Sun 最近提交了JSR 224－Java EE 5的 最后草稿。Java EE 5 最關(guān)鍵的地方，就是開發(fā)將更加簡易，將更關(guān)注小到中型系統(tǒng)的開發(fā)。JSR-244規(guī)定了Java EE 5總體框架下需要具備的技術(shù)特性，其中的各項技術(shù)又分別由其他JSR所規(guī)定。從提交公開審查的規(guī)范草案Java EE 5的來看，Java EE 5的關(guān)注重點是簡化應(yīng)用開發(fā)，尤其是大量采用元數(shù)據(jù)標(biāo)注（annotation）和POJO（普通Java對象）驅(qū)動的開發(fā)方式，對平臺進(jìn)行了重新定義。官方提到：The major theme for the next version of Java EE is ease of development. The clear message we've heard from Java EE vendors and users is that the Java EE platform must evolve quickly to support a wider range of developers, including less sophisticated developers. JSR-175 (A Metadata Facility for the JavaTM Programming Language) is the enabling facility for a new declarative style of programming that significantly simplifies many programming tasks. Java EE must move quickly to take advantage of this capability and deliver significant improvements to ease of development for Java EE developers. In particular, this capability will be used to simplify the development of web service applications.對Java EE 5你有何期待？
