  For some years there has been much activity in developing CSP-like extensions to a number of common programming languages. In particular, a number of groups have looked at extensions to Java. Recent developments in the Java platform have resulted in groups proposing more expressive problem solving environments. Groovy is one of these developments. Four constructs are proposed that support the writing of parallel systems using the JCSP package. The use of these constructs is then demonstrated in a number of examples, both concurrent and parallel. A mechanism for writing XML descriptions of concurrent systems is described and it is shown how this is integrated into the Groovy environment. Finally conclusions are drawn relating to the use of the constructs, particularly in a teaching and learning environment.
