Part 3 of the GlassFish and MySQL Series Now Available
The article GlassFish and MySQL, Part 3: Creating and Using a Web Service is now available. This article is the third in a series of articles about the use of MySQL with GlassFish. Ive collaborated on these articles with Java technology evangelist Carol McDonald. In Part 3, you'll learn how easy it is to convert the controller layer of the web application introduced in Part 2, that is, the layer of the application that performs the create, read, update, and delete (CRUD) operations -- into a SOAP-based web service. You'll also learn how to create a client for the web service.

GlassFish and MySQL: The Series
With more than 100 million downloads, MySQL is the world's most popular open-source database. MySQL's popularity is indicative of the growing adoption of open-source software. Developers are using open-source software because it offers them a reliable and low-cost alternative for developing their applications. This adoption trend extends to middleware too. For example, open-source servers are replacing proprietary servers in many enterprises. Case in point: GlassFish, an open-source, enterprise-quality, Java EE 5-compliant application server, enjoys significant popularity. With more than seven million downloads since its release in May 2005 and more than half a million downloads a month, GlassFish has a widespread and growing community of users.
Read the article GlassFish and MySQL, Part 1: A Perfect Combination for Web Applications and learn about the advantages of using MySQL with GlassFish and why the combination is a perfect choice for developing and deploying web applications.
This article is the first in a series of articles about the use MySQL with GlassFish. The second article in the series, GlassFish and MySQL, Part 2: Building a CRUD Web Application With Data Persistence, shows you how to use the NetBeans IDE with GlassFish and MySQL to build a create, read, update, and delete (CRUD) web application that accesses persistent data.

Enterprise Tech Tip: Configuring JSON for RESTful Web Services in Jersey 1.0
There's a lot of interest in the developer community in RESTful web services. That's because the Representational State Transfer (REST) approach presents a relatively simple and flexible way of building and communicating with web services. Message exchanges with a RESTful web service can be conducted in any format, including JavaScript Object Notation (JSON). Because of its simple text format, JSON provides a good alternative to other message interchange formats such as XML and is particularly attractive as a meassage interchange format for RESTful web services.
This tip shows you how to build a Jersey-based web application that returns information in JSON format. Jersey is an open-source, production-ready reference implementation of JAX-RS, the Java API for RESTful Web Services (JSR-311).
See the tip Configuring JSON for RESTful Web Services in Jersey 1.0.

Enterprise Tech Tip: Composite UI Components in JSF 2.0 -- Part 2
As I mentioned in my previous post, this two-part Tech Tip introduces a powerful new feature in JavaServer Faces (JSF) 2.0 technology: composite user interface (UI) components. Part 1 of the tip shows you how create a composite UI component and use it in a web application.
Part 2 is now available. It shows you how to add functionality (through attached validators, converters, action listeners, and value change listeners) to the composite component you created.
See Composite UI Components in JSF 2.0 -- Part 1 and Composite UI Components in JSF 2.0 -- Part 2.

Enterprise Tech Tip: Composite UI Components in JSF 2.0 -- Part 1
This Tech Tip introduces a powerful new feature in JavaServer Faces (JSF) 2.0 technology: composite user interface (UI) components. This feature allows you to turn any collection of page markup into a JSF UI component -- with attached validators, converters, action listeners, and value change listeners -- for use by page authors.
This tip is presented in two parts. In the first part, you'll learn you how create a composite UI component and use it in a web application. In the second part, which will be published in the next issue of the Enterprise Tech Tips, you'll learn how to add functionality to the composite component.
See Composite UI Components in JSF 2.0 -- Part 1.

RESTful Web Services and Comet
Comet is a programming technique that enables a server to push data to client browsers. The technique is often referred to as "reverse Ajax". RESTful web services are web services built using the Representational State Transfer (REST) architectural style. RESTful web services have come into widespread use because they tend to be lighter weight than SOAP-based web services.
Java Technology Evangelist, Carol McDonald, and Sun Staff Writer Rick Palkovic have written an interesting article that shows how RESTful web services with Comet can be used to produce an application in which the actions of one user affect the pages seen by other users. See RESTful Web Services and Comet.

JavaFX Learning Curve Journal Updates
In August and September 2007, the Sun Developer Network staff started a Learning Curve Journal, a series designed to help users get started with the JavaFX Script programming language (shortened to JavaFX Script hereafter). A number of significant advances have been made to the language since then. Perhaps most important is the availability of a compiler-based version of JavaFX Script, which replaces the earlier interpreter-based version of the language. The Learning Curve Journal described the use of the interpreter-based version of the language. The Learning Curve Journal has been updated to show you how to use the compiler-based version of the language. Other changes have been made to make the articles current.
Part 1: Exploring JavaFX Script gets you started with a simple JavaFX program, that is, a simple program written in the JavaFX Script language. You'll learn how to set up your environment for programming in JavaFX Script and how to build and run a JavaFX program.
Part 2: Declarative User Interfaces focuses on the declarative style of coding enabled by JavaFX Script. You'll see how this style can make the code for a graphical application simpler and more intuitive.
Part 3: JavaFX Script Functions shows you how to use JavaFX Script functions to implement actions in a Java FX program.
Part 4: Accessing a Web Service demonstrates how to use JavaFX Script to access a web service. In doing that, it also shows how easy it is to access Java technology classes, such as Swing classes, from JavaFX Script.

Enterprise Tech Tip: Using P6Spy and the GlassFish Connection Pool to Trace Database Operations
Detecting performance bottlenecks is an important task in optimizing database operations in an application. One way to do that is to trace the database operations of the application. This information can help you fine tune the database calls that the application makes and in this way improve the application's performance. In this Tech Tip, Sun engineer Jagadish Ramu demonstrates how to use a tool called P6Spy to trace the database requests issued by an application running with the GlassFish v2 application server. Specifically, you'll learn how to trace SQL statements from an application that uses GlassFish's JDBC Connection Pool. It's all covered in the tip Using P6Spy and the GlassFish Connection Pool to Trace Database Operations.
