In this paper, we propose an approach object oriented software development guidance and evaluation index for the productivity related to EJB(Enterprise JavaBeans) with J2EE development platform. In the digital convergence life, EJB become known success standard model of size distributed object. However, the EJB specification of 2.0 and 3.0 is lack of software development productivity comparison research in an identical platform until now. In addition, quantitative analysis support and try a part of LOC(Line of Code) analysis. Therefore, it limited a new attempt of software development productivity evaluation. Our approach is objective validity of the new EJB Specification after presenting of analysis of quantitative evaluation index in the same platform related with EJB 2.0 and 3.0. Base on the result, it suggests objective software development productivity research guidance.
