The easiest way is probably to specify configuration properties as Java annotations. Take a look at org.apache.sling.servlets.get.impl.DefaultGetServlet for (one of many) examples. In principle, all you need to do is have a string constant annotated as @scr.property (or @Property if you're using the 'real' annotations). Then create local variables to store the property values. These values are fetchted from the Felix ConfigAdmin on component activation. Let's look at the 'aliases' config property in DefaultGetServlet: /** @scr.property */ private static final String ALIAS_PROPERTY = "aliases"; // Name of the property ... private String[] aliases; // Local variable to hold the value ... protected void activate(ComponentContext ctx) { Dictionary props = ctx.getProperties(); // Set the local 'aliases' variable to the value from ConfigAdmin this.aliases = OsgiUtil.toStringArray(props.get(ALIAS_PROPERTY)); ... } protected void deactivate(ComponentContext ctx) { this.aliases = null; ... } In short, you don't need *.properties files. You can supply default values in the Java code itself, or you can supply configuration as JCR nodes. See http://sling.apache.org/site/jcr-installer-jcrjcrinstall-and-osgiinstaller.html#JCRInstaller%28jcr.jcrinstallandosgi.installer%29-Install%2Cmodifyandremoveaconfiguration for the docs.
