Ralph,

Even I saw that and the FCStrategy issue where  vfs is taken instead of file 
when I use the Url concept. Then I changed to setFileName. I also used 
configurationutil.locate which actually gave file notfound if I remember. After 
struggling for 2 weeks I am confused the use of this commons configuration 
tool. My aim is to change a value in property file and get this reflect 
application wide without restarting JBOSS/app server. I am writing some simple 
junit before deploying to server and that itself is not working. I was 
expecting a simple framework without me doing the polling etc.


Regards
Sj

Even the listener is triggered by something retrieving a property. There is no

However, if you are using this with JBoss 5+ I'm not sure the code below will 
work. I've had developers reporting that JBoss is returning vfsfile as the 
protocol when the name is turned into a URL and then 
ConfigurationUtil.fileFromURL fails.  They have reported that using 
VFSFileChangedReloadingStrategy works fine with JBoss, although it isn't clear 
to me why since it doesn't explicitly support the vfsfile protocol.

Oliver,

Thanks so i misunderstood the reload startegies. But what about the listeners. 
Can we trigger signal to reload. I wanted to use ConfigurationChangedListener. 
But that still doesnt solve the purpose right. For more clarity i am pasting 
the unit test i wrote:

@Test
public  void  testGetBuiltPropertyFileName() throws Exception {
 PropertiesConfiguration config = new PropertiesConfiguration(); 
 Properties props = null;
 config.setFileName(TEST_FILE);    
 config.load(); 
 FileChangedReloadingStrategy strategy = new FileChangedReloadingStrategy(); 
 strategy.setRefreshDelay(500); 
 config.setReloadingStrategy(strategy);       
 assertEquals(config.getString("JEDI_ENVIRONMENT"),"TEST");
 props = ConfigurationConverter.getProperties(config);
 assertEquals(props.getProperty("JEDI_ENVIRONMENT"),"TEST");
 Thread.sleep(200000); 
 assertEquals(config.getString("JEDI_ENVIRONMENT"),"TEST");
 System.out.println("Test");
 assertEquals(props.getProperty("JEDI_ENVIRONMENT"),"TEST");
}

Oliver,

Thanks for the reply. I wrote a JUNIT test and Below is the code. My aim was 
that when i set the refresh delay to 500 and after the initial test passed i 
put a thread.sleep for 2 minutes. when  the thread sleeps i am changing the 
value of the  JEDI_ENVIRONMENT to some thing else. When the thread wakes up I 
wanted to see the props refreshed with new values so that the tes tcase fails 
which means the program runs as expected. Pls help me.

Hi Srinivas,

somehow your code got mangled, so it is hardly readable.

But if I understand correctly, you obtain a Properties object from the 
configuration using something like

Properties props = ConfigurationConverter.getProperties(config);

Then you expect that the properties are automatically refreshed by the 
reloading strategy without any further action from your side, correct?

Well, the reloading strategies do not work that way unfortunately. 
Currently, there is no implementation which actively monitors a 
configuration file. Rather, the reloading strategy is only triggered 
when the configuration object is accessed, e.g. if a property is 
queried. FileChangedReloadingStrategy then checks the timestamp of the 
configuration file. If it has changed, it reloads the configuration. So 
you will only see new values if you query the configuration again.

HTH
Oliver

Hi,

Below is the code for i wrote and seems at the propsConfig object gets refreshd 
after the delay but the result object has the old values still. How do i get 
the new values into the result object after the refresh. I am trying to create 
a Configuration listener as well and that alos seems not to work.  The main 
objective for me is to get the properties object loaded with new values without 
JBOSS server restart. Any help is appreciated.


Regards,
Srinivas J

your code looks good, therefore I am not sure whether I fully understand
your problem.

How can you tell that the properties configuration object is refreshed
correctly when the result object still has the old values? Do you get
other results if you access the configuration object directly, e.g. by
calling propsConfig.getString("someKey") ? (If so, this would indicate a
bug in the ConfigurationConverter.getProperties() implementation.)

Oliver


Properties result = null;
Configuration config = null;
URL resourceURL = null;
FileChangedReloadingStrategy refreshStrategy = new 
FileChangedReloadingStrategy();
refreshStrategy.setRefreshDelay(refreshDelay);

PropertiesConfiguration propsConfig = new PropertiesConfiguration();
propsConfig.setFileName(name);
propsConfig.load();
propsConfig.setReloadingStrategy(refreshStrategy);
result = ConfigurationConverter.getProperties(propsConfig);
