I'm trying to configure JBoss 3.2.4 to use SonicMQ4.0.2 as JMS provider. I followed the configuration guide provided by SonicMQ (supposedly to work with JBoss 3.2.1). But as soon as I drop the sample MDB jar in the deploy directory, I got the following error:

11:24:05,968 WARN [JBossMQProvider] JBossMQProvider is deprecated use JNDIProviderAdapter

Can anyone explain why I'm getting " java.lang.AbstractMethodError: com.sonicsw.pso.jboss.SonicMQServerSessionPoolFactory.ge
tServerSessionPool" ?
