The purpose of this study is to provide a quantitative evaluation index of object-oriented software development productivity for EJB 3.x. The lightweight container architecture is a newly-developed architecture in order to solve demerits that N-Tiers enterprise architecture has and to support merits therein. However, there have been insufficient studies on a performance evaluation of EJB 3.x on an identical platform. Since a quantitative analysis has been performed only with respect to a partial LoC(Line of Code) analysis, there have been insufficient objective evaluation indices and guidelines for a new specification released. Accordingly, there has been limited evaluation of software development productivity and on new innovations in a project. This study then intends to provide evaluation guidelines for an objective software development productivity comparison by development platform environment.

This paper proposes an object-oriented software development guidance and an evaluation index for the productivity related to Spring Framework 2.0 and 2.5. Spring Framework is a known successful open source standard model for lightweight container architecture. However, there is no comparison research about the performance of Spring Framework 2.0 and 2.5 with same identical platform. Quantitative analysis is supported as a part of LOC(Line Of Code) analysis. There is a limit to develop the updated software with no the specific evaluating index for the productivity of the software. This work proposes an specific index for evaluating the productivity of new version Spring Framework on a platform. Base on the result, the specific guidance of the developing software is obtained.
