A Connection to a database can be established from a jsp page by writing the code to establish a connection using a jsp scriptlets.

<%@ page import="java.sql.*" %> <%! String Uname_Text; String Passwd_Text;%> <% Uname_Text=request.getParameter("Uname"); Passwd_Text=request.getParameter("Passwd"); request.setAttribute("Uname",Uname_Text);

try{

    Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
}

    catch(Exception e){ out.println("Driver Detection Failed.");  }

    try{
    Connection conn;
    Statement stm;
    String db = "jdbc:odbc:test";


     conn = DriverManager.getConnection(db,"","");
    System.out.println("****Connected to database***");

stm = conn.createStatement();

    if(Uname_Text=="" || Passwd_Text=="")
    {

        response.sendRedirect("http://localhost:4040/Myjsp/Login_Fail.jsp");
        out.println("Username is empty.");
    }

ResultSet rs = stm.executeQuery("select * from Table1 where UnameTable='"+ UnameText +"' AND PasswdTable='"+PasswdText+"'"); while(rs.next()) {

            out.println(rs.getInt(1) );



            out.println(rs.getString(2) );

            out.println(rs.getString(3) );
            out.println(rs.getString(4) );
            out.println(rs.getString(5) );
            out.println(rs.getString(6) );
               out.println(rs.getString(7)); 

            out.println();
            out.println("");


        }

conn.close();

    }

catch(SQLException e) {

    }

this shows the connection as well as insert command....for update use executeUpdate("upadate command here");
