Okay everybody, say it with me. RTFM!
If you had actually bothered to read a book or check out the javadocs you
would have noticed this:
>From the java docs http://java.sun.com/j2ee/j2sdkee/techdocs/api/index.html
(under javax.servlet.ServletRequest):
getParameter
public java.lang.String getParameter(java.lang.String name)
Returns the value of a request parameter as a String, or null if the
parameter does not exist. Request parameters are extra information sent
with the request. For HTTP servlets, parameters are contained in the query
string or posted form data.
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).
If you use this method with a multivalued parameter, the value
returned is equal to the first value in the array returned by
getParameterValues.
If the parameter data was sent in the request body, such as occurs
with an HTTP POST request, then reading the body directly via
getInputStream() or getReader() can interfere with the execution of this
method.
Parameters:
name - a String specifying the name of the parameter
Returns:
a String representing the single value of the parameter
See Also:
getParameterValues(java.lang.String)
A little research into solving your own damn problem before posting to the
list goes a long way.
