Thread: sample JSP code connecting to PostgreSQL

sample JSP code connecting to PostgreSQL

From

Hi folks,

I'm wondering if anybody would be pleasant enough to give me a complete
script containing JSP code that makes a simple connection to a
PostgreSQL database, retrieves data and dumps to screen.

I must be dumb not to be able to find this information anywhere on the
net. :(

Regards,
Roj

I just use Dreamweaver MX.

Or you can build your JSP in NetBeans / SunOne Studio which are free
tools.

    public static void main(String args[])
    {


        String url = "jdbc:postgresql://localhost/database";
        Connection con;
        ResultSet rs;
        String s;
        String sqlstr = "SELECT f1, f2, f3 FROM table";

        try
        {
            Class.forName("org.postgresql.Driver");
        }
        catch(java.lang.ClassNotFoundException e)
        {
            System.err.print("ClassNotFoundException: ");
            System.err.println(e.getMessage());
        }

        try
        {
            con = DriverManager.getConnection(url,"postgres", "");

            st = con.createStatement();
            rs = st.executeQuery(sqlstr);

            System.out.println("Rows are :");
            while(rs.next())
            {
                s = rs.getString(1);
                  System.out.println(s);
            }
            System.out.println(mn.gname());
                 rs.close();
            st.close();
            con.close();

        }
        catch(SQLException ex)
        {
            System.err.println("SQLException: " + ex.getMessage());
        }

    }

If you are comfortable with tags, you shall consider using JSTL sql tags to do the job for you instead of using
scriptlet.
