Question

我通过点击链接下载文件。我在客户端和服务器上使用jdk1.7，cxf-2.7.5并启用了MTOM。对于UI我使用struts1.2。我得到了以下异常

[default-workqueue-8] ERROR consoleErrorLog - Exception in thread "default-workqueue-8"

Serverside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取null。仅对大文件发生异常。我已经注释掉了LoggingINInterceptor和LoggingOutInterceptor。

我使用localtransport进行发布服务。请告诉我MTOM功能是否适用于localtransport？如果适用，为什么代码不起作用？

检查你的imports.May你要导入com.sun.xml.internal.ws.developer.JAXWSProperties而不是com.sun.xml.ws.developer.JAXWSProperties。要么您可以尝试在服务器中禁用HttpTransportPipe.dump。

使用Datahandler cxf的OutofMemoryException
