3.在WebSphere应用服务器中配置数据源在应用服务器中配置数据源
首先要确认所用的数据库是支持JDBC2.0的，并确保我们的操作系统环境设置为支持 JDBC 2.0。这是使用 WebSphere应用服务器创建的数据源所必需的。这一点在使用UDB DB2 7.2的时候尤其要注意。要确定使用哪个数据源：数据源V4.0还是 V5.0 数据源。数据源V4.0是使用 WebSphere 旧连接管理器体系结构的 phere 4.x 中的数据源，所有的 EJB1.x 模块都必须使用此数据源。 WebSphere应用服务器5.x提供对 V4.0 的 JDBC 连接管理器模型的支持，使得 J2EE 1.2 应用程序能够不经改变地运行。WAS 5.x 也支持J2EE 1.3的应用， J2EE 1.3 应用程序内的 EJB 2.0 模块， WEB 2.3模块需要使用 V5.0的JDBC 连接管理器。创建 JDBC 提供程序。JDBC提供程序指的是JDBC驱动程序的类型及其相应的驱动程序实现JAVA包。创建数据源。数据源是在提供特定 JDBC 驱动程序实现类的 JDBC 提供程序下创建的。绑定资源引用。J2EE 1.3标准推荐使用数据源的引用而不是直接使用数据源的名称。测试连接。WebSphere应用服务器5.0.x及5.1提供了数据源配置页面上提供了测试数据源连接的测试按钮。

使用JMS和WebSphereESB构建强大而可靠的SOA.

Java™ Message Service (JMS) 对J2EE™ 平台上的可靠消息传递进行了标准化。

最近发布的IBM® WebSphere® Enterprise Service Bus (ESB) 产品提供了一些重要的功能，这些功能位于任何基于面向服务的体系结构(SOA) 的环境核心位置。

本系列共三篇文章，描述如何将JMS 和WebSphere ESB 结合使用，以形成强大而可靠的SOA。

使用JMS 和WebSphere ESB 构建强大而可靠的SOA——第2 部分使用JMS 和WebSphere ESB 构建强大而可靠的SOA——第3 部分引言面向服务的体系结构(SOA) 永远不能建立在真空中。

在任何实际的环境中，都必须考虑现有的IT 环境，功能（和数据）的提供并不能简单地通过提供一组新服务来实现。

因此，构建S OA 的一个关键方面就是将现有应用程序分解为更小的块（即“服务”），这些块通过标准协议进行通信，并具有定义良好的接口。

这样做的优势在于，此类环境更为灵活，整个系统的各个部分之间并不存在紧密耦合。

松散耦合且具有平台独立性的服务的概念通过使用企业服务总线（Enterprise Service Bus，ESB）得到了进一步发展。

其中，ESB 充当使用不同数据和消息格式、网络协议和编程语言的服务之间的“粘合剂”。

ESB 充当服务使用者和服务提供者之间的中间层，允许部署中介，以执行各种操作，如向交互应用服务质量或执行所需的数据转换。

在本系列的文章中，我们将了解一个ESB 充当此类中间层的具体例子。

我们将利用IBM W ebSphere Enterprise Service Bus (WebSphere ESB) V6.0.1 产品来链接服务使用者和服务提供者，同时使用JMS 作为消息传递机制。

在第一篇文章中，我们将简单了解一下W ebSphere ESB 产品及其工具环境，即WebSphere Integration Developer V6.0.1。

WebSphere环境下的SSO

WebSphere环境下的SSO(Single sign-on：单点登录、全网漫游)实现之: -- SSO实现技术准备简介：本文中作者给大家详细地解释了SSO的基本原理以及WebSphere中的SSO实现机制。

标记本文！发布日期： 2003 年8 月01 日级别：初级SSO（Single Sign-On）直译为一次登录，SSO的机制就是在企业网络用户访问企业网站时作一次身份认证，随后就可以对所有被授权的网络资源进行无缝的访问，SSO可以提高网络用户的工作效率，降低了系统出错的几率，但是比较难于实现。

本文中作者给大家详细地解释了SSO的基本原理以及WebSphere中的SSO实现机制。

1 SSO简介SSO（Single Sign-On）直译为一次登录，WebSphere中更加形象的解释是"单点登录、全网漫游"，意思就是说所有已相同的DNS域名结尾的机器，可以共享用户的认证信息，比如：, 就可以经过配置后实现SSO.SSO的机制就是在企业网络用户访问企业网站时作一次身份认证，随后就可以对所有被授权的网络资源进行无缝的访问，而不需要多次输入自己的认证信息。

