STEPS TO EXECUTE JSP
Steps to Execute Jsp |
Example Jsp program
|
|
| step 1 : Create your UserRequest Page |
Create a html page, from that we are going to send request to the server.
For Example : Demo.html
<html>
<head><title>Form Post Example</title></head>
<body>
<center><table border="2">
<tr>
<td>JSP Form Post Example</td>
</tr>
<td>
</center></table>
<center><table border="2">
<form action="nextPageToPost.jsp" action="post">
<center><table border="2">
<tr>
<td align="center"colspan="2"><h4>
Enter data for post to next page <h4></td>
</tr>
<tr>
<td>Enter your name</td>
<td><input type="text" name="name"></td>
</tr>
<tr>
<td>Enter your password</td>
<td><input type="password" name="password"></td>
</tr>
<tr>
<td><b>Sex</b></td>
<td><input type="radio" name="sex" value="Male">Male</td>
<td><input type="radio" name="sex" value="Female">Female</td>
</tr>
<tr>
<td>Are you regular visitor of RoseIndia.net</td>
<td><input type="checkbox" name="check"></td>
</tr>
<tr>
<td>Nationality</td>
<td><select name="nationality" size="1">
<option>India</option>
<option>USA</option>
<option>UK</option>
<option>SRI LANKA</option>
</td>
</tr>
<tr>
<td>Description</td>
</tr>
<tr>
<td><textarea rows="2" name="description" cols="20">
</textarea></td>
</tr>
<tr>
<td><input type="submit" name="submit" value="submit"></td>
<td><input type="reset" name="reset" value="reset"></td>
</tr>
</form>
</table>
</center>
</body>
</html>
The html form tag has the attribute action="nextPageToPost.jsp".
When we press submit button it is going to request the jsp page nextPageToPost.jsp.
|
| step 2 : Create your Jsp Page |
next step is to create one jsp for handle the request from the user. this jsp page may contain the database
connection or your business logic.
For Example : nextPageToPost.jsp
<html>
<head><title>JSP Form Post Example</title></head>
<body>
<center><table border="2">
<tr>
<td><h3>Your message has been posted by using Post Method</h3></td>
</tr>
</center></table>
<center><table border="2" >
<tr>
<td><h4>Name:</h4></td><td><%=request.getParameter("name") %></td>
</tr>
<tr>
<td><h4>Password:</h4></td><td><%=request.getParameter("name") %></td>
</tr>
<tr>
<td><h4>Sex:</h4></td><td><%=request.getParameter("sex")%></td>
</tr>
<tr>
<td><h4>Are you regular <br>visitor of RoseIndia.ne</h4></td><td>
<% if(request.getParameter("check").equals("on"))out.println("Yes"); %></td>
</tr>
<tr>
<td><h4>Nationality</h4></td><td><%=request.getParameter("nationality") %>
</td>
</tr>
<tr>
<td><h4>Description</h4></td><td><%=request.getParameter("description") %>
</td>
</tr>
</center></table>
</body>
</html>
