Estimation of effort for component based software has been in focus of researchers. Various models have been suggested by number of scientists. The most popular model is Cocots model in which major cost ingredients are integration cost i.e. the cost of glue codes, assessment costs and cost of tailoring the components. Many researchers have proposed formulas for evaluating assessment and tailoring costs theoretically. Major problem found in the existing work is calculation of integration cost. This cost cannot be evaluated through some formula or theoretical calculations as the amount of code required as glue code is not predictable using these methods. This paper proposes the evaluation of the glue code cost using UML diagrams. A Java Parser Tool has been developed to evaluate the glue code by parsing through the XMI file. For the support of the proposed system an existing UCRS system used to evaluate cost through implementation of it.
