After graduating from Supelec (French "Grande Ecole"), Emmanuel has spent a few years in the retail industry as developer and architect where he started to be involved in the ORM space. He joined the Hibernate team in 2003 and is now a platform architect at JBoss, by Red Hat. Emmanuel is the lead developer of Hibernate Annotations and Hibernate EntityManager, two key projects on top of Hibernate Core implementing the Java Persistence(tm) specification. He also has founded and leads Hibernate Search and Hibernate Validator.

Emmanuel is a member of the JPA 2.0 expert group and the spec lead of JSR 303: Bean Validation. He is a regular speaker at various conferences and JUGs, including JavaOne, JBoss World and Devoxx and the co-author of Hibernate Search in Action published by Manning.

Hibernate Validator / Bean Validation Best practices

Bean Validation, and its reference implementation Hibernate Validator, is one of the new APIs available to Java SE and Java EE developers. It standardizes constraint declarations and validation in a Java application.

In this session, attendees will dive into concrete usages and best practices, including the more advance concepts. They will explore most of the specifications, as well as:

Using constraints, including groups
Writing constraints (composition, error report customization, etc.)
Customizing Bean Validation
Exploiting its metadata
Constraint declarations and definitions
Runtime customization
Metadata usages

After a brief conceptual introduction, Emmanuel will conduct a live coding demo for using and writing constraints. He will show an example of groups usage, discussing how they are created and used. Emmanuel will also write a couple of constraints using some advance composition patterns including the multi-property validation.

This session is intended for both newcomers and intermediate users of Hibernate Validator and Java EE 6 who want to increase their knowledge of the API.

Hibernate OGM: JPA on Infinispan: when PaaS persistence meets Java EE

PaaS (Platform as a Service) is all the buzz these days. But how and where do you store your data is the real challenge. In a data grid to benefit from its scalability? Via a new proprietary API?
JBoss users of our enterprise middleware systems are accustomed to easy persistence via Hibernate and JPA (Java Persistence API). What if Hibernate could store your data in a grid?

Hibernate Object/Grid Mapper (OGM) aims at offering a JPA front end (object manipulation and JP-QL query) to applications while storing and querying the data from a key/value grid like Infinispan. In other words, offering a familiar and well known API but benefiting from the new scalability possibilities of distributed data grids like Infinispan. That includes trying to support existing applications using JPA.

In this presentation, we will see how JBoss is leveraging its existing technology to build an OGM (Object/Grid Mapper). Hibernate Core (JPA), Hibernate Search (object search engine), Teiid (query federation engine) and of course Infinispan (distributed data grid) are the foundation to this adventure. We will cover in details how the various bricks fit together, what the secret sauce is and how to use the solution in your applications.
