Using the code:
System.getProperty("user.dir")+"\email\email.properties"
It picks up from the user
(C:\USUARIO\user\Documents\Netbeans\Projeto\email\email.properties)
But what if it is in the drive C:\ only?
(C:\Email\email\email.properties)
How do I System.getProperty get wherever I am?
To get the path of the folder where .jar is running you should use the following code, changing MinhaClasse to the current class name:
MinhaClasse
.class
.getProtectionDomain()
.getCodeSource()
.getLocation()
.getPath()
.getParent() + "\email\email.properties";
To return the drive letter where the system is installed
System.getenv("SystemDrive");
SystemDrive is a Windows environment variable, you can capture the value of any of the variables.
