Abstract: A method for MDA implementation, especially on the EJB platform, is proposed in the paper based on pattern and action semantics. First, the applications of patterns during different phases of MDA implementation are illustrated. Then the implementation method is described with action semantic meta language. Last, the method is proved feasible with a bank model example. The method is considered to be of evident significance to the application of MDA specification.
