getPrintWriter
public java.io.PrintWriter getPrintWriter(java.lang.String contentType) throws java.io.IOException

java.io.IOException
-
getOutputStream
public java.io.OutputStream getOutputStream(java.lang.String contentType) throws java.io.IOException
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:
java.io.IOException
-
sendRedirect
public void sendRedirect(java.lang.String URL) throws java.io.IOException
Description copied from interface:ResponseSends a redirect to the client.- Specified by:

URL- full or partial (relative) URL to send to the client- Throws:
java.io.IOException- See Also:
Response.encodeRedirectURL(String)
-
sendRedirect
public void sendRedirect(Link link) throws java.io.IOException
Description copied from interface:ResponseSends a redirect to a link.- Specified by:

setStatus
public void setStatus(int sc)
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
public void sendError(int sc, java.lang.String message) throws java.io.IOException
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.
-
