attribute.setValue("123");
attributes[1] = attribute;
vsoWebControl.answerWorkflowInput(token.getId(), attributes, username,
password);
}
In the preceding example, if the workflow is in the waiting state, the application creates two
WorkFlowTokenAttribute objects. The objects call the various WorkFlowTokenAttribute operations to
obtain the attribute values. The process then adds these WorkFlowTokenAttribute objects into a
WorkflowTokenAttribute array.
4 Cancel a workflow by calling the cancelWorkflow operation.
You can cancel a workflow at any time using the cancelWorkflow operation.
vsoWebControl.cancelWorkflow(workflowTokenId, username, password);
5 Check that the workflow canceled successfully.
Because the cancelWorkflow operation does not return anything, you must obtain the WorkflowToken
status to make sure the workflow canceled successfully, as the following code example shows.
String[] status = vsoWebControl.getWorkflowTokenStatus(tokenIds, username, password);
if ("canceled".equals(status) == true) {
System.out.println("Workflow canceled");
}
The Web service client interacts with workflows by finding their status, supplying input parameters from
user interactions, and by canceling the workflows.
What to do next
Implement operations in the Web services client to extract the workflow results.
Obtain Workflow Results
After the workflow completes its run, you can retrieve the results by calling the getWorkflowTokenResult( )
operation.
Prerequisites
You must have implemented how workflows start in the Orchestrator server in the Web services client.
Procedure
1 Obtain the results of a running workflow by calling the getWorkflowTokenResult( ) operation.
The getWorkflowTokenResult( ) operation stores the results as an array of attributes.
WorkflowTokenAttribute[] retAttributes =
vsoWebControl.getWorkflowTokenResult(token.getId(),
username, password);
The preceding example code obtains the result of a workflow token with a specific identifier.
2 (Optional) Print the workflow results.
WorkflowTokenAttribute resultCode = retAttributes[0];
WorkflowTokenAttribute resultMessage = retAttributes[1];
System.out.println("Workflow output code ... (" + resultCode.getValue() + ")");
System.out.println("Workflow output message... (" + resultMessage.getValue() + ")");
