BufferedInputStream bis = null;
BufferedOutputStream bos = null;

try{

if (!dir.exists()) {
dir.mkdirs();
}

bis = new BufferedInputStream(new FileInputStream(upFile));
bos = new BufferedOutputStream(new FileOutputStream(new File(dir,upFileFileName)));
byte[] buf = new byte[(int)upFile.length()];
int len = 0;
while(((len=bis.read(buf))!=-1)){
bos.write(buf, 0, len);
}
}catch(Exception e){
e.printStackTrace();
}finally{
try{
if(bos!=null){

null 怎么set呢？
JS判断下嘛~

Answer 3

action="uploadimage.html"
