I suggest you go through the tutorials, the first two will do.
Just follow them, step by step trying to understand them, it should all be clear to you after finishing them.

SimpleConfiguration recognizes and de-references properties with the format: ${xxx} and searches for a system property, or operating system environment variable under the xxx name. As a fallback mechanism of last resort, the property can be resolved from an environment file, in YAML or properties file syntax, found in the cfg directory (default filename default.yml or default.cfg, which can be overridden by the jpos.env system property).
You can add a default value within the expression itself, using the : (colon) separator. For example ${xxx:def_value}. If the property is not found, the default value will be used.
The format $sys{xxx} de-references just from system properties, $env{xxx} just from the operating system environment, and $cfg{xxx} just from the environment file (the.
In the rare case where a value with the format ${...} is required, the $verb{${...}} format (verbatim) can be used.
In addition, a property named xx.yy.zz can be overridden by the environment variable XX_YY_ZZ (note that dots are replaced by underscore, and property name is converted to uppercase.
