AJAX Tricks and Prototype

Netbeans and Derby and Ajax

  1. Add the derby.jar library to your project. It was installed under glassfish-v2/javadb/lib.
  2. Here is sample code for the connection:

    package edu.sc.cse;
    import org.apache.derby.jdbc.*;
    import java.sql.Connection;
    import java.sql.DriverManager;
    public class DatabaseConnector {
        public static Connection getConnection() {
            Connection con = null;
            String driver = "org.apache.derby.jdbc.EmbeddedDriver";
            try {
            } catch (Exception e) {
                System.out.println("Failed to load mySQL driver.");
                return null;
            try {
                //AJAX is the database name. 
                //This is for empty username and password
                //Otherwise append ?username=jmvidal&password=usc
                con = DriverManager.getConnection("jdbc:derby://localhost:1527/AJAX");
              } catch (Exception e) {
              return con;
  3. To import or export a whole table, like zipcodes.del use:
    /*To import my zipcodes.del table */
    /* To export a table */
  4. To delete all rows use delete from "TABLENAME"
  5. To insert use INSERT INTO TABLE (USERNAME,PASSWORD) VALUES ('jmvidal','usc')
  6. When building statments in JDBC, do not add a ; at the end.
