火狐浏览器下载的是页面

//下载的方法如下
public void sendToClient() throws Exception {
File file = null;
try {
FacesContext facesContext = FacesContext.getCurrentInstance();
ServletContext servletContext = (ServletContext) facesContext
.getExternalContext().getContext();
String filePath = (String) servletContext.getRealPath("/")
+ "dataCollector/WorkDBDownload";

        String fileName = "WorkDB.Assets";
        file = new File(filePath + "/download" + "_" + currentOrgan.getId()
                + "/" + fileName);
        HttpServletResponse response = (HttpServletResponse) facesContext
                .getExternalContext().getResponse();
        response.setContentType("application/x-msdownload");
        String header = RequestParam.getRequest().getHeader("User-Agent");
        if (header.indexOf("MSIE") > 0) {
            response.setHeader("Content-disposition",
                    "attachment;filename=" + fileName);
        } else {
            StringBuffer contentDisposition = new StringBuffer();
            response.setHeader(
                    "Content-disposition",
                    new String(contentDisposition.toString().getBytes(
                            System.getProperty("file.encoding")),
                            "iso8859_1"));
        }
        FileInputStream fin = new FileInputStream(file);
        byte[] b = new byte[(int) file.length()];
        fin.read(b);
        ServletOutputStream sos = response.getOutputStream();
        sos.write(b);
        sos.flush();
        sos.close();
        // 需要呼叫Complete
        facesContext.responseComplete();
        fin.close();
    } catch (Exception e) {
        throw new Exception("下载导出文件错误！", e);
    }

}

我的是jsf，需要下载WorkDB.Asset这个文件，这个文件要用sqlite数据库打开的那种， 名字和后缀固定死的，用ie好好的，用火狐下载就是download。jsf，但是修改成这个后缀名还能用里面的数据？求解，谢谢了！付数据库工具和下载错误的那个文件

if (header.indexOf("MSIE") > 0) {
response.setHeader("Content-disposition",
"attachment;filename=" + fileName);
} else {
原因========
貌似都要设置
response.setHeader("Content-disposition",
"attachment;filename=" + fileName);

这是我之前写的 除了360浏览器好像有问题 其他浏览器均没问题 你试着改改吧

对，对于下载类型应该设置为：
response.setContentType("application/x-download");

我给你回复了啊
esponse.setHeader("Content-Disposition", "attachment;filename="
+ new String((fileName).getBytes("gb2312"), "ISO8859-1"));
