SOA and WS-BPEL: Composing Service-Oriented Architecture Solutions with PHP and Open-Source ActiveBPEL

 

Composing Service-Oriented Architecture Solutions with PHP and Open-Source ActiveBPEL

• Build Web Services with PHP
• Combine PHP Web Services into orchestrations with WS-BPEL
• Use better WS-BPEL to enable parallel processing and asynchronous communication
• Simplify WS-BPEL development with free graphical tool ActiveBPEL Designer

In Detail

When utilized within a Service-oriented Architecture (SOA), Web Services are part of a business process determining the logical order of service activities – logical units of work performed by one or more services. Today, the most popular tool for organizing service activities into business processes is Web Services Business Process Execution Language (WS-BPEL), a language defining an execution format for business processes operating on Web Services. While it is not a trivial task to define a business process definition with WS-BPEL from scratch, using a graphical WS-BPEL tool can significantly simplify this process.

Examples and practice are much more valuable than theory when it comes to building applications using specific development tools. Unlike many other books on SOA in the market, this book is not focused on architecture. Instead, through numerous examples, it discusses practical aspects of SOA and WS-BPEL development, showing you how to apply architecture in practice with the help of PHP, ActiveBPEL open-source engine, and ActiveBPEL Designer – powerful development tools available for free.

What you will learn from this book?

• Install and configure the software components required to build PHP Web Services and then combine them into WS-BPEL solutions
• Use PHP as the underlying technology for creating building blocks for SOAs
• Build data-centric services based on MySQL or Oracle Database XE
• Secure services built with PHP SOAP extension
• Combine fine-grained services built with PHP into coarse-grained ones with WS-BPEL
• Deploy WS-BPEL process services to ActiveBPEL open-source engine
• Simplify WS-BPEL development with ActiveBPEL Designer
• Implement asynchronous interactions between WS-BPEL processes

Approach

With the help of many examples, the book explains how to build Web Services with PHP, combine them into SOAs with WS-BPEL, and then deploy composite WS-BPEL-based solutions to the ActiveBPEL engine. The examples in this book are presented in a way that anyone can understand and apply.

Who this book is written for?

This book is suitable for anyone who wants to start building SOA applications using powerful tools available free of charge. It also will be useful for PHP developers willing to move towards Service-Oriented Architecture (SOA).

Readers need only a basic knowledge of SOA, BPEL, and Web Services; even a total beginner will be able to follow the examples, provided the required software components are installed on his or her computer. More experienced readers might use this book as a reference, focusing only on the chapters of interest.

Design, Build and Implement SOA Solutions with New Book on Oracle SOA Suite

Oracle SOA Suite Developer’s Guide is a new book from Packt that guides developers to use and apply the Oracle SOA Suite 10gR3 in the implementation of SOA applications. Written by expert developers in SOA BPEL, Antony Reynolds and Matt Wright, this book walks the reader through key SOA design considerations with the help of a working example of an online auction site (oBay).

This book guides the reader through a tutorial of the core components that make up the Oracle SOA Suite; namely the Oracle Service Bus, BPEL Process Manager, Human Workflow, Business Rules, and Business Activity Monitoring, thus helping the reader to find the best way to combine or use all of these different components to implement a real-world SOA solution.

Developers will learn to build implementation-agnostic services using the Oracle Service Bus. They will be shown how to assemble services in order to build composite services and long-running business process. The readers will be taught how to use business rules to externalize “decision points” in a BPEL process, and will be able to incorporate Human Workflow into their processes to provide greater agility.

This book will help users secure and administer SOA applications using Web Service Manager, and will teach them to observe the protocols available in addition to SOAP over HTTP for invoking Web Services. Readers will also learn to design their Web Service contracts for interoperability and maintainability, thus building new business services.

Technical architects and developers working with SOA will find this book useful. This book is out now and is available from Packt. For more information, please visit http://www.packtpub.com/developers-guide-for-oracle-soa- …

BPEL4People fails to address human interaction requirements in business software, says Procession

Last month, a group of large software technology companies produced the specification of how to better reflect human interaction in business software.

This move had been prompted by a white paper, produced jointly by IBM and SAP in 2005, which recognised that the existing enabling technology, called Business Process Execution Language (BPEL), was unable to deliver the human interaction requirements of the relationship. The new specification is an extension of BPEL – known as BPEL4People.

Commenting on this development, David Chassels, CEO of Procession, the developer of people/ task driven and goal directed software, said: “This is a step in the right direction but the core design of BPEL does not reflect well how people interact and how processes work in real life.”

In Chassels’ view, BPEL4People recognises that business process management (BPM) is a ‘production line’ for service delivery but that service is driven by human interaction and, at certain points, possibilities exist for such eventualities as:
•   End users’ personal preferences on how to achieve the goal
•   The multi-branching and asynchronous capability of the business process, with both tributaries and distributaries to and from the process
•   Errors and exceptions arising at unknown points in the process

”According to convention, whatever their people do in their work should adhere to some rules and, today, proof that these rules are adhered to,” Chassels continued. ”The integrity of that data needs to be maintained although it is created in an unstructured arena.

“These may seem like conflicting requirements but, if software is to truly support business, this apparent conflict needs to be addressed,” Chassels added.

“The other major issue is to close the divide between ‘business’ and ‘IT’. The BPEL4People specification does little to give comfort in this respect.

“I believe that a complete rethink is required,” he said. “Trying to adapt old technology-driven thinking will just not deliver.

“This idea has driven Procession to pioneer focusing on putting people first and removing technology complexity to allow the business to regain control over its people and processes.

“It has taken over ten years R&D and working with early adopters to produce the key to how to achieve the seemingly impossible,” he revealed. “This has helped us to recognise that there are few task types that can handle any eventuality in business.

“By separating business logic from technology driven delivery mechanisms – the internet being the latest – we can deliver on all the required attributes as described. We build applications using a graphical interface that does not require an interpretation language such as BPEL or the compilation of code.

“There are a number of core design principles that have allowed us to achieve our objectives,” Chassels explained. “These include being data centric; developing a dynamically created user form recognising people roles task and data; having flexible linking capability that also allows time and rules to be recognised, and producing a simple intuitive graphical designer that allows business professionals to control the building of an application from ‘end to end’.

“Procession represents a challenging alternative to the mindset of the established giants of our industry,” claimed Chassels, “although Microsoft now appears to be following the core design philosophy and trying to patent it in the US.  This could be a real ‘David and Goliath’ confrontation!”
