    First of all, the above page doesn’t even use the JSTL. It uses the JSP EL.

    And I assume you expect to see dollar: "Welcome" printed, but that won’t happen, because the JSP EL doesn’t print values of local variables. It prints the value of attributes.

    Change your code to 

    <% pageContext.setAttribute("var1", "Welcome"); %>

    or, better, to

    <c:set var="var1" value="Welcome"/>

    and you’ll see the expected output.
