JSAGA

The code below throws various exceptions - differ from run to run. What is strange, changing the call createFile to the one with Flags.NONE works fine:

File f = FileFactory.createFile(session, URLFactory.createURL(dir.getURL().toString() + fileName), Flags.NONE.getValue());

Here is the original code:

public class Ssh {

    public static void main(String[] args) throws Exception {
        URL url = URLFactory.createURL("sftp://192.168.154.102");
        Session session = SessionFactory.createSession(false);
        Context ctx = ContextFactory.createContext("UserPass");
        ctx.setAttribute(Context.USERID, "root");
        ctx.setAttribute(Context.USERPASS, "***");
        session.addContext(ctx);
        NSDirectory dir = NSFactory.createNSDirectory(session, url);
        List <URL> dirContent = dir.list();
        dir.close();

        for (URL dirEntry: dirContent) {
             if (dir.isEntry(dirEntry)) {
                 String fileName = dirEntry.getPath();
                 File f = FileFactory.createFile(session, URLFactory.createURL(dir.getURL().toString() + fileName));
                 long size = f.getSize();
                 long date = f.getMTime();
                 boolean readPermisssion = f.permissionsCheck("*", Permission.READ.getValue());
                 boolean writePermission = f.permissionsCheck("*", Permission.WRITE.getValue());
                 boolean executePermission = f.permissionsCheck("*", Permission.EXEC.getValue());
                 f.close();

                 System.out.println(
                         fileName + " " +
                         (readPermisssion ? "r" : "-") + (writePermission ? "w" : "-") + (executePermission ? "x" : "-") + " " + 
                         (date != 0l ? new SimpleDateFormat("dd-MMM-yyyy HH:mm").format(new Date(date)) : "?") + " " 
                         + (size != 0l ? "" + size + "B": "?")
                         );
             }
        }
    }
}
