Seam 2.x Web Development

Overview of this book

The Seam framework from JBoss allows developers to use JSF, Facelets, EJB, and JPA to write conversational web applications. But you will first have to learn how these standard technologies are integrated using Seam and how they can be built upon using additional Seam components. If you need to build a Java web application fast, but don't have time to learn all these complex features, then this book is for you. The book provides a practical approach to developing Seam applications highlighting good development practices. It provides a complete walk through to develop Web applications using Seam, Facelets, and RichFaces and explains how to deploy them to the JBoss Application Server. You can start using key aspects of the Seam framework immediately because this book builds on them chapter by chapter, finally ending with details of enterprise functionality such as PDF report generation and event frameworks. First, the book introduces you to the fundamentals of Seam applications, describing topics such as Injection, Outjection and Bijection. You will understand the Facelets framework, AJAX, database persistence, and advanced Seam concepts through the many examples in the book. The book takes a practical approach throughout to describing the technologies and tools involved. You will add functionality to Seam applications after you learn how to use the Seam Generator RAD tools and how to customize and fully test application functionality. Hints and tips are provided along the way of how to use Seam and the JBoss Application Server.

The Seam identity manager API


The Seam identity manager API provides a standard interface for identifying management functionality, for example, creating users or assigning roles to users, irrespective of the security-backing store. The security-backing store may be implemented as either database tables via JPA or via LDAP (Lightweight Directory Access Protocol).

The Seam identity manager is new to Seam 2.1, and provides fine-grained security access permission on top of security roles. We will discuss the identity manager API briefly in this section, so that we have a good understanding of what it can achieve. In particular, we'll pay attention to how to create users and assign roles to them by using a JPA-based security-backing store.

To use the Seam identity manager with a JPA backing store, we need to specify which JPA classes represent our user and role entities. This is achieved by using the <security:jpa-identity-store> element within an application's components.xml file. To...
