我有一个Vanguard Web服务，可以使用自定义Java类调用（使用基本身份验证）。 Java wsimport工具用于生成Java代理存根，并且所有这些都可以完美运行。

Java代码（以下所有类均由wsimport生成，并提供url +身份验证信息）：

Authenticator.setDefault(new SimpleAuth(username,pass)); MyWSObject obj = new MyWSObject(url); -> triggers the exception ServicePortType port = obj.getServicePort(); OutputType result = port.MyWSMethod(params); OutputData data = result.getOutputData(); 当我从matlab运行完全相同的java函数（包含上面的代码）时，webservice调用失败，并出现模糊错误：

??? Java exception occurred: com.sun.xml.internal.ws.streaming.XMLStreamReaderException: XML reader error: com.ctc.wstx.exc.WstxUnexpectedCharException: Unexpected character '"' (code 34) in DOCTYPE declaration; expected a space between public and system identifiers at [row,col,system-id]: [1,63,""] at com.sun.xml.internal.ws.streaming.XMLStreamReaderUtil.wrapException(XMLStreamReaderUtil.java:256) at com.sun.xml.internal.ws.streaming.XMLStreamReaderUtil.next(XMLStreamReaderUtil.java:84) at com.sun.xml.internal.ws.streaming.XMLStreamReaderUtil.nextContent(XMLStreamReaderUtil.java:99) at com.sun.xml.internal.ws.streaming.XMLStreamReaderUtil.nextElementContent(XMLStreamReaderUtil.java:89) at com.sun.xml.internal.ws.wsdl.parser.RuntimeWSDLParser.hasWSDLDefinitions(RuntimeWSDLParser.java:209) at com.sun.xml.internal.ws.wsdl.parser.RuntimeWSDLParser.parse(RuntimeWSDLParser.java:119) at com.sun.xml.internal.ws.client.WSServiceDelegate.parseWSDL(WSServiceDelegate.java:254) at com.sun.xml.internal.ws.client.WSServiceDelegate.(WSServiceDelegate.java:217) at com.sun.xml.internal.ws.client.WSServiceDelegate.(WSServiceDelegate.java:165) at com.sun.xml.internal.ws.spi.ProviderImpl.createServiceDelegate(ProviderImpl.java:93) at javax.xml.ws.Service.(Service.java:56) at edu.soton.decode.activities.vanguardws.MyWSObject.(MyWSObject.java:42) at edu.soton.decode.activities.VanguardActivity.execute(VanguardActivity.java:80) 如果在两种情况下都使用wireshark监视请求/响应，则会看到：

==直接调用Java函数==

以下所有调用/响应都是由wsimport生成的JAX-WS代码自动发生的。我的代码只是在生成的服务代理上调用webservice方法，没有什么花哨的地方。

==与从Matlab内部调用的Java函数完全相同==

我已经设置了MATLAB_JAVA环境变量，以便在两种情况下都使用相同的JVM（Sun 1.6）。我还注意到，Matlab在发送请求时不尊重http.agent属性。

回答：

事实证明，该问题似乎只发生在非Linux平台上的64位版本的Matlab上。如果我安装32位版本的Matlab，效果很好。我将这个问题标记为已回答，因为这似乎是Matlab的问题，Mathworks正在调查该问题（线程ID：1-DUMQQZ]）。
