Past and future generations of SOA BPEL ESB I am not selling middleware, so I do not have to advocate the concept and principle of SOA.I am not preparing to write an SOA book, so I don't have to chew on it when I write my blog. This article involves SOA, SCA, SDO, workflow, BPEL, ESB, message middleware, WebService, EAI, analysis and design methods, object-oriented, and many components-oriented technologies

Since Oracle released the Enterprise Service Bus (ESB) as part of the SOA suite, many people are curious about the added value and use of the ESB compared to the full self-contained implementation within the Oracle BPEL process manager alone. One of its advantages is the ability to transparently virtualize service endpoints to its users, providing conversions fr

Message relevance is a BPEL4WS mechanism that allows a process to participate in stateful sessions. Message relevance can be used for multiple purposes. For example, it can be used to match regular customers or known customers to long-running business processes.When a message arrives for a Web Service implemented by BPEL, the message must be sent to an appropriate place-either to a new instance of the process or to an existing instance..The problem to

It is fully known as business process execution language, namely, the Business Process Execution language. It is a programming language written in XML. Used to automate business processes, also known as wsbpel and BPEL4WS. It is widely used in Web service-related project development. It has the advantages of portability and effective protection of investment. BPEL is a formal protocol language used to automate business processes. The process of writin

How does one orchestrate web services through BPEL? Some companies call it a web services workflow, which means that the basic web services protocol stack soap/WSDL/UDDI has been used. BPEL is used to construct the decision chain or workflow of these web services. To build as many Web Services-based business processes as possible and bond them together with BPEL,

Introduction Based on WebService, an SOA (Service Oriented Architecture) architecture is used to establish an enterprise business system solution, analyzing and clarifying the business process of the enterprise and defining the Web service to fit the granularity. When it comes to cross departmental, end-to-end business process dynamic integration, these Web services need to be combined sequentially to achieve business process integration methods and technologies. Therefore, under the SOA archit

Loan approval case for BPEL (2) We copy the business process definition of this example below for instructions:Targetnamespace = "http://acme.com/loanprocessing"Xmlns = "http://schemas.xmlsoap.org/ws/2003/03/business-process"Xmlns: lNS = "http://loans.org/wsdl/loan-approval"Suppressjoinfailure = "yes"> Partnerlinktype = "lNS: loanpartnerlinktype"Myrole = "loanservice"/>Partnerlinktype = "lNS: loanapprovallinktype"Partnerrole = "approver"/>Partnerlinkt

In BPEL, the relationship between several basic elements is mainly defined by the following key labels: On the other hand, the WebService is not directly associated with partlink, which adds another layer, namely This design allows you to flexibly configure business processes and combine the same ws services in different businesses, you can change role to myrole or partnerrole to define the position of the Service in the business, in the design o

Abstract process BPEL is not only used to specify an executable process, but you can also use it to specify an abstract process. Abstract processes are primarily used to define messages and possible orders that a partner can exchange for business purposes and its other partners. It can be viewed as an external view of the executable business process, omitting some of the internal execution details and complexities. In
