Returns the name of the character encoding used in the body of this request. This method returns null if the request does not specify a character encoding.

java.io.BufferedReader getReader()
                                 throws java.io.IOException

Retrieves the body of the HTTP request from the client to the portal as character data using a BufferedReader. The reader translates the character data according to the character encoding used on the body. Either this method or getInputStream() may be called to read the body, not both.

For HTTP POST data of type application/x-www-form-urlencoded this method throws an IllegalStateException as this data has been already processed by the portal/portlet-container and is available as request parameters.

Returns:

a BufferedReader containing the body of the request

Throws:

java.io.UnsupportedEncodingException - if the character set encoding used is not supported and the text cannot be decoded

java.lang.IllegalStateException - if getInputStream() method has been called on this request, it is a HTTP POST data of type application/x-www-form-urlencoded.

java.io.IOException - if an input or output exception occurred
