从flex webservice生成的xml无效

我试图让flex与spring ws-webservice进行通信。但是flex生成一个soap请求,它既没有被payloadvalidatinginterceptor验证,也没有被soapui验证。这个问题似乎与XML名称空间的使用有关。

未验证的消息如下:

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" >
  <soapenv:Header/>
  <soapenv:Body>
    <getAccountDataRequest xmlns="http://test.com/services/Account">
      <accountNumber>537048.001</accountNumber>
    </getAccountDataRequest>
  </soapenv:Body>
</soapenv:Envelope>

以下两种变体都经过验证:

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" >
  <soapenv:Header/>
  <soapenv:Body>
    <ac:getAccountDataRequest xmlns:ac="http://test.com/services/Account">
      <accountNumber>537048.001</accountNumber>
    </ac:getAccountDataRequest>
  </soapenv:Body>
</soapenv:Envelope>

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/"
                  xmlns:ac="http://test.com/services/Account">
  <soapenv:Header/>
  <soapenv:Body>
    <ac:getAccountDataRequest>
      <accountNumber>537048.001</accountNumber>
    </ac:getAccountDataRequest>
  </soapenv:Body>
</soapenv:Envelope>

根据我对所读文献的理解,第一个版本也应该是有效的。

是不是Spring和Soapui在他们接受的方面太挑剔了?或者flex生成的xml无效?

谢谢你的帮助!
