try this :

<% String [ ] myList = {"gadar","lagaan","DCH","ghayal"};
request.setAttribute("myList", myList);
%>


value of items attribute in c:forEach is an attribute set by the request object.

kaju:

The problem with your code is mainly with the attribute items in the <c:forEach>. You are using the EL expression ${myList}. This means that an attribute should exist in one of the scopes (page, request, session or application).

In your code you only declared a local variable String[] called "myList". Thus, you must set the attribute in any one of the scopes.
pageContext.setAttribute("myList", myList)
or
request.setAttribute("myList", myList)
or
session.setAttribute("myList", myList)
or
application.setAttribute("myList", myList)
or any one of the following:
pageContext.setAttribute("myList", myList, pageContext.REQUEST_SCOPE);
pageContext.setAttribute("myList", myList, pageContext.SESSION_SCOPE);
pageContext.setAttribute("myList", myList, pageContext.APPLICATION_SCOPE);
