In turn, it is possible to invoke any Javabean,java object that has already been registered in these scripting language.

Commons-chain.jar: is a Java class library that implements the design pattern of the chain of responsibility. As a program developer, we often need to apply an object-oriented approach to an actually procedural system. Business analysts and managers describe systems that typically do not use class hierarchies and sequence diagrams, but rather use flowcharts and workflow diagrams. However, using an object-oriented approach to solve these problems can give you more flexibility. The object-oriented design pattern provides useful structures and behaviors to describe the processing of this order, such as the template method [GoF] and the chain of responsibility (Chain of Responsibility) [GoF]. Jakarta Commons sub-project chain combines the above two patterns into a reusable Java framework for describing the sequence of processes. This framework, developed in the Jakarta Commons project community, has been widely accepted and used in many interesting applications, notably the struts and shale application framework as the underlying mechanism for handling HTTP request processing. You can use Commonschain when you need to define and execute a contiguous set of steps.

Over the past few years, these elements have been well integrated with the experience accumulated during the JBPM build process, and jBPM5 is on this basis. But JBPM's vision has not changed, but has been expanded. Drools flow will no longer evolve independently, and the latest version of Drools is already using JBPM5 to process its process requirements.
