This paper proposes a standard open source software development guidance and an evaluation index for the productivity related to Seam 2.0 and Spring 2.5 framework. However, there is no comparison research about the performance of Seam 2.0 and Spring 2.5 framework with same identical platform. Quantitative analysis is supported as a part of LoC 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 Seam 2.0 and Spring 2.5 framework on a platform. Base on the result, the specific guidance of the developing software is obtained.
