Expression tag in JSP
Expression is a replacement for out.println();. Notice the semicolon carefully after out.println();. So we should not use semi colon at the end of expression. All the expressions inside the JSP will be placed inside the jspService() method. Expressions cannot be used inside a scriptlet. Syntax of JSP expression tag is:
<%= "Statement" %>
The code is a short cut form of the below code.
<%
out.println("Statement");
%>
