http://java.sun.com/jsp/jstl/core cannot be resolved in either web.xml or the jar files deployed with this application
eclipse, jsp, jstl, mysql, tomcat
Solution
Turns out my JSP version was in fact 2.2, I remember opening up an about page in Eclipse to be able to get this information, but was not able to re find it for answering purposes. However, I will update this answer accordingly if necessary.
Libraries used:
(1) javax.servlet.jsp.jstl-1.2.1.jar
(2) javax.servlet.jsp.jstl-api-1.2.1.jar
(3) javax.servlet-api-3.0.1.jar
(4) mysql-connector-java-5.1.23-bin.jar
pom.xml referenced from http://java.net/projects/jsp/sources/svn/content/trunk/impl/pom.xml?rev=1440
The versions of the dependencies are:
a) javax.servlet-api 3.1. (b) javax.el-api 2.2.1. (c) javax.servlet.jsp-api 1.2.1 (d) javax.servlet.jsp.jstl-api 1.2.1. (e) jstl 1.2. (f) jstl-imp 1.2.
Reference in web.xml:

Problem
I am new to jsp web development and debugging my application to be able to read off a database gives the following error: ``` The absolute uri: http://java.sun.com/jsp/jstl/core cannot be resolved in either web.xml or the jar files deployed with this application ``` I researched the internet on multiple sites regarding this issue for so long, unable to fix anything.
