Hi Friend,
Try the following code:
1)form.jsp:
<html>
<form method="post" action="../ServletExample">
<table>
<tr><td>TextBox1</td><td><input type="text" name="t1"></td></tr>
<tr><td>TextBox2</td><td><input type="text" name="t1"></td></tr>
<tr><td>TextBox3</td><td><input type="text" name="t1"></td></tr>
<tr><td>TextBox4</td><td><input type="text" name="t1"></td></tr>
<tr><td><input type="submit" value="Submit"></td></tr>
</table>
</form>
</html>
2)ServletExample.java:
import java.io.*;
import javax.servlet.*;
import javax.servlet.http.*;
public class ServletExample extends HttpServlet{
public void doPost(HttpServletRequest req,HttpServletResponse res)throws ServletException,IOException{
res.setContentType("text/html");
PrintWriter out=res.getWriter();
String values[]=req.getParameterValues("t1");
for(int i=0;i<values.length;i++){
out.println(values[i]+"<br>");
}
}
}
Thanks
