   2. ResourceBundle bundle = Util.getBundle("/opt/","log4j"); //Fetches log4j.properties from /opt.

   3. Map<String, String> propertiesMap = Util.getProperties("/opt","log4j"); //Loads all the key-values in /opt/log4j.properties to propertiesMap

   4. String propertyValue = Util.getProperty("/opt", "log4j", "log4j.rootLogger"); //Gets the value of the key log4j.rootLogger from /opt/log4j.properties

   5. Object obj = Util.invokeMethodOfClassInJar("/opt/myjar.jar","com.test.MyClass","mymethod", null); //Invokes com.test.MyClass.mymethod() from /opt/myjar.jar
