Building workflows

So we've been over the basics of activities. Remember they are just Java bean so you can implement them however you wish.

However often folks think of workflows as a number of discrete steps; using a kind of state machine to move from step to step. One real simple approach to
writing workflows in this model is to use a method to map to a workflow step.

The following example is a fairly large one, but it shows a variety of different concepts

• suspending workflows (such as when they wait for external events such as user input or an asynchronous message to arrive)
• looping & using predicates
• forking and joining child activities
• declaratively moving from one step to another
