How do I access a text file from within my war

Question

How do I know what file reference to use to get a file from my WAR.

The structure of the WAR is:

WAR
src
- model
- web

Answer 1

One way to do this comes with a caveat that I'll explain below. You should do something like this:

// In a Servlet
ServletContext sc = getServletContext();
BufferedReader in = 
    new BufferedReader(new FileReader(sc.getRealPath("WebContent/config.txt"));

This assumes that your servlet container is configured to expand war files into their corresponding directory structure.

Answer 2

Check out ServletContext.getResourceAsStream(). Here is an example.

Answer 3

I think just remove WebContent from the path while reading the file and it should help.

Answer 4

The safest way to access this file should be something like this:

InputStream input = getClass().getClassLoader().getResourceAsStream("your/path/enter/here");
