我正在通过点击链接下载文件。我使用jdk1.7, cxf-2.7.5，并在客户端和服务器中启用了MTOM。对于UI，我使用struts1.2。我得到了下面的异常

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。只有对于较大的文件，我才得到null。该异常只发生在大文件中。我已经注释了LoggingINInterceptor和LoggingOutInterceptor。
我使用localtransport作为发布服务。请告诉我MTOM功能是否适用于localtransport ?如果它是适用的，为什么代码不工作?
检查您的导入。可能您正在导入com.sun.xml.internal.ws.developer.JAXWSProperties，而不是com.sun.xml.ws.developer.JAXWSProperties。或你可以尝试禁用HttpTransportPipe。转储到服务器
