As a Professor at Purdue University, specializing in advanced software development using Java-based technologies, I am always on the lookout for motivational background materials that provide comprehensive subject matter examination while at the same time does not put students to sleep. "Head First EJB" overwhelmingly fits the bill ! Books like this are extremely rare.

I have added this book as one of the required texts for future offerings of my advanced undergraduate "Enterprise Application Development" course

Kudos to the authors; Keep up the great work !
