JSR-244規定了Java EE 5總體框架下需要具備的技術特性，其中的各項技術又分別由其他JSR所規定。從提交公開審查的規范草案Java EE 5的來看，Java EE 5的關注重點是簡化應用開發，尤其是大量采用元數據標注（annotation）和POJO（普通Java對象）驅動的開發方式，對平臺進行了重新定義。
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.
