Failed to build body from content in activeMQ - Spring generic message used

I send a org.springframework.messaging.support.GenericMessage to a queue in ActiveMQ by org.springframework.jms.core.JmsTemplate. in ActiveMQ, I see this message :

Cannot display ObjectMessage body. Reason: Failed to build body from content. 
    Serializable class not available to broker. 
    Reason: java.lang.ClassNotFoundException: org.springframework.messaging.support.GenericMessage

and so I can't read that message in a client. I set trustAllPackages to true in my activeMQConnectionFactory and problem doesn't solve. How to solve it ?

Simply put:

Add the required jar or class files or the serialised messages in the lib folder of activemq and restart activemq.

It worked for me

The JmsTemplate will serialize the entire GenericMessage as a java object, so spring-messaging is needed on the class path of the receiving system as well.

class not available to broker.

It looks like you might be trying to view the message in the admin UI, which doesn't understand spring-messaging classes.

If you want to map the GenericMessage to a JMS Message instead, use the JmsMessagingTemplate instead (one of the send() methods); the broker might be able to display such a message (depending on the payload type).
