this.getClass().getClassLoader().getResourceAsStream always returning null

问题

While reading a file in a web application with

this.getClass().getClassLoader().getResourceAsStream(../abc.txt)

is always returning null. Can anyone please provide details where should I put abc.txt in order to read. And any article on getResourceAsStream will be helpful. I have searched a lot but did not get any relevant information.

Please provide your valuable suggestions. Thanks.

If your abc.txt is in classpath and in different package like com/test/oops/testpaper/abc.txt.

Then read it like below.

InputStream io=this.getClass().getClassLoader().getResourceAsStream("com/test/oops/testpaper/abc.txt");

For detail please go through java doc.
