Now I will show you how to retrieve the data posted from a HTML file in a JSP page. Consider an html page that prompts the user to enter his/her name, let's call it getname.htm. Here is the code of the html file:
<html>
<head>
<title>Enter your name</title>
</head>
<body>
<p> </p>
<form method="POST" action="showname.jsp">
<p><font color="#800000" size="5">Enter your name:</font><input type
="text" name="username" size="20"></p>
<p><input type="submit" value="Submit" name="B1"></p>
</form>
</body>
</html>
The target of form is "showname.jsp", which displays the name entered by the user. To retrieve the value entered by the user we uses the
request.getParameter("username");
code.
Here is the code of "showname.jsp" file:
<%@page contentType="text/html" %>
<!--

<html>
<body>
<p><font size="6">Welcome : <%=request.getParam
eter("username")%></font></p>
</body>
</html>
JavaServer Pages (JSP) lets you separate the dynamic part of your pages from the static HTML. You simply write the regular HTML in the normal manner, using whatever Web-page-building tools you normally use.
ReplyDeleteAmazing blog and very interesting stuff you got here! I definitely learned a lot from reading through some of your earlier posts as well and decided to drop a comment on this one!
ReplyDeleteWhat you're saying is completely true. I know that everybody must say the same thing, but I just think that you put it in a way that everyone can understand. I'm sure you'll reach so many people with what you've got to say.
