Workflow Overview
A workflow is a JavaBean component that performs a specific set of tasks connected together in a causal way that enables ordering of the set of tasks based on task completion. The tasks can be work items or other workflows.
This chapter describes the basics of the Workflow application, including how the workflow engine executes a workflow, the workflow language that specifies the rules for connecting components to produce workflows, the classes used to build workflows, the types of work items, and persistent storage and how it affects the execution of workflows.
