BPEL Background & Motivation
The Base: Service Platform Messaging Quality  of Service Transport Description Transports Interface + Bindings Composite XML Non-XML Security Policy Discovery, Negotiation, Agreement Atomic Orchestration Protocols State Components Reliable Messaging Transactions
The Base: Web Services Messaging Quality  of Service Transport Description HTTP, SMTP, XMPP, TCP/IP, FTP, Tuple Spaces,… WSDL Composite SOAP, WS-A JMS, RMI/IIOP WS-Security* WS-Policy* UDDI, WS-A, WS-MEX, WSIL Atomic BPEL WS-C, WS-CDL,  BPEL4Chor WSRF Components WSRM WS-AT, WS-BA,…
Why Orchestration? ??? To achieve a business goal, you often need more than one service… Which to use, in which order, how to use them?
Web Service Orchestration BPEL!
What is BPEL? Business Process Execution Language, since  4/07 OASIS Standard High-level programming language Recursive Model BPEL has native support for Long running processes Scalability Concurrency Message and instance correlation Fault handling Compensation based recovery Phoenix behaviour Most important: BPEL is standard and supported by most important vendors. Defined Execution Semantics Abstract Processes (protocols, “views” on internal processes)
What is BPEL not? “ BPEL is block-structured only and therefore not usable for business users” “ BPEL does not support multiple transport protocols” Look at WSDL “ BPEL interactions are only synchronous” Look at WSDL “ Look at this ugly XML, business people won’t understand this cumbersome stuff” Not meant to be hand-written, use tools! BPEL is not a modeling notation
BPEL’s Foundation Web Services WSDL 1.1 – abstract part (concrete part    ESB) (SOAP) (WS-Addressing) Flow Control Block structured (nested blocks) Graph-based flows (using <flow>) Data Model W3C XML Schema 1.0 XML InfoSet XPath 1.0 XSLT 1.0
BPEL 2.0 Activities compensateScope compensate Basic Activities Structured Activities receive reply invoke assign validate throw rethrow exit wait empty extensionActivity forEach sequence 2. N. 1. … flow B C A while c repeatUntil c if-elseif-else c1 c2 … 2. N. 1. … pick … A M2 M1 scope
Partner Links / Partner Link Types process partner link partner link type Peer-to-peer conversational partner relationship “ I expect from my partner  an implementation of this!” Define “contract channels” between partners -  Key concept to enable asynchronous messaging! WSDL port type myRole Provided port type WSDL port type partnerRole Required port type receive Inbound request – service provided by the process invoke Outbound request – service required by the process
Properties and Correlation Sets How to identify stateful instances via stateless WS interfaces? A process instance is assigned one or more keys Business data is used as key, e.g., customerID A key can be compound, e.g., (customerID, orderNumber) WS-BPEL calls a key a correlation set – it is used to correlate an incoming message with a process instance Process 4 (0123,15) Process 3 (0815,42) Process 2 (4711,37) Process 1 (0815,12) 0815 42 Message 2 customerID orderNumber 4711 37 Message 1
Fault Handling & Compensation Fault Handling Like in Java, enables alternative execution paths Can trigger compensation Compensation ACID Transactions are not applicable when dealing with long running processes Compensation-based recovery Compensation Handler can reverse the work performed by an already completed scope Compensation Handler is “installed” after successful execution of a scope Compensation can only be triggered by fault/compensation/termination handler of the enclosing scope
Fault and Compensation Handling
Modelling Styles Block structured modelling Nesting of structured activities Use of  <flow>  activity for parallelism Graph based modelling <flow>  activity with links Transition conditions & join conditions Dead-Path-Elimination Acyclic graph to ensure sound execution semantics Loops can be realized with  <while>  /  <repeatUntil>  /  <forEach> Not supported by Sun & Oracle! t 1 t 2 j
Modeling Styles: Example
BPEL4People/WS-HT Support for Human Tasks Standardization Committed at OASIS currently being formed BPEL-SPE Support for sub-processes Autonomy is key BPELJ Use Java in BPEL Activities Use Java types in BPEL BPEL4SWS Support for Semantic Web Services (Service Discovery) Data Mediation BPEL light WSDL-less BPEL Is about message exchanges BPEL JS/E4X Use JavaScript/E4X for variable assignments BPEL Extensions
BPEL Open Source Orchestra
Eclipse BPEL Designer BPEL 2.0 Design Tool … …  all standard activities are supported  No full support of extensibility mechanisms  Partial support of abstract BPEL BPEL 2.0 Validator included Synchronized graphical & XML modelling mode Prototypical graphical process compare
BPELUnit BPELUnit is a test framework like JUnit is for Java http://www.bpelunit.net Supports BPEL specifics: Web service mocking Transparent (un-)deployment Test Coverage calculation Most functionality independent of BPEL Engine Front-ends for Eclipse, Ant, and command-line
Testing Testing is the  execution  of a program  with the  intend to find defects find defects also means: systematically in a repeatable way in our case: automate it! Simulation is  not  Testing Testing also includes the application server, JVM, BPEL Engine, Database configuration, ... Simulation uses another &quot;target engine&quot;
Test Structure BPEL BPELUnit Real Services deploy <soap> <soap> <soap> <soap> Client Mock A Mock B <soap> undeploy Eclipse Ant Command Line Deployer (optional)
BPEL Execution: Apache ODE BPEL 1.1 and 2.0 supported Fast and scalable process engine Modular design & embeddable 3 deployment targets supported Web container (Axis2) JBI (ServiceMix) SCA (Tuscany) Implicit Message Correlation XPath 1.0 & 2.0, XQuery Management and Auditing Backed by Intalio & Red Hat
Tammo van Lessen (IAAS, Uni Stuttgart) & Simon Moser (IBM) Demo
Demo schedule Open & Explain Fahrschulservice (v1) Run Tests (3 tests) Tests are green Verbal: New func required, create Testcase  Open pre-defined new Testcase (testcase 4) Run all 4 Tests against v1  One test is red Verbal: Analyse, find and eliminate problem Open & Explain prepared process (v2) Show Processes in Process Compare View Run tests again against v2  Tests are green
Is BPEL dead? Not really! BPMN 2.0 is still under development and not as mature as BPEL BPMN 2.0 adds even more abstraction and makes it more difficult to bring models to  execution It‘s a matter of time!
Q&A Thank you for your attention!

