Now with Java EE 7 you can find the resource more easily with

InputStream resource = getServletContext().getResourceAsStream("/WEB-INF/my.json");

There s a couple ways of doing this   As long as the WAR file is expanded  a set of files instead of one  war file   you can use this API   ServletContext context   getContext    String fullPath   context getRealPath   WEB-INF test foo txt      http   tomcat apache org tomcat-5 5-doc servletapi javax servlet ServletContext html getRealPath java lang String   That will get you the full system path to the resource you are looking for   However  that won t work if the Servlet Container never expands the WAR file  like Tomcat    What will work is using the ServletContext s getResource methods   ServletContext context   getContext    URL resourceUrl   context getResource   WEB-INF test foo txt      or alternatively if you just want the input stream   InputStream resourceContent   context getResourceAsStream   WEB-INF test foo txt      http   tomcat apache org tomcat-5 5-doc servletapi javax servlet ServletContext html getResource java lang String   The latter approach will work no matter what Servlet Container you use and where the application is installed   The former approach will only work if the WAR file is unzipped before deployment   EDIT  The getContext   method is obviously something you would have to implement   JSP pages make it available as the context field   In a servlet you get it from your ServletConfig which is passed into the servlet s init   method   If you store it at that time  you can get your ServletContext any time you want after that
