Answer 1

This is my file structure within the Maven project:

src/main/resources/
src/main/resources/META-INF
src/main/resources/adir
src/main/resources/adir/afile.json

Finally,this worked for me:

String resourceName = "adir/afile.json";
ClassLoader classLoader = Thread.currentThread().getContextClassLoader();
URL resource = classLoader.getResource(resourceName);
InputStream iStream = resource.openStream();
byte[] contents = iStream.readAllBytes();
System.out.println(new String(contents));

Since you're using Maven, files from src/main/resources will end up on the classpath automatically.

To load a resource from the classpath, use something like this:

InputStream in = getClass().getResourceAsStream("/image.jpg");

Getting the path to the resource or opening it as a File may not always work though since the file is probably still stored inside a .war file. class.getResource() will therefore return a URL that is recognizable only by the app server's classloader.
