<pre>public interface <span class="typeNameLabel">ServletResponse</span></pre>
<div class="block">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.</div>

so. In the case of HTTP, the character encoding is communicated as part

the character encoding cannot be communicated via HTTP headers if the

encode text written via the servlet response's writer.</div>
