Question

我正在迁移使用Maven构建和部署的应用程序。它部署在WebSphere 7上。我已经设法使这个应用程序的一部分（HTML UI等）正常工作，但Web服务出现问题。

当我尝试访问Web服务的URL（例如localhost:9000/MyApplication/MyWebServiceProject/MyService）时，我希望看到一个页面上写着“Hello，这是一个Web服务！”。

相反，我看到了这个例外：

[4/1/13 11:49:37:484 EDT] 0000001d WASAxis2Servl E   The following exception was encountered while attempting to load the ConfigurationContext for the servlet:  com.ibm.ws.websvcs.exception.ConfigurationException: Could not retrieve server module metadata in Axis servlet for module: MyWebServiceProject

我猜测通过Maven部署Web服务需要一些特定于IBM的配置，但我不确定它是什么。

来自POM的EAR项目的相关部分：

当我使用RAD（v8.5）部署到WAS时，这不是问题 - 它只是在我尝试使用Maven构建和部署应用程序之后才开始。有谁知道如何解决这个错误？

事实证明，我必须使用与此处描述的相同的解决方案：

Deployed webservice schema does not match what's in workspace

出于某种原因，当在Maven-build项目中未提供WSDL和模式文件时，WebSphere无法从代码生成WSDL。我报告的错误消息类似于我在运行测试时看到的错误消息，包括EJB项目中的WSDL和模式。
