ClassCastException when casting to SpyConnectionFactory

[rtrauni]

Using following cast

factory = (SpyConnectionFactory) ctx.lookup("ConnectionFactory");

if always get following classcastexception:

Caused by: java.lang.ClassCastException: org.jboss.mq.SpyConnectionFactory
 at at.maat.commons.remoting.jms.JMSGateway.start(JMSGateway.java:84)
 ... 20 more

The strange thing is that both, ctx.lookup("ConnectionFactory") and the cast (SpyConnectionFactory) are of type org.jboss.mq.SpyConnectionFactory

Any ideas?

Duplicate .jar files deployed? And why do you need to cast it, cast it to javax.jms.ConnectionFactory .
