ranbir singh commented on CONFIGURATION-379:
--------------------------------------------

Thanks a lot for your prompt action. 
As required, please find below the code for configure method:
I have removed the exta code to avoid any confusion.

We call configure() method, which in turns call  configure(String path) .

public class CIMConfiguration 
{

....
private PropertiesConfiguration config = null;
....

	public CIMConfiguration configure() {
		String configFile = System.getProperty(CIM_CONFIG_FILE);
		if (!StringUtils.isBlank(configFile)) configure(configFile);
		else configure("cim.properties");
		return this;
	}

	public CIMConfiguration configure(String path) {
		URL url = ConfigurationUtils.locate(path);
		config = new PropertiesConfiguration();
		config.setURL(url);
		try {
			log.info("Loading configuration ["+url+"]...");
			config.load();
		} catch (ConfigurationException e) {
			e.printStackTrace();
			
			log.warn(path + " open error",e);
			
			throw new CIMException(e);
		}
		return this;
	}

FYI: 
The line "log.info("Loading configuration ["+url+"]...");" prints 
" Loading configuration [file:/D:/applications/CIM/CIM-Config/cim.properties]..."
correctly and the file exists at that location.
