J2EE Clients
J2EE clients are those applications, components, systems, and services that access the J2EE environment to fulfill a request or access a service. Depending upon the scope and horizons of a given enterprise J2EE environment, they can range from simple HTTP requests to complex interactions between several J2EE servers across the networks.
Types of J2EE Client Access..............
Accessing business logic services in EJB
Accessing presentation logic services
Accessing enterprise services
Accessing EIS services through J2EE
Example: Let us say we have a Siebel CRM system in the back end, and we access the resources through messaging systems/Siebel adapters. It is possible to construct access gateways inside J2EE—by making use of JMS, EJBs, and other Java libraries—so that Siebel resources can be accessed by a wide variety of Java clients and other applications in a consistent manner.
