Java EE Application Design with Java 9

What is the best way to design (Structure) a JAVA EE Application with Java 9.

I have tried to search for compatible answers but had no luck.

Current Structure contains the following

• Parent with

  <modules>
    <module>Proj-ear</module>
    <module>Proj-ejb</module>
    <module>Proj-entities</module>
    <module>Proj-web</module>
  </modules>
  
  

I have several entity groups relating to each other that i want to use in a modular way. Any advice and guidance will be appreciated.
