PropertiesConfiguration how to reference config.properties - apache

Question

I am new to Java so forgive me for my lack of knowledge. I am trying to utilize a properties file in my web app. While researching I found this article http://commons.apache.org/configuration/howto_properties.html which seemed pretty straight forward so I attempted to implement this. I attempted to implement as follows :
Configuration config = new PropertiesConfiguration("stream.bundle.config");
I have tried stream.bundle.config, bundle.config and many other combinations but every time I get back an exception that says Cannot locate configuration source. The file is in a folder under src called bundle. My question is a) where should the file be? b) how should I reference it. I apologize for my lack of knowledge. Thanks in advance.
update:
I also tried
FileInputStream in;
Properties p = new Properties();
try{
in = new FileInputStream("config.properties");
p.load(in);
}
catch(Exception e){
System.out.println("Error: " + e);
}
and I get java.io.FileNotFoundException: config.properties (The system cannot find the file specified) or java.io.FileNotFoundException: config (The system cannot find the file specified)

Answer 1

Regarding a) where should the file be:
in the current directory
in the user home directory
in the classpath
If you consider using Java's Properties you have to get an InputStream some way. If you're loading the properties from a class in the package, you have to use:
getClass().getResourceAsStream("resource.properties");
and if the class is in another package:
getClass().getResourceAsStream("some/pkg/resource.properties");
You can try loading the properties via the ClassLoader:
ClassLoader.getResourceAsStream ("some/pkg/resource.properties");
If you have a ServletContext, you can use:
ServletContext.getResourceAsStream(..)
EDIT: you should reference your file by the full name (filename+extension). So your first
try should have been:
Configuration config = new PropertiesConfiguration("config.properties");

Try this:
Properties properties = new Properties();
try
{
properties.load(Thread.currentThread().getContextClassLoader().getResourceAsStream("xyz.properties"));
}
catch (IOException e)
{
// TODO Auto-generated catch block
e.printStackTrace();
}
