问题
I manually inject a properties file inside a jar. How to load properties from a jar file before java 1.7 ? I tried many workarounds and nothing worked so far.
There's plenty questions about it, but everything is focused on ClassLoader methods from java 1.7.

When you have a properties file inside your classpath or inside your jar file it becomes a resource. Any other case is a simple file.
What you need to do, before you package your jar file, is add to your classpath the folder where the properties files are (i.e myproject/src/main/resources/) then wherever you do a
Properties properties = new Properties();
properties.load(MyClass.class.getResourceAsStream("/yourPropsFileName"));
it will load it!
Although, if you are using an external property file you can also load it by using:
Properties properties = new Properties();
properties.load(new FileInputStream("extenalPropsFileLocation"));
Hope it helps!

From some class, call:
getClass().getResourceAsStream("/path/to/props.props")
Make sure that the path matches up with a classpath location.
