When I read the source code of class org.jboss.ejb3.embedded.resource.RARDeployment, I found the resourceAdapter's endpointActivation was called in method invoke, but one thing I was confused was where the parameter 'messageEndpointFactory' comes from? Standardjboss.xml gave me some clue: <invoker-proxy-binding> message-inflow-driven-bean <invoker-mbean>default</invoker-mbean> <proxy-factory>org.jboss.ejb.plugins.inflow.JBossMessageEndpointFactory</proxy-factory> Could anyone tell me what's happening during the initialization of resource adapter endpoint?
