In this tutorial, a Java web application communicates directly with a My SQL database using the Java Database Connectivity API.Essentially, it is the My SQL Connector/J JDBC Driver that enables communication between the Java code understood by the application server (the Glass Fish server), and any content in SQL, the language understood by the database server (My SQL).The table data used in that tutorial is contained in and is also required for this tutorial.This SQL file creates two tables, , in which a client communicates directly with a server.However, there are times when you do want to update data. If you are using a dataset, you can write changes to the dataset and then call the data adapter to send changes from the dataset to the database.
If you downloaded the Glass Fish server separately and need help registering it in Net Beans IDE, see Registering a Glass Fish Server Instance in the IDE's Help Contents (F1).
String update Table SQL = "UPDATE DBUSER SET USERNAME = ?
This document demonstrates how to set up a connection to Java DB database in Net Beans IDE.
For more information on Java DB database, consult the official documentation.
Contents If you have the Glass Fish Server registered in your Net Beans IDE installation, Java DB will already be registered for you.
