Grails convience capabilities
Typical configuration
Easy business archive deployment
Generate controllers/view/example app

Hello World <process id= ”helloWorldProcess" name= “My first process" > <startEvent id= "theStart" /> <sequenceFlow id= "flow1" sourceRef= "theStart" targetRef= "theTask" /> <userTask id= "theTask" name= "my task" /> <sequenceFlow id= "flow2" sourceRef= "theTask" targetRef= "theEnd" /> <endEvent id= "theEnd" /> </process> Activiti Modeler, MS Visio, Aris, (Oracle) ProcessEngine engine= new ProcessEngineBuilder() .configureFromResource( “activiti.cfg.xml” ) .buildProcessEngine(); engine.getRuntimeService().startProcessInstanceByKey( “helloWorldProcess” ); Task task = engine.getTaskService().createTaskQuery().singleResult(); Engine.getTaskService().complete(task.getId());

Real-life demo
Use case: banks shouldn’t lend money to just anybody
Thorough analysis is needed
All steps needs to be recorded in official documents
Decisions are done based on Excel decision tables

The mortgage process

The mortgage process = CMIS call

The power of Java Out-of-the-box Custom Java

The power of Java public class CreateLoanApplicationDocument implements JavaDelegation { public void execute(DelegateExecution execution) { Session session = CmisUtil.createCmisSession("admin", "admin", Constants.ALFRESCO_URL); Folder folder = CmisUtil.getFolder(session, Constants.LOAN_APPLICATION_STORAGE_FOLDER); Document document = createWordDocument(session, folder, execution); storeDocumentReferencesAsProcessVariables(execution, folder, document); session.save(); }

The cool stuff
That didn’t make it in the demo
But is just too cool not to show you
Unit test support
Query API
Spring integration
Method expressions
JPA integration

Unit testing your processes
With Activiti, business processes
Live and breath along your regular app code
Should be tested just the same !
Typical BPM vendor & testing
Activiti supports Junit 3 & 4 and offers lots of convience while testing

Query API
No need to learn the intern data model
Powerful and uniform query API
Deployments and process definitions
Process instances and executions
History
Variables
Tasks, jobs, users, groups, historic activities/process instances/variables, …
repositoryService.createProcessDefinitionQuery.keyLike(“%mortgage%”).latest();
runtimeService.createProcessInstanceQuery
.processDefinitionKey(“mortgage-process)”.orderByProcessInstanceId().desc();
historyService.createHistoricActivityQuery().processDefinitionId(procDefId)
.activityType(“userTask”).orderByDuration().asc();
runtimeService.createProcessInstanceQuery()
.variableValueGreaterThan(“amount”, 50000);

Spring integration
ProcessEngine as a Spring bean
Delegate to Spring beans
<bean id=“printer” …

Method expressions & JPA Process variables Spring bean Decision based on JPA entity property
