What This Book Covers

Chapter 1 is for people new to the Alfresco platform. It walks you through the capabilities of Alfresco and gives some examples of the types of solutions that can be built on the platform. You'll also learn what tools and skills are required to implement Alfresco-based solutions.

Chapter 2 is about getting your development environment set up. Like preparing for a home improvement project, this is the trip to the hardware store to get the tools and supplies you'll need to get the job done. Throughout the book, you will be building and deploying changes. So just as in any software development project, it pays to get that process working up front. You'll also learn about the debugging tools that are available to you. The chapter includes a short and simple customization example to test out your setup.

Chapter 3 starts where all Alfresco projects should begin: defining the content model. You'll learn how to define the content model as well as how to expose the model to the Alfresco web client. Once you've got it in place, you'll write some Java code that utilizes the Web Services API to test out the model. This will also be your first taste of the JavaScript API. The exercises set up the initial content model for SomeCo.

Chapter 4 begins to show you the power of the repository by exposing you to some of the mechanisms or hooks that can be used to perform "hands off" operations on content. You'll learn about actions, behaviors, transformers, and metadata extractors. The exercises include implementing a rule action for SomeCo's Human Resources department to help manage HR policies, writing a custom behavior to calculate user ratings, and writing a custom metadata extractor to make Microsoft Project files indexable by the Lucene search engine.

Chapter 5 takes you through web client customizations. First, it establishes whether or not you should be customizing the web client at all. Once that's out of the way, you learn how to add new menu items, how to create your own custom component renderers, and how to define new dialogs and wizards. Examples in this chapter include writing a new "Execute Script" UI Action to make it easier to run server-side JavaScript, creating a "Stoplight" component to graphically show project status, and creating a multi-step wizard SomeCo's HR department can use to set up job interviews.

Chapter 6 focuses on the web script framework. Web scripts are an important part of the platform because they allow you to expose the repository through a RESTful API. They are also core to the Surf framework that is in the 3.0 release. The exercises in this chapter are about creating a set of URLs that can be called from the frontend web site to retrieve and persist user ratings of objects in the repository.

Chapter 7 is about advanced workflows. You'll learn how the embedded JBoss jBPM workflow engine works and how to define your own workflows, including how to implement your own business logic. The chapter includes a comparison between the capabilities of Alfresco's simple workflow and advanced workflow so that you can decide which one is appropriate for your needs. By the end of the chapter, you will have built a workflow that SomeCo will use to review and approve Whitepapers for external publication. The process includes an asynchronous step, which leverages the web script knowledge you gained in the previous chapter.

Chapter 8 takes you through the key developer-related aspects of Alfresco's Web Content Management functionality. The chapter is not an exhaustive WCM how-to. Rather, the chapter starts with a simple web form and then quickly moves to using the API to work with WCM assets. You'll also leverage advanced workflow and web script techniques you learned in previous chapters to work with WCM sites and assets. You'll create a "no approval" workflow that SomeCo will use for Job Postings and web scripts developers can use to deploy web sites to test servers and to commit changes to staging.

Chapter 9 covers a variety of security-related topics. You'll learn how to define your own custom roles, and how to create users and groups with the API. Although not strictly developer-centric, you'll also learn how to configure Alfresco to authenticate and synchronize with an LDAP directory and how to implement Single Sign-On (SSO) between Alfresco and other web resources.

A set of Appendices is included at the end of the book. There you'll find reference information such as the JavaScript API, a set of diagrams showing the out-of-the-box content model, and a list of the out-of-the-box public spring beans.

Appendix C is available for download from the book's page on Packtpub.com. You can visit http://www.packtpub.com/files/3117_AppendixC.pdf to directly download it. It includes a section on packaging and deploying AMPs, and an overview of the new Surf framework.
