SOAP, Enterprise JavaBeans, and Java Support for the Human Workflow Services

Table 34-1 lists the type of Simple Object Access Protocol (SOAP), Enterprise JavaBeans, and Java support provided for the task services. Most human workflow services are accessible through SOAP and remote Enterprise JavaBeans APIs. You can use these services directly by using appropriate client proxies. Additionally, the client libraries are provided to abstract out the protocol details and provide a common interface for all transports.

Table 34-1 Enterprise JavaBeans, SOAP, and Java Support

Service Name	Supports SOAP Web Services	Supports Remote Enterprise JavaBeans
Task Service: Provides task state management and persistence of tasks. In addition to these services, the task service exposes operations to update a task, complete a task, escalate and reassign tasks, and so on.	Yes	Yes
Task Query Service: Queries tasks for a user based on a variety of search criteria such as keyword, category, status, business process, attribute values, history information of a task, and so on.	Yes	Yes
Identity Service: Enables authentication of users and the lookup of user properties, roles, group memberships, and privileges.	Yes	No

User Metadata Service: Manages metadata related to workflow users, such as user work queues, preferences, vacation, and delegation rules.	Yes	Yes
Task Reports Service: Provides workflow report details.	Yes	Yes
Runtime Config Service: Provides methods for managing metadata used in the task service runtime environment.	Yes	Yes
Evidence Store Service: Supports storage and nonrepudiation of digitally-signed workflow tasks.	Yes	Yes
