You are missing the actual deployer (structure). You need something like this: | deploy --> jboss-spring.deployer | --> jboss-spring-jdk5.jar | --> META-INF --> jboss-service.xml | In the jboss-service.xml there is a description of SpringDeployer. See the first version of deployer archive, at least for the structure. Then the new jboss-spring-jdk5.jar is just new code compatible with new Spring2.0 release.
