调用java web服务时SOAP响应中出错

我有一个Java web服务，它返回存储在Alfresco CMS中的文档列表

这个web服务正常运行，当我调用它时，响应正常。但有时情况并非如此，SOAP响应中会出现以下错误：

2014-10-24 12:58:17,047 ERROR [com.company.ws.Exceptions.HrwsException] : WSDoAllSender: cannot get SOAP envlope from messageorg.xml.sax.SAXException: Fatal Error: URI=null Line=1: Attribute "actor" bound to namespace "http://schemas.xmlsoap.org/soap/envelope/" was already specified for element "ns7:QueryHeader".

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:sch="http://<hostname>/webServices/schema">
  <soapenv:Header/>
     <soapenv:Body>
     <sch:listDocumentsRequest username="*****" password="*****">
     <sch:tipo>F</sch:tipo>
     <sch:cod>1</sch:cod>
     <!--Optional:-->
     <sch:abono>0</sch:abono>
     <!--Optional:-->
     <sch:codDivision>01</sch:codDivision>
  </sch:listDocumentsRequestt>

有什么想法吗？发生了什么事？ 谢谢

更新：

我附上了wsdl：

您可以共享您的WSDL文件吗？这将有助于识别问题您能显示定义了ns7:QueryHeader的XSD文件吗？我用wsdl文件更新了这个案例
