SmartUpload下载成功但tomcat报错

t150ckh 2011-02-28 10:16:10 


<%@ page language="java" pageEncoding="UTF-8"

	contentType="text/html;charset=UTF-8" import="com.jspsmart.upload.*"%>

<% 

// 新建一个SmartUpload对象 

SmartUpload su = new SmartUpload(); 

// 初始化 

su.initialize(pageContext); 

// 设定contentDisposition为null以禁止浏览器自动打开文件， 

//保证点击链接后是下载文件。若不设定，则下载的文件扩展名为 

//doc时，浏览器将自动用word打开它。扩展名为pdf时， 

//浏览器将用acrobat打开。 

su.setContentDisposition(null); 

// 下载文件 

su.downloadFile("/document/"+(String)request.getAttribute("fileName")); 

out.clear();

out=pageContext.pushBody();

%>



这是我用的下载jsp，用的是SmartUpload这个包做下载，有一个情况会出现这个问题就是在点击下载时（如果装有迅雷或其它下载工具会自动启用）如果关闭下载工具想用浏览器下载就会报如下的错误，现在求一个解决方案，有什么好的下载方式可以避免这个问题的发生。

我当时做的也是这样，之后将迅雷浏览器设置为不是默认下载工具，然后再下载就是浏览器下载了，不过在浏览器下载时点击取消，tomcat也会报上面错误，原因是在浏览器下载界面弹出时，文件流已经打开，当单击取消时，没有相应的措施关闭文件流，所以回报IOException

用流的性能肯定好嘛，组件的性能肯定是大大降低了呀！

建议用流来做。你就是下载电影都行。我这里有个以前用Swing加流写的一个类似迅雷的源代码，需要的话加我QQ传给你136893103

也想过用流的形式来做，性能上不知道与组件相比会有什么区别。

下载你可以自己写一段代码呀，弹出IE的下载对话框。
把迅雷的监控浏览器去掉，否则是不会弹出来的！

smartUpload? N年前的组件了吧，记得当时用的时候还改过它的bug，现在应该早就没有更新了。

要上传用apache的common.io和common.net包，很稳定，足够用了
