Subject Error message about ActiveMQConnectionFactory
Date Sat, 18 Jun 2011 13:01:27 GMT
Hi All, 

I am new to Java and Activemq, and i try to create a message queue
application in eclipse. I copy code from
http://activemq.apache.org/hello-world.html.

But i can't make it work, i have added activemq-all-5.5.0.jar and
slf4j-log4j12-1.6.1.jar file. but i got a error as below:

Exception in thread "Thread-0" java.lang.NoClassDefFoundError: Could not
initialize class org.apache.activemq.ActiveMQPrefetchPolicy
	at
org.apache.activemq.ActiveMQConnectionFactory.<init>(ActiveMQConnectionFactory.java:88)
	at
org.apache.activemq.ActiveMQConnectionFactory.<init>(ActiveMQConnectionFactory.java:131)
	at Publisher$HelloWorldProducer.run(Publisher.java:59)
	at java.lang.Thread.run(Unknown Source)

Can anyone give me a help?

by the way, i am not sure whether it is caused by "JNDI", i don't really
know what is it. But i saw it in 
http://activemq.apache.org/initial-configuration.html.
