Abstract

We present here a tool to generate given the CCS automatically for the distributed multithreaded system coded in JAVA. Actually in the current scenario distributed systems are get emphasized and hard fact is to verify these systems. CCS (Concurrent communication system) is one of the ways to write formal specifications for concurrent systems but it is quite difficult to write CCS for given distributed system more over dynamic environment, where threads and processes created at runtime. is quit impossible analyze, audit and codify simultaneous. So as per requirement for verification of distributed system, we developed a tool named as Refjav that takes input a java coded file of system that is to be verified and produced output as its equivalent CCS under the set of reasonable restrictions. In present we worked with synchronization, dynamic thread creation and their communication using RMI in distributed, multithreaded Java program. Paper covers the various constructs of Refjav tool and its methodology. Our work is useful for getting CCS of a given Java distributed multithreaded program, which can be verified easily by model checkers to verify properties, expressed in model μ-calculus. As a result we should be in position to comment on the properties of system such as Deadlock, fairness etc, without actually going through the actual details and constructs of CCS.
