I have declared an application context parameter as below in web.xml

<web-app>
<context-param>
<param-name>email</param-name>
<param-value>sramprasad@gmail.com</param-value>
</context-param>
</web-app>

I am able to access the param and print using

<%=application.getInitParameter("email")%>

In the same lines, can anyone tell me how to access and print using EL.

You can use EL implicit object "initParam" to retrieve the value like this in jsp

or you can use also
the following kind of EL
syntax ..

${initParam["email"]} or
${initParam['email']}

Thanks for your replies.

Actually, I had a problem with EL.

when u have <%@page isELIgnored="false"%> then u can't use

You will get an error "attribute value does not accept any expressions"

Hope the above observation is usefull to all.

Mr Ram your observation is not RIGHT !!!
Try below code and let me know what you see in your browser.

In your web.xml file

P:S I have to give "space" between "<c: out" tag otherwise you will see some nice image

. So remove the same in your jsp.

Thanks Ashley.
Yesterday, I made a mistake in the <c: out> tag.

Thank you for correcting me.

If you send is by car it's a shipment, but if by ship it's cargo. This tiny ad told me:
