Developing J2EE applications - IntelliJ IDEA in Action - page 401

Configuring the J2EE application module
Not all modules may exist at the time the J2EE application module is created. In
this case, you can add modules manually using the File | Settings: Project Set-
tings: Paths: J2EE Application Module Settings tab.
In the Modules and Libraries to Package section, mark as Include module in
build the modules you need (see figure 11.14).
Editing J2EE deployment descriptors
Like web and EJB modules, J2EE application modules have deployment descrip-
tors. To fine-tune the J2EE application deployment process (introducing/chang-
ing security roles), you may need to introduce changes in them either in a graphic
editor or manually.
Figure 11.14 Main configuration settings for an application module. The most important field is the
table where you can edit the modules and libraries that are to be packaged into the deployed module
and the method of doing so.
