Some Error in Expression Language Configuration

Question

One EL config issue is there:

<%@ page isELIgnored="false" %>
${10 + 15}<br>

While using the above statements I am getting the perfect output i.e. 25. Now I want to isELIgnored="false" for the entire web application so I modified the web.xml as:

<?xml version="1.0" encoding="UTF-8"?>
<web-app>
    <jsp-config>
        <jsp-property-group>
            <url-pattern>*.jsp</url-pattern>
            <el-ignored>false</el-ignored>
        </jsp-property-group>
    </jsp-config>
</web-app>

But not getting the proper output. What is wrong over there? Some additional steps are required or what? Please help.

Thanks in advance

EL is not ignored by default. You don't need to configure anything. — JB Nizet, Sep 07 '14 at 21:53
@SotiriosDelimanolis the output should be 25 but its ${10 + 15} — Shashank, Sep 07 '14 at 23:59
@JBNizet I tried that as well. In every case I am getting ${10 + 15}, which should be 25 — Shashank, Sep 08 '14 at 00:00

Change your web.xml to a version that supports EL (2.5+ XSD):

<?xml version="1.0" encoding="ISO-8859-1"?>
<web-app xmlns="http://java.sun.com/xml/ns/j2ee"
     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"
     version="2.5">

</web-app>

or whichever version

<?xml version="1.0" encoding="UTF-8"?>
<web-app 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_3_0.xsd"
          version="3.0">

  </web-app>

ankur-singhals answer worked for me.

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:web="http://xmlns.jcp.org/xml/ns/javaee" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">
    <jsp-config>
        <jsp-property-group>
           <url-pattern>*.jsp</url-pattern>
           <el-ignored>false</el-ignored>
        </jsp-property-group>
    </jsp-config>
</web-app>
