Of course there’s already the Java EE 5 Tutorial, but now there’s also “EJB 3, Des concepts à l’écriture du code. Guide du développeur”. Yes, it’s in French and it’s very good too. It was written by a group of talented and passionate students from the SUPINFO Sun Lab in Paris who asked me to proof-read it (and write a short foreword).
The book deals with all flavors of EJB’s, JPA, has a section on my favorite Java EE 5 feature: Application Client Container (ACC) which becomes so much more relevant with client-level resource injection (WebServices refs, datasources, security context, …) and GlassFish’s Java Web Start feature as the extra mile to ease deployment. The book also covers GlassFish, NetBeans, JBoss, and Eclipse WTP in a dedicated chapter, has a full sample application using Seam running on GlassFish).
Maybe this is the first book mentioning GlassFish?
