How can I access a file in WEB-INF/META-INF in a java web app?

Question

So the book I am reading says:

Unlike JAR files, the root-level /META-INF directory is not on the application classpath. You cannot use the ClassLoader to obtain resources in this directory. /WEB-INF/classes/META-INF, however, is on the classpath. You can place any application resources you desire in this directory, and they become accessible through the ClassLoader.

And currently under WEB-INF directory I have a META-INF directory and a file called: test.txt.

How can I read this file using the ClassLoader ?

I have tried this:

URL resource = this.getClass().getClassLoader().getResource("test.txt");
System.out.println(resource);

But this returns null.

I know the file can be read like:

InputStream resourceContent = getServletContext().getResourceAsStream("/WEB-INF/META-INF/test.txt");
System.out.println(resourceContent);

but this is not I want. I want to understand the ClassLoader..

Thanks.

Answer 1

Try using this:

URL resource=this.getClass().getClassLoader().getResource("META-INF/test.txt");

as your /META-INF is in your root path you will have to use META-INF/test.txt to access it.
