getPrintWriter
Description copied from interface:ResponseReturns a PrintWriter object to which output may be sent. Invoking flush() on the writer will commit the output.- Specified by:
getPrintWriterin interfaceResponse- Parameters:
contentType- the MIME content type for the output, typically "text/html"- Throws:
IOException
-
getOutputStream
Description copied from interface:ResponseReturns an OutputStream to which byte-oriented output may be sent. Invoking flush() on the stream will commit the output.- Specified by:
getOutputStreamin interfaceResponse- Parameters:
contentType- the MIME content type for the output, often "application/octet-stream" or "text/plain" or one of several others- Throws:
IOException
-
sendRedirect
Description copied from interface:ResponseSends a redirect to the client.- Specified by:
sendRedirectin interfaceResponse- Parameters:
URL- full or partial (relative) URL to send to the client- Throws:
IOException- See Also:
-
sendRedirect
Description copied from interface:ResponseSends a redirect to a link.- Specified by:
sendRedirectin interfaceResponse- Parameters:
link- link to redirect to.- Throws:
IOException
-
setStatus
Description copied from interface:ResponseSets 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 applicaion, thesendErrormethod should be used instead. -
sendError
Description copied from interface:ResponseSends an error response to the client using the specified status. The server defaults to creating the response to look like an HTML-formatted server error page containing the specified message, setting the content type to "text/html", leaving cookies and other headers unmodified. If an error-page declaration has been made for the web application corresponding to the status code passed in, it will be served back in preference to the suggested msg parameter. 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:
sendErrorin interfaceResponse- Parameters:
sc- the error status codemessage- the descriptive message- Throws:
IOException- If an input or output exception occurs
-
setContentLength
Description copied from interface:ResponseSets the length of the content body in the response; this method sets the HTTP Content-Length header.- Specified by:
setContentLengthin interfaceResponse- Parameters:
length- the length of the content
-
setDateHeader
Description copied from interface:ResponseSets 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.- Specified by:
setDateHeaderin interfaceResponse- Parameters:
name- the name of the header to setdate- the assigned date value
-
setHeader
Description copied from interface:ResponseSets a response header with the given name and value. If the header had already been set, the new value overwrites the previous one. -

name- the name of the header to setvalue- the assigned integer value
-
encodeURL
Description copied from interface:ResponseEncodes the URL, ensuring that a session id is included (if a session exists, and as necessary depending on the client browser's use of cookies). -
encodeRedirectURL
Description copied from interface:ResponseEncodes the URL for use as a redirect, ensuring that a session id is included (if a session exists, and as necessary depending on the client browser's use of cookies).- Specified by:
encodeRedirectURLin interfaceResponse- Returns:
- the same URL or a different one with additional information to track the user session
-
isCommitted
Description copied from interface:ResponseReturns true if the response has already been sent, either as a redirect or as a stream of content.- Specified by:
