Axis2 客户端意外的子元素苹果答案

【问题标题】：Axis2 client Unexpected subelement appleAxis2 客户端意外的子元素苹果
【发布时间】：2011-06-20 04:19:14
【问题描述】：

我使用 Axis2 版本 1.5.4、Java 1.6 开发了服务器和客户端应用程序，服务器部署在 tomcat 6 上。服务是使用注释声明的，因此没有 .aar 文件或任何此类文件。 WSDL 是由 Axis2 自动创建的。客户端是使用 WSDL2Java 使用以下命令生成的存根和参数创建的：

%axis2_home%\bin\WSDL2Java -p com.audaxys.leaseclient.servicestub.generic -d adb -Eosv -s -g -u -uw -or -sp -S src/main/java -R src/main/resources --noBuildXML -uri %baseurl%/AppleFinderService.Rpc?wsdl

当客户端应用调用public Apple loadApple(String appType)方法时，服务器响应返回一个Apple类实例，但客户端无法反序列化响应并抛出此异常。

如果你知道如何解决这个问题，可以分享给我吗？任何线索将不胜感激，真的！

【解决方案1】：

您的帖子很难阅读，但我相信问题出在 WSDL 和 XSD 上。您有一个元素、complexType 和消息部分都具有相同的名称“apple”。我会尝试按照约定 here 修改 WSDL：

<element name="Apple" type="tns:AppleType"/>
<complexType name="AppleType">
...
</complexType>

<message name="loadAppleResponse">
  <part name="apple" element="tns:Apple"/>        
</message>

【解决方案2】：

我遇到过类似的问题，我使用 JAX-WS API 注释了 EJB SLSB，并使用 RPC 作为 SOAP Bindind 样式。在 JBoss5.1 中部署 EJB，JBOSSWS 生成 WSDL。

当我通过 Axis1 客户端测试 Web 服务时，它运行良好，但是在使用 Axis2 客户端测试时，请求已发送到服务器，甚至数据库事务也成功。

但是当响应到达客户端时，它说 Unexpected 子元素返回等等。然后我更改了它与 Axis2 一起使用的 SOAP 绑定样式。

 @WebService 
  @SOAPBinding(style=Style.DOCUMENT, parameterStyle = ParameterStyle.WRAPPED)
  public interface BillingAccountManagement_SEI { // TODO}
