  1. J2EE——第10章Java API for XML Registries

  2. JAXR概述 • XML Registries用于构建、部署、发现Web服务(ebXML,UDDI) • JAXR体系结构

  3. 实现JAXR客户端 • 查找连接工厂 import javax.xml.registry.*; import javax.naming.*; ... Context context = new InitialContext(); ConnectionFactory connFactory = (ConnectionFactory) context.lookup("java:comp/env/eis/JAXR"); • 创建连接工厂 ConnectionFactory connFactory = ConnectionFactory.newInstance();

  4. 创建连接 Properties props = new Properties(); props.setProperty("javax.xml.registry.queryManagerURL", "http://uddi.ibm.com/testregistry/inquiryapi"); props.setProperty("javax.xml.registry.lifeCycleManagerURL", "https://uddi.ibm.com/testregistry/publishapi"); connFactory.setProperties(props); Connection connection = connFactory.createConnection();

  5. 设置连接属性 • javax.xml.registry.queryManagerURL • javax.xml.registry.lifeCycleManagerURL • javax.xml.registry.semanticEquivalences • javax.xml.registry.security.authenticationMethod • javax.xml.registry.uddi.maxRows • javax.xml.registry.postalAddressScheme • com.sun.xml.registry.http.proxyHost (https) • com.sun.xml.registry.http.proxyPort (https) • com.sun.xml.registry.http.proxyUserName • com.sun.xml.registry.http.proxyPassword • com.sun.xml.registry.useCache • com.sun.xml.registry.userTaxonomyFilenames

  6. 获取和使用RegistyService对象 RegistryService rs = connection.getRegistryService(); BusinessQueryManager bqm = rs.getBusinessQueryManager(); BusinessLifeCycleManager blcm = rs.getBusinessLifeCycleManager();

  7. 按名称查找组织 Collection findQualifiers = new ArrayList(); findQualifiers.add(FindQualifier.SORT_BY_NAME_DESC); //findQualifiers.add(FindQualifier.CASE_SENSITIVE_MATCH); Collection namePatterns = new ArrayList(); namePatterns.add(qString); //namePatterns.add("%" + qString + "%"); BulkResponse response =bqm.findOrganizations(findQualifiers, namePatterns, null, null, null, null); Collection orgs = response.getCollection();

  8. 按类别查找组织 ClassificationScheme cScheme= bqm.findClassificationSchemeByName(null, "ntis-gov:naics"); Classification classification = blcm.createClassification(cScheme, “Snack and Nonalcoholic Beverage Bars", “722213"); Collection classifications = new ArrayList(); classifications.add(classification); BulkResponse response = bqm.findOrganizations(null, null, classifications, null, null, null); Collection orgs = response.getCollection();

  9. 基于WSDL提供服务的组织 String schemeName = “uddi-org:types"; ClassificationScheme uddiOrgTypes = bqm.findClassificationSchemeByName(null, schemeName); Classification wsdlSpecClassification = blcm.createClassification(uddiOrgTypes, "wsdlSpec", "wsdlSpec"); Collection classifications = new ArrayList(); classifications.add(wsdlSpecClassification); BulkResponse br = bqm.findConcepts(null, null, classifications, null, null);

  10. 搜查概念 Collection specConcepts = br.getCollection(); Iterator iter = specConcepts.iterator(); while (iter.hasNext()) { Concept concept = (Concept) iter.next(); //getKey(concept) String name = getName(concept); //getDescription(concept) Collection links = concept.getExternalLinks(); if (links.size() > 0) { ExternalLink link = (ExternalLink) links.iterator().next(); System.out.println("\tURL of WSDL document: '" + link.getExternalURI() + "'"); } Collection specConcepts1 = new ArrayList(); specConcepts1.add(concept); br = bqm.findOrganizations(null, null, null, specConcepts1, null, null); }

  11. 查找服务和服务绑定 Iterator orgIter = orgs.iterator(); while (orgIter.hasNext()) { Organization org = (Organization) orgIter.next(); Collection services = org.getServices(); Iterator svcIter = services.iterator(); while (svcIter.hasNext()) { Service svc = (Service) svcIter.next(); Collection serviceBindings = svc.getServiceBindings(); Iterator sbIter = serviceBindings.iterator(); while (sbIter.hasNext()) { ServiceBinding sb = (ServiceBinding) sbIter.next(); } } }

