You can use the tools in the workspace to define the module
dependencies in the Java™ EE
project in your workspace.
Application deployment descriptor editor
While deployment descriptors
are not required in Java EE
as they were in J2EE, you can include deployment descriptors in your
enterprise applications, and change to your module dependencies using
the deployment descriptor editor.
Specifying dependent JAR files or modules
You can use the Java EE Module
Dependencies page to specify JAR files or modules that are required
by a module. The dependencies are defined in the MANIFEST.MF file
for your module.
