java.lang.Objectjava.io.InputStream
javax.servlet.ServletInputStream
Provides an input stream for reading binary data from a client
 request, including an efficient 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 client.
 
A ServletInputStream object is normally retrieved via
 the ServletRequest.getInputStream() method.
 
This is an abstract class that a servlet container implements.
 Subclasses of this class
 must implement the java.io.InputStream.read() method.

public int readLine(byte[] b,

                    int len)
             throws java.io.IOException
This method returns -1 if it reaches the end of the input stream before reading the maximum number of bytes.
b - an array of bytes into which data is readoff - an integer specifying the character at which
				this method begins readinglen - an integer specifying the maximum number of
