      public void replaceCookie(HttpCookie cookie)
      Deprecated.
      Replace (or add) a cookie. Using name, path and domain, look for a matching set-cookie header and replace it.
      Parameters:
      cookie - The cookie to add/replace

    • addCookie

      public void addCookie(Cookie cookie)
      Deprecated.
      Description copied from interface: HttpServletResponse
      Adds the specified cookie to the response. This method can be called multiple times to set more than one cookie.
      Specified by:
      addCookie in interface HttpServletResponse
      Parameters:
      cookie - the Cookie to return to the client

    • containsHeader

      public boolean containsHeader(String name)
      Deprecated.
      Description copied from interface: HttpServletResponse
      Returns a boolean indicating whether the named response header has already been set.
      Specified by:
      containsHeader in interface HttpServletResponse
      Parameters:
      name - the header name
      Returns:
      true if the named response header has already been set; false otherwise

    • encodeURL

      public String encodeURL(String url)
      Deprecated.
      Description copied from interface: HttpServletResponse
      Encodes the specified URL by including the session ID in it, 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. For example, if the browser supports cookies, or session tracking is turned off, URL encoding is unnecessary.

      For robust session tracking, all URLs emitted by a servlet should be run through this method. Otherwise, URL rewriting cannot be used with browsers which do not support cookies.

      Specified by:
      encodeURL in interface HttpServletResponse
      Parameters:
      url - the url to be encoded.
      Returns:
      the encoded URL if encoding is needed; the unchanged URL otherwise.

    • encodeRedirectURL

      public String encodeRedirectURL(String url)
      Deprecated.
      Description copied from interface: HttpServletResponse
      Encodes the specified URL for use in the sendRedirect 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.

      Specified by:
      encodeRedirectURL in interface HttpServletResponse
      Parameters:
      url - the url to be encoded.
      Returns:
      the encoded URL if encoding is needed; the unchanged URL otherwise.
      See Also:

    • encodeUrl

      Deprecated.
      Specified by:
      encodeUrl in interface HttpServletResponse
      Parameters:
      url - the url to be encoded.
      Returns:
      the encoded URL if encoding is needed; the unchanged URL otherwise.

    • encodeRedirectUrl

      @Deprecated public String encodeRedirectUrl(String url)
      Deprecated.
      Specified by:
      encodeRedirectUrl in interface HttpServletResponse
      Parameters:

      public void sendError(int sc) throws IOException
      Deprecated.
      Description copied from interface: HttpServletResponse
      Sends an error response to the client using the specified status code and clears the buffer. This is equivalent to calling HttpServletResponse.sendError(int, String) with the same status code and null for the message.
      Specified by:
      sendError in interface HttpServletResponse
      Parameters:
      sc - the error status code
      Throws:
      IOException - If an input or output exception occurs

    • sendError

      public void sendError(int code, String message) throws IOException
      Deprecated.
      Send an error response.

      In addition to the servlet standard handling, this method supports some additional codes:

      102
      Send a partial PROCESSING response and allow additional responses
      -1
      Abort the HttpChannel and close the connection/stream
      Specified by:
      sendError in interface HttpServletResponse
      Parameters:
      code - The error code
      message - The message
      Throws:
      IOException - If an IO problem occurred sending the error response.

    • sendProcessing

      public void sendProcessing() throws IOException
      Deprecated.
      Sends a 102-Processing response. If the connection is an HTTP connection, the version is 1.1 and the request has a Expect header starting with 102, then a 102 response is sent. This indicates that the request still be processed and real response can still be sent. This method is called by sendError if it is passed 102.
      Throws:
      IOException - if unable to send the 102 response
      See Also:

    • sendRedirect

      public void sendRedirect(int code, String location) throws IOException

      Throws:
      IOException - if unable to send the redirect

    • sendRedirect

      public void sendRedirect(String location, boolean consumeAll) throws IOException
      Deprecated.
      Sends a response with a HTTP version appropriate 30x redirection.
      Parameters:
      location - the location to send in Location headers
      consumeAll - if True, consume any HTTP/1 request input before doing the redirection. If the input cannot be consumed without blocking, then add a `Connection: close` header to the response.

