[Configuration] CompositeConfiguration - setting FileChangedReloadingStrategy
on each XMLConfigurationHey everyone,
I downloaded the commons configuration project a few days ago in hopes of using
it to create a generic configuration interface.
In order to achieve this, I need an api that can a) read configuration
information from multiple datasources b) save changes back to the original
datasources. (which sounds exaclty what the configuration project is all about)
In experimenting with the api I've come across serval serveral inconsitencies
with the save() feature... (ive had no problem with simply reading values)
a) if your project is devided into src / bin and the root of the running path
is neither of these.. save a properties file will result in a new file being
created in the root or the current running path.. not overiding the existing
file.
b) if you use URL to load your configuration ie
URL url2 = this.getClass().getResource("/sample.properties");
config.addConfiguration(new PropertiesConfiguration(url2));
when saving...two things happen. 1) the file is not saved. 2) the in memmory
representation of the values all become null. (where previous to the save you
could retreive the values without issue)
Its seems like there is a major bug in the save() logic ... worst yet..
whatever problem that is being encountered is not throwing a configuration
exception.
If everyone agrees.. i would like to take a serious look at the existing save
logic for each configuration type add the following:
i) make any adjustments necessary to guarrentee that where the configuration
data is read from is where it is saved to reguardless of project layout.
ii) add save() to CompositeConfiguration that will delegate down to all
configurations under its control.
Let me know your thoughts guys.
J.
