How to get resources directory path programmatically


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?

The Best Answer is


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

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();
