Service Orchestration with BPEL

This three-day training "Service Orchestration with BPEL" focuses on using BPEL (Business Process Execution Language) for web service orchestration in Service-Oriented Architecture (SOA). Participants will learn to design, implement, and manage complex business processes using BPEL.

Required Participant Preparation

Knowledge of SOA and web services fundamentals
Programming experience (XML and Java preferred)

Benefits

Ability to design and implement business processes in BPEL
Of BPEL's role in SOA architecture
Capability to integrate various web services into coherent processes
Knowledge of best practices in service orchestration

Who is this training for?

SOA developers

System architects

System integration specialists

Business analysts with technical experience

Training program

Introduction to BPEL — history, purpose language, roles BPEL in architecture SOA, comparison orchestration with choreography services
Structure and syntax documents BPEL — przestrzenie nazw, elementy process, partnerLinks, portTypes, linking with WSDL
Defining processes business — activity basic (invoke, receive, reply, assign), sekwencje and flows
Handling zmiennych in BPEL — types zmiennych, inicjalizacja, copying data (assign/copy), expressions XPath
Correlations in BPEL — zestawy korelacji, properties korelacji, routing messages to proper instancji process
Exercises: creating pierwszego process BPEL — definicja WSDL, partnerLinks, prosty invoke/receive/reply flow

Advanced konstrukcje control — loops (while, repeatUntil, forEach), warunki (if/else, switch), parallelism (flow, links)
Scope and exception handling — faultHandlers, catch/catchAll, throw/rethrow, mechanizm propagacji errors
Compensation in BPEL — compensationHandlers, compensate, compensateScope, patterns transactions long-running
Handling events — eventHandlers, onMessage, onAlarm, timeouts and patterns asynchroniczne
Integration BPEL with services webowymi SOAP — bindings, style dokumentu, handling headers SOAP
Exercises: implementation process with handling exceptions, compensation and parallel flow

Integration BPEL with services REST — adaptery, transformacje JSON/XML, patterns integracyjne
Implementing processes BPEL — configuration silnika BPEL, deployment descriptors, wersjonowanie processes
Monitoring and debugging processes — tracking instancji, logs, tools diagnostyczne, metrics performance
Najlepsze praktyki i wzorce projektowe — wzorce orkiestracji (scatter-gather, sequential convoy, racing), antywzorce
Management procesami in environment production — migration instancji, handling wersji, performance and scaling
Final exercises: deployment and monitoring of a complete BPEL process integrating multiple web services
