Java Servlet Programming

Name

ServletOutputStream

Synopsis

Class Name: javax.servlet.ServletOutputStream

Superclass: java.io.OutputStream

Immediate Subclasses: None

Interfaces Implemented: None

Availability: Servlet API 1.0 and later

Description

Provides an output stream for sending binary data back to a client. A servlet obtains a ServletOutputStream object from the getOutputStream() method of ServletResponse. Although it includes a range of print() and println() methods for sending text or HTML, the ServletOutputStream has been superseded by PrintWriter. It should be used only for sending binary data or with early servlet implementations built on the Servlet API 1.0.

If you subclass ServletOutputStream, you must provide an implementation of the write(int) method.
