Core Services: Execution Server

Client Applications ESBs Partner

ServicesMobileClients

● Centralized Execution Server

● REST, JMS and Native Java Interfaces out of the box

● Native Java Client that interfaces through REST

● Clusterable, Scalable Server

●

10

Core Services: Development Repository

● GIT Based – Universally accepted

● Enterprise features like tagging, branching etc

● No repository migration hassles● Browse any GIT repository● Import and Export● Indexed searching

11

Knowledge Management

12

Choice of Tools

Business User Friendly – Web Based Developer Friendly – IDE Based

13

Core Services: Integration with FSW

Switchyard● Defined SY task in Designer

● Direct invocation of SY services from Process

● SY can instantiate a business process

● SY can signal a process

● SY can execute a task

BPM Lifecycle - Deploy

Business Assets

Core Services

25

Deploy: Packaging, Deployment Repository

● Maven Packages● Build – Creates a kjar – Includes all assets – process

definitions, classes, forms, images etc● Deploy – Deploy to a Maven repo● Applications can pull from Maven Repo● Dependency management with other libraries – Share

libraries● Integrate with SRAMP – Governance in multi stage● Configure Maven Repo location

26

Deploy: How Deploy Works

27

Migrating from 5.3 to 6

● Things to Consider in migration● New development repository – JCR to GIT● New Packaging – PKG to Maven JARs● New APIs – Knowledge APIs to KIE

● Legacy KIE APIs are still supported● All assets – process defs, DRLs, Decision Tables,

models work as is

Under the hoods

New Core Features

● RuntimeManager:● Session + TaskService management

● CDI integration● Execution server● Remote API

● REST, JMS● Deployment using kjar

41

RuntimeManager

● Access to KieSession and TaskService● Hides setup complexity

● Manages sessions● Singleton session● Session per request● Session per process instance

KieSession

TaskService

Runtim

eManager

42

RuntimeManager Example

RuntimeManager manager = RuntimeManagerFactory.Factory.get() .newPerProcessInstanceRuntimeManager(environment);

RuntimeEngine runtime = manager.getRuntimeEngine( ProcessInstanceIdContext.get(id));

KieSession ksession = runtime.getKieSession();// do something here, e.g.ksession.startProcess(“org.jbpm.hello”);

manager.disposeRuntimeEngine(engine);manager.close();

43

jBPM Services (CDI)

● Inject services into your CDI environment@Inject @Singleton RuntimeManager singletonManager;@Inject TaskService taskService;

● Configure (@Produces) EMF, environment, usergroupcallback

44

jBPM Execution Server

● Execute process and task commands● Through UI● Remote API

● Clustered environment● High Availability● Load balancing

46

Remoting

● KieSession and TaskService● Possibly more later● Uses RuntimeManager

● Using REST or JMS● JAXB + JSON

● Remote client using existing interfaces

47

REST APIhttp://server.address:port/{application-id}/rest/ runtime {id: [a-zA-Z0-9-]+} // deploymentId process {id: [a-zA-Z0-9-]+} start * start process [POST] instance {id: \\d} * process instance details [GET] signal * signal event [POST] abort * abort process instance [POST] signal {id: [a-zA-Z0-9-]+} * signal event [POST] workitem {id: \\d} complete * complete work item [POST] abort * abort work item [POST] execute * execute the given command [POST] task {id: \\d+} * task details [GET] activate * activate task claim * claim task [POST] // etc.. execute * execute the given command [POST] query * task query

48

Command Serialization

● JAXB serialization of commands● e.g. Start task

<command-message> <deploymentId>test</deploymentId> <ver>1</ver> <start-task> <taskId>1</taskId> <userId>krisv</userId> </start-task></command-message>

49

REST Client Example

RuntimeEngine runtimeEngine = new RemoteRestSessionFactory( "org.jbpm:HR:1.0”, “http://localhost:8080/jbpm-console", AuthenticationType.BASIC, "krisv", "krisv") .newRuntimeEngine();

engine.getKieSession().startProcess("org.jbpm.humantask");

engine.getTaskService().start(1, "krisv");
