Snaker is a Java-based open source workflow engine for common business processes in enterprise applications. Designed based on the concept of light weight, simplicity and dexterity, aiming at simple integration and multi-environment support
Lightweight: snaker-core.jar is 208K in size, with about 7000 lines of code, powerful extension support, and does not depend on specific ORM frameworks
Simple : simple table design, simple process components [start/end/task/custom/subprocess/decision/fork/join]
Dexterity : Expose a large number of extensible interfaces, support component model customization of process designers and process engines
dexterity:
