I think you can put your .txt file in your classpath,
in a folder or in a jar.
In some package,
e.g

in com/xxx/

Then you can use the code:
public class XXXServlet extends HttpServlet{
      ....
     void mymethod(){
          s=new BufferedReader(new InputStreamReader(

XXXServlet.class.getResourceAsStream("/com/xxx/yourtxt.txt")));
                   // here "/" means the root of your classpath,
                   //you can get a platform independent path now ;-)
     }
}

I have some text files I'd like to put on my web server (preferably in the

read and parse from some of my servlets. Does anyone have a code snippet
from doing this from within, say, my servlet's init() method? The parsing
bit I've already done; what I'm having trouble with is figuring out how to
get absolute paths that I can use in my Buffered reader.

Here's what I've got so far...

            ServletContext context = getServletContext();
            String realContextPath = context.getRealPath("/");
            s = new Scanner(new BufferedReader(new FileReader(
"mapping1.txt")));

For some reason calling getRealPath("/") above returns something unusual;
instead of "mypath\web" I get "mypath\build\web". Not sure where that
"build" bit is coming from or if it matters. Probably the result of my
compilation, with mapping1.txt copied in along with the rest of the web a=

pp?

Also, what happens if I deploy my final product as a jar file? Can I sti=

read files from WEB-INF, or another directory within the web server, just
like if I had deployed an uncompressed set of folders?
