来自src / main / resources / somefolder的JSF应用程序列表文件

Question

I'm trying to get a list of files from a folder in the src/main/resources directory of my webapp. Does anyone have a solution ? So, one problem is, that I have only the glassfish.jar in my classpath. I don't find an entrypoint from where I can start. It's a maven project.

The solution so far : which works, but doesn't satisfy me, because of the absolute path.

org.apache.commons.io.FileUtils has to be included.

public Collection<File> queryResourceFileCollectionByDirectoryMember(Class clazz, String resourcePathToMember, String[] extensions) {
    logger.info("------- FileTools : queryResourceFileCollectionByDirectoryMember");

    try {
        //String[] extensions = {"xml"};
        URL resourceURL = clazz.getResource(resourcePathToMember);//"/fields/testOITM.xml" <- one XML file in the /src/main/resources/fields/ folder to get the absolutepath which after deployment is WEB-INF/classes/fields
        String resourcePath = resourceURL.getPath();

        //Remove the leading slash
        String resourcePathWithoutFirstChar = resourcePath.substring(1);
        logger.log(Level.INFO, "------- FileTools : queryResourceFileCollectionByDirectoryMember: resourcePath :{0} :", resourcePathWithoutFirstChar);
        File resourceFileToGetDirectory = new File(resourcePathWithoutFirstChar);
        String resourceDirectoryPath = resourceFileToGetDirectory.getParent() + File.separator; //"c:/Users/xuser/Documents/NetBeansProjects/BOneBApp/target/classes/"
        File resourceDirectory = new File(resourceDirectoryPath);
        Collection<File> files = FileUtils.listFiles(resourceDirectory, extensions, true);
        return files;
    } catch (Exception e) {
        logger.log(Level.SEVERE, "******* FileTools : queryResourceFileCollectionByDirectoryMember : {0}", e.getMessage());
        return null;
    }
}

The clazz can be any class of the webapp.
