maven dependencies    lt dependency gt     lt groupId gt jstl lt  groupId gt     lt artifactId gt jstl lt  artifactId gt     lt version gt 1 2 lt  version gt     lt scope gt compile lt  scope gt   lt  dependency gt   lt dependency gt     lt groupId gt taglibs lt  groupId gt     lt artifactId gt standard lt  artifactId gt     lt version gt 1 1 2 lt  version gt     lt scope gt compile lt  scope gt   lt  dependency gt

If you are using maven your pom s  lt dependencies gt  tag should look like    lt dependencies gt       lt dependency gt           lt groupId gt javax servlet lt  groupId gt           lt artifactId gt servlet-api lt  artifactId gt           lt version gt 2 5 lt  version gt       lt  dependency gt       lt dependency gt           lt groupId gt javax servlet jsp jstl lt  groupId gt           lt artifactId gt javax servlet jsp jstl-api lt  artifactId gt           lt version gt 1 2 1 lt  version gt       lt  dependency gt       lt dependency gt           lt groupId gt taglibs lt  groupId gt           lt artifactId gt standard lt  artifactId gt           lt version gt 1 1 2 lt  version gt       lt  dependency gt   lt  dependencies gt    It works for me

Can not find the tag library descriptor for    http   java sun com jsp jstl core     Based on one of your previous questions you re using Tomcat 7  In that case you need JSTL 1 2  However  you ve there a jstl jar file while JSTL 1 2 has clearly the version number included like so jstl-1 2 jar  The sole filename jstl jar is typical for JSTL 1 0 and 1 1  This version requires a standard jar along in  WEB-INF lib which contains the necessary TLD files  However  in your particular case the standard jar is clearly missing in  WEB-INF lib and that s exactly the reason why the taglib URI couldn t be resolved  To solve this you must remove the wrong JAR file  download jstl-1 2 jar and drop it in its entirety in  WEB-INF lib  That s all  You do not need to extract it nor to fiddle in project s Build Path  Don t forget to remove that loose c tld file too  It absolutely doesn t belong there  This is indeed instructed in some poor tutorials or answers elsewhere in the Internet  This is a myth caused by a major misunderstanding and misconfiguration  There is never a need to have a loose JSTL TLD file in the classpath  also not in previous JSTL versions  In case you re using Maven  use the below coordinate   lt dependency gt       lt groupId gt javax servlet lt  groupId gt       lt artifactId gt jstl lt  artifactId gt       lt version gt 1 2 lt  version gt   lt  dependency gt   You should also make sure that your web xml is declared conform at least Servlet 2 4 and thus not as Servlet 2 3 or older  Otherwise EL expressions inside JSTL tags would in turn fail to work  Pick the highest version matching your target container and make sure that you don t have a  lt  DOCTYPE gt  anywhere in your web xml  Here s a Servlet 3 0  Tomcat 7  compatible example   lt  xml version  quot 1 0 quot  encoding  quot UTF-8 quot   gt   lt web-app     xmlns  quot http   java sun com xml ns javaee quot      xmlns xsi  quot http   www w3 org 2001 XMLSchema-instance quot      xsi schemaLocation  quot http   java sun com xml ns javaee http   java sun com xml ns javaee web-app 3 0 xsd quot      version  quot 3 0 quot  gt        lt  -- Config here  -- gt    lt  web-app gt      See also   Our JSTL wiki page  you can reach there by hovering the mouse on jstl and clicking info link  How to install JSTL  The absolute uri  http   java sun com jstl core cannot be resolved

You just need to include the standard jar file in your project build path

This works as well    lt dependency gt       lt scope gt compile lt  scope gt       lt groupId gt javax servlet jsp jstl lt  groupId gt       lt artifactId gt jstl-api lt  artifactId gt       lt version gt 1 2 lt  version gt   lt  dependency gt    lt dependency gt       lt groupId gt javax servlet lt  groupId gt       lt artifactId gt jstl lt  artifactId gt       lt version gt 1 2 lt  version gt   lt  dependency gt    so used jstl 1 2 instead of standard jar together with jstl-api 1 2

I got the same error message  Eclipse Enterprise 2020-06  Tomcat 8 5  dynamic web project   even after I downloaded version 1 2 5 of the jst library  here   dropped it into the  quot WEB-INF lib quot  folder and added  lt    taglib prefix  quot c quot  uri  quot http   java sun com jsp jstl core quot    gt  to the very top of the jsp file  Using version 1 2  here  instead fixed it

Use taglib definition in your JSP or better include it in every page by the first line    lt    taglib prefix  c  uri  http   java sun com jsp jstl core    gt    There s also fix jstl-1 2 dependency in your project  Also use servlet specification at least 2 4 in your web xml    The maven dependencies are  maven is a open source development tool     lt dependency gt     lt groupId gt jstl lt  groupId gt     lt artifactId gt jstl lt  artifactId gt     lt version gt 1 2 lt  version gt     lt scope gt compile lt  scope gt   lt  dependency gt   lt dependency gt     lt groupId gt taglibs lt  groupId gt     lt artifactId gt standard lt  artifactId gt     lt version gt 1 1 2 lt  version gt     lt scope gt compile lt  scope gt   lt  dependency gt    In the web xml start writing   lt  xml version  1 0  encoding  UTF-8   gt   lt web-app version  2 5       xmlns  http   java sun com xml ns javaee       xmlns xsi  http   www w3 org 2001 XMLSchema-instance       xsi schemaLocation  http   java sun com xml ns javaee      http   java sun com xml ns javaee web-app 2 5 xsd  gt    EDIT   I d like to add a note that  informatik01 has mentioned in the comment about newer version of JSTL libraries available from Maven repository   JSTL version 1 2 1 API and JSTL 1 2 1

This is a very common error while working on JSTL   To solve this error simply  -    Download jstl-1 1 2 jar and standard-1 1 2 jar And then just paste them in lib folder under WEB-INF of your Dynamic Web App project    You will find the error has gone now   Hope this helps

Well  I have read this post and seems it is not good enough to fix this issue    Spring based application on the tomcat 8 will not work    Here is the solution   Step 1   Add the following dependency in your pom xml   lt  -- JSTL Support -- gt         lt dependency gt       lt groupId gt javax servlet lt  groupId gt       lt artifactId gt javax servlet-api lt  artifactId gt       lt version gt 3 1 0 lt  version gt   lt  dependency gt   lt dependency gt       lt groupId gt javax servlet jsp lt  groupId gt       lt artifactId gt javax servlet jsp-api lt  artifactId gt       lt version gt 2 3 1 lt  version gt   lt  dependency gt   lt dependency gt       lt groupId gt javax servlet lt  groupId gt       lt artifactId gt jstl lt  artifactId gt       lt version gt 1 2 lt  version gt   lt  dependency gt    Step 2   Add All following two statement in your JSP page  ensure that you are using isELIgnored  false  attribute in  lt    page    tag   lt    page language  java  contentType  text html  charset ISO-8859-1  isELIgnored  false  pageEncoding  ISO-8859-1   gt   lt    taglib prefix  c  uri  http   java sun com jsp jstl core   gt    Step 3   Remove all the other configuration that you have done till now in web xml or anywhere else     Step 4   Clean the Tomcat and restart Tomcat    Side Note   Actually  JSTL will work with only 3 x Servlet specifications on Tomcat 8     http   www kriblog com j2ee jsp jstl-with-spring-4-on-tomcat-8 html
