Hazelcast Persistence for Camunda (Community Extension)
Getting Started
In order to get started with Camunda and Hazelcast, you need to setup a Java Project which has the camunda-engine-hazelcast in the classpath. If you use Apache Maven this would include the following dependencies:
<dependencies>
<dependency>
<groupId>org.camunda.bpm.ext</groupId>
<artifactId>camunda-engine-hazelcast</artifactId>
<version>1.0.0-alpha1</version>
</dependency>
</dependencies>
Next, you create a Java Class with a Main Method configure and start Camunda:
public class Server {
public static void main(String[] args) {
ProcessEngine processEngine = new HazelcastProcessEngineConfiguration()
.buildProcessEngine();
try {
// your code goes here...
}
finally {
processEngine.close();
}
}
}
This starts up the Camunda Process Engine with an embedded Hazelcast Instance.
Once you have this set up, you can deploy a bpmn process:
// repository service allows managing deployments
final RepositoryService repositoryService = processEngine.getRepositoryService();
// create a new deployment of a simple workflow
repositoryService.createDeployment()
.addModelInstance("test-process.bpmn",
Bpmn.createExecutableProcess("testProcess")
.startEvent()
.receiveTask("waitForMessage")
.endEvent()
.done())
.deploy();
In the code example above, the BPMN process is created using the fluent dsl. Resulting process consists of a start event, a message receive task and an end event:
This process can be started like this:
final RuntimeService runtimeService = processEngine.getRuntimeService();
// start the process
ProcessInstance pi = runtimeService.startProcessInstanceByKey("testProcess");
// signal the process instance to continue
runtimeService.signal(pi.getId());
