ActiveMQ without persistence

Hi,

I'd like to set up a publisher-subscriber based communication protocol between a server producing messages and many clients receiving them. After a bit of research, I decided to go with ActiveMQ. I looked at a few tutorials and the ActiveMQ site and set up the broker as follows:

BrokerService broker = new BrokerService();
broker.setPersistent(false);
broker.addConnector("tcp://localhost:61616");
broker.start();

I only need the message passing functionality, no database persistence or anything alike. However, when I start the application, a activemq-data folder is created regardless of the the configuration. This in turn causes an exception the next time I start the broker.

SEVERE: Failed to start ActiveMQ JMS Message Broker. Reason: java.io.EOFException: Chunk stream does not exist at page: 0

Is this a bug or am I not setting up the broker correctly (using ActiveMQ 5.4.1)? How can I disable persistence, so the additional data storage is not created? Also, I prefer to configure the broker from within the Java application and not through an xml file.

Cheers, Max

Thanks for your reply. Changing the persistence store would add another dependency for something I don't intend to use.

so basically you do not want persistence and it's not taking the code configuration. What i've read is that the setting will be ignored when a persistence adapter is set. Maybe you could try clearing the adapters ( incase one has been set by default, altough looking at the source, it uses the MemoryPersistence) before starting ? Other then that, i would say it is a bug an needs to be registered in jira :s
