org.opensaml.xml.security.SecurityException - thrown if the decoded message does not meet the required security constraints

logDecodedMessage

protected void logDecodedMessage(MessageContext messageContext)

Log the decoded message to the protocol message logger.

Parameters:

messageContext - the message context to process
