what are the jsp tags with example?
Answer / sivasubramanian.k
(1)A declaration tag places a variable definition inside
the body of the java servlet class. Static data members may
be defined as well. Also inner classes should be defined
here.
Example:<%! int serverInstanceVariable = 1; %>
Declaration tags also allow methods to be defined.
<%!
/**
* Converts the Object into a string or if
* the Object is null, it returns the empty string.
*/
public String toStringOrBlank( Object obj ){
if(obj != null){
return obj.toString();
}
return "";
}
%>
(2)A scriptlet tag places the contained statements inside
the _jspService() method of the java servlet class.
<% int localStackBasedVariable = 1;
out.println(localStackBasedVariable); %>
(3)An expression tag places an expression to be evaluated
inside the java servlet class. Expressions should not be
terminated with a semi-colon .
<%= "expanded inline data " + 1 %>
(4)Also we can use the following tag to give comments in
jsp:
<%-- give your comments here --%>
