JSP Comments

Comments in JSP:-
-->Compiler /Interpreter doesn't take commented code for compilation /Interpretation, so the commented code doesn't participate in execution
JSP supports 3 types of comments:-
a.)HTML comments /Template text comments/ Output comments
  1. Syn:- <!---text--->
-->Recognized by html interpreter of browser
b.)JSP comments /Hidden comments
  1. Syn:- <%--text--%>
-->JSP page compiler recognize these comments
c.)Java comments /Scripting comments
  1. Syn:-
  2. //-->For single line
  3. /*--
  4. -----*/-->For multiple line
-->Java compiler(java) recognize these comments
-->In Eclipse IDE JES class for first.jsp comes in our(workspace)folder/.metadata/.plugins/.org eclipse
Comments
(1)JSP comment<%--%>
(2)Java comment(// or /*--*/)
(3)HTML comments(<!--->
JES Source Code
(1)No
(2)Yes
(3)Yes
In JES compiled code
(1)No
(2)No
(3)Yes
In the code going to browser
(1)No
(2)No
(3)Yes
Output
(1)No
(2)No
(3)No
-->Jsp comments are not visible in any phase at jsp execution so there are called hidden component
-->Html comments will not be recognised in the server they go to browser along with the response, so there are called output comments
-->We can use page directive tag to import the packages in our jsp component
  1. <%@page import="java.util.*, java.net.*"%>
-->In Eclipse IDE we can use Ctrl+Shift+c to put appropriate comments in appropriate lines
