A quick read of the docs for Interface ServletRequest reveal a
snippet in the description of function getParameter :
You should only use
this method when you are sure the parameter has only one value. If the parameter
might have more than one value, use
getParameterValues(java.lang.String).
getParameterValues
public java.lang.String[] getParameterValues(java.lang.String name)
- Returns an array of
Stringobjects containing all of the values the given request parameter has, ornullif the parameter does not exist.If the parameter has a single value, the array has a length of 1.
- Parameters:
name- aStringcontaining the name of the parameter whose value is requested- Returns:
- an array of
Stringobjects containing the parameter's values - See Also:
getParameter(java.lang.String)

I only get
one, paraname=1, actually I checked 4 boxes, in terms of posted
inputstream,
I should get a array of value, it should be paraname=1,2,4,5.
that is why I
have to use HttpUtil, but now it is not working, so where is
wrong? maybe I
should use servlet instead of jsp, than inputstream will not
be
corrupted.
