SAAJ呼吁通过肥皂发送附件的例外

Question

我在通过SOAP调用Web服务时会得到以下例外：

Mar 02, 2017 6:24:39 PM com.sun.xml.internal.messaging.saaj.soap.MessageImpl writeTo
SEVERE: SAAJ0540: Error during saving a multipart message
com.sun.xml.internal.messaging.saaj.SOAPExceptionImpl: Error during saving a multipart message
    at com.sun.xml.internal.messaging.saaj.soap.MessageImpl.writeTo(MessageImpl.java:1337)

    at com.sun.xml.internal.messaging.saaj.soap.MessageImpl.writeTo(MessageImpl.java:1328)
    ... 2 more

原因：

下面是我的代码段。我正在使用Datatype -Text/Plain发送文本文件。任何人都可以帮助我理解这一点。我正在使用Java 1.7

        SOAPConnection connection =factory.createConnection();  
        msgFactory = MessageFactory.newInstance();
        SOAPMessage reqMessage = msgFactory.createMessage();
        AttachmentPart attachment =  reqMessage.createAttachmentPart();
        attachment.setContent(fileStream,dataType);
        reqMessage.addAttachmentPart(attachment);
        StringBuffer sbuf=new StringBuffer();
        sbuf.append("n").append(reqMessage.toString()); 
        System.out.println(sbuf);
        ByteArrayOutputStream baos = new ByteArrayOutputStream();
        reqMessage.writeTo(baos);                     
        sbuf.append(baos.toString());         
        endpoint = new URL(endPointAddress);
        responseMsg= (SOAPMessage)connection.call(reqMessage, endpoint);

根据例外，它期望字符串为附件内容。

尝试与此类似。

 AttachmentPart ap1 = m.createAttachmentPart();
 ap1.setContent(contentString, "text/plain");
 m.addAttachmentPart(ap1);
