factory:java.io.IOException: Could not find factory class for resource: META-INF/services/org...

[aslam <ak...@gmail.com>]

I'm trying to use the VM Transport, launched in a JUnit TestSetup. Here's how
I create the broker:

String brokerUri =
"vm://localhost?brokerConfig=xbean:file:../mtx-unit-test/testing/activemq/activemq.xml";
BrokerService broker = BrokerFactory.createBroker(new URI(brokerUri));

This causes the following exception:
java.io.IOException: Could load vm factory:java.io.IOException: Could not
find factory class for resource:
META-INF/services/org/apache/activemq/broker/vm
	at
org.apache.activemq.util.IOExceptionSupport.create(IOExceptionSupport.java:27)
	at
org.apache.activemq.broker.BrokerFactory.createBrokerFactoryHandler(BrokerFactory.java:43)
	at
org.apache.activemq.broker.BrokerFactory.createBroker(BrokerFactory.java:70)
	at
org.apache.activemq.broker.BrokerFactory.createBroker(BrokerFactory.java:54)
...[truncated]
Caused by: java.io.IOException: Could not find factory class for resource:

	at
org.apache.activemq.util.FactoryFinder.doFindFactoryProperies(FactoryFinder.java:92)
	at
org.apache.activemq.util.FactoryFinder.newInstance(FactoryFinder.java:52)

The only info I could find on this is:
http://activemq.apache.org/ioexception-could-not-find-class-for-resource.html
...which says that I need to have the distro jar in my classpath. I have
both, activemq-core-5.0.0.jar and activemq-all-5.0.0.jar in the classpath.

What else should I check?

Re: factory:java.io.IOException: Could not find factory class for resource: META-INF/services/org...

[aslam <ak...@gmail.com>]

None of the jars have the 'vm' file where it's expected:
META-INF/services/org/apache/activemq/broker/vm

META-INF/services/org/apache/activemq/broker/ has only the following four
files:
- agent
- broker
- properties
- xbean

There's a 'vm' file in META-INF/services/org/apache/activemq/transport. I
copied this to the META-INF/**/broker directory, which resulted in...
java.io.IOException: Could load vm factory:java.lang.ClassCastException:
org.apache.activemq.transport.vm.VMTransportFactory

Given this, I'm not sure whether starting an embedded broker using the vm
transport and configuring it using an external configuration file --
http://activemq.apache.org/vm-transport-reference.html -- works.

Any ideas?

Next, I'll try doing this in one of the alternate ways.
