[Configuration] CompositeConfiguration.getNumberOfConfigurations(
) question
Hello,
I'm using a CompositeConfiguration instance and I add two configurations to
it in my program.
I'm quite surprised to see that method
CompositeConfiguration.getNumberOfConfigurations() returns 3.
I guess the method counts the in memory configuration.
Do you think it is relevant to take the in memory configuration into
account?
If so, I guess it should be documented, isn't it? (it is not the case at the
moment)
Regards,
Seb' (who is sincerely graceful to all people involved in Jakarta commons
since it saved him lots of work)

The display is :
file:/C:/Documents%20and%20Settings/JMGuillemette/My%20Documents/Workspace/Config/ConfigDemo/bin/sample.properties
jamie
The file it self is not in a jar.. but it might be at distribution time...
hence why i was perfering to use URL for referencing the file.

Where is located the sample.properties file ? Inside a JAR ? Could you
show us the URL displayed by System.out.println(url) ?

[Configuration] save() not working?
Posted by Jamie Guillemette <JM...@hotmail.com>.
In follow up to my message of this morning here is some sample code.
[code]
/*
* Created on Apr 6, 2005
*/
package com.wirednorth.configdemo;
import java.net.URL;
import org.apache.commons.configuration.Configuration;
import org.apache.commons.configuration.ConfigurationException;
import org.apache.commons.configuration.PropertiesConfiguration;
/**
* @author JMGuillemette
*/
public class ConfigDemo {
public ConfigDemo(){
}
public void runDemo()throws ConfigurationException{
URL url = this.getClass().getResource("/sample.properties");
System.out.println(url);
PropertiesConfiguration config = new PropertiesConfiguration(url);
String firstName = config.getString("name.first");
System.out.println(firstName);
config.setProperty("name.first","newName");
config.save();
}
public static void main(String[] args)throws Exception{
ConfigDemo demo = new ConfigDemo();
demo.runDemo();
}
}
[/code]
the properties files it self looks like this...
[file]
name.first = jamie
name.last = guillemette
city = london
prov = ontario
[/file]
if you run this code.. you would expect the first run through to product
"jamie"on the console.. and the next one to produce "newName"... instead
what i get is "jamie" every time.
Thanks again for all you help everyone :)
J.

Re: [Configuration] CompositeConfiguration.getNumberOfConfigurations( ) question
Posted by Eric Pugh <ep...@opensourceconnections.com>.
Thats a good point.. However, sometimes you actually want to get back
the memory configuration... although, I guess that is mostly in the
unit tests when you want to do whitebox testing.. From an external
perspective, it does make sense that you would get back 2
configurations only!
