Get Method of the Form In JSP

     

This section provides you the best illustration of the get method of the form in JSP. The HTTP get method sends data to the server. In your JSP application, the get method of the form carries the form data and sends to the Bean, Servlet or any type of the server side component that uses the form data carried by the get method. Whenever you use the get method to carry data for sending to the server side component, is shown in the URL as the value of all the form control separately.

This method carries the form data from the server while the post method posts the form data there (to the server). All the fields and the values of these components are separated by the "&" character in the URL.

Here is the JSP code of the example:

 

<html>
	<head><title>Using Get Method in JSP Form.</title></head>
	<body>
		<form method="get">
			<table border="0" cellpadding="0" 
cellspacing="0">
				<tr>
					<td>Enter your name:
 </td>
					<td><input type="text"
 size="20" name="txtName" /></td>
				</tr>
				<tr>
					<td>&nbsp;</td>
					<td><input type="submit"
 name="B1" value="Submit" /><input type="reset" name="B2" value=
"Reset" /></td>
				</tr>
			</table>
		</form>
		<%
			if(request.getParameter("txtName") !=
 null){
				if(request.getParameter("
txtName").equals(""))
					out.println("<html>
<font color=red>Please enter your name.</font></html>");
				else
					out.println("Your 
username is: " + request.getParameter("txtName"));
			}
		%>
	</body>
</html>
