wso2: ws-discovery集成

Question

WSO2 WS-发现集成

我们正在尝试将WS-Discovery与Carbon products、服务治理注册表和Tomcat集成在一起，通过运行在Tomcat上的WSO2配置Apache CXF Web服务堆栈，向WSO2 Greg上的发现代理(本地主机:9443/ WSO2 /DiscoveryProxy)发送问候消息。

因此，我们将cxf-services-ws-discovery-service.jar和cxf-services-ws-discovery-api.jar添加到Tomcat的类路径中。此外，我们将spring bus属性org.apache.cxf.service.ws-discovery.address设置为WSO2 Greg上的WS-Discovery代理的URL地址，以便在托管模式下运行WS-Discovery。通过运行Tomcat和WSO2 Greg，在wso2Carbon.log (WSO2 Greg)中记录了以下错误消息...

我们花了几个小时的时间来解决这个问题，我们阅读了WSO2产品文档，并搜索了几个论坛、博客等。不幸的是，我们找不到解决方案。

备注: WS-Discovery与的集成，而不是WSO2，工作得很好。但是，当使用WSO2 ESB作为发现客户机从WSO2 Greg发现服务时，在创建代理之后，从WSO2 ESB上发现的服务创建代理服务的向导缺少publishWSDL xml标记。此标签必须手动添加。有没有办法在不额外编辑的情况下完成这项工作？？

如有任何帮助，我们将不胜感激。

提前感谢

我们截获了通过Tomcat和WSO2应用服务器发送给WSO2 GReg的问候请求。为此，我们使用了soapUI模拟服务。soap信封的消息请求如下所示...

Tomcat：

WSO2应用程序服务器：

     <wsd:MetadataVersion>1</wsd:MetadataVersion>
  </wsd:Hello>
  </soapenv:Body>
  </soapenv:Envelope>

比较这两个消息请求，我们注意到有一些标签丢失了，如serviceName，wsdlURI，以及在我们看来最重要的是XAddrs。通过手动将XAddrs添加到soapUI请求，我们能够在WSO2 GReg上注册cxf服务。也许你可以给我们一个建议，如何通过spring配置cxf或者注释我们的web服务实现。

谢谢again..this帮了我们很大的忙！
