Http://java.sun.com/developer/technicalArticles/J2se/desktop/mustang/beta2.html describes what you should know about Java 6 is as follows.
Web Services. Prior support to write XML Web Service client programs. You can use simple Annotaion to release your API to the web services. MUSTANG adds new resolution and XML in the Java Object-maping apis, before only the Java EE platform is implemented or in Java Web Services Pack. Now you can mix JavaScript in the Java source code, which is useful to develop prototypes, you can also insert your own script engine. Database. MUSTANG will bind Java DB (Apache Derby). JDBC 4.0 adds a number of features, such as supporting XML as SQL data types, better integration binary large objects (blobs) and Character Large Objects (Clobs). More Desktop APIP. GUI developers can have more techniques to use SwingWorker Utility to help multi-threads in the GUI app. , JTable classification and filtration, and add SPLASH flash screen. MONITORING AND Management. MUSTANG Add more diagnostic information, binding is not a very well-known Memory-HEAP analysis tool jhat to see the kernel export. Compiler Access. Compiler API provides programming Access Javac, you can implement compilation within the process, dynamically generate Java code. Pluggable Annotation. Java Tool and Framework providers can define their ANNOTATIONS, and kernel supports custom ANNOTATION plugins and executes processor Desktop deployment. Swing has better Look-And-Feel, LCD text presence, overall GUI performance improvement . Java applications can be integrated with local platforms, such as access to the platform's system tray and start menu. MUSTANG unifies the Java plugin technology and the Java Web Start Engine. Security. XML-Digital Signature (XML-DSIG) APIs are used to create and manipulate digital signatures); new methods to access secure services for local platforms, such as local Microsoft Windows for Secure Authentication and CommunicationNative Public Key Infrastructure (PKI) and Cryptographic Services, Java Generic Security Services (Java GSS) and Kerberos Services for Authentication, and access to LDAP Servers to authenticate users. The -ILITIES: quality, compatibility, stability. 80,000 Test Cases and millions of row test code (only one of the test activities). Mustang's snapshot release has been downloaded for 15 months, and the bug in each step is fixed, and the performance is better than J2SE 5.
