Class ServletOutputStream

java.lang.Object

java.io.OutputStream

javax.servlet.ServletOutputStream

All Implemented Interfaces:

Closeable, Flushable, AutoCloseable

public abstract class ServletOutputStream
extends OutputStream

Used to write output from a Servlet to the client. Servlet engines should provide a subclass of ServletOutputStream that implements OutputStream.write(int).

Note that I (MJW) do not understand how the print methods work when the stream uses something else then a simple ASCII character encoding. It seems saver to use ServletResponse.getWriter() for all output that is not binary.

Since:

Servlet API 1.0

Version:

Servlet API 2.2
