A new step-by-step tutorial (Create a mortgage portal with EGL Rich UI) has been added to the Rational Business Developer (RBD) version 8 Information Center, and will also appear automatically in the RBD help if you have the option to "include remote help" enabled in your preferences (Windows > Preferences > Help > Content). This tutorial was originally written for EGL Community Edition, but has been updated for version 8. It shows the basic steps for creating a rich, multi-tier application with EGL.

This tutorial is great for anyone new to EGL or just wanting to learn how to use some of the new features in version 8!

Here is what the resulting application (that you create) will look like (well, assuming you do everything right) ...



This tutorial demonstrates the following concepts:

• Developing a portal-style web UI
• Creating a web service with EGL and invoking from a web application
• Enhancing the UI with rich widgets, including currency text fields and pie charts
• Integrating third-party JavaScript widgets, such as a Google map widget
• Invoking a third-party web service
• Packaging the application as a standard web application (.war) and deploying
• Passing information around the application using EGL's infobus

The tutorial also highlights some of the new features in version 8.0.1:

• EGL Data View (drag-and-drop a record to create a UI)
• GridLayout widget (easily drag/drop and position widgets)
• Dojo widgets
• New EGL Record wizard (create EGL record definitions from an existing third-party JSON or XML-based web services)
• FormManager (model-view-controller and validation)
  

For more information about these features, refer to the help or check out the what's new article.

Note: this tutorial pre-reqs Rational Business Developer version 8 or Rational Developer for z with EGL version 8. Both are available as a 60-day trial.
