J2EE is a platform that helps us to develop and deploy enterprise application.It follows the component based architecure.
So, it means that an application is developed in components in order to acheive reusability if needed. I am aware that these components make use of the containers to achieve the low level funcinality required for the components.
My question now is
I read something like this " before a application client component can be executed, it must be configured as j2ee service and deployed into its container."
What does configure as j2ee service mean ?? Do the application need to be defined as a service just like the other standard services in j2ee.
Since, we are developing an application making use of most of the available standard services of j2ee why do we need to configure the appilcation or its components as a j2ee service.
