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"><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><DL><DT><B>See Also: </B><DD><A HREF="../../javax/servlet/ServletOutputStream.html"><CODE>ServletOutputStream</CODE></A></DL><HR><P><!-- ======== INNER CLASS SUMMARY ======== --><!-- =========== FIELD SUMMARY =========== --><!-- ======== CONSTRUCTOR SUMMARY ======== --><!-- ========== METHOD SUMMARY =========== --><A NAME="method_summary"><!-- --></A><TABLE BORDER="1" CELLPADDING="3" CELLSPACING="0" WIDTH="100%"><TR BGCOLOR="#CCCCFF" CLASS="TableHeadingColor"><TD COLSPAN=2><FONT SIZE="+2"><B>Method Summary</B></FONT></TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE> void</CODE></FONT></TD><TD><CODE><B><A HREF="../../javax/servlet/ServletResponse.html#flushBuffer()">flushBuffer</A></B>()</CODE><BR> Forces any content in the buffer to be written to the client.</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE> int</CODE></FONT></TD><TD><CODE><B><A HREF="../../javax/servlet/ServletResponse.html#getBufferSize()">getBufferSize</A></B>()</CODE><BR> Returns the actual buffer size used for the response.</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE> java.lang.String</CODE></FONT></TD><TD><CODE><B><A HREF="../../javax/servlet/ServletResponse.html#getCharacterEncoding()">getCharacterEncoding</A></B>()</CODE><BR> Returns the name of the character encoding (MIME charset) used for the body sent in this response.</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE> java.lang.String</CODE></FONT></TD><TD><CODE><B><A HREF="../../javax/servlet/ServletResponse.html#getContentType()">getContentType</A></B>()</CODE><BR> Returns the content type used for the MIME body sent in this response.</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE> java.util.Locale</CODE></FONT></TD><TD><CODE><B><A HREF="../../javax/servlet/ServletResponse.html#getLocale()">getLocale</A></B>()</CODE><BR> Returns the locale specified for this response using the <A HREF="../../javax/servlet/ServletResponse.html#setLocale(java.util.Locale)"><CODE>setLocale(java.util.Locale)</CODE></A> method.</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE> <A HREF="../../javax/servlet/ServletOutputStream.html">ServletOutputStream</A></CODE></FONT></TD><TD><CODE><B><A HREF="../../javax/servlet/ServletResponse.html#getOutputStream()">getOutputStream</A></B>()</CODE><BR> Returns a <A HREF="../../javax/servlet/ServletOutputStream.html"><CODE>ServletOutputStream</CODE></A> suitable for writing binary data in the response.</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE> java.io.PrintWriter</CODE></FONT></TD><TD><CODE><B><A HREF="../../javax/servlet/ServletResponse.html#getWriter()">getWriter</A></B>()</CODE><BR> Returns a <code>PrintWriter</code> object that can send character text to the client.</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE> boolean</CODE></FONT></TD><TD><CODE><B><A HREF="../../javax/servlet/ServletResponse.html#isCommitted()">isCommitted</A></B>()</CODE><BR> Returns a boolean indicating if the response has been committed.</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE> void</CODE></FONT></TD><TD><CODE><B><A HREF="../../javax/servlet/ServletResponse.html#reset()">reset</A></B>()</CODE><BR> Clears any data that exists in the buffer as well as the status code and headers.</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE> void</CODE></FONT></TD><TD><CODE><B><A HREF="../../javax/servlet/ServletResponse.html#resetBuffer()">resetBuffer</A></B>()</CODE><BR> Clears the content of the underlying buffer in the response without clearing headers or status code.</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE> void</CODE></FONT></TD><TD><CODE><B><A HREF="../../javax/servlet/ServletResponse.html#setBufferSize(int)">setBufferSize</A></B>(int size)</CODE><BR> Sets the preferred buffer size for the body of the response.</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE> void</CODE></FONT></TD><TD><CODE><B><A HREF="../../javax/servlet/ServletResponse.html#setCharacterEncoding(java.lang.String)">setCharacterEncoding</A></B>(java.lang.String charset)</CODE><BR>?? 快捷鍵說明
