While you are creating a new business component project or package, use the Package Name page to specify the name of the package. This is the initial package object that will be added to your project.
JDeveloper provides a default name for the package. You can accept
the default or you can enter a single word name, such as myPackage,
or a "dot-separated" name of the form oracle.jbo.server.
JDeveloper will create the necessary directories if they do not
already exist.
