You have both spring and spring-context on your classpath. Don't, either use spring (which contains almost everything) or use seperate modules (spring-context etc.). Also make sure you don't have conflicting spring versions in yuor classpath (check with mvcn depenency:tree). — M. Deinum
Thanks Deinum. It seems like a conflicting problem and I am resolving it. — Duleendra

I downloaded the activemq-core-5.0-SNAPSHOT pom.xml. It uses Spring 2.0.6 as the dependencies. I see that you have Spring 2.5.6 SEC02 as your spring dependencies.

Based on the activeMQ pom file i would believe you would have to use spring 2.0.6 as the dependencies and not 2.5.6?

As for the actual problem of your namespace not being resolved, it is generally a problem with the dependencies not being present in the classpath. In this case since active mq uses Spring 2.0.6 it isnt there in the classpath.
