This is the simplest wat to get the File object to which a certain URL object is pointing at:
File file=new File(url.toURI());
Now, for your concrete questions:
•finding all resources in the META-INF "directory":
You can indeed get the File object pointing to this URL
Enumeration<URL> en=getClass().getClassLoader().getResources("META-INF");
if (en.hasMoreElements()) {
URL metaInf=en.nextElement();
File fileMetaInf=new File(metaInf.toURI());
File[] files=fileMetaInf.listFiles();
//or
String[] filenames=fileMetaInf.list();
}
•all resources named bla.xml (recursivly)
In this case, you'll have to do some custom code. Here is a dummy example:
final List<File> foundFiles=new ArrayList<File>();
FileFilter customFilter=new FileFilter() {
@Override
public boolean accept(File pathname) {
if(pathname.isDirectory()) {
pathname.listFiles(this);
}
if(pathname.getName().endsWith("bla.xml")) {
foundFiles.add(pathname);
return true;
}
return false;
}
};
//rootFolder here represents a File Object pointing the root forlder of your search
rootFolder.listFiles(customFilter);
When the code is run, you'll get all the found ocurrences at the foundFiles List.
********************************************
example:
private static void init() {
URL url = NTGLoggerFactory.class.getClassLoader().getResource(FILE_NAME);
PropertyConfigurator.configure(url);
initialized = true;
}
File file=new File(url.toURI());
