Visualize with Rational Software Modeler: UML 2.0 modeling

Using easy-to-follow, step-by-step instructions, this tutorial lets you sample some of the visual UML 2.0 modeling capabilities. By the end, you'll know how to create a variety of different UML 2.0 diagrams, import existing modeling projects, and edit models.

A Quick Start to developing applications with Enterprise Generation Language (EGL)

Using easy-to-follow, step-by-step instructions, this tutorial introduces EGL from a "how to" perspective in the context of developing business applications that process dynamic content on the Internet. It assumes no prior usage of Java and covers EGL terms, concepts, vocabulary and project structure, files and artifacts from the very beginning. When you finish, you will have built a small prototype application consisting of 20 or so web pages. You will have coded working examples using over 80% of the EGL language capabilities, including creating and consuming Web Services, calling Java classes and other reasonably advanced techniques. Note that three viewlets are available to start you off. You might want to download them as well. They are: basicjsp.zip, allcustomers.zip and updatepage.zip.

Persist arbitrary data to Apache Derby

You can quickly and easily persist simple data to Apache Derby by taking advantage of Java dynamic proxies. In this tutorial, write a persistence API that you can integrate into any database-powered Java application. You use the API to store an application's configuration information and to notify the application when configuration items change.

User annotations in Ajax

The ability to add notes and comments to your Web site can be a powerful and attractive feature for users. This tutorial demonstrates how to implement an Asynchronous JavaScript and XML (AJAX)-based user annotation system in the form of yellow sticky notes that sit on top of regular Web page content. The only additional, required configuration is a back-end Perl script that stores the annotations

Building a grid using Web services standards, Part 3

In this "Building a grid using Web services standards" tutorial series, we're building a movie grid application using standard Web services. Building a grid is a complex process, but development and deployment are easier if you stick to accepted standards. With standard Web services, you can take advantage of technology like security, reliable messaging, and monitoring services -- plus, you gain compatibility with other grids and improved compatibility with other platforms.
