Sun Microsystems latest Java version is JSE6 (Java Platform, Standard Edition 6), code named "Project Mustang."
Expanded scripting language and Web services support:
Java SE 6 software is clearly emerging as the next-generation platform for Web 2.0 applications and services.
The new JSE6 also provides expanded tools for diagnosing, managing and monitoring applications. This includes better support for Sun's DTrace, open-source dynamic tracing framework for Solaris, and tool interface updates for JVMs (Java virtual machine) and the JDBA (Java Platform Debugger Architecture).
Sun has also tried to improve JSE's integration with the desktop in this edition. The company claims that with tighter integration with native desktop facilities, Java applications will be better able to emulate native platform look and feel, text printing, drag-and-drop capabilities and table display and manipulation.
