New Video Series: Essential EGL+Batch

Starting out with EGL? Don't try to learn too much too soon. This video series is intentionally limited to the very simple EGL+Batch model. In this model, you run a program in a runnable Java Archive from a command line. You only need a Java Virtual Machine, such as provided by Java Runtime Environment 6.

With this model, you can do important production work, such as import/export information into a JDBC-compatible database, such as DB2, SQL Server or Oracle. You can validate existing data. You can write, debug and test business logic in a library before it is used by a web service provider.

With this model, you can learn the development tools, such as the IDE, editor and generator. You can learn the most important features of the the language, such as built-in types, parts, control structures, records, arrays, dictionaries, delegates and more. You can learn to work with the Eclipse debugger.

At first, you do not need to learn additional technologies. Once you have learned the basics, you can then go on to learn more complex models, such as EGL Rich UI, web service provider, EGL+JSF. You can go on to learn the complexities of the full JEE application server.

This tutorial features EGL Development Tools (EDT), an Eclipse project. We'll use version 0.8. Install EDT on Linux or Windows. In lesson 01, create a basic project, create a package, write a program, run a program, debug a program, create a runnable Java archive, run a program from a command line. In lesson 02, write a library, learn about the built-in type called string, learn about the const and private keywords, use the debugger to find and fix a bug.

Thanks for watching!
