Deleting a deployment will remove it from the DB. If you want to cascade deletion of a deployment to all the process instances of all the process definitions, use deleteDeploymentCascade. Starting a new process instance 5. Then a new process instance is started in that latest process definition. When a new version of the insurance claim process is deployed, all invocations of startProcessInstanceByKey will automatically switch to the newly deployed version.

Deleting a deployment will remove it from the DB. If you want to cascade deletion of a deployment to all the process instances of all the process definitions, use deleteDeploymentCascade. Starting a new process instance 5. Then a new process instance is started in that latest process definition. When a new version of the insurance claim process is deployed, all invocations of startProcessInstanceByKey will automatically switch to the newly deployed version.

With a key A new process instance can optionally be given a key. A business key must be unique within the scope of all versions of a process definition. Typically it is easy to find such a key in the domain of the business process.

For example, an order id or an insurance claim number. With a dot between process-key and execution-id. So execution created in the previous code snippet will have id ICL. If no user defined key is provided, the DB primary key is taken as the key. Typically in your application domain, finding such a key is not difficult.

By providing a user defined key, you can then compose the id of the execution, rather then performing a query based on the process variables - which is also more costly performance-wise.

With variables A map of named parameter objects can be provided when starting a new process instance. These parameters will be set as variables on the process instance between creation and start of the process instance.

Signalling a waiting execution When using a state activity, the execution or process instance will halt when it arrives in a state, waiting for a signal aka external trigger. The method signalExecution and alike can be used for that. Executions are referenced by an execution id String. In some cases, the execution that arrives in a state will be the process instance itself.

But that is not always the case. In case of timers or concurrency, a process is the root execution of a tree of executions. So you have to make sure that you signal the right path of execution.

In that event listener you can also obtain the exact execution id with execution. TaskService The primary purpose of the TaskService is to provide access to task lists. The code sample will show how to get the task list for the user with id johndoe.

The form needs to be able to read and write data related to the task. The logic is as follows: If a task has one outgoing transition without a name then: taskService. One transition has no a name and the other transition have a name: taskService. Candidates can be users or groups. Users can take tasks for which they are a candidate. Taking a task means that this user will be set as the assignee. After that, other users will be blocked from taking the task.

People should not work on a task unless they are assigned to that task. The user interface should display forms and allow users to complete tasks if they are assigned to it.

HistoryService During runtime execution of process instances, events are generated. And from those events, history information on both running and completed process executions are collected in the history tables. The HistoryService provides access to that information. See javadocs for more information on those methods. Sometimes there is a need to get complete list of nodes executed for a given process instance.

Sometimes execution id is different than process instance id, for instance when an activity has a timer then execution id will get additional suffix, which makes that node excluded from a result list while querying by execution id. ManagementService The management service is mostly used to manage the jobs.

See javadocs for more information. This functionality is also exposed through the jBPM web console. Developers who need to write company-specific queries can of course still rely on Hibernate. But for most use cases, the query API will be more then suffice. The result is also paged, and the first page of 50 results is given. Every service has operations of creating such unified queries eg.

Do check the Javadoc of the services to learn everything about the query API.
