chúng tôi tạo ra các module JBI để họ có thể được triển khai như một hội đồng dịch vụ trong Công cụ BPEL. Chúng tôi sử dụng module ứng dụng hỗn hợp của NetBeans để xây dựng các ứng dụng triển khai. Căn cứ vào nhu cầu, chúng ta có thể sử dụng CASA Editor để chỉnh sửa mô tả triển khai các ứng dụng hỗn hợp. | BPEL Designer Understanding BPEL Projects NetBeans BPEL Designer lets you to create and deploy BPEL processes which are compliant with the WS-BPEL specification. To perform these actions you need to create a BPEL module which is a NetBeans project type. The BPEL Designer provides a complete environment to enable you to quickly and efficiently orchestrate web services. NetBeans IDE provides a BPEL runtime plug-in that provides the standard BPEL runtime capability. The BPEL runtime that the IDE provides is a framework for the execution content of BPEL specifically compiling BPEL validating BPEL and assembling composite application descriptors. The BPEL runtime runs inside the Sun Java System GlassFish Application Server which provides a container for the JBI suite. Runtime services for executing BPEL-based applications are provided by the BPEL Service Engine which is a component of the JBI server. Refer to Chapter 3 on Service Engines . The BPEL Service Engine is started together with the Application Server. Thus before deploying and test running a Composite Application project you must make sure that the Application Server is started. 78 Chapter 5 BPEL Views You can perform source level editing as well as visual designing through the views provided by the BPEL Designer. The BPEL Designer will perform round-trip two-way engineering to ensure that the Design view and Source view remain synchronized with each other. The IDE will automatically re-parse the BPEL source file and rebuild the diagram every time you edit the BPEL file through the Source view. BPEL Design view is the default view and it is the view that gets invoked whenever you create a new BPEL module. To switch to the corresponding place in the Source view right-click an element in the Design view and select Go to Source Alt-O . Source and Design View are always in-sync. 79 BPEL Designer Design View The Design view is the diagram view. The Design view and the Source view are fully synchronized to do .
