1 概述 　　企业服务总线（Enterprise Service Bus，缩写 ESB），是SOA面向服务架构的骨干，在完成服务的接入、服务间的通信和交互基础上，提供安全性、可靠性、 高性能的服务能力保障。采用 SOA 架构，基于ESB总线进行企业异构应用集成，可以有效降低应用系统、各个组件及相关技术的耦合度，消除应用系统点对点集成瓶颈，降低集成开发难度，提高复用，增进系统开发和运行效率，便于业务系统灵活重构、敏捷适应业务及流程变化。 　　本文对企业服务总线ESB集成项目中，基于AEAI ESB实现异构系统集成的相关规范、标准进行阐述、明确，为项目开展以及后续完善扩展提供技术参考和依据。 2 功能特点 　　AEAI ESB作为数通畅联公司的企业应用集成产品，主要用来实现异构系统（如：不同的数据库、消息中间件、ERP或CRM等）之间的资源整合，实现互连互通、数据共享、业务流程协调统一等功能，构建灵活可扩展的分布式企业应用。 　　相比传统的企业应用集成软件平台，AEAI ESB是一个全新的符合SOA架构的应用服务整合平台，是基于大量集成实践经验不断完善、用于构建可管理、可扩展及经济高效的EAI技术解决方案。 图1.基于AEAI ESB总线的企业应用集成模式 　　AEAI ESB提供了从企业应用集成的设计、开发、部署，到运行、管理、监控各个生命周期阶段的工具。它提供的图形化

1 背景概述 由于在项目中需要多次调用webservice服务，本文主要总结了一下java调用WebService常见的6种方式，即：四种框架的五种调用方法以及使用AEAI ESB进行调用的方法。 2 预期读者 数通畅联内部员工 广大计算机爱好者 3 名词解释 Web Service也叫XML Web Service： WebService是一种可以接收从Internet或者Intranet上的其它系统中传递过来的请求，轻量级的独立的通讯技术。是通过SOAP在Web上提供的软件服务，使用WSDL文件进行说明，并通过UDDI进行注册。 XML：(Extensible Markup Language)扩展型可标记语言。面向短期的临时数据处理、面向万维网络，是Soap的基础。 Soap：(Simple Object Access Protocol)简单对象存取协议。是XML Web Service 的通信协议。当用户通过UDDI找到你的WSDL描述文档后，他通过可以SOAP调用你建立的Web服务中的一个或多个操作。SOAP是XML文档形式的调用方法的规范，它可以支持不同的底层接口，像HTTP(S)或者SMTP。 WSDL：(Web Services Description Language) WSDL 文件是一个 XML 文档，用于说明一组 SOAP 消息以及如何交换这些消息

1 引言 电子商务是一种新兴的、处于发展过程中的现代商务方式，从95年来得到了迅速发展，显现了巨大的现代商业价值。1997年欧洲、美国、新加坡等许多国家政府发表了电子商务发展纲要，其目的是引导全球电子商务的自由竞争和健康发展，大力推动电子商务的实践。我国政府的发展纲要也将在近期出台，促进我国企业适应国际化的发展、参与国际竞争。有理由相信，在21世纪，电子商务将逐渐成为社会生活的主要方式，也将成为数字化社会的基础。 电商较传统行业，在物流、客户、订单管理上有着更细化、更高的要求，比如物流过程跟踪、仓库之间合理分配库存等；客户的细分、客户特点分析；订单快速响应、订单跟踪等。但是ERP系统作为一个管理软件，对于上述细化的要求很难满足。因此ERP系统更多的意义上是为企业的信息系统搭建一个框架和规范，其他专业系统通过接口实现与ERP系统的集成，从而实现电商管理的目标。 那么如何实现线上商城与线下ERP，线下ERP与财务系统的对接，实现数据实时同步呢？这是现在电商平台面临的问题。下面将主要介绍电子商务行业是如何解决这一问题的。 2 项目介绍 案例中的企业主营图书，音乐，手机通讯，数码，大家电，小家电等，是集生鲜蔬菜，服饰家居，图书音像一体综合性网络购物中心。线上线下相互结合，全方位满足了消费者不同购物体验的需求，是对零售业商业模式的颠覆和管理体系的重塑，重新定义了零售业全新的模式和标准。

As a way to learn RabbitMQ and python I'm working on a project that allows me to distribute h264 encodes between a number of computers. The basics are done, I have a daemon that runs on Linux or Mac that attaches to queue, accepts jobs and encodes them using HandBrakeCLI and acks the message once the encode is complete. I've also built a simple tool to push items into the queue. Now I want to expand the capabilities of the tool that pushes items into the queue so that I can view what is in the queue. I'm aware of the ability to see how many items are in the queue, but I want to be able to get

For me JMS and ESB seem to be very related things and I'm trying to understand how exactly they are related. I've seen a sentence that JMS can be used as a transport for ESB - then what else except the transport should be present in such an ESB? Is JMS a simple ESB or if not, then what it lacks from the real ESB? JMS offers a set of APIs for messaging: put a message on a queue, someone else, sometime later, perhaps geographically far away takes the message off the queue and processes it. We have decoupled in time and location of the message provider and consumer. Even if the message consumer

Howto reference WSDL files from the registry when defining a new proxy service? I am using WSO2 ESB. Q1: Can I use the localEntry element to define the WSDL in my proxy service? For example: localEntry key="my_wsdl" src="file:/wsdl/MyServiceSOAP.wsdl" Provided that I have previously used Management Console > Add Collection > create "wsdl", and Add Resource > MyServiceSOAP.wsdl. I have a problem with the "src" value, both "/wsdl/MyServiceSOAP.wsdl" and "wsdl/MyServiceSOAP.wsdl" do not work. I follow the documentation but they do not show howto upload WSDLs into the registry. Q2: What if

I'm struggling with a pros and cons list regarding NServiceBus and MassTransit. Now I know there is already a thread in here, but it doesn't really answer my questions. Here is what I've read so far: NServiceBus, yes it's licensed and it doesn't come for free. MassTransit, yes it's open source, but the documentation seems to lack somewhat. NServiceBus is older, and has more references. It's hard to find stuff about MassTransit, but I'm open-minded. However I have to deliver a solid solution, and so I have to ask. So please, someone with experience with both frameworks. Why should I choose

Hey, If we have Apache Camel why to use other solutions like Apache ServiceMix and Mule? Is there something Apache Camel can't do comparing to these products? When to use Mule/ServiceMix and when to use Camel? Apache Camel is a library that implements enterprise integration patterns (EIP). While it can use Spring as its IOC framework, it is not even dependent upon Spring, so it is completely platform independent. It is "just" a library. So you can run it any JVM environment, e.g. simple jvm, servlet, ejb, osgi. It does not bring with any of the benefits (or the overhead) of a container such

Thanks for attention i used spring integration in my project, i want to retrieve many input file from multiple ftp server with different address as bellow image: how to create dynamically inbound-adapter in my project to polling and retrieve files from servers? Gary Russell See the dynamic-ftp sample . While it only covers the outbound side, there are links in the README to discussions about what needs to be done on the inbound side (put each adapter in a child context that send messages to a channel in the main context). Also see my answer to a similar question for multiple IMAP mail adapters
