With version 5 of the Java Platform, Enterprise Edition (Java EE, formerly referred to as J2EE), development of Java enterprise applications has never been easier or faster. J2EE 1.4, the predecessor to the Java EE 5 platform, has many powerful features. The aim of the Java EE 5 platform design has been to streamline these features and add convenience, improve performance, reduce development time, and help developers get products to market that much sooner.