SSO可以提高网络用户的工作效率，降低网络操作的费用，并提高网络的安全性，而且降低了系统出错的几率，但是比较难于实现。

1.1 以前的用户登录模式为了实现企业的信息化、电子商务和其他需求，越来越多的信息系统在网上出现，这些企业的网络用户和系统管理员不得不面对这个现实：1. 用户需要使用其中的任何一个企业应用的时候都需要做一次身份认证，而且每一次认证使用的认证信息（用户民和密码）不能保证一致；2. 系统管理员需要对每一个系统设置一种单独的安全策略,而且需要为每个系统中的用户单独授权以保证他们不能访问他们没有被授权访问的网络资源。

图1 ：目前使用的多点登录的示意图1.2 SSO登录模式以前使用的登录系统中，需要给每一台机器上的系统，甚至是每台机器上的每个应用准备一套用户管理系统和系统用户授权策略，考虑到互操作的可操作性和安全问题，SSO将一个企业内部所有域中的用户登录和用户帐号管理集中到一起，SSO的好处显而易见：1. 减少用户在不同系统中登录耗费的时间，减少用户登录出错的可能性2. 实现安全的同时避免了处理和保存多套系统用户的认证信息3. 减少了系统管理员增加、删除用户和修改用户权限的时间4. 增加了安全性：系统管理员有了更好的方法管理用户，包括可以通过直接禁止和删除用户来取消该用户对所有系统资源的访问权限图2：SSO的认证示意图回页首2 SSO理论基础SSO并不是J2EE中的标准实现，而是各家中间件提供商在提供J2EE应用服务器集群时提供的一种认证信息共享的机制，所以各家厂商提供的实现方式不一样，IBM的WebSphere是通过cookies记录认证信息，BEA的WebLogic通过session共享技术实现认证信息的共享，国内深圳金蝶的apusic采用的和BEA的技术基本一致。

