Engine and the services objects are thread safe.So you can keep a reference to 1 of those for a whole server.Process. Engineprocess.EngineProcess.

Engine will initialize and build a process engine the first time it is called and afterwards always return the same process engine.Proper creation and closing of all process engines can be done with Process.Engines. init and Process.Engines. destroy.The Process.

For all activiti context.Spring way First the Spring application context is created and then the process engine is obtained from that application context.All services are stateless.This means that you can easily run Activiti on multiple nodes in a cluster, each going to the same database, without having to worry about which machine actually executed previous calls.Any call to any service is idempotent regardless of where it is executed.The Repository. Service is probably the first service needed when working with the Activiti engine.This service offers operations for managing and manipulating deployments and process definitions.Without going into much detail here, a process definition is a Java counterpart of BPMN 2.It is a representation of the structure and behaviour of each of the steps of a process.A deployment is the unit of packaging within the Activiti engine.A deployment can contain multiple BPMN 2.The choice of what is included in one deployment is up to the developer.It can range from a single process BPMN 2.The Repository. Service allows to deploy such packages.Deploying a deployment means it is uploaded to the engine, where all processes are inspected and parsed before being stored in the database.From that point on, the deployment is known to the system and any process included in the deployment can now be started.Furthermore, this service allows to.Query on deployments and process definitions known to the engine.Suspend and activate deployments as a whole or specific process definitions.Suspending means no further operations can be done on them, while activation is the opposite operation.Retrieve various resources such as files contained within the deployment or process diagrams that were auto generated by the engine.Retrieve a POJO version of the process definition which can be used to introspect the process using Java rather than xml.While the Repository.Service is rather about static information i.Runtime. Service is quite the opposite.It deals with starting new process instances of process definitions.As said above, a process definition defines the structure and behaviour of the different steps in a process.A process instance is one execution of such a process definition.For each process definition there typically are many instances running at the same time.The Runtime. Service also is the service which is used to retrieve and store process variables.This is data which is specific to the given process instance and can be used by various constructs in the process e.The Runtimeservice also allows to query on process instances and executions.Executions are a representation of the token concept of BPMN 2.Basically an execution is a pointer pointing to where the process instance currently is.Lastly, the Runtime.Service is used whenever a process instance is waiting for an external trigger and the process needs to be continued.A process instance can have various wait states and this service contains various operations to signal the instance that the external trigger is received and the process instance can be continued.Tasks that need to be performed by actual human users of the system are core to a BPM engine such as Activiti.Everything around tasks is grouped in the Task.Service, such as.Querying tasks assigned to users or groups.Creating new standalone tasks.These are tasks that are not related to a process instances.Manipulating to which user a task is assigned or which users are in some way involved with the task.Claiming and completing a task.Claiming means that someone decided to be the assignee for the task, meaning that this user will complete the task.Completing means doing the work of the tasks.Typically this is filling in a form of sorts.The Identity. Service is pretty simple.It allows the management creation, update, deletion, querying, of groups and users.It is important to understand that Activiti actually doesnt do any checking on users at runtime.For example, a task could be assigned to any user, but the engine does not verify if that user is known to the system.This is because the Activiti engine can also be used in conjunction with services such as LDAP, Active Directory, etc.The Form. Service is an optional service.Meaning that Activiti can perfectly be used without it, without sacrificing any functionality.This service introduces the concept of a start form and a task form.A start form is a form that is shown to the user before the process instance is started, while a task form is the form that is displayed when a user wants to complete a form.Activiti allows to define these forms in the BPMN 2.This service exposes this data in an easy way to work with.But again, this is optional as forms dont need to be embedded in the process definition.The History. Service exposes all historical data gathered by the Activiti engine.When executing processes, a lot of data can be kept by the engine this is configurable such as process instance start times, who did which tasks, how long it took to complete the tasks, which path was followed in each process instance, etc.This service exposes mainly query capabilities to access this data.The Management. Service is typically not needed when coding custom application using Activiti.It allows to retrieve information about the database tables and table metadata.Furthermore, it exposes query capabilities and management operations for jobs.Jobs are used in Activiti for various things such as timers, asynchronous continuations, delayed suspensionactivation, etc.Later on, these topics will be discussed in more detail.The Dynamic. Bpmn.Service can be used to change part of the process definition without needing to redeploy it.You can for example change the assignee definition for a user task in a process definition, or change the class name of a service task.For more detailed information on the service operations and the engine API, see the javadocs.Exception strategy.The base exception in Activiti is the org.Activiti. Exception, an unchecked exception.This exception can be thrown at all times by the API, but expected exceptions that happen in specific methods are documented in the the javadocs.For example, an extract from Task.Service 1. 6 Called when the task is successfully executed.Id the id of the task to complete, cannot be null.Activiti. Object.Not. Found. Exception when no task exists with the given id.Stringtask. Id In the example above, when an id is passed for which no task exists, an exception will be thrown.Also, since the javadoc explicitly states that task.Id cannot be null, an Activiti.Illegal. Argument.Exception will be thrown when null is passed.Even though we want to avoid a big exception hierarchy, the following subclasses were added which are thrown in specific cases.Margin Call.
