com.ecyrd.jspwiki.workflow.Workflow

te workflow; owner is current user 1 Workflow workflow = new Workflow("workflow.myworkflow", context.getCurrentUser()); // Create custom initialization task 2 Step initTask = new InitTask(this); // Create finish task 3 Step finishTask = new FinishTask(this); // Create an intermediate decision step 4 Principal actor = new GroupPrincipal("Admin"); 5 Step decision = new SimpleDecision(this, "decision.AdminDecision", actor); // Hook the steps together 6 initTask.addSuccessor(Outcome.STEP_COMPLETE, decision); 7 decision.addSuccessor(Outcome.DECISION_APPROVE, finishTask); // Set workflow's first step 8 workflow.setFirstStep(initTask);

Some comments on the source code:

Line 1 instantiates the workflow with a sample message key and designated owner Principal, in this case the current wiki user
Lines 2 and 3 instantiate the custom Task subclasses, which contain the business logic
Line 4 creates the relevant GroupPrincipal for the Admin group, who will be the actor in the Decision step
Line 5 creates the Decision step, passing the Workflow, sample message key, and actor in the constructor
Line 6 specifies that if the InitTask's Outcome signifies "normal completion" (STEP_COMPLETE), the SimpleDecision step should be invoked next
Line 7 specifies that if the actor (anyone possessing the Admin GroupPrincipal) selects DECISION_APPROVE, the FinishTask step should be invoked
Line 8 adds the InitTask (and all of its successor Steps, nicely wired together) to the workflow
