EL in jsp

What version of JSP ru using??

see this <%@ page isELIgnored ="true|false" %>

because the pattern that identifies EL expressions--${ }--was not reserved in the JSP specifications before JSP 2.0, there may be applications where such a pattern is intended to pass through verbatim. To prevent the pattern from being evaluated, you can deactivate EL evaluation.

To deactivate the evaluation of EL expressions, you specify the isELIgnored attribute of the page directive:

<%@ page isELIgnored ="true|false" %>

The valid values of this attribute are true and false. If it is true, EL expressions are ignored when they appear in static text or tag attributes. If it is false, EL expressions are evaluated by the container.

The default value varies depending on the version of the web application deployment descriptor. The default mode for JSP pages delivered using a Servlet 2.3 or earlier descriptor is to ignore EL expressions; this provides backward compatibility. The default mode for JSP pages delivered with a Servlet 2.4 descriptor is to evaluate EL expressions; this automatically provides the default that most applications want. You can also deactivate EL expression evaluation for a group of JSP pages.
