Java Datahandler cxf的OutofMemoryException

我正在通过单击链接下载文件。我在客户端和服务器中使用jdk1.7、cxf-2.7.5和启用的MTOM。对于UI，我使用struts1.2。 我得到了下面的例外

[default-workqueue-8] ERROR consoleErrorLog - Exception in thread "default-workqueue-8" 
[default-workqueue-8] ERROR consoleErrorLog - java.lang.OutOfMemoryError: Java heap space

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。我只为更大的文件设置null。 只有大型文件才会出现此异常。 我已经注释掉了LogginInterceptor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，为什么代码不工作？

检查您的导入。可能是您正在导入com.sun.xml.internal.ws.developer.JAXWSProperties，而不是com.sun.xml.ws.developer.JAXWSProperties。 或

您可以尝试在服务器中禁用HttpTransportPipe.dump。

您提到的两个导入都是相同的。请告诉我实际的导入，并告诉我如何在java代码中禁用HttpTransportPipe.dump。
