Method Detail

getPortletInputStream
java.io.InputStream getPortletInputStream() throws java.io.IOException
Retrieves the body of the HTTP request from client to portal as binary data using anInputStream
. Either this method orgetReader()
may be called to read the body, but 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:
- an input stream containing the body of the request
- Throws:
java.lang.IllegalStateException
- if getReader was already called, or it is a HTTP POST data of type application/x-www-form-urlencodedjava.io.IOException
- if an input or output exception occurred
-
setCharacterEncoding
void setCharacterEncoding(java.lang.String enc) throws java.io.UnsupportedEncodingException
Overrides the name of the character encoding used in the body of this request. This method must be called prior to reading input usinggetReader()
orgetPortletInputStream()
.This method only sets the character set for the Reader that the
getReader()
method returns.- Parameters:
enc
- aString
containing the name of the chararacter encoding.- Throws:
java.io.UnsupportedEncodingException
- if this is not a valid encodingjava.lang.IllegalStateException
- if this method is called after reading request parameters or reading input usinggetReader()
-
getReader
java.io.BufferedReader getReader() throws java.io.UnsupportedEncodingException, java.io.IOException
Retrieves the body of the HTTP request from the client to the portal as character data using aBufferedReader
. The reader translates the character data according to the character encoding used on the body. Either this method orgetPortletInputStream()
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 decodedjava.lang.IllegalStateException
- ifgetPortletInputStream()
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- See Also:
getPortletInputStream()
-
getCharacterEncoding

Returns the name of the character encoding used in the body of this request. This method returnsnull
if the request does not specify a character encoding.- Returns:
- a

if the request does not specify a character encoding.
-
