ATG - How do I start creating an example Hello World component and module?

Question

I am new to ATG, and I have successfully installed ATG v10.2 with JBoss.
However, since creating components and modules in ATG can be done in different ways, so I would like to know if there is any “Hello World” example for a module and component.

I have already searched on Google, but the various articles submitted on the Internet are not mentioned in detail in detail, in sequential order.
So it will be great if people can describe in detail the steps for beginners, since at least I need to start with one example, which I can later use as a base for other complex ones.

Many thanks to everyone!

Note: -
I also know J2EE and MVC to some extent, where I can submit forms and save user input to the database without any significant problems.
I am also currently studying the ATG Page Developer's Guide.

Answer 1

There are so many concepts in ATG that make it difficult to develop Hello World. Do you want to create one JSP page and expand it as a store of links in trade? Do you want to create a component for viewing in Dyn / Admin? Do you want to create a hello world repository? Depending on what you want to do, the approach to the solution will be different.

Check http://www.asknsay.com/creating-new-atg-project-in-eclipse.html to create a new atg application from scratch using eclipse. It also describes how to deploy it to JBOSS 6.1.
