JSP Overview

Scripting elements

• Your JSP code is embedded as a scripting language inside your HTMl code.

  <%  code goes here  %>
  

  begin and end token - this refers to the service method.
  

• Expression tag
  <%= ... %>
  

• Declarations
  <%! ... %> - treated as instance variable in a Servlet (remember that JSP ends up as a servlet). But there is only one - is this a static variable or not??
  

• JSP Comment
  <% // JSP Comment ------  %>
  <!--HTML Comments-->
  

• Here is a short example: ReadNames.jsp and InputData.java.

  Note it's a .txt file so you can look at it. Save them as .jsp and java files if you want to run it.
