● J2EE popularized the idea of server-side architectures
○ J2EE Blueprints (aka “Java Pet Store”)
● J2EE Blueprints had profound impact, but not without its problems
○ Many of the paradigms are alive and well even today
○ Encumbered by the immaturity of the technology/industry
● Domain-Driven Design (DDD) emphasizes a return to the roots of object-oriented

● Jakarta EE’s lightweight programming model fits DDD philosophy well
○ The Cargo Tracker project completes the circle
