<DT>public interface <B>ServletResponse</B></DL>
<P>
Defines an object to assist a servlet in sending a response to the client.
The servlet container creates a <code>ServletResponse</code> object and
passes it as an argument to the servlet's <code>service</code> method.
<p>To send binary data in a MIME body response, use
the <A HREF="../../javax/servlet/ServletOutputStream.html" title="class in javax.servlet"><CODE>ServletOutputStream</CODE></A> returned by <A HREF="../../javax/servlet/ServletResponse.html#getOutputStream()"><CODE>getOutputStream()</CODE></A>.
To send character data, use the <code>PrintWriter</code> object
returned by <A HREF="../../javax/servlet/ServletResponse.html#getWriter()"><CODE>getWriter()</CODE></A>. To mix binary and text data,
for example, to create a multipart response, use a
<code>ServletOutputStream</code> and manage the character sections
manually.
<p>The charset for the MIME body response can be specified
explicitly using the <A HREF="../../javax/servlet/ServletResponse.html#setCharacterEncoding(java.lang.String)"><CODE>setCharacterEncoding(java.lang.String)</CODE></A> and
<A HREF="../../javax/servlet/ServletResponse.html#setContentType(java.lang.String)"><CODE>setContentType(java.lang.String)</CODE></A> methods, or implicitly
using the <A HREF="../../javax/servlet/ServletResponse.html#setLocale(java.util.Locale)"><CODE>setLocale(java.util.Locale)</CODE></A> method.
Explicit specifications take precedence over
implicit specifications. If no charset is specified, ISO-8859-1 will be
used. The <code>setCharacterEncoding</code>,
<code>setContentType</code>, or <code>setLocale</code> method must
be called before <code>getWriter</code> and before committing
the response for the character encoding to be used.
<p>See the Internet RFCs such as
<a href="http://www.ietf.org/rfc/rfc2045.txt">
RFC 2045</a> for more information on MIME. Protocols such as SMTP
and HTTP define profiles of MIME, and those standards
are still evolving.
