Hi Friend,

Try the following:

import java.io.*;
import java.sql.*;
import java.util.*;
import javax.servlet.*;
import javax.servlet.http.*;

public class Servlet extends HttpServlet {
public void doGet(HttpServletRequest request, HttpServletResponse response)
throws IOException, ServletException {
PrintWriter out = response.getWriter();
out.println("<html><head><script>function deleteRecord(id){var r=confirm('Are you confirm')");
out.println("if (r==true){var reason=prompt('Reason for deleting:')");
out.println("if(reason!=null){");
out.println("window.open('http://localhost:8080/examples/modified/deleteuser.jsp?id='+id+'&&reas='+reason,'mywindow','width=500, height=350,toolbar=no,resizable=yes,menubar=yes')");
out.println("}else{}}}</script></head>");
out.println("<form name='form'>");
out.println("<table border='1'>");
out.println("<tr><th>FirstName</th><th>LastName</th><th>Address</th><th>Email</th></tr>");
Connection con = null;
String url = "jdbc:mysql://localhost:3306/";;;
String db = "test";
String driver = "com.mysql.jdbc.Driver";
String userName ="root";
String password="root";
int sumcount=0;
Statement st;
try {
Class.forName(driver).newInstance();
con = DriverManager.getConnection(url + db, userName, password);
String query = "select * from employee";
st = con.createStatement();
ResultSet rs = st.executeQuery(query);
while (rs.next()) {
out.println("<tr><td>" + rs.getString(2) + "</td><td>"
+ rs.getString(3) + "</td><td>" + rs.getString(4)
+ "</td><td>" + rs.getString(5) + "</td>");
out.println("<td><input type='button' name='edit' value='Delete' style='background-color:red;font-weight:bold;color:#ffffff;' onclick=\"deleteRecord('"
+ rs.getString(1) + "');\"></td></tr>");
}
} catch (Exception e) {
e.printStackTrace();
}
out.println("</table>");
out.println("<form>");
out.println("</html>");
}
}

Thanks
