I am using properties file to set the configuartion for a small java application. At present the properties files lie in a package (called 'config') within the src folder. So the structure is

Project folder
                   |
                   - src
                         |
                         --com.abc.util (this is where the java class files are)
                         |
                         |
                         - config (this is where the properties files are, this is within the src folder)

I want to distribute this application as a jar. I want to the keep the properties files under the project folder directly not within the src folder. I s this a good practise?

Also is am using the following code to read and load the properties files.
InputStream propertyStream = PropertyLoader.class.getClassLoader()
				.getResourceAsStream(propertyFile);

		Properties properties = new Properties();
		try {
			properties.load(propertyStream);
		} catch (IOException e) {
			throw new RuntimeException(e.getMessage());
		}

How do i change the code to read files contained outside the src folder?

It is a normal practice. For example, log4j and many other does the same

you can (and should) move it out of the source folder. With you're current code you need to include somewhere in your classpath

String path = getClass().getProtectionDomain().getCodeSource().getLocation().getPath();	
		String[] arrPath=path.split("/");
		String projectFolderPath="";
		for (int i=0;i<=arrPath.length-2;i++)
			projectFolderPath=projectFolderPath+arrPath[i]+"/";			
		
		
		InputStream propertyStream = PropertyLoader.class.getClassLoader()
				.getResourceAsStream(propertyFile);

		Properties properties = new Properties();
		try {
			java.io.FileInputStream fis = new java.io.FileInputStream
			   (new java.io.File( projectFolderPath + propertyFile));
			properties.load(fis);
		} catch (IOException e) {
			throw new RuntimeException(e.getMessage());
		}
		return properties;
	}

It seems to be working. I have placed the properties files in folder config under the project folder. Is this what you mean gurvinder?

Not necessarily. You can keep it anywhere in your file system from where your program have the permissions to access that location.

but will it work when you deploy the application?
The advantage of the code you were originally using is that it would search the classpath for the file.
