this would search for attribute in pageContext for name "employee.name.firstName".

Try using <jsp:getProperty> method or use Expression Language for same

You should no longer be using scriptlets and scriptlet expressions. They have been discredited for almost 10 years now.

Use the JSTL and EL instead.
