Introduction to BPEL

What is BPEL?
Markup language for composing a set of discrete
services into an end-to-end process flow
SalesDB
start

• 10 years of RD from MSFT and IBM
• SOAP but also Java, JCA
• Rich Flow Semantics
• Optimized Bindings
• XPATHXSLTXQuery
• WS-Security
• A Process is a Service

New in BPEL 2.0Improved data access

• Variable XPath Binding ( notation)
• makes BPEL variable data available in XPath
  expressions as XPath variables leading to
  simplified expressions (without requiring usage
  of bpwsgetVariableData).
• Message parts
• are available as a variable for each part and may
  be referenced as varX.partN. BPEL 2.0 also adds
  support for variables based on XSD complex types.

10
New in BPEL 2.0Improved data manipulation

• BPEL 2.0 enables complex XML transformations
  within BPEL processes by introducing
  bpeldoXslTransform().
• keepSrcElement to control whether the destination
  element name is overwritten
• inline variable initialization,
• extension assign to enable implementations to
  extend assign capabilities

11
New in BPEL 2.0New activities

• forEach, which executes the enclosed scope, in
  serial or parallel, a variable number of times.
• repeatUntil, which repeats enclosed scope until
  specified condition is true,
• extensionActivity, which improves the ability of
  BPEL implementations to provided extended
  activities

12
New in BPEL 2.0Enriched fault handling

• BPEL 2.0 improves fault handling by introducing
  finer grain knobs in the catch construct, and a
  rethrow activity,
• advanced fault handling features are also
  introduced including termination handler and
  exitOnStandardFault attribute on scopes.

13
New in BPEL 2.0Advanced message operations

• BPEL 2.0 introduces Join-style Correlation set to
  enable multi-start process scenarios.
• Local PartnerLinks
• initializePartnerRole to facilitate process
  binding during deployment

14
New in BPEL 2.0Syntax makeovers

• Many changes in BPEL 2.0 are syntactic in nature
• changes from switch to if-elseif-else,
• changes from terminate to exit
• different cases of compensate
• compensate
• compensateScope

15
Not in BPEL 2.0BPEL4People

• People Activities People can perform tasks
  assigned to them by business processes
• People Initiating Processes People can initiate
  processes such as Expense Report
• People Managing Business Processes Business
  processes may require intervention to move the
  process forward
• Transition between Human and Automated Business
  processes may change human activities to
  automated activities and vice versa
• Escalations Escalation mechanisms are needed to
  escalate tasks that are not performed within
  expected time
• Nomination Some situations may require
  performers to be assigned (nominated) on an
  instance basis (run time)

16

BPEL PM 10.1.3 Decision Service
23
BPM Rules - Usage Scenarios
Rules engines can be invoked as a Decision
Service from a BPEL process.

• Dynamic processing
• Intelligent routing
• Validation of policies within process
• Constraint checks
• Ad-hoc Workflow
• Policy based task assignment
• Various escalation policies
• Load balancing of tasks
• Business Activity Monitoring
• Alerts based on certain policies
• Dynamic processing based KPI reasoning

Decision Service (Rules)
Business Process (BPEL)
24
Decision Service - Concepts

• Enables users to easily wire any Rules engine
  with a BPEL process
• Key ideas
• Abstracts proprietary rule engine apis via a
  standard web service interface.
• Will work with any rules engine. Support for
  Oracle Business Rules and iLog JRules (BLAZE
  expected, others possible)
• Provides access to rules repository at design
  time (JDev) to enable user to browse rule sets
• Supports both stateless and stateful interaction
  patterns
• Example ExecuteFunction, AssertFacts, WatchFacts
  etc.
• Implementation Details
• Generates specific WSDL based on rule set being
  invoked
• Metadata about rule engine and repository
  captured in .decs XML file in BPEL project
• Supports both SOAP and WSIF bindings

BPEL PM 10.1.3 BPEL Test Feature
27
BPEL Test Framework

• Provides a mechanism that allows users to
  automate testing of their BPEL processes
• Emulate partners/services
• Verify process actions (assert)
• Calculate code coverage
• Supports both service and system faults
• Results integrated into BPEL Console as well as
  Ant-JUnit reports
• User experience
• Create test case driver file (export from audit
  trail)
• Deploy and run test cases via console or
  command-line
• View results, fix process logic and repeat

28
BPEL Test Framework

• 1. Create XML unit test driver from instance
  audit trail

29
BPEL Test Framework

• 2. Execute tests
