doPost question

[Heather]

Can you help me with this sample?

void doPost(HttpServletRequest arg0, httpServletResponse arg1) throws ServletException, IOException {
InputStream in=arg0.getInputStream();
byte[] b=new byte[50];
in.read(b);
for(byte i : b){
System.out.println(i) ;
}
}

I post a parameter such as "for=12345" through a form,but above code can not read byte from stream. I change the code as

InputStreamReader isr = new InputStreamReader (in);
BufferedReader br = new BufferedReader (isr);
System.out.println(br.readLine()) ;

it prints "for=12345"
why??

You shoulde get it by the following code:

 arg0.getParameter("for")
