Run J2EE Deployathon Online!

Japanese Version of J2EE Deployathon Online!

Introduction

J2EE Deployathon Online! is a demonstration of application portability across servers that comply with the Java 2 Platform, Enterprise Edition (J2EE^TM) specifications. The J2EE platform defines the standard for developing multitier enterprise applications. It builds on the base of Java 2 Platform, Standard Edition and adds enterprise technologies such as EJB technology, Java Naming and Directory Interface (JNDI), and JDBC. The J2EE platform provides "write once, run anywhere" capability for Java components on the server.

If you're new to J2EE, a good place to learn about its capabilities is in J2EE Blueprints Digest. You can find other J2EE learning materials in the J2EE Technology Center Home Page

One of the important deliverables for the J2EE platform is the J2EE Blueprints. The J2EE Blueprints provide an integrated set of documentation and examples that describe and illustrate the best practices for developing and deploying applications using the J2EE platform. Accompanying the Blueprints is a sample application that illustrates the capabilities of the J2EE platform. The sample application, called Java Pet Store, models an e-commerce application for ordering pets. This is the application that is used in J2EE Deployathon Online! You'll be able to run this application in various J2EE-compliant servers, and by doing that you'll see that the application runs with little or no change. In other words, you'll validate J2EE's promise of portability across servers that implement the J2EE specifications.

Why is Portability Important?

Portability is one of the most attractive aspects of the Java programming language. Applications coded in the Java language can run unchanged in many different types of stand-alone or client operating environments. J2EE extends the portability benefits of the Java language to the enterprise. It allows you to run applications across different types of J2EE-compliant servers. Given the large investment most businesses have in client-server applications, J2EE can save companies a lot of development time and money. With J2EE's portability features, there's little or no need to rewrite code for different servers.

Java Pet Store

Java Pet Store is a sample application that demonstrates the capabilities of the J2EE platform. It's an e-commerce application that enables customers to purchase pets on the Web. Customers can scan the pet store's inventory of pets, add one or more items to their "shopping cart," and then "check out" by confirming the order and supplying billing and shipping information.

Java Pet Store illustrates many of the features of J2EE, such as JavaServer Pages (JSP^TM) and EJB technology. It is also a good example of J2EE application design, one that follows the best practices described in the J2EE Blueprints. You can examine the source code for the application; it's available with the Java Pet Store download. You download the application as one of the steps when you run J2EE Deployathon Online!

Run J2EE Deployathon Online!

1. Select a J2EE server product from the J2EE Deployathon Online! server list in the table below. This links you to the instructions for setting up and running the Java Pet Store application in the server and platform you select. The instructions cover steps such as downloading, installing, and configuring the server and the application, and describes how to start the application.

   Some of the listed J2EE server products allow you to run the Java Pet Store application immediately, that is, you don't have to do any prior setting up to run the application. These products have the entry "run it now" in the "Live Demo" column. Click on "run it now" to immediately run the Java Pet Store application in that server and platform.

2. After you sucessfully run Java Pet Store in the server of your choice, try running the application in another J2EE server. Select another J2EE server product from the J2EE server list, follow the instructions for setting up and running Java Pet Store in this new server, then start the application. Or run the live demo if available. Notice that the code runs with little or no change. Some changes are required to the source code for some J2EE servers. The changes are described in the instructions for that server. These changes are relatively minor and occur mainly in the area of security. One of the aims of J2EE Deployathon Online! is to continue to improve portability so that no changes are required to J2EE application source code across J2EE servers.

J2EE Deployathon Online! Server List

Select a highlighted server; these servers are enabled for the Java Pet Store 1.1.2 application. Listed servers that are not highlighted will be enabled for the Java Pet Store 1.1.2 application soon.

A Note About J2EE Products

Only products that have been tested successfully against the compatibility test suite (CTS) provided with J2EE can be called J2EE products. For a list of J2EE products see Java 2 Platform, Enterprise Edition Compatibility. However, all of the products in the J2EE Deployathon Online! server list are believed to reliably implement the J2EE specifications. In fact successfully running Java Pet Store with a server in the list suggests that the server will run successfully against the CTS.

Running the application with the server does not substitute for actually testing the server against the CTS. J2EE Deployathon Online! is not intended to guarantee the portability features of a J2EE product or solution. J2EE Deployathon Online! is designed to demonstrate the portability built into J2EE and to help developers produce portable J2EE components and applications.
