About Packaging Components

About Packaging Application Components

A J2EE application consists of standardized components such as WARs and JARs. To assemble an application that can be deployed, you first package application components (WAR/JAR) into modules according to the container that will receive them.

A module is comprised of one or more J2EE components with J2EE and iAS-specific deployment descriptor files.

The application-level deployment descriptor lists the modules included in the application and reconciles J2EE module deployment descriptors, if necessary.

A web module (WAR) consists of:

servlets
JavaServer Pages (JSP)
Tag libraries
HTML pages
images
Classes and other resources

An EJB module (JAR) consists of:

EJB classes
helper files
other resources used by the bean

You can deploy individual components and component libraries when they are packaged into a module.

The following is a graphical representation of the deployment packaging.
