I'm writing a converter which should convert file A to file B. Doing so, I'm using the config API from Apache Commons Configuration to filter those files so not every entry will be converted.
Now I made a jar file which has the config file inside it. Reading from this config file inside the jar is no problem but if I try to use the save() method I'll get a ConfigurationException: no file name has been set message.
If I try to set the file name programmatically the program throws a NullPointerException.
So my question is: can I modify an e.g. config.properties file inside my jar in a programatic way?
