Hi all,

Today I’m focusing my attention on ADF naming conventions.

Beside this post I will write two more to cover as much as possible all areas of this subject. In the last post I will provide a PDF with all information covered in these series of posts.


During ADF applications development we may encounter many development challenges. One of these challenges is about implementing a naming convention to be used by all project developers involved during implementation.

Each developer have his own background and his own ideas on how things should be implemented. We want them to have freedom of thought in order to get the best approaches to reach the goal, but what we really don’t want is to have multiple ways of doing the same thing, otherwise we might face really difficult challenges in the future, namely around software maintenance and bug tracing.

Also, the developer roster may change during project development. For the new ones who join we need to provide proper training. If we can follow conventions we will have shorter training periods and they will be brought to speed quicker while familiarizing with the application.

After the application is deployed in the production environment, we face a new challenge, Maintenance and Support. Big headaches usually start right there, and they can be even bigger if we don’t follow these important naming conventions in our applications’ code.

I have found some information here about this topic but we needed more, and we needed to instantiate it to our projects, so we decided to defined our own ADF Naming Conventions, to be used organization-wide on our ADF projects.

In this post I will share my experience and our ADF Naming convention rules regarding the following topics:

  • Application & Project Naming
  • Packages Naming
  • Business Components Naming


Consider the following terms used in these series of posts:

Abbreviation Definition Example
PROJECT_NAME Customer or project’s short name. Try to use only the necessary characters that are able to describe your customer/project so that everyone can understand it.  RMK (Red Mavericks)
MODULE_NAME Provide a name that describes the target of the project (module).  MyAdfLib
DOMAIN_NAME Internet domain name.  red.mavericks
BUSINESS_AREA Feature Business area (retail, financial, etc.)  retail/financial

Application & Project Naming

For Applications and Projects we defined the following naming rules:

Application Project

Example: RMKMyAdfLib

IMPORTANT NOTE: For both previous naming rules, decide if they should be in upper case, lower case or camel case. Once you do, stick to it!


Packages Naming

In the wizard for creating a new application, you are prompted to set up the “Application Package Prefix“. This package prefix will define the root package for the projects contained in this new application.

The default “Application Package Prefix” for new applications should be:


Example: red.mavericks.rmk

For each new project, you will inherit the application’s root package structure. Nevertheless you should configure it to have a distinct name from other projects. With this, you are able to identify your modules/libraries. The package structure for your project should follow the next pattern:


Example: red.mavericks.rmk.my.adf.lib


Business Components Naming

For this topic, we will provide our proposed package structure and file naming rules for Business Components.

IMPORTANT NOTE: Files should be named in camel case.

Packages Structure

For Business Components projects, we should gather Entity ObjectsView ObjectsView Links and Associations under the following packages::

Type Package Description
 Entity Associations  <DOMAIN_NAME>+ . +<PROJECT_NAME>+ . +<MODULE_NAME>adfc.entity.associations  Contain entity associations
 Entity Objects  <DOMAIN_NAME>+ . +<PROJECT_NAME>+ . +<MODULE_NAME>adfc.entity.objects  Contain entity objects
 View Links  <DOMAIN_NAME>+ . +<PROJECT_NAME>+ . +<MODULE_NAME>adfc.view.links  Contain view links
 View Objects  <DOMAIN_NAME>+ . +<PROJECT_NAME>+ . +<MODULE_NAME>adfc.view.objects  Contain view objects
 Model JPX File  <DOMAIN_NAME>+ . +<PROJECT_NAME>+ . +<MODULE_NAME>adfc  Contain model JPX file


Entity Associations:  red.mavericks.rmk.my.adf.lib.adfc.entity.associations
 Entity Objects:  red.mavericks.rmk.my.adf.lib.adfc.entity.objects
 View Links:  red.mavericks.rmk.my.adf.lib.adfc.view.links
 View Objects:  red.mavericks.rmk.my.adf.lib.adfc.view.objects
 Model’s JPX File:  red.mavericks.rmk.my.adf.lib.adfc

File Naming

For each Business Component type, you should provide the following prefixes:

File Type Suffix Example
 Entity Associations  Assoc  SomeNameAssoc
 Entity Objects  EO  SomeNameEO
 View Links  VL  SomeNameVL
 View Objects  VO  SomeNameVO
 List Of Values  LOV SomeNameLOV
 Model JPX File  Equal to project’s name

View Link File Naming

View Link names should be self-explanatory so we can easily identify their purpose. Based on this we defined the following pattern::

<ViewObjectSourceName> + <ViewObjectDestinationName> + VL

Example: EmployeeEmployeeBranchVL


Application Modules

You may have multiple “Application Modules” in your application. For this case we should be able to identify their purpose as well as their business area target. Based on this we followed the next pattern:


Example: RMKMyAdfLibAM

In my next post I will talk about:

  • Model & View Controller Projects
