raghutpk updated CONFIGURATION-467:
-----------------------------------
Comment: was deleted
(was: Thank you very much for the early response. I really apprecieate that.
The temporarily proposed solution doesn't seem to work on the scenario given. I
added the autoSave="true" for all the config sources in config.xml as
specified, but
{code:java}
combinedConfig.setProperty("Key","updatedValue");
{code}
doesn't still persist to the Filesystem.
{code:java}
System.out.println(combinedConfig.getProperty("Key"));
{code}
The above code will give me the updatedValue(but it is temporary as only the
object in memory is modified) but still I have no way to persist it back to the
filesyatem. Anthing else could be done to the CombinedConfig object so as to
acheieve the objective.
I can attach the screenshots if necessary

> Key: CONFIGURATION-467
> URL: https://issues.apache.org/jira/browse/CONFIGURATION-467
> Project: Commons Configuration
> Issue Type: Improvement
> Components: File reloading
> Affects Versions: 1.6
> Environment: Linux java
> Reporter: raghutpk
> Original Estimate: 24h
> Remaining Estimate: 24h
>
> I use a config.xml file to load multiple Configuration Sources
> Ex:
> {code:xml}
> <configuration>
> <header/>
> <override>
> <properties fileName="db.properties"/>
> <properties fileName="jms.properties"/>
> <xml fileName="gui.xml"/>
> </override>
> <additional/>
> </configuration>
> {code}
> I load the config.xml and subsequently all the properties in my app to a
> CombinedConfiguration Object as follows :
> {code:java}
> DefaultConfigurationBuilder builder = new DefaultConfigurationBuilder();
> builder.setFile(new File("config.xml"));
> CombinedConfiguration combinedConfig = builder.getConfiguration(true);
> {code}
> Now I am trying to expose all the properties from all configuration sources
> using a mbean and at runtime trying to update the Properties. I wouldn't know
> though, from which source the properties came from as the
> CombinedConfiguration takes care of that abstraction, but when I do the
> following it doesn't change the persistance store(in this case the files on
> the Filesystem).
> /*combinedConfig.setProperty(Key, updatedValue);*/
> There is no save method on the combinedConfiguration class so that the
> persistance store gets updated.
> There is a save method in PropertiesConfiguration class or XMLConfiguration
> class, but I wouldn't know at runtime or inside the code which file or
> configuration source the Key belongs to, so even If I add a config-name to
> each source there is no use.
> SO wouldn't the setProperty help me update the value of the Configuration and
> persist it back to the original file. I don't know it is a bug or a feature
> it doesn't support or there is a workaround in such scenarios.
> Please advice.
