I am trying to create a web application,where we have a html page with table containing rows and a submit button. When clicked on the submit button the table will be displayed .So I need to use servlets, But I am not sure where I can write the onclick button option and how to relate that to servlet class. Thanks in advance
Here are my files: //Table.java ----- servlet
import java.io.IOException;
import java.io.PrintWriter;
import javax.servlet.RequestDispatcher;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.sql.*;
class Table extends HttpServlet {
public void doPost (HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException{
response.setContentType("text/html");
PrintWriter out = response.getWriter();
try{
RequestDispatcher rd = request.getRequestDispatcher("index.html");
rd.forward(request, response);
}
finally{
out.close();
}
}
}
Index.html:
<!DOCTYPE HTML>
<html>
<head>
<h1>Student</h1>
</head>
<body>
<table border="1">
<tr>
<th>ID</th>
<th>Name</th>
<th>Major</th>
<th>GPA</th>

</tr>
<td valign="bottom" align="right">
<form><input type = "submit" name = "submit" value = "submit"></form>
</td>
</body>
</html>
web.xml page:
<servlet>
<servlet-name>xyz</servlet-name>
<servlet-class>Table</servlet-class>
</servlet>
<servlet-mapping>