  12. 管理注册数据 • 从注册获取授权 • 创建组织 • 添加类别 • 将服务和服务绑定添加到组织 • 发布组织 • 发布规范概念 • 从注册删除数据

  13. 从注册获取授权 String username = "myUserName"; String password = "myPassword"; // Get authorization from the registry PasswordAuthentication passwdAuth = new PasswordAuthentication(username, password.toCharArray()); Set creds = new HashSet(); creds.add(passwdAuth); connection.setCredentials(creds);

  14. 创建组织 InternationalString s = blcm.createInternationalString("The Coffee Break"); Organization org = blcm.createOrganization(s); s = blcm.createInternationalString("Purveyor of " + "the finest coffees. Established 1914"); org.setDescription(s); User primaryContact = blcm.createUser(); PersonName pName = blcm.createPersonName("Jane Doe"); primaryContact.setPersonName(pName); TelephoneNumber tNum = blcm.createTelephoneNumber(); tNum.setNumber("(800) 555-1212"); Collection phoneNums = new ArrayList(); phoneNums.add(tNum); primaryContact.setTelephoneNumbers(phoneNums); org.setPrimaryContact(primaryContact);

  15. 添加类别 ClassificationScheme cScheme= bqm.findClassificationSchemeByName(null, "ntis-gov:naics"); Classification classification = blcm.createClassification(cScheme, “Snack and Nonalcoholic Beverage Bars", “722213"); Collection classifications = new ArrayList(); classifications.add(classification); org.addClassifications(classifications);

  16. 将服务和服务绑定添加到组织 Collection services = new ArrayList(); InternationalString s = blcm.createInternationalString("My Service Name"); Service service = blcm.createService(s); s = blcm.createInternationalString("My Service Description"); service.setDescription(s); Collection serviceBindings = new ArrayList(); ServiceBinding binding = blcm.createServiceBinding(); s = blcm.createInternationalString(“My Service Binding ” +“Description”); binding.setDescription(s); binding.setValidateURI(false); binding.setAccessURI("http://TheCoffeeBreak.com:8080/sb/"); serviceBindings.add(binding); service.addServiceBindings(serviceBindings); services.add(service); org.addServices(services);

  17. 发布组织 Collection orgs = new ArrayList(); orgs.add(org); BulkResponse response = blcm.saveOrganizations(orgs); Collection exceptions = response.getException(); if (exceptions == null) { Collection keys = response.getCollection(); Iterator keyIter = keys.iterator(); if (keyIter.hasNext()) { javax.xml.registry.infomodel.Key orgKey = (javax.xml.registry.infomodel.Key) keyIter.next(); String id = orgKey.getId(); System.out.println("Organization key is " + id); } }

  18. 发布规范概念 InternationalString s = blcm.createInternationalString("HelloConcept"); Concept specConcept = blcm.createConcept(null, s, ""); s = blcm.createInternationalString( "Concept for Hello Service"); specConcept.setDescription(s); s = blcm.createInternationalString("Hello WSDL document"); ExternalLink wsdlLink = blcm.createExternalLink( "http://localhost:8080/hello-jaxrpc/hello?WSDL", s); specConcept.addExternalLink(wsdlLink); ClassificationScheme uddiOrgTypes= bqm.findClassificationSchemeByName(null, “uddi-org:types”); Classification wsdlSpecClassification = blcm.createClassification(uddiOrgTypes, "wsdlSpec", "wsdlSpec"); specConcept.addClassification(wsdlSpecClassification);

  19. 检索概念关键字 Collection concepts = new ArrayList(); concepts.add(specConcept); BulkResponse concResponse = blcm.saveConcepts(concepts); String conceptKeyId = null; Collection concExceptions = concResponse.getExceptions(); javax.xml.registry.infomodel.Key concKey = null; if (concExceptions == null) { Collection keys = concResponse.getCollection(); Iterator keyIter = keys.iterator(); if (keyIter.hasNext()) { concKey = (javax.xml.registry.infomodel.Key) keyIter.next(); conceptKeyId = concKey.getId(); } }

