Emmanuel Bourg updated CONFIGURATION-467:
-----------------------------------------
Description:
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.
