Introduction to CQ5The way developers like it


Current Version – 5.6Now called as the Adobe Experience Manager

Pre-requisites – Java v1.7, 4 GB RAM (min), CRXDE And that’s apart from a valid jar and license

Installation is double clicking a JAR(No I am not kidding !)

Set up as AuthorThat’s where all the content is generated. Called the run-mode

Getting Started


Key Technologies

OSGi• The Universal Middleware. Container for Bundles. Uses Apache Felix

JCR• Java content Repository. Everything is content. Implementation used –

CRX

Apache Sling

• The REST framework responsible for delivering content form JCR

CQ WCM API

• Pages, Templates, Components, Workflows and everything else CQ is made up of

EXTJs

• Sencha JavaScript framework. Used for UI


Key Terms

Template• The Blue print to make a page

Pages• This is what the Author creates

Components• Part of templates and this is where

you will spend a lot of your time. JSP, JS, CSS, i18n, ExtJs

Dialog• User Interface to collect

information from an Author. Custom created. ExtJs

Widgets• Each line item in a dialog. Sits

inside a widget collection. ExtJs

Workflow• The more I tell you the more I scare

you. Model a workflow, Run it, See the inbox, Step ahead.. Phew


OSGi

Bundles

• Your Java Code. Basically a Jar with some meta information

Services

• This is what you will use and write for other bundles

Blah Blah

• Modules, Runtime and Security. Class Loader example


JCR Terms

Node

• It’s the structure

Properties

• And the content. Key/Value(s) format• API


JCR Structure ID FN LN1 A A2 B b

Employee

URL – From JCR

Protocol – HTTP

Sling HTTP Request/ Response

POST handler

Other Essentials

Publish and Author instances

The 4502 secret

• Default port

Sidekick & Content Finder

• On the Authoring Page. CF is used to add content (from DAM) and Sidekick to add components and more


Deployment

• CQ is a powerful rendering engine built on powerful standards. CQ runs with a webserver for content delivery. Makes Sense as well

Dispatcher

• Replication Agent. Reverse Replication AgentPublish – Author

relationship

• Lives in clusters. Single instance is a cluster of 1
