Taking TOTD #121 forward, this blog explains how to create a JPA Persistence Unit for a MySQL sample database and package it as a library. This JAR file can then be easily included in other web applications.

Lets get started!

Configure GlassFish for using the MySQL sample database (sakila) as described in TOTD #121.

Add the GlassFish instance in NetBeans IDE using "Services" panel.

Create JPA entities using NetBeans IDE.

This blog clearly explains how to configure the MySQL sample database (sakila) with GlassFish. Even though the instructions use a specific database but should work for other databases (such as Oracle, JavaDB, PostgreSQL, and others) as well. The second half of the blog provide specific syntax for the Oracle sample database.

Download sakila sample database and unzip the archive.

Install the database as described here - basically load and run "sakila-schema.sql" and "sakila-data.sql" extracted from the archive.

Create a new MySQL user account using MySQL CLI Admin and assign the privileges

This entry is a follow up to TOTD #95 and shows how to use the recent integrations of JSR 299 in GlassFish v3 to convert a JSF managed bean to a JSR 299 bean (aka Web Beans). The TOTD #95 describes a simple Java EE 6 web application that uses Java Server Faces 2.0 components for displaying the results of a database query conducted by EJB 3.1 and JPA 2.0 classes.

TOTD #93 showed how to get started with Java EE 6 using NetBeans 6.8 M1 and GlassFish v3 by building a simple Servlet 3.0 + JPA 2.0 web application. TOTD #94 built upon it by using Java Server Faces 2 instead of Servlet 3.0 for displaying the results. However we are still using a POJO for all the database interactions. This works fine if we are only reading values from the database but that's not how a typical web application behaves. The web application would typically perform all CRUD operations. More typically they like to perform one or more CRUD operations within the context of a

TOTD #93 showed how to get started with Java EE 6 using NetBeans 6.8 M1 and GlassFish v3 by building a simple Servlet 3.0 + JPA 2.0 web application. JPA 2.0 + Eclipselink was used for the database connectivity and Servlet 3.0 was used for displaying the results to the user. The sample demonstrated how the two technologies can be mixed to create a simple web application. But Servlets are meant for server-side processing rather than displaying the results to end user. JavaServer Faces 2 (another new specification in Java EE 6) is designed to fulfill that purpose.

NetBeans 6.8 M1 introduces support for creating Java EE 6 applications ... cool!

This Tip Of The Day (TOTD) shows how to create a simple web application using JPA 2.0 and Servlet 3.0 and deploy on GlassFish v3 latest promoted build (58 as of this writing). If you can work with the one week older build then NetBeans 6.8 M1 comes pre-bundled with 57. The example below should work fine on that as well.

Create the database, table, and populate some data into it as shown below:

~/tools/glassfish/v3/58/glassfishv3/bin >sudo mysql --user root

EclipseLink JPA replaces TopLink Essentials as the JPA implementation in GlassFish v3. One of the benefits of using EclipseLink is that it provides efficient pagination support for the MySQL database by generating native SQL statements such as "SELECT ... FROM <table> LIMIT <offset>, <rowcount>".

The MySQL LIMIT clause definition says:

The LIMIT clause can be used to constrain the number of rows returned by the SELECT statement. LIMIT takes one or two numeric arguments, which must both be non-negative integer constants

TOTD #9 explained how to configure JDBC connection pooling for Rails application deployed on GlassFish v2. There are several benefits of using using the JDBC connection pools:

• No need to create a new database connection for each Rails instance.
• No need to specify your password in database.yml or create a hack to hide it.
• No garbage collection of connection after each use.

And because of the above mentioned (and other reasons) an improved application performance, scalability and efficiency.
The only way to deploy a Rails application on GlassFish v2 is to create a WAR file using Warbler. That's a
