public abstract class ServletOutputStream

extends java.io.OutputStream

Provides an output stream for sending binary data to the client. A 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.
