Access files located in root of WAR file from ServletContextListener

Question

I have a .war file. And I need access to file located inside ROOT_OF_WAR/someFolder/myfile.txt

How I can access to it using ServletContextListener?

Does ContextClassLoader#getResourceAsStream(resourceName) point to root of web-app (i.e. root of.war file)?

Or I need to access it using ServletContextEvent#getServletContext().getResourceAsStream("someFolder/myfile.txt"); ?

This link http://stackoverflow.com/questions/12883861/how-to-access-a-file-under-web-inf-folder-in-java-class has a lot of good information. — Suketu Bhuta, Jan 09 '15 at 19:44

ServletContext context = servletContextEvent.getServletContext();    
File file = new File(context.getRealPath("/someFolder/myFile.txt"));

That is all you need. See here.

`getServletContext()` method is undefined for type `ServletContextListener`. I can get it only from `ServletContextEvent#getServletContext()` - but it will still work? I have some concerns about it. – WelcomeTo Sep 21 '12 at 13:17

I am using: new File(context.getRealPath("/WEB-INF/jdbc/hibernate.cfg.xml")) to get the hibernate cfg file. And it works perfectly. It is also in the ServletContextListener – Paulius Matulionis Sep 21 '12 at 13:22