      IOException - if unable to send the redirect

    • sendRedirect

      public void sendRedirect(int code, String location, boolean consumeAll) throws IOException
      Deprecated.
      Sends a response with a given redirection code.
      Parameters:
      code - the redirect status code
      location - the location to send in Location headers
      consumeAll - if True, consume any HTTP/1 request input before doing the redirection. If the input cannot be consumed without blocking, then add a `Connection: close` header to the response.
      Throws:
      IOException - if unable to send the redirect

    • sendRedirect

      public void sendRedirect(String location) throws IOException
      Deprecated.
      Description copied from interface: HttpServletResponse
      Sends a temporary redirect response to the client using the specified redirect location URL. This method can accept relative URLs; the servlet container must convert the relative URL to an absolute URL before sending the response to the client. If the location is relative without a leading '/' the container interprets it as relative to the current request URI. If the location is relative with a leading '/' the container interprets it as relative to the servlet container root.

      If the response has already been committed, this method throws an IllegalStateException. After using this method, the response should be considered to be committed and should not be written to.

      Specified by:
      sendRedirect in interface HttpServletResponse
      Parameters:
      location - the redirect location URL
      Throws:
      IOException - If an input or output exception occurs

      Deprecated.
      Description copied from interface: HttpServletResponse
      Sets a response header with the given name and date-value. The date is specified in terms of milliseconds since the epoch. If the header had already been set, the new value overwrites the previous one. The containsHeader method can be used to test for the presence of a header before setting its value.
      Specified by:

      public String getHeader(String name)
      Deprecated.
      Description copied from interface: HttpServletResponse
      Return the value for the specified header, or null if this header has not been set. If more than one value was added for this name, only the first is returned; use HttpServletResponse.getHeaders(String) to retrieve all of them.
      Specified by:
      getHeader in interface HttpServletResponse
      Parameters:
      name - Header name to look up

    • setStatus

      public void setStatus(int sc)
      Deprecated.
      Description copied from interface: HttpServletResponse
      Sets the status code for this response. This method is used to set the return status code when there is no error (for example, for the status codes SC_OK or SC_MOVED_TEMPORARILY). If there is an error, and the caller wishes to invoke an error-page defined in the web application, the sendError method should be used instead.

      The container clears the buffer and sets the Location header, preserving cookies and other headers.

      Specified by:
      setStatus in interface HttpServletResponse
      Parameters:
      sc - the status code
      See Also:

    • setStatus

      @Deprecated public void setStatus(int sc, String sm)
      Deprecated.
      Description copied from interface: HttpServletResponse
      Sets the status code and message for this response.
      Specified by:
      setStatus in interface HttpServletResponse
      Parameters:
      sc - the status code
      sm - the status message

    • setStatusWithReason

      public void setStatusWithReason(int sc, String sm)
      Deprecated.

    • getCharacterEncoding

      public String getCharacterEncoding()
      Deprecated.
      Description copied from interface: ServletResponse
      Returns the name of the character encoding (MIME charset) used for the body sent in this response. The character encoding may have been specified explicitly using the ServletResponse.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.

      Specified by:
      getCharacterEncoding in interface ServletResponse
      Returns:
      a String specifying the name of the character encoding, for example, UTF-8

    • getContentType

      public String getContentType()
      Deprecated.
      Description copied from interface: ServletResponse
      Returns the content type used for the MIME body sent in this response. The content type proper must have been specified using ServletResponse.setContentType(java.lang.String) before the response is committed. If no content type has been specified, this method returns null. 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.
      Specified by:
      getContentType in interface ServletResponse
      Returns:
      a String specifying the content type, for example, text/html; charset=UTF-8, or null

    • getOutputStream

      public ServletOutputStream getOutputStream() throws IOException
      Deprecated.
      Description copied from interface: ServletResponse
      Returns a ServletOutputStream 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.

      Specified by:
      getOutputStream in interface ServletResponse
      Returns:
      a ServletOutputStream for writing binary data
      Throws:
      IOException - if an input or output exception occurred
      See Also:

    • isWriting

      public boolean isWriting()
      Deprecated.

    • isWritingOrStreaming

      public boolean isWritingOrStreaming()
      Deprecated.

    • getWriter

      public PrintWriter getWriter() throws IOException
      Deprecated.
      Description copied from interface: ServletResponse
      Returns a PrintWriter 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.

