Subject ObjectMessage looses object
Date Wed, 28 Nov 2007 11:03:22 GMT

Hello,

thank you for your time. I have no idea what I can do next. 
i try to send an ObjectMessage with a Serializable Object. this works fine
if I run my tests in "batch"-mode, but if I do the same in an eclipse
plugin, I revieve the message, but getObject()
throws an Exception. 

thank you

Thomas


this is what I do:

the connection:
ActiveMQConnectionFactory connectionFactory = new
ActiveMQConnectionFactory(user, password, url);
connection = connectionFactory.createConnection(user, password);
connection.start();
session =connection..createSession(false,Session.AUTO_ACKNOWLEDGE);
queue = session.createQueue(destinationName);
producer = session.createProducer(queue);
ObjectMessage message = session.createObjectMessage(msg);
producer.send(message);

the exception:
