Did you try to call something like prop.store(new FileOutputStream("config.properties"), null);after calling prop.setProperty method? Because it's the way you flush changes to file.

Without calling store changes are visible only in application memory.

SetProperty() will only set the property during the runtime. It will not go and override your file property. It wont modify your file.

You need to write the properties file again using store() (of which there are two variants). The setProperty() method changes the value of property stored in memory, not the value of the property in the file the properties were loaded from.

For further reading see the Properties Tutorial.
