Using the wizard to create an enterprise
application project allows you to package many web applications and modules
in a project and deploy these modules as a J2EE enterprise application.
application projects contain references to the resources needed for enterprise
applications and can contain a combination of Web modules, JAR files, connector
modules, EJB modules, and application client modules. An enterprise application
project is deployed in the form of an EAR file, and is therefore sometimes
referred to as an EAR project. The modules in an enterprise application project
are mapped to other J2EE projects. The mapping information is stored in metadata
files within the enterprise application project. The metadata files are used
for exporting the project to an EAR file and for running the project on the
Like the other types of projects, enterprise application projects
can contain one or more project facets, which represent units of functionality
in the project. To be deployed as an EAR file, the new project must have the
EAR facet. Depending on what you want to use the project for, you may want
to enable other facets for the project.