IBM WebSphere SOA Governance 商业服务管理说明书

Adapt and respond dynamically to change with SOA-based business processesHighlights■Helps IT enable business peo-ple to respond quickly to press-ing business problems whilesaving IT effort and money■Supports rapid innovation and the ﬂexibility to change acrossmultiple business processesand disparate IT systems■Enables the creation, manage-ment and governance ofBusiness Services ■Allows business service policiesto direct the action of a busi-ness process■Provides a single Web-basedgraphical user interface forbusiness users to interact withbusiness processes and busi-ness process managementapplication content acrossIBM WebSphere products■Speeds time to market withprebuilt industry assets thatleverage years of investmentsin systems and applicationsChange is accelerating … will youkeep up?Rapidly changing economic conditions,aggressive and low-cost global com-petitors, more complex regulatoryrequirements and industry consolidationare driving transformative change at apace faster than most organizationshave ever encountered before. Themandates to businesses today:respond rapidly to competition, capital-ize on new market opportunities andreduce exposure to risk.A 2008 IBM survey of more than1,000 CEOs revealed that 87 percent ofthem believe fundamental change isrequired within the next two years todrive innovation in their businesses.What’s more, the survey said thatbecoming a globally integrated enter-prise is inevitable, yet the gap betweenthe expected change and the ability tohandle it has tripled to 22percent.IBM WebSphere Business Services Fabric for Multiplatforms and z/OSIBM customers have made it clear why managing change is top of mind. Here are some common concerns:●Corporate acquisitions cause overlaps and duplications in systems.●Existing systems make it difficult to document activities for compliance regulations.●Packaged application implementations have driven the change request backlog up rather than down.Gain competitive advantage and foster innovation with agilityWhether your company offers a ﬁrst-rate customer advantage program, a hyper-efficient patient billing application or the industry’s fastest online banking service, you should realize that your key differentiators and competitive advan-tages are contained in your business processes and not limited to discreet product or service offerings. Companies today are raising the bar with competi-tive advantages delivered through their business processes. If you haven’t already, you should start thinking of your business processes as key strate-gic assets and competitive weapons.Nearly every CEO believes his or her business model will need to change. However, closing the gap between change and the organization’s ability to handle it is made difficult by rigid busi-ness processes, traditional tightly cou-pled and segregated capabilities, lackof business and IT alignment, and inad-equate skills and tools.To close this gap, you need to considera new approach. Business processmanagement (BPM) powered by theIBM Smart service oriented architecture(IBM Smart SOA™) improves how youdesign, manage and optimize yourbusiness processes by helping you toefficiently build solutions, reuse yourexisting assets and be ﬂexible in dealingwith change.Combining BPM with the Smart SOAapproach is becoming an imperative forcompanies that want to maintain lead-ership in their industry. Used together,BPM and the Smart SOA approachoffer high levels of agility, ﬂexibility andprocess optimization without “reinvent-ing the wheel” each time a processchange occurs. IBM WebSphere®“W e have seen morechange in the last10 years than in theprevious 90.”—Ad F. Scheepbouwer, CEO,KPN T elecom*Business Services Fabric combinesBPM and the Smart SOA approach,enabling business analysts to rapidlycreate new enterprise processes andmake concurrent changes to processeswith governance—but with minimalimpact to IT and without scrappingexisting IT assets.WebSphere Business Services Fabricuses shareable, reusable BusinessServices driven by Business ServicePolicies that enable you to deﬁne, man-age and implement changes to busi-ness processes through conﬁguration.Simpler, more accurate, and far lesscostly than hard-coding ﬁne-grainedrules and custom code, working withPolicies enables you to react quickly tochanging business needs, enabling anincreasing return on investment (ROI).Business Service Policies also enableimproved modeling, visibility and moni-toring within the larger businessprocess.WebSphere Business Services Fabricstores and acts upon formerly inﬂexible,individual process attributes, such asroles, channels and rules, in a central-ized, easily updatable meta data storeand runtime environment. This enablesenterprise-wide Business Policychanges to be simultaneously sharedacross all applicable processes. ThisDynamic Service Selection capabilitygives you the ﬂexibility to customize service delivery through multiple com-munication channels, including the Internet, business-to-business (B2B) and interactive voice response (IVR) systems.Increase ROI for existing IT assets WebSphere Business Services Fabric helps incrementally improve your com-pany’s ROI by using the IT assets you already have and bringing them into a dynamic environment in which you can continuously make sound business improvements. Reusing or sharing Business Services further escalates your ROI. A change that previously might have taken months to complete can be reduced to hours, so your com-pany, your customers and your compe-tition experience immediate impact.WebSphere Business Services Fabric provides a standards-based offering to help IT manage the life cycle of Business Services and make their assembly and deployment simple, fast and business-driven. Our life-cycle management capabilities include the ability to source, model, assemble, deploy, manage and govern localand remote Business Services from service discovery to retirement.WebSphere Business Services Fabricprovides integrated runtime, design-time and management capabilities,including:●A highly scalable runtime engine fordeﬁning and enforcing Business ServicePolicies, enabling Dynamic BusinessService assembly and behavior adapta-tion based on Content, Context andContract.●Controls and automates entitlement ofBusiness Services for subscribers,enabling creation, control and manage-ment of service packages to subscribers.Can integrate with leading security andidentity management products.●Visibility and monitoring of businessprocesses and applications, plus analy-sis of events and exceptions.●End-to-end governance of BusinessServices through design, run time,deployment and management.●Storage and management of BusinessServices, Business Service Policies, andBusiness Service entitlements.To better support business users,WebSphere Business Services Fabricincorporates IBM Business Space, acommon, graphical user interface thatenables business analysts to create andchange their own and corporate-wideprocesses by managing BusinessServices, Business Service Policies andbusiness vocabulary.

SOA应用——统一认证
在石油企业内部,有许多不同的网站,进入每个网站,都需要身份验证,不仅浪费时间而且容易遗忘代码 ,另外,网站维护人员对各种服务需要建立相应的用户认证与信息管理系统,分布于个服务器中的用户数据不仅浪费维护人员的时间,而且过于分散的用户数据不利于统计和管理,用户的需求和管理要求促使用户趋于统一,产生了统一者认证,
统一认证的实现是基于SOA的架构,
SOA应用——统一认证
从中可以看出使用SOA的优点：将身份验证这一功能模块发布成一种服务,其他的软件可以通过UUDI查找该服务,然后将该服务与服务的实现进行绑定,
