我正在通过单击链接下载文件。我正在使用 jdk1.7、cxf-2.7.5 并在客户端和服务器中都启用了 MTOM。对于 UI，我使用的是 struts1.2。我得到了以下异常

服务器端代码：
DataHandler theDataHandler = new DataHandler(new FileDataSource(new File("filename"");
aResponse.setHeader("Pragma", "dummy");
aResponse.setHeader("Cache-Control", "private");
String contentType = "text/plain";
aResponse.setContentType(contentType);
aResponse.setHeader("Content-Disposition",
"attachment; filename=\"" + name + ".txt\"");
if (theDataHandler != null)
{
downloadFile(inputStream from datahandler, response OutputStream());
}
使用 Datahandler 处理下载。我只为较大的文件获得空值。该异常仅发生在大文件中。我已经注释掉了 LoggingINInterceptor 和 LoggingOutInterceptor。
我正在使用 localtransport 进行发布服务。请告诉我 MTOM 功能是否适用于本地传输？如果适用，为什么代码不起作用？
