Spring boot + JMS + IBM MQ

I'm trying to send a message to a IBM MQ queue from my spring boot service. Configuration is as follows:

Application.properties

ibm.mq.queueManager=QM1
ibm.mq.queue=DEV.QUEUE.1
ibm.mq.channel=DEV.APP.RECEIVER
ibm.mq.host=localhost
ibm.mq.port=1414

ConectionFactory Bean

@Bean
        public MQQueueConnectionFactory mqQueueConnectionFactory() {
            MQQueueConnectionFactory mqQueueConnectionFactory = new MQQueueConnectionFactory();
            mqQueueConnectionFactory.setHostName(host);
            try {
                mqQueueConnectionFactory.setTransportType(WMQConstants.ADMIN_QUEUE_DOMAIN);
                mqQueueConnectionFactory.setCCSID(1208);
                mqQueueConnectionFactory.setChannel(channel);
                mqQueueConnectionFactory.setPort(port);
                mqQueueConnectionFactory.setQueueManager(queueManager);
            } catch (Exception e) {
                e.printStackTrace();
            }
            return mqQueueConnectionFactory;
        }

When i try to send a message i get the error:

It appears (as Mark mentioned) you are using the wrong channel type. I quick google tells me that Spanish Receptor translates in English to Receiver. A Receiver type channel is a Message channel and is used for queue manager to queue manager communication.

For MQ Client (ex: spring boot) to queue manager communication you need to connect to a MQI channel, on the queue manager this will have the type server connection.

The IBM MQ v8 Knowledge Center page "IBM MQ Explorer>Configuring IBM MQ using MQ Explorer>Creating and configuring queue managers and objects>Objects in MQ Explorer>Channels" documents this:

Message channel
A message channel is a unidirectional communications link between two queue managers. IBM MQ uses message channels to transfer messages between the queue managers. To send messages in both directions, you must define a channel for each direction.

MQI channel
An MQI channel is bidirectional and connects an application (MQI client) to a queue manager on a server machine. IBM MQ uses MQI channels to transfer MQI calls and responses between MQI clients and queue managers.

IBM documents each type further down the page:

Message channels

Message channel definitions can be one of the following types:

Receiver
A receiver channel is a message channel that the queue manager uses to receive messages from other queue managers. To receive messages using a receiver channel, you must also create, on the other queue manager, a sender or a server channel with the same name as this receiver channel.

MQI channels

MQI channels can be one of the following types:

Server connection
A server connection channel is a bidirectional MQI channel that is used to connect an IBM MQ client to an IBM MQ server. The server connection channel is the server end of the channel.

Client programs connect to SVRCONN channels, not RECEIVERs.