      Specified by:
      getWriter in interface ServletResponse
      Returns:
      a PrintWriter object that can return character data to the client
      Throws:
      IOException - if an input or output exception occurred
      See Also:

    • setContentLength

      public void setContentLength(int len)
      Deprecated.
      Description copied from interface: ServletResponse
      Sets the length of the content body in the response In HTTP servlets, this method sets the HTTP Content-Length header.
      Specified by:
      setContentLength in interface ServletResponse
      Parameters:
      len - an integer specifying the length of the content being returned to the client; sets the Content-Length header

    • getContentLength

      public long getContentLength()
      Deprecated.

    • isAllContentWritten

      public boolean isAllContentWritten(long written)

      Deprecated.
      Throws:
      IOException

    • completeOutput

      @Deprecated public void completeOutput() throws IOException
      Deprecated.
      Use closeOutput()
      close the output
      Throws:
      IOException

    • completeOutput

      public void completeOutput(Callback callback)
      Deprecated.

    • getLongContentLength

      public long getLongContentLength()
      Deprecated.

    • setLongContentLength

      public void setLongContentLength(long len)
      Deprecated.

    • setContentLengthLong

      public void setContentLengthLong(long length)
      Deprecated.
      Description copied from interface: ServletResponse
      Sets the length of the content body in the response In HTTP servlets, this method sets the HTTP Content-Length header.
      Specified by:
      setContentLengthLong in interface ServletResponse
      Parameters:
      length - an integer specifying the length of the content being returned to the client; sets the Content-Length header

    • setCharacterEncoding

      public void setCharacterEncoding(String encoding)
      Deprecated.
      Description copied from interface: ServletResponse
      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 ServletResponse.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.

      Specified by:
      setCharacterEncoding in interface ServletResponse
      Parameters:
      encoding - a String specifying only the character set defined by IANA Character Sets (http://www.iana.org/assignments/character-sets)
      See Also:

    • setContentType

      public void setContentType(String contentType)
      Deprecated.
      Description copied from interface: ServletResponse
      Sets the content type of the response being sent to the client, if the response has not been committed yet. The given content type may include a character encoding specification, for example, text/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.

      Specified by:
      setContentType in interface ServletResponse
      Parameters:
      contentType - a String specifying the MIME type of the content
      See Also:

    • setBufferSize

      public void setBufferSize(int size)
      Deprecated.
      Description copied from interface: ServletResponse
      Sets the preferred buffer size for the body of the response. The servlet container will use a buffer at least as large as the size requested. The actual buffer size used can be found using getBufferSize.

      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.

      Specified by:
      setBufferSize in interface ServletResponse
      Parameters:
      size - the preferred buffer size
      See Also:

    • getBufferSize

      public int getBufferSize()
      Deprecated.
      Description copied from interface: ServletResponse
      Returns the actual buffer size used for the response. If no buffering is used, this method returns 0.
      Specified by:
      getBufferSize in interface ServletResponse
      Returns:
      the actual buffer size used
      See Also:

    • flushBuffer

      public void flushBuffer() throws IOException
      Deprecated.
      Description copied from interface: ServletResponse
      Forces any content in the buffer to be written to the client. A call to this method automatically commits the response, meaning the status code and headers will be written.
      Specified by:
      flushBuffer in interface ServletResponse
      Throws:
      IOException - if an I/O occurs during the flushing of the response
      See Also:

    • reset

      public void reset()
      Deprecated.
      Description copied from interface: ServletResponse

      Get the MetaData.Response committed for this response. This may differ from the meta data in this response for exceptional responses (eg 4xx and 5xx responses generated by the container) and the committedMetaData should be used for logging purposes.
      Returns:
      The committed MetaData or a newResponseMetaData() if not yet committed.

    • isCommitted

      public boolean isCommitted()
      Deprecated.
      Description copied from interface: ServletResponse
      Returns a boolean indicating if the response has been committed. A committed response has already had its status code and headers written.
      Specified by:
      isCommitted in interface ServletResponse
      Returns:
      a boolean indicating if the response has been committed

    • setLocale

      public void setLocale(Locale locale)
      Deprecated.
      Description copied from interface: ServletResponse
      Sets the locale of the response, if the response has not been committed yet. It also sets the response's character encoding appropriately for the locale, if the character encoding has not been explicitly set using ServletResponse.setContentType(java.lang.String) or ServletResponse.setCharacterEncoding(java.lang.String), getWriter hasn't 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.
