The core of the jboss server is just a base microkernel (based on jmx in 4.0.x and earlier) along with a few (currently 5) core services. Anything else is functionality that must be loaded into the microkernel. In the 4.0.x versions of jboss the core services can be configured via xmbean descriptors found as resources in the server classpath under the name "xmdesc/"classname"-xmbean.xml.

Core services

• org.jboss.system.server.ServerInfo

• org.jboss.system.ServiceController

• org.jboss.deployment.MainDeployer

• org.jboss.deployment.SARDeployer
