Hi,

This is core tagging library used to work with request, response, data rending data. This has special tags start with prefix set in attribute. it is more faster than scriptlet code and jsp tags on jsp pages.

Using jstl can be good practice for coding on jsp

Cheers,

Krutik

The fact that a URI looks like a URL can be confusing, but it's just an identifier. It does not mean that any network connection is being made.

In fact if you crack open the c.tld file you find in the jstl jar files, you will see this uri declared:

<taglib 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-jsptaglibrary_2_1.xsd"
    version="2.1">
    
  <description>JSTL 1.1 core library</description>
  <display-name>JSTL core</display-name>
  <tlib-version>1.1</tlib-version>
  <short-name>c</short-name>


  <uri>http://java.sun.com/jsp/jstl/core</uri>
