Writing Method in JSP an Example

We can write functions or methods into JSP using the Declaratives tags..

because any function that is defined in the declaratives tags are class level and

can be called anywhere in the JSP page.

Syntax of Declaratives tags:

<%!
//Write your method or function in between the declaratives tags
%>

a simple example of JSP Functions
<%@ page contentType="text/html;charset=ISO-8859-1"%>

<%!public String exampleName(){
return "RoseIndia JSP Method Example";
}
%>

<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<title>Method in JSP</title>
</head>
<body>
<%=exampleName()%>
</body>
</html>

See the given simple button Example to submit or print the data from database using JSP.
http://www.roseindia.net/jsp/submit-comments-database.shtml

It'll be better if can post your query with the code and problems that you are facing during development.
