Đặt phòng, Kinh doanh thông tin chuyến bay Quy trình và kinh doanh Thông tin hành lý quá trình. Chúng tôi sử dụng thiết kế BPEL của NetBeans IDE mà đi kèm với doanh nghiệp NetBeans Pack cho thiết kế các quá trình này. Khi chúng tôi có kinh doanh các quá trình, | Chapter 3 Summary In this chapter we have introduced the concept of a Service Engine and given an overview of the Service Engines installed with the NetBeans Enterprise Pack the BPEL Java EE SQL IEP and XSLT Service Engines . We ve learned that Service Engines provide business logic functionality to their clients can be consumers and or providers run within a Java Business Integration JBI Server expose their interfaces via WSDL communicate within an Enterprise Service Bus via messaging We ve also discussed some basic concepts about JBI such as the Normalized Message Router Service Assemblies and Service Units. We have a good understanding of JBI some of the problems with Enterprise Application integration and why JBI is useful. In the next chapter we extend our knowledge of JBI and SOA application development with NetBeans by describing another standard JBI component the binding component. 49 Binding Components In Chapter 3 we introduced the need for JBI and discussed JBI concepts and components Service Engines. In this chapter we will take a closer look at JBI components discuss binding component BC and look at the support that NetBeans Enterprise Pack provides for these components. In this chapter we will discuss The role of binding components in JBI Container NetBeans Support for binding components File BC SMTP BC SOAP BC JDBC BC Jms BC FTP BC Binding Components In Chapter 3 we discussed how Service Engines are pluggable components which connect to the Normalized Message Router NMR to perform business logic for clients. Binding components are also standard JSR 208 components that plug in to NMR and provide transport independence to NMR and Service Engines. The role of binding components is to isolate communication protocols from JBI container so that Service Engines are completely decoupled from the communication infrastructure. For example BPEL Service Engine can receive requests to initiate BPEL process while reading files on the local file system. It can .
