OSWorkflow的第五支程式
第五支程式要用OSWorkflow提供的API做查詢，查詢出已完成工作流的工作流編號。
程式

public class Query extends AbstractWorkflow {
public List getCompleted() {
FieldExpression fe = new FieldExpression(FieldExpression.STATE,
FieldExpression.ENTRY,
FieldExpression.EQUALS,
new Integer(WorkflowEntry.COMPLETED));
List list = null;
try {
list = getPersistence().query(new WorkflowExpressionQuery(fe));
} catch (StoreException e) {
e.printStackTrace();
}
return list;
