I've just completed a rewrite of Learning Tree's course 936, Building Modern Java Enterprise Apps: JPA, EJB3, JSF, & AJAX. Details at https://learningtree.com/courses/936 There's a lot that goes into creating one of these courses: instructional design aspects, writing slide, preparing exercises (both code and instructions), then putting it all together, test, tweak, test again, repeat until done... Oh, and the marketing too... At any rate, it's now been turned in, and we'll see how it fares.
