First, try:   ClassLoader.getResourceAsStream ("some/pkg/resource.properties");   Class.getResourceAsStream ("/some/pkg/resource.properties");   ResourceBundle.getBundle ("some.pkg.resource"); Additionally, if the code is in a class within a some.pkg Java package, then the following works as well:   Class.getResourceAsStream ("resource.properties"); Behavioral differences Method Parameter format Lookup failure behavior Usage example ClassLoader. getResourceAsStream() "/"-separated names; no leading "/" (all names are absolute) Silent (returns null) this.getClass().getClassLoader() .getResourceAsStream ("some/pkg/resource.properties") Class. getResourceAsStream() "/"-separated names; leading "/" indicates absolute names; all other names are relative to the class's package Silent (returns null) this.getClass() .getResourceAsStream ("resource.properties") ResourceBundle. getBundle() "."-separated names; all names are absolute; .properties suffix is implied Throws unchecked java.util.MissingResourceException ResourceBundle.getBundle ("some.pkg.resource")
