Project variables function as placeholders, having values that are determined when you create a specific Deployment Profile. Project variables can be literals or Environmental constants, as described in Defining Environmental Constants.
As an example, the following figure shows a Project variable defined to represent a password of a database user in a target Environment. A system manager assigns an actual value to this variable in the Deployment Profile editor. The value of the assigned Project variable (an Environmental constant) is then used to connect to the database in the target Environment.
You can add a variable to a Project by selecting the New > Variable or Constant option from the Project context menu in the NetBeans IDE, which displays the following dialog box.
