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.<P><P><DL><DT><B>Version:</B></DT> <DD>$Version$</DD><DT><B>Author:</B></DT> <DD>Various</DD><DT><B>See
