Mapping types of ATG repository

The mapping a repository is very important in a database design, because if it is not done correctly, you may not be able to set-up your repository XML correctly, and if this is not done, you'll never be able to figure out what went wrong, or why your repository is functioning properly. Let us pick up various mapping topics and learn when to use them.

Another references about ATG

During my research to solve problems or get content for our blog ATG, some sites/blogs caught my attention and deserved to be saved for future reference.

Below are being sharing a list of links collected with good contents about ATG:

Basic concepts about ATG.

This post is for the ATG beginners to get some basic overview about ATG.

At the framework level, ATG is a java based application platform for hosting web-based applications, as well as RMI accessible business components, with an ORM layer, a component container, an MVC framework, and a set of tag libraries for JSP.

RQL - Repository Query Language

Repository Query Language

DAF provides a generic language for formulating queries. Because these queries must map to any repository implementation, the queries cannot be expressed in terms of any one back-end implementation (such as SQL or LDAP query syntax). Instead, the queries must be expressed in Repository Query Language (RQL), and the individual repository connectors are responsible for translating those queries into the query syntax expected by the underlying data store.

FormHandlers ATG

What is Formhandler?

In many web applications users input are taken from the forms. A form may need to handle user input in a variety of formats, check input for validity, handle errors, and pass input to a servlet for processing or to a database for storage.  ATG java classes that process these forms are none other than Formhandlers.

A Formhandler is just like any other component. They can exist out-of-the box, and can be used as-is OR they can be extended like any other component OR they can be created right from scratch.

To start with, formhandlers mostly are of "request" scope as we dont want our form-data to be manipulated multiple times. If our formhandler's scope is session or global, our submitted form data can be modified within a session or globally by any user worldwide.

A form handler class must include one or more handler methods. A handler method is typically invoked when the user clicks the submit button, and handles the processing of the form. Depending on the purpose of the form handler, it can have several different handler methods that each perform a different operation.

XML Files Combination

    An XML file might appear at several points in the CONFIGPATH. The ATG platform, at runtime, automatically combines all the XML files in the CONFIGPATH with the same name into a single composite file, which is then used by the appropriate component.
    When two files are matched up, the way that they are combined is defined by an extra attribute that is specified in file 2 called xml-combine. This attribute is used only to specify how the files are combined, and is removed before the resulting file is generated. The xml-combine attribute can have the following values:

• xml-combine="replace"
• xml-combine="remove"
• xml-combine="append"
• xml-combine="append-without-matching"
• xml-combine="prepend"
• xml-combine="prepend-without-matching"

Product Catalog Database Diagram

    Devido a baixa cobertura da documentação Oracle ATG e a grande quantidades de tabelas no banco de dados, há uma certa dificuldade em visualizar graficamente as relações entre as entidades.
    Para melhor entendimento do relacionamento entre as tabelas, segue abaixo três imagens do diagrama de entidade relacional do Catalogo de Produtos.

DSP Tag Libraries

       The DSP tag library lets you work with Nucleus components and other dynamic elements in your JSPs. DSP library tags support both runtime expressions, such as references to scripting variables, and the JSTL Expression Language (EL) elements, which also evaluated at runtime.
       DSP tag names and attributes that have equivalent names in HTML, JSP, or WML typically replicate the functionality of the corresponding tag while providing extra functionality. One exception applies: the  iclass  attribute is used in place of the class attribute to avoid using a standard method name in Java code.

See tags table below...

Quick Tutorial to How to Create a Custom Droplet

In this quick tutorial we'll learn how to create a custom droplet and invoke it in jsp

1- First create a new class that extends atg.servlet.DynamoServlet. You may place it inside a specific package for droplets, like: com.atgendecabr.droplet, so you keep things more organized.

ATG Web Commerce History

O ATG, or Art Technology Group, began as a independent enterprise specialized in e-commerce applications. It was founded  by Jeet Singh and Joseph Chung in 1991.

Nucleus: Conhecendo a ferramenta. / Nucleus: Inside the tool.

Nucleus: Conhecendo a ferramenta.

Neste breve artigo será apresentada uma explicação sobre o funcionamento e o ciclo de vida do nucleus, outros artigos mais específicos serão criados de modo a abordar determinadas funcionalidades do modelo.

A ferramenta nucleus é uma parte muito importante do sistema ATG (Art technology Group ou Oracle commerce), com ela é possível criar componentes, inicializa-los e também passar parâmetros. O nucleus controla o ciclo de vida de todos os componentes da aplicação por meio de um arquivo de configuração que vamos entender como funciona abaixo.

Nosso Objetivo

Já notou como é difícil encontrar artigos e tutoriais sobre nossos amados ATG e Endeca?
Pois foi pensando exatamente nisso que decidimos criar este blog, através do qual transmitiremos todo o conhecimento adquirido, além de vários tutoriais e boas práticas.

Contamos com a ajuda e sugestões de vocês nos nossos comentários. :)

Endeca 11.1.0 Installation and Configuration

Before starting, it is a good practice to set a hostname to the machine and configuring it in the /etc/hosts machine. In this example the hostname is defined as ‘endeca’.

You need to download the installers at http://edelivery.oracle.com. In the box ‘Select a Product Pack’ chose Oracle Endeca and in platform choose Linux x86 , to systems of 32 bits or Linux x86-64 to systems of 64 bits. Click in ‘Go’. Select ‘Oracle Commerce (11.1.0), Linux’ and make the download of the following installers:

Oracle Commerce MDEX Engine 6.5.1 for Linux
Oracle Commerce Content Acquisition System 11.1 for Linux
Oracle Commerce Experience Manager Tools and Frameworks 11.1 for Linux
Oracle Commerce Guided Search Platform Services 11.1 for Linux
