Hi there,
I am trying to implement jms to my grails application.
I have several JMS consumer in a spring based enviroment listining on an ActiveMQ broker. I wrote a simple test commandline client which creates messages and receives them in an request response manner.
Here is the snippet that sends a MapMessage in Spring JMS way. This works for me as long I am in my spring world.
final String corrID = UUID.randomUUID().toString();
asyncJmsTemplate.send("test.RequestQ", new MessageCreator()
{
public Message createMessage(Session session) throws JMSException {
try {
MapMessage msg = session.createMapMessage();
msg.setStringProperty("json", mapper.writeValueAsString(List<of some objects>));
msg.setJMSCorrelationID(corrID);
msg.setJMSReplyTo(session.createQueue("test.ReplyQ"));
return msg;
} catch (JsonGenerationException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (JsonMappingException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return null;
}
});
BUT when I tried to implement this methods to my grails test app I receive some METHOD_DEF exceptions. Sending simple TextMessages via the jmsTemplate.convertAndSende(Queue, Message) provided by the JMS Plugin works.
Can any one help me? Is this a common problem?
Cheers Hans
