What about if you try this kernel name: | /** The default kernel name */ | static final String KERNEL_NAME = "jboss.kernel:service=Kernel"; | But I think this is what your problem falls in: - http://www.jboss.com/index.html?module=bb&op=viewtopic&t=105189&a... Maybe the only difference is that you want to access 'core' kernel, and not new one created from "Bean Deployer". Where's this code that you want this? Where do you get mainDeployer?
