Examples with MessageFormatException javax.jms.MessageFormatException used on opensource projects

Example 1 with MessageFormatException

use of javax.jms.MessageFormatException in project qpid by apache.

the class AMQPMessage method getList.

/**
     * JMS QMF returns amqp/list types as a BytesMessage this method decodes that into a java.util.List
     * <p>
     * Taken from Gordon Sim's initial JMS QMF Example using the BBDecoder
     * <p>
     * Trivia: This block of code from Gordon Sim is the seed that spawned the whole of this Java QMF2 API
     * implementation - cheers Gordon.
     *
     * @param message amqp/list encoded JMS Message
     * @return a java.util.List decoded from Message

             * out of this by iterating through the getMapNames() Enumeration and copying the Objects into the List.
             * This amount of copying doesn't feel healthy and we can't even work out the capacity for the List
             * a priori, but I'm not sure of a better way at present. I can't say I much like how amqp/list or indeed
             * amqp/map are currently encoded. I'd *much* prefer to see them exposed as JMS ObjectMessage.