  20. 将概念设置到服务绑定 Concept specConcept = (Concept) bqm.getRegistryObject(conceptKeyId, LifeCycleManager.CONCEPT); SpecificationLink specLink = blcm.createSpecificationLink(); specLink.setSpecificationObject(specConcept); binding.addSpecificationLink(specLink); • 使用名称和类别查找概念 Collection namePatterns = new ArrayList(); namePatterns.add("HelloConcept"); BulkResponse br = bqm.findConcepts(null, namePatterns, classifications, null, null);

  21. 从注册删除数据 String id = key.getId(); Collection keys = new ArrayList(); keys.add(key); BulkResponse response = blcm.deleteOrganizations(keys); Collection exceptions = response.getException(); if (exceptions == null) { Collection retKeys = response.getCollection(); Iterator keyIter = retKeys.iterator(); javax.xml.registry.infomodel.Key orgKey = null; if (keyIter.hasNext()) { orgKey = (javax.xml.registry.infomodel.Key) keyIter.next(); id = orgKey.getId(); System.out.println("Organization key was " + id); } }

  22. 添加用户定义的分类法 ClassificationScheme cScheme = blcm.createClassificationScheme("MyScheme", "A Classification Scheme"); ClassificationScheme uddiOrgTypes = bqm.findClassificationSchemeByName(null, "uddi-org:types"); if (uddiOrgTypes != null) { Classification classification = blcm.createClassification(uddiOrgTypes, "postalAddress", "postalAddress" ); cScheme.addClassification(classification); ExternalLink externalLink =blcm.createExternalLink( "http://www.mycom.com/myscheme.html", "My Scheme"); cScheme.addExternalLink(externalLink); Collection schemes = new ArrayList(); schemes.add(cScheme); BulkResponse br = blcm.saveClassificationSchemes(schemes); }

  23. 得到scheme uuid if (br.getStatus() == JAXRResponse.STATUS_SUCCESS) { System.out.println("Saved ClassificationScheme"); Collection schemeKeys = br.getCollection(); Iterator keysIter = schemeKeys.iterator(); while (keysIter.hasNext()) { javax.xml.registry.infomodel.Key key = (javax.xml.registry.infomodel.Key) keysIter.next(); System.out.println("The postalScheme key is " + key.getId()); System.out.println("Use this key as the scheme" + " uuid in the taxonomy file"); } }

  24. 将分类法添加到JAXR提供者 <JAXRClassificationScheme id="uuid:nnnnnnnn-nnnn-nnnn-nnnn-nnnnnnnnnnnn“ name="MyScheme"> <JAXRConcept id="uuid:C0B9FE13-179F-413D-8A5B-5004DB8E5BB2/11" name="Agriculture, Forestry, Fishing and Hunting" parent="uuid:C0B9FE13-179F-413D-8A5B-5004DB8E5BB2" code="11"></JAXRConcept> props.setProperty("com.sun.xml.registry.userTaxonomyFilenames", "c:\mydir\xxx.xml|c:\mydir\xxx2.xml");

  25. 运行客户端示例 • JAXRQuery.java显示如何为组织搜索注册 • JAXRQueryByNAICSClassification.java显示如何使用通用分类方案搜索注册 • JAXRQueryByWSDLClassification.java显示如何为使用WSDL文档方法进行自我描述的Web服务搜索注册 • JAXRPublish.java显示如何将组织发布到注册 • JAXRDelete.java显示如何从注册删除组织 • JAXRSaveClassificationScheme.java显示如何将分类方案发布到注册 • JAXRPublishPostal.java显示如何从组织检索邮政地址 • JAXRDeleteScheme.java显示如何从注册删除分类方案 • JAXRPublishConcept.java显示如何发布WSDL文档概念

  26. 运行客户端示例 • JAXRPublishHelloOrg.java显示如何发布带有引用WSDL文档的服务绑定的组织 • JAXRDeleteConcept.java显示如何删除概念 • JAXRMyObjects.java列出你在注册中拥有的所有对象 • build.xml • JAXRExamples.properties • postalconcepts.xml

  27. 在J2EE应用程序中使用JAXR客户端 • 编码应用程序客户端MyAppClient.java，它使用JNDI lookup获取一个到PubQuery企业bean的远程home接口的句柄，使用句柄创建bean的实例并调用其executePublish和executeQuery方法 • 编码PubQuery会话bean • 编译源文件 • 导入证书 • 启动Application Server • 创建JAXR资源(通过连接器资源访问JAXR资源适配器) • 创建、打包、部署应用程序 • 运行应用程序客户端
