public abstract class ServletInputStream
extends java.io.InputStream
readLine method for reading data one line
at a time. With some protocols, such as HTTP POST and PUT, a
ServletInputStream object can be used to read data sent from the

this class must implement the java.io.InputStream.read() method.
