How to get resources directory path programmatically

Question

I have the following directory layout           src      main      java    resources      sql  scripts for database    spring  configuration       webapp            Within a ServletContextListener class  I want to access the files under the SQL directory and list them  Basically my problem is with the path  because I know that listing files under a directory in a nutshell is   File folder   new File path   File   listOfFiles   folder listFiles      Maybe I could use the ServletContextEvent Object to try and build a path to resources sql  public void contextInitialized ServletContextEvent event        event getServletContext       getRealPath etc       Does something exist to set that path in a relative  non-hardcoded way  Something like new File  classpath sql    preferably spring if possible  or what should I do with the servletContext to point at resources sql

import org springframework core io ClassPathResource        File folder   new ClassPathResource  sql   getFile    File   listOfFiles   folder listFiles      It is worth noting that this will limit your deployment options  ClassPathResource getFile   only works if the container has exploded  unzipped  your war file

I m assuming the contents of src main resources  is copied to WEB-INF classes  inside your  war at build time  If that is the case you can just do  substituting real values for the classname and the path being loaded    URL sqlScriptUrl   MyServletContextListener class                         getClassLoader   getResource  sql script sql

Finally  this is what I did   private File getFileFromURL         URL url   this getClass   getClassLoader   getResource   sql        File file   null      try           file   new File url toURI           catch  URISyntaxException e            file   new File url getPath           finally           return file                   File folder   getFileFromURL    File   listOfFiles   folder listFiles

Just use com google common io Resources class  Example    URL url   Resources getResource  file name     After that you have methods like   getContent     getFile      getPath   etc
