Question

You can create custom environment installer variables using a <setInstallerVariable> action. For example:

<setInstallerVariable>
           <name>serverport</name>
           <value>3306</value>
        </setInstallerVariable>
        

The code above will create an installer environment variable called serverport , which can later be referred to as ${serverport}. Wherever it appears, it will be substituted for its value during installation.
