Oracle on Wednesday announced the public release of Java Platform Enterprise Edition 7 (Java EE 7) and the Java EE 7 SDK.

A recent study by Java developer Raghu Kodali has shown that porting Sun’s Java EE tutorial application RosterApp from EJB 2.1 to EJB 3.0 resulted in more than a 50-percent reduction in code.

Sun Microsystems has thoroughly invested itself in addressing these challenges. The result, released this month, is Sun’s Java 2 Enterprise Edition (J2EE) software developer’s kit (SDK).
