In my view, the development of UNSAE 2.0 is at least 10 months late to start up after the finish of UNSAE 1.0, so we should hurry up to carry back what we lost before.

    And beyond that, we should also make a plan to develop UNSAE 2.5(or 5.0) in a little future. since UNSAE 2.0 framework is figured on Java SE 1.4 level and Java EE 1.3 level, to be "modern", UNSAE 2.5 will be constructed for running on Java SE 5.0 and Jave EE 1.4 platforms. The obvious things need to do about UNSAE 2.5 are:

• Re-code it with Java Programming Language 3.0
• Add JMX support
• ... ...

• A little good work
  
• Just a tiny experiment
• Maybe a ugly framework
• Definitely need much more improvements
  

• All good staffs
• Missing each other for long time
• Best regards for everybody here!

• a better include manner
• combining the url-def and screen-def in one file is more readable
• form-bean added newly for auto parameter populating
• web-dir is for supporting mutiple modules
  

• Adjust and optimize the net service architecture.
• Make it more compact, agile, robust, efficient, easy-to-use and hot-load enabled.
• O-R mapping and SQL sentence insulation.
• More web-tier components.

• Distributed transcation support.
  
• Clustered cache.
• Simplified JDO support.
  
• Simplified DMA support.

• Simplified Workflow support.
• Eclipse plugins for developers.
• ... ...

UNSAE project is aimed to construct a java-based, easy-to-use, compact and efficient web application framework for developers and customers.
