Change the above program definition implement more
than one textbox and other element on the page pass
them as a parameter and handle
Step 1 : Create HTML Page With All Form Elements Such As TextBox,TextArea,Radio,CheckBox,List With MultipleSelection.
<html>
<head><title>Get Parameter Values</title></head>
<body>
<form action="http://localhost:8080/GetParameters/GetPara" method="post">
<table border="2" align="center" height="50%" width="60%">
<tr align="center">
<td colspan="6" align="center">
<b><u><i>Student FeedBack Form<i><u><b>
</td>
</tr>
<tr align="center">
<td colspan="2">
Name :
</td>
<td colspan="4">
<input type="text" name="txt_name" />
</td>
</tr>
<tr align="center">
<td colspan="2">
Address :
</td>
<td colspan="4">
<textarea rows="5" name="txt_add"></textarea>
</td>
</tr>
<tr align="center">
<td colspan="2">
Sex :
</td>
<td colspan="2">
<input type="radio" name="sex" value="Male" />Male
</td>
<td colspan="2">
<input type="radio" name="sex" value="Female" />Female
</td>
</tr>
<tr align="center">
<td colspan="2">
Hobbies :
</td>
<td>
<input type="checkbox" name="hobbies" value="Volleyball" />VolleyBall
</td>
<td>
<input type="checkbox" name="hobbies" value="Batminton" />Batminton
</td>
<td>
<input type="checkbox" name="hobbies" value="Basketball" />Basketball
</td>
<td>
<input type="checkbox" name="hobbies" value="TableTennies" />TableTennies
</td>
</tr>
<tr align="center">
<td colspan="2">
Subject :
</td>
<td colspan="4">
<select name="subject" multiple>
<option>C
<option>C++
<option>Java
<option>Oracle
<option>Servlet
</select>
</tr>
<tr align="center">
<td colspan="6">
<input type="submit">
<input type="reset">
</td>
</tr>
</table>
</form>
</body>
<html>
Step 2 : Create GetPara.Java which can handle all this form elements and display output in proper html page.
<head><title>Get Parameter Values</title></head>
<body>
<form action="http://localhost:8080/GetParameters/GetPara" method="post">
<table border="2" align="center" height="50%" width="60%">
<tr align="center">
<td colspan="6" align="center">
<b><u><i>Student FeedBack Form<i><u><b>
</td>
</tr>
<tr align="center">
<td colspan="2">
Name :
</td>
<td colspan="4">
<input type="text" name="txt_name" />
</td>
</tr>
<tr align="center">
<td colspan="2">
Address :
</td>
<td colspan="4">
<textarea rows="5" name="txt_add"></textarea>
</td>
</tr>
<tr align="center">
<td colspan="2">
Sex :
</td>
<td colspan="2">
<input type="radio" name="sex" value="Male" />Male
</td>
<td colspan="2">
<input type="radio" name="sex" value="Female" />Female
</td>
</tr>
<tr align="center">
<td colspan="2">
Hobbies :
</td>
<td>
<input type="checkbox" name="hobbies" value="Volleyball" />VolleyBall
</td>
<td>
<input type="checkbox" name="hobbies" value="Batminton" />Batminton
</td>
<td>
<input type="checkbox" name="hobbies" value="Basketball" />Basketball
</td>
<td>
<input type="checkbox" name="hobbies" value="TableTennies" />TableTennies
</td>
</tr>
<tr align="center">
<td colspan="2">
Subject :
</td>
<td colspan="4">
<select name="subject" multiple>
<option>C
<option>C++
<option>Java
<option>Oracle
<option>Servlet
</select>
</tr>
<tr align="center">
<td colspan="6">
<input type="submit">
<input type="reset">
</td>
</tr>
</table>
</form>
</body>

Step 3: Create Web.INF file for Servlet Mapping.
<?xml version="1.0" encoding="ISO-8859-1"?>
<web-app>
<servlet>
<servlet-name>GetParameters</servlet-name>
<servlet-class>pack2.GetPara</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>GetParameters</servlet-name>
<url-pattern>/GetPara</url-pattern>
</servlet-mapping>
</web-app>
<web-app>
<servlet>
<servlet-name>GetParameters</servlet-name>
<servlet-class>pack2.GetPara</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>GetParameters</servlet-name>
<url-pattern>/GetPara</url-pattern>
</servlet-mapping>
</web-app>
