急！关于下载文件问题！不知道怎么会事情！

[epson1980]

我用这段代码下载个包文件，一切正常，但最后关闭流的时候出现了问题。
<%

// 得到文件名字和路径
String filename = "ftp_with_source_200f_src.rar";
String filepath = "D:\\";

// 设置响应头和下载保存的文件名
response.setContentType("APPLICATION/OCTET-STREAM");
response.setHeader("Content-Disposition",
"attachment; filename=\"" + filename + "\"");

// 打开指定文件的流信息
java.io.FileInputStream fileInputStream =
new java.io.FileInputStream(filepath + filename);
try
{
// 写出流信息
int i;
while ((i=fileInputStream.read()) != -1) {
out.write(i);
}
}
catch(Exception e)
{
e.printStackTrace();
}
finally
{
fileInputStream.close();
out.close();
}
%>

在finally中我关闭流就有异常出现。
如果我删除掉，就没问题了。
我现在怕如果不关闭流的话，资源会不会无法释放，导致中间件崩溃。
异常如下：
java.io.IOException: Stream closed

解决了，原来不该把out.close();关闭。
