This session will demonstrate the Activiti tools in the context of the full software development cycle. Starting from business people over developers to system administrators. Activiti facilitates the collaboration between those roles in a pragmatic and new way. For the developer part, we'll briefly dive a bit deeper. With code samples we'll give you a look under the hood.

1. A new kind of BPM with Activiti 2 Tom Baeyens & Joram Barrez Alfresco twitter: @tombaeyens @jbarrez

3. Passionate about Java and BPM

5. Core developer Activiti

7. Activity = Execution step in your application

8. Configure out of the box activity types

9. User task

10. Email

11. Script

12. Web service

13. JMS

14. EJB

15. Delegate to Java& scripting where necessary

17. Persist state of an execution flowExecution EmplJohn Doe Date 5/10/2010 Doc vacation.xls State Approved

19. Create new execution

20. Pass initial data in (optional)

21. Take transition to “Fetch data from DB”

22. Execute “Fetch data from DB”

23. Take transition to “Wait 1”

24. Stop interpreting process

25. Persist state

26. ReturnExecution

27. Transactional Control Flow 7 INSERT INTO ACT_RU_EXECUTION (…, ACTIVITY_ID_, …) values (…, ‘Wait’, …) Execution

29. Load existing execution

30. Pass data in (optional)

31. Take transition to “Wait 2”

32. Stop interpreting process

33. Update runtime execution

34. ReturnExecution

35. Transactional Control Flow 9 UPDATE ACT_RU_EXECUTION SET ACTIVITY_ID = ‘Wait 2’ Execution

37. Load existing execution

38. Pass data in (optional)

39. Take transition to “Send email”

40. Execute “Send email”

41. Take transition to “end”

42. Stop interpreting process

43. Delete runtime execution

44. ReturnExecution

45. Transactional Control Flow 11 DELETE FROM ACT_RU_EXECUTION WHERE ID_ = ? Execution

47. Task lists

48. JMS message send & receive

49. Web service send & receive

50. And… everything you can do in Java

52. Log every process instance and activity instance

53. Activities at business level

54. Statistics are valuable business intelligence

56. Showing you the nitty-gritty details

58. Thorough analysis is needed

59. All steps needs to be recorded in official documents

61. The mortgage process 17 = CMIS call

65. Business processes change

66. Activiti supports versioned process definitionsProcessInstanceprocessInstanceA = runtimeService.startProcessInstanceByKey(“mortgage”); repositoryService.createDeployment() .addClasspathResource(“mortgage-process.bpmn20.xml”) .deploy(); Process def “mortgage”, version = 1 ProcessInstanceprocessInstanceB = runtimeService.startProcessInstanceByKey(“mortgage”); Process def “mortgage”, version = 2

68. They execute according the original process definition

69. “Phase-out” strategy

70. New process instances

71. Default: latest deployed process definition

72. Instance migrationruntimeService.startProcessInstanceByKey(“process-key”); ProcessDefinitionprocDef = repositoryService.createProcessDefinitionQuery() .name(“myProcess”) .version(2) .singleResult(); runtimeService.startProcessInstanceById(procDef.getId()); Latest deployed Specific version

75. Start event can have a start form to capture this data

76. Activiti ExplorerFormInstance form = repositoryService.getStartFormInstance(“mortgage”);

80. Support for

81. Delegation to class

85. Specific service task shipped with Activiti29

87. So they should be tested just the same as your regular application code …

88. With unit tests !

89. Activiti supports both JUnit 3 and JUnit4 style of testing your business processes

90. And ships with a lot of convience for testing

91. Demo30 Pic from http://silverbackapp.com

93. But is just too cool not to share with you

94. Timers

95. Script support

96. Query API

97. Spring integration

98. Method expressions

99. JPA31

101. A timer boundary event can be attached to the boundary of any task or subprocess 32

103. Current execution(s) inside scope of event are destroyed and process continues following seq-flow going out the timer event33

105. Any JSR-223 compliant script language

106. Opens up powerful capabilities

107. Javascript, XPath, CMIS-script (?) <scriptTask id="theScriptTask" name="Execute script" scriptFormat="groovy"> <script> sum = 0 for (i in inputArray) { sum += i } execution.setVariable(“myVar”, sum) </script></scriptTask> 34

109. Powerful and uniform query API

110. Deployments and process definitions

111. Process instances and executions

112. History

113. Variables

114. 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); 35

116. Define and inject Activiti process engine and services

117. Leverage and integrate with Spring transaction management

118. Delegate to Spring beans in the process definition

119. Resource deployment and duplicate filtering for simplified development

120. Spring unit testing support36

122. Delegate to Spring beans<bean id=“printer” … 37

124. method expressions

125. method parameters

126. Variables, execution, …

127. First-class JPA support

128. Store JPA entity as process variable

129. Seamless integration of domain model with process

130. Only domain model reference is stored

131. Fetch/update is done in original data store38

132. Throwing it all together Update JPA entity Decision based on JPA entity property Spring bean Process variables 39
