public abstract class ServletOutputStream
extends java.io.OutputStream
ServletOutputStream object is normally retrieved via the
ServletResponse.getOutputStream() method.
This is an abstract class that the servlet container implements. Subclasses
of this class must implement the java.io.OutputStream.write(int)
method.
