The technical differences between the Java world and Microsoft world are minor compared to the conceptual differences between them. While the Microsoft concept is concerned with “we’ve got excellent technology for you guys; just adjust your business to work with our products and we will fulfil your dreams”, the Java world concept works the other way around. The Java guys follow the line of “Understand your business needs and constraints and then just pick the right technology from our tool set”. You can notice this difference of concepts in each and every aspect of these different worlds.
