Human Task Inline and stand-alone human tasks

Inline and stand-alone human tasks

You can implement a human task as part of the logic of a BPEL process, or independently of other processes.

If the task is implemented within a BPEL process, it is called an inline task. Otherwise, it is referred to as a stand-alone task.

• Stand-alone tasks
  Stand-alone tasks follow the service-oriented architecture (SOA) pattern and they are loosely coupled with the components that invoke them (to-do tasks), or the components that are invoked by them (invocation tasks). They can be wired to another component using the Service Component Architecture (SCA) infrastructure.
• Inline tasks
  Inline tasks are an integral part of the BPEL process. Inline tasks can be to-do tasks, invocation tasks, or administration tasks. Because collaboration tasks rely on the interaction between people and do not directly interact with processes, they cannot be inline tasks. Inline tasks are neither visible as SCA components (cannot be wired), nor are they reusable in other processes or activities.
