Sending complex object via JMS in Java
Is it possible to send complex messages via JMS? I can send TextMessages, Messages etc .. but when I try to send my custom object type MyObject
trough send()
method of MessageProducer
I get compile error.
Then I tried to cast it, I get cast exception like MyObject cannot be cast to开发者_运维技巧 javax.jms.Message
Here is a code I tried :
MessageProducer messageProducer = session.createProducer(destination);
messageProducer.send((Message)getMyObject()); //where getMyObject method retrieves mapped myObject type
anyone got any advice? thank you
As long as your object is Serializable
, you can use an ObjectMessage
MessageProducer producer = session.createProducer( destination );
ObjectMessage message = session.createObjectMessage( getMyObject() );
producer.send( message );
You have one of two problems:
- MyObject does not implement javax.jms.Message
- getMyObject does not return a MyObject (assuming that it does implement Message)
