Introduction to BPEL


What is BPEL?

• Business Process Execution Language• XML-based markup language for composing

a set of discrete services into an end-to-end process flow

• 10+ years of research and development from Microsoft (XLANG) and IBM (WSFL, FDML)

• Consumes and orchestrates WSDL-based services

• The glue that binds web services

• BPEL processes expose a WSDL interface• A process flow is automatically a service

Gartner believes that BPEL will

emerge as the leading industry

standard for Web service

orchestration and coordination

of business processes.

- David Smith, Research Vice President

and fellow, Gartner

BPEL is the future of the

integration space in my view…

Why? Because the value is so

much higher when you provide

not only a way to integrate

applications, but also a way to

create services from them and put

them into business processes

- John Rymer, Vice President, Forrester

Research, Inc.


Strengths of BPEL

• Orchestrates services• Designed for long running processes• Built-in support for asynchronous interaction• Fault handling and compensating transactions

• Extensible

• Parallel flows• Conditional branching


Based on standards

• Uses and extends the web services model• WSDL for defining the interface• XML and WSDL typed variables• SOAP for communication

• XML Schema for definitions

• XPath for data querying

• XSLT for transformations

• WS-Addressing


… And open

• Web services / SOAP interface• Public Java API

• Used internally as well• Example: Console

Summary of Workflow Features

Task Assignment• Users• Roles• Groups

Task routing• Declarative patterns• Ad-hoc routing• Document based routing• Complex routing with business

rules

Notifications• Declarative specification of:

• When – assigned, expired, …• Who – assignee, manager, …

• Email, Voice, Pager, SMS

Management Rules• Escalation, Expiration• Delegation, Vacation

rules• Work load balancing

Reports, Audit Trails, …

• Productivity and distribution reports

• Complete history and audit trail

Worklist Application• Profile based – assignee,

supervisor, group owner, process owner

• Available as portlets• Completely customizable• Web Services and Java API

Identity Management• Roles and Org. Hierarchy• Integrates with OID,

LDAP, JAZN; custom plug-ins

Task Forms• ADF based task forms• Auto-generated, user

defined• Task Data controls• MS Office integration


Features: BPEL PM 11g - WorkflowADF task flow for task forms

ADF enables sophisticated task display forms using RCF components, can create multi-page forms

Auto generate ADF task forms.

New Out of the box Worklist application

Based on rich client framework (JSF)
