<A NAME="setLocale(java.util.Locale)"><!-- --></A><H3>
setLocale</H3>
<PRE>
void <B>setLocale</B>(java.util.Locale&nbsp;loc)</PRE>
<DL>
<DD>Sets the locale of the response, setting the headers 
 (including the Content-Type's charset) as appropriate. 
 This method should be called before a call to getWriter(). 
 By default, the response locale is the default locale provided
 by the portlet container.

<DT><B>Parameters:</B><DD><CODE>loc</CODE> - the new locale of the response</DL>

<A NAME="setCharacterEncoding(java.lang.String)"><!-- --></A><H3>
setCharacterEncoding</H3>
<PRE>
void <B>setCharacterEncoding</B>(java.lang.String&nbsp;charset)</PRE>
<DL>
<DD>Sets the character encoding (MIME charset) of the response being 
 sent to the client, for example, to UTF-8. If the character encoding 
 has already been set by either the portlet container,
 <code>setContentType(java.lang.String)</code> or 
 <code>setLocale(java.util.Locale)</code>, this method overrides it. Calling 
 <code>setContentType(java.lang.String)</code> with the String  of 
 <code>text/html</code> and calling this method with the String of 
 <code>UTF-8</code> is equivalent with calling <code>setContentType</code> 
 with the String of <code>text/html; charset=UTF-8</code>.
 <p>
 This method can be called repeatedly to change the character encoding. 
 This method has no effect if it is called after getWriter has been called 
 or after the response has been committed.

<DD>Creates a portlet URL targeting the portlet. If no portlet mode, window
 state or security modifier is set in the PortletURL the current values
 are preserved. If a request is triggered by the PortletURL, it results in
 a render request.

 The returned URL can be further extended by adding portlet-specific
 parameters and portlet modes and window states.
 <p>
 The created URL will per default not contain any parameters of the
 current render request.

<DL>
<DD><B>Description copied from interface: <CODE><A HREF="../../javax/portlet/MimeResponse.html#createResourceURL()">MimeResponse</A></CODE></B></DD>
<DD>Creates a portlet URL targeting the portlet. If no security modifier is
 set in the PortletURL the current values are preserved. The current
 render parameters, portlet mode and window state are preserved.
 <p>
 If a request is triggered by the PortletURL, it results in a serve
 resource request of the <code>ResourceServingPortlet</code> interface.

 The returned URL can be further extended by adding portlet-specific
 parameters .
 <p>
 The created URL will per default contain the current 
 cacheability setting of the parent resource. 
 If no parent resource is available, <code>PAGE</code> is the default.
