enabling el in jsp [duplicate]

Answer 1

Your web.xml file looks fine for JSP 2.0. If you are having problems accessing EL on specific pages try adding the following to the top of the individual JSP page:

<%@ page isELIgnored="false" %>

Since you are using JSP 2.0 I think that EL is ignored by default so you can can add the following to your web.xml to enable it for all pages:

<jsp-config>
  <jsp-property-group>
    <url-pattern>*.jsp</url-pattern>
    <el-enabled>true</el-enabled>
    <scripting-enabled>true</scripting-enabled>
  </jsp-property-group>
</jsp-config>

Answer 3

With the web.xml below scriplets and expression languages will be enabled on pages jsp explicitly:

WEB-INF\web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" version="2.5">
  <jsp-config>
    <jsp-property-group>
        <url-pattern>*.jsp</url-pattern>
        <el-ignored>false</el-ignored>
        <scripting-invalid>false</scripting-invalid>
    </jsp-property-group>
  </jsp-config>
</web-app>
