Reverse Engineering Sequence Diagrams for Enterprise JavaBeans with Business Method Interceptors

Enterprise JavaBeans (EJB) is a component technology commonly used for enterprise application development. Recent EJB 3.0 specification involves interceptors, a mechanism providing means to dynamically introduce additional behavior into the execution of a bean. As multiple interceptors can be applied to the same bean, and the order of interceptor invocation can be affected by a variety of specification rules, complexity of interceptors invocation can easily become a burden for the developers or maintainers. In order to help the developers we propose an algorithm for reverse engineering UML sequence diagrams from EJB 3.0 programs.
