A J2EE application(s) can be executed by the J2EE application servers, and a J2EE application container(s) are contained within each J2EE application server. Each J2EE application container contains a J2EE application container component(s) and a Java EJB container(s) or Java web containers are contained within each J2EE application container. A J2EE component(s) are delivered to the J2EE application server over one or more tiers of the network. There are one or more logical connections to one or more databases located on the network. This defines a sphere of control managing transactional deployment of the delivered J2EE component(s) and an update of the database to keep the data consistent with the J2EE application.
