Question

I’m working on CQ5 based app, which is a whole new area for me as I was mainly working on Spring based web-apps before.

The app is maven project based on Blue-prints archetype(http://www.cqblueprints.com/xwiki/bin/view/Blue+Prints/The+CQ+Project+Maven+Archetype).

Now I have a question, what is a standard approach to add some properties, that would normally go to config.properties (or alike) file in standard web-app. Properties that contain things like hostNames, accountNumbers and alike.

Cheers.

Thanks a lot to Bertrand, your answer really pointed me in the right direction.

What I did was I created .ConfigService.xml for each of my ran modes, which looks like that:

<?xml version="1.0" encoding="UTF-8"?>
<jcr:root xmlns:sling="http://sling.apache.org/jcr/sling/1.0"         xmlns:jcr="http://www.jcp.org/jcr/1.0"
jcr:primaryType="sling:OsgiConfig"
myconfig.config="{String}My Value"/>

Then in my ConfigService looked like that:

@Component(immediate = true, metatype = true)
@Service(ConfigService.class)
public class ConfigService {

    private Dictionary<String, String> properties;

    @SuppressWarnings("unchecked")
    protected void activate(ComponentContext context) {
        properties = context.getProperties();
    }

    protected void deactivate(ComponentContext context) {
        properties = null;
    }

    public String getProperty(String key) {
        return properties.get(key);     
    }
}

Than I just use ConfigService if I need to get a config property accessing it using @Reference.

I hope that can help someone!
