Answer 2

Answer:

Concept:

JSP Expression Language (EL) is useful and is evaluated in JSP pages by default since Servlet 2.4. However, sometimes we would not want to evaluate EL, e.g. keep everything in the pattern ${..} looks as it is. In JSP, it’s possible to deactivate EL evaluation for a single JSP page for a group of JSPs

Explanation:

Default EL Evaluation Mode

EL evaluation is enabled by default if the Servlet version specified in the web deployment descriptor file (web.xml) is 2.4 or later, for example:

               <web-app xmlns:xsi=….. version=”3.0”>

And EL expressions are ignored if the Servlet version is 2.3 or lower:

                <web-app xmlns:xsi=….. version=”2.3”>

Today the latest version of Servlet is 3.0, so it’s likely that every Java web application has EL evaluation enabled by default.

Deactivating EL evaluation for a single JSP page

We can deactivate EL evaluation in a single JSP page by specifying the attribute isELIgnored=”true” in the page directive as follows:

                    <%@ page isELIgnored="true" %>