  • 7. Why Orchestration? ??? To achieve a business goal, you often need more than one service… Which to use, in which order, how to use them?
  • 9. What is BPEL? Business Process Execution Language, since 4/07 OASIS Standard High-level programming language Recursive Model BPEL has native support for Long running processes Scalability Concurrency Message and instance correlation Fault handling Compensation based recovery Phoenix behaviour Most important: BPEL is standard and supported by most important vendors. Defined Execution Semantics Abstract Processes (protocols, “views” on internal processes)
  • 10. What is BPEL not? “ BPEL is block-structured only and therefore not usable for business users” “ BPEL does not support multiple transport protocols” Look at WSDL “ BPEL interactions are only synchronous” Look at WSDL “ Look at this ugly XML, business people won’t understand this cumbersome stuff” Not meant to be hand-written, use tools! BPEL is not a modeling notation
  • 11. BPEL’s Foundation Web Services WSDL 1.1 – abstract part (concrete part  ESB) (SOAP) (WS-Addressing) Flow Control Block structured (nested blocks) Graph-based flows (using <flow>) Data Model W3C XML Schema 1.0 XML InfoSet XPath 1.0 XSLT 1.0

  • 13. Partner Links / Partner Link Types process partner link partner link type Peer-to-peer conversational partner relationship “ I expect from my partner an implementation of this!” Define “contract channels” between partners - Key concept to enable asynchronous messaging! WSDL port type myRole Provided port type WSDL port type partnerRole Required port type receive Inbound request – service provided by the process invoke Outbound request – service required by the process
  • 14. Properties and Correlation Sets How to identify stateful instances via stateless WS interfaces? A process instance is assigned one or more keys Business data is used as key, e.g., customerID A key can be compound, e.g., (customerID, orderNumber) WS-BPEL calls a key a correlation set – it is used to correlate an incoming message with a process instance Process 4 (0123,15) Process 3 (0815,42) Process 2 (4711,37) Process 1 (0815,12) 0815 42 Message 2 customerID orderNumber 4711 37 Message 1
  • 15. Fault Handling & Compensation Fault Handling Like in Java, enables alternative execution paths Can trigger compensation Compensation ACID Transactions are not applicable when dealing with long running processes Compensation-based recovery Compensation Handler can reverse the work performed by an already completed scope Compensation Handler is “installed” after successful execution of a scope Compensation can only be triggered by fault/compensation/termination handler of the enclosing scope
  • 17. Modelling Styles Block structured modelling Nesting of structured activities Use of <flow> activity for parallelism Graph based modelling <flow> activity with links Transition conditions & join conditions Dead-Path-Elimination Acyclic graph to ensure sound execution semantics Loops can be realized with <while> / <repeatUntil> / <forEach> Not supported by Sun & Oracle! t 1 t 2 j

  • 22. BPELUnit BPELUnit is a test framework like JUnit is for Java http://www.bpelunit.net Supports BPEL specifics: Web service mocking Transparent (un-)deployment Test Coverage calculation Most functionality independent of BPEL Engine Front-ends for Eclipse, Ant, and command-line
  • 23. Testing Testing is the execution of a program with the intend to find defects find defects also means: systematically in a repeatable way in our case: automate it! Simulation is not Testing Testing also includes the application server, JVM, BPEL Engine, Database configuration, ... Simulation uses another &quot;target engine&quot;

  • 28. Is BPEL dead? Not really! BPMN 2.0 is still under development and not as mature as BPEL BPMN 2.0 adds even more abstraction and makes it more difficult to bring models to execution It‘s a matter of time!
