If a content type has been specified and a
character encoding has been explicitly or implicitly
specified as described in ServletResponse.getCharacterEncoding(),
the charset parameter is included in the string returned.
If no character encoding has been specified, the
charset parameter is omitted.

javax.servlet.ServletResponseServletResponse.setCharacterEncoding(java.lang.String) or
ServletResponse.setContentType(java.lang.String) methods, or implicitly using the
ServletResponse.setLocale(java.util.Locale) method. Explicit specifications take
precedence over implicit specifications. Calls made
to these methods after getWriter has been
called or after the response has been committed have no
effect on the character encoding. If no character encoding
has been specified, ISO-8859-1 is returned.
See RFC 2047 (http://www.ietf.org/rfc/rfc2047.txt) for more information about character encoding and MIME.
getCharacterEncoding in interface javax.servlet.ServletResponseString specifying the
name of the character encoding, for
example, UTF-8public void setCharacterEncoding(java.lang.String charEncoding)
javax.servlet.ServletResponseServletResponse.setContentType(java.lang.String) or ServletResponse.setLocale(java.util.Locale),
this method overrides it.
Calling ServletResponse.setContentType(java.lang.String) with the String
of text/html and calling
this method with the String of UTF-8
is equivalent with calling
setContentType with the String of
text/html; charset=UTF-8.
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.
Containers must communicate the character encoding used for
the servlet response's writer to the client if the protocol
provides a way for doing so. In the case of HTTP, the character
encoding is communicated as part of the Content-Type
header for text media types. Note that the character encoding
cannot be communicated via HTTP headers if the servlet does not
specify a content type; however, it is still used to encode text
written via the servlet response's writer.

defined by IANA Character Sets
(http://www.iana.org/assignments/character-sets)#setLocale
public javax.servlet.ServletOutputStream getOutputStream()
throws java.io.IOException
javax.servlet.ServletResponseServletOutputStream suitable for writing binary
data in the response. The servlet container does not encode the
binary data.
Calling flush() on the ServletOutputStream commits the response.
Either this method or ServletResponse.getWriter() may
be called to write the body, not both.

java.io.IOException - if an input or output exception occurredServletResponse.getWriter()public java.util.Locale getLocale()
javax.servlet.ServletResponseServletResponse.setLocale(java.util.Locale) method. Calls made to
setLocale after the response is committed
have no effect. If no locale has been specified,
the container's default locale is returned.
getLocale in interface javax.servlet.ServletResponseServletResponse.setLocale(java.util.Locale)
public java.io.PrintWriter getWriter()
throws java.io.IOException
javax.servlet.ServletResponsePrintWriter object that
can send character text to the client.
The PrintWriter uses the character
encoding returned by ServletResponse.getCharacterEncoding().
If the response's character encoding has not been
specified as described in getCharacterEncoding
(i.e., the method just returns the default value
ISO-8859-1), getWriter
updates it to ISO-8859-1.
Calling flush() on the PrintWriter
commits the response.
Either this method or ServletResponse.getOutputStream() may be called
to write the body, not both.

javax.servlet.ServletResponsegetBufferSize.
A larger buffer allows more content to be written before anything is actually sent, thus providing the servlet with more time to set appropriate status codes and headers. A smaller buffer decreases server memory load and allows the client to start receiving data more quickly.
This method must be called before any response body content is
written; if content has been written or the response object has
been committed, this method throws an
IllegalStateException.

javax.servlet.ServletResponsetext/html;charset=UTF-8.
The response's character encoding is only set from the given
content type if this method is called before getWriter
is called.
This method may be called repeatedly to change content type and
character encoding.
This method has no effect if called after the response
has been committed. It does not set the response's character
encoding if it is called after getWriter
has been called or after the response has been committed.
Containers must communicate the content type and the character
encoding used for the servlet response's writer to the client if
the protocol provides a way for doing so. In the case of HTTP,
the Content-Type header is used.

been called yet, and the response hasn't been committed yet.
If the deployment descriptor contains a
locale-encoding-mapping-list element, and that
element provides a mapping for the given locale, that mapping
is used. Otherwise, the mapping from locale to character
encoding is container dependent.
This method may be called repeatedly to change locale and
character encoding. The method has no effect if called after the
response has been committed. It does not set the response's
character encoding if it is called after ServletResponse.setContentType(java.lang.String)
has been called with a charset specification, after
ServletResponse.setCharacterEncoding(java.lang.String) has been called, after
getWriter has been called, or after the response
has been committed.
Containers must communicate the locale and the character encoding
used for the servlet response's writer to the client if the protocol
provides a way for doing so. In the case of HTTP, the locale is
communicated via the Content-Language header,
the character encoding as part of the Content-Type
header for text media types. Note that the character encoding
cannot be communicated via HTTP headers if the servlet does not
specify a content type; however, it is still used to encode text
written via the servlet response's writer.

javax.servlet.http.HttpServletResponsesendRedirect method or, if encoding is not needed,
returns the URL unchanged. The implementation of this method
includes the logic to determine whether the session ID
needs to be encoded in the URL. Because the rules for making
this determination can differ from those used to decide whether to
encode a normal link, this method is separated from the
encodeURL method.
All URLs sent to the HttpServletResponse.sendRedirect
method should be run through this method. Otherwise, URL
rewriting cannot be used with browsers which do not support
cookies.
