文件下载
Java code:
采用RequestDispatcher的方式进行
1、web.xml文件中增加
<mime-mapping>
<extension>doc</extension>
<mime-type>application/vnd.ms-word</mime-type>
</mime-mapping>

2、程序如下：
<%@page language=\"java\" import=\"java.net.*\" pageEncoding=\"gb2312\"%>
<%

response.setContentType(\"application/x-download\"); //设置为下载application/x-download
String filenamedownload = \"/系统解决方案.doc\"; //即将下载的文件的相对路径
String filenamedisplay = \"系统解决方案.doc\"; //下载文件时显示的文件保存名称
filenamedisplay = URLEncoder.encode(filenamedisplay,\"UTF-8\");
response.addHeader(\"Content-Disposition\",\"attachment;filename=\" + filenamedisplay);

try
{
RequestDispatcher dispatcher = application.getRequestDispatcher(filenamedownload);
if(dispatcher != null)
{
dispatcher.forward(request,response);
}
response.flushBuffer();
}
catch(Exception e)
{
e.printStackTrace();
}
finally
{
