> Hi 
> This issue is really grappling me. I use  Apache commons configuration to read the \
> configuration for my application. I expose my configuration through a jmx client so \
> that I can change the configuration at runtime and would like to persist the \
> changes to the original load form. I have multiple configuration sources so I use a \
> CombinedConfiguration object to read in my config.xml file. I have wrapped custom \
> logic and rules to save the confgiuration to the persistent store. I use Jboss AS5 \
> to deploy my application.  All is well when I have configuration files in the \
> filesystem outside  $JBOSS-HOME/server/default/deploy. I am able to read fine and \
> write back to the config files fine too.  but the problem is when I bring in the \
> Config files in the following directoy \
> $JBOSS-HOME/server/default/deploy/{application-name}/.. I can read the \
> configuration fine, but when I try to write the configuration back to the \
> persistent store using the save method of the respective configuration(like \
> PropertiesConfiguration & XMLConfiguration) using a jmx client(I also tried to \
> harcode and save within code immediatly after reading my configuration). I keep \
>                 getting the follwing exception :
> java.net.UnknownServiceException: protocol doesn't support output
> 	at java.net.URLConnection.getOutputStream(URLConnection.java:792)
> 	at org.apache.commons.configuration.DefaultFileSystem.getOutputStream(DefaultFileSystem.java:113)
>   at org.apache.commons.configuration.AbstractFileConfiguration.save(AbstractFileConfiguration.java:461)
>   at org.apache.commons.configuration.AbstractFileConfiguration.save(AbstractFileConfiguration.java:402)
>   at org.apache.commons.configuration.AbstractFileConfiguration.possiblySave(AbstractFileConfiguration.java:737)
>   at org.apache.commons.configuration.AbstractFileConfiguration.clearProperty(AbstractFileConfiguration.java:784)
>   at org.apache.commons.configuration.AbstractConfiguration.setProperty(AbstractConfiguration.java:483)

> Please throw some light on the exception because it is helping me nowhere in \
> understanding the issue If I am able to read it, I should also be able to save it \
> back..but it is not happening within JBOSS directory(I can only read). Moment I \
> shift my configurations outside that to a different place in the Filesystem say \
> /home/../Config and also keep the config.xml(containing the reference to the \
> Configuration sources)it is perfectly working fine. This is being a blocker for me. \
> I may have completely misread the scenario, so please throw light on the same if I \
> am missing anything or more details are needed. Following is the piece of code used \
>                 to read the configuration :
> ...
> builder.setFile(new File(Path to CONFIG_DIRECTORY +
> 		  CONFIG_DEFINITION_FILENAME(config.xml)));
> CombinedConfiguration combinedConfig = builder.getConfiguration(true); 
> sample config.xml file : 
> <?xml version="1.0" encoding="ISO-8859-1"?>
> <configuration>
> 	<header />
> 	<override>
> 		<properties
> 			fileName="db.properties"
> 			autoSave="true" config-name="properties1" />
> 	<properties
> 			fileName="jms.properties"
> 			autoSave="true" config-name="properties2" />
> 		<properties
> 			fileName="test.xml"
> 			autoSave="true" config-name="properties3" />
> 		<xml fileName="gui.xml"
> 			autoSave="true" config-name="xml1" />
> 	</override>
> 	<additional />
> </configuration>
> Following is sample code used to write back updated values to the persistent store \
> :  xmlConfig = (XMLConfiguration) combinedConfig.getConfiguration("configuration \
> source name");;  if (xmlConfig.containsKey(key)) {
> 								try {
> 									// Update the value.
> 									xmlConfig.setProperty(key, value);
> 									xmlConfig.save();
