java – JAX-WS出错由于异常导致无法创建SOAP消息：XML reader错

错误是：

Couldn’t create SOAP message due to exception: XML reader error:
com.ctc.wstx.exc.WstxUnexpectedCharException: Unexpected character ‘[‘
(code 91) in prolog; expected ‘<‘ at [row,col {unknown-source}]: [1,1]

我打电话的功能是：

private static ContractTermsDownloadReply contractTermsDownloadOperation(
        ContractTermsDownloadRequest body) {
    ContractTermsDownload service = null;
    try {
        URI uri = new URI("https://companyname.com/ContractTermsDownload");
        service = new ContractTermsDownload(uri.toURL());
    } catch (Exception ex) {
        Logger.getLogger(JavaApplication1.class.getName()).log(
                Level.SEVERE,null,ex);
    }

    ariba.sourcing.vrealm_1461.ContractTermsDownloadPortType port = service
            .getContractTermsDownloadPortType();
    BindingProvider prov = (BindingProvider) port;
    prov.getRequestContext().put("authorization","Basic User2011:Password2011");

    try {
        ContractTermsDownloadReply reply = port
                .contractTermsDownloadOperation(body);
        return reply;
    } catch (Exception exc) {
        System.out.println(exc.getMessage());
    }
    return null;
}
