Just a minute Nalla..

I think, you don't have the EL (Expression Language) jars in your classpath. Isn't it?

Servlet:

JSP:
HTML:
web.xml:

thanks kushal

Nalla

Add el-api.jar and el-impl.jar to your classpath..

It should work..

Khushhal

Kushal,

thanks

Nalla

Add el-api.jar and el-impl.jar to your classpath..

At least el-api.jar. And see, whether it works..

Khushhal

Nalla,

You have to specify them in your system as Enviroment user variable CLASSPATH.
Don't have to copy them to C:\apache-tomcat-6.0.13\lib.
They will be already at that location.
