I'm attending a company sponsored training event for JSF and JPA that crams 10 days of training into 5 days. I plan on getting all that I can out of the class, but there is no final exam.
Is JSF and JPA worth learning?
java;jpa
JPA - Yes absolutely, it's the standard underpining most Java ORM libraries out there (e.g. Hibernate).JSF? - Not so much, it's not seen as a dominant std (that said, no web framework is the dominant std) and is expected to keep slipping in terms of mind-share and deployment (unless some radical changes are made).
