Getting file list

i'm having some problems getting the list of files into a vector, all the images are .jpg stored in a directory called ads under the classes directory, where all the .class files are stored. here is what i have so far:
    File directory = new File("/ads");
    File[] ads = directory.listFiles();
    if(ads!=null) {
         for(int i = 0; i < ads.length; i++) {
              System.out.println("Files are: " + ads);
else {
     System.out.println("Empty directory");
i have images in the ads directory but i always prints out empty directory, i am using sdk 1.4.

In Windows, preceeding the directory name with a "/" means go to the root directory. Say you are on the "C" drive it would look for a directory named "C:/ads". Not sure how it works on Unix.
File directory = new File("ads");
This will look for a directory "ads" in the current directory.

  • Web Matrix FTP Remote Connection Error - "Connection Error - Failure to get file list from server. An entry with the same key already exists."

    Does anyone have experience with this issue when connecting to a Linux FTP Web Server running a FTP Site?
    "Connection Error - Failure to get file list from server. An entry with the same key already exists."
    I cannot access the root directory of the ftp file server using Web Matrix 3. The site is .php based, and
    is accessible when connecting with FileZilla or Remote Connecting via FTP with Visual Studio.
    All sites have been deleted from Web Matrix, the user Application Data has been cleared and Web Matrix has been reinstalled.
    Issue Persists....
    Thanks in advance,

    Turns out that the program leaves metadata in your app data folder that is not removed upon uninstallation of the software.
    This is incorporated to communicate with a file that uploaded into the ftp directory when publishing pages.

  • Java does not get file list from shared folder in another server.

    I'm using java,
    Command below does not get file list.
    File file = new File("\\\\\\SapMII");
    File[] files = file.listFiles();
    SapMII folder is Everyone full Control permission.
    How can i solve this problem?

    Could you please post replies in a more helpful way? Just informing me that it was an NPE doesn't really tell me anything. Post the stacktrace (Exception#printStackTrace()). And the listFile() methods API has this to say:
    Returns null if this abstract pathname does not denote a directory, or if an I/O error occurs.I'm able to run this sample code easily:
    public class TestFileList {
         public static void main(String[] args) {
              File file = new File("\\\\\\shared");
              File [] files = file.listFiles();
              for(File currentFile: files )

  • FTP Get File List Action Block, It's double listing files!  ver 11.5

    Hi guys.. I have a good one!   I have an FTP Get File List action block in my BLS transaction.  Occasionally, it double lists the files in its output.   For testing I put a repeater with a logevent output where I log the filename, date, and size.  Heres what I saw for my action block output.
    2009-02-13 00:38:00,963  [UserEvent] : File Name: DMM_Export_0010056.txt, File Date 2009-02-13T00:36:00, File Size 339
    2009-02-13 00:38:00,963  [UserEvent] : File Name: DMM_Export_0010056.txt, File Date 2009-02-13T00:36:00, File Size 339
    This is xMII  version 11.5.6 b73  with java 1.4.2_07
    I have a workaround by putting in a distinct action block, after the filelist, but anybody have an idea why this might happen?   My theory is that something might be occuring if the file is being written to while we try to process it, but not sure. 
    I've been building BLS parsers since 2003, (Remember those fun times with Jeremy?)   I've never seen this happen.

    My example is a sample log file before the distinct action.  The general log shows nothing other than the subsequent transaction errors I get as a result of running the same error twice (Tcode return from BAPI calls etc)
    Here is something else interesting..  my userlog file is acting funny, like its trying to write on top of itself.  could it be the transaction is actually running twice or parts of it? 
    For example look at the following log entries
    This is how my log file entry for a production confirmation should look
    2009-02-13 00:38:06,854 [LHScheduler-Int10_NestingWOProdConf] INFO   UserLog - [UserEvent] :
    However sometimes... its looking like this...
    2009-02-13 2009-02-13 00:38:11,854 [LHScheduler-Int10_NestingWOProdConf] INFO   UserLog - [UserEvent] :
    Like it started writing to the log, then started again.
    The problem we are having is that we have JCO calls to SAP in this transaction that does goods movement, we get locking / block errors back from our  saying that we (our sap account) is already updating the information.   Sometimes the information would be posted twice!  You can see how this has become a HUGE issue posting data to a LIVE system twice.
    This is happening on 2 xMII servers.

  • Why I just get file list?

    hi,I compiled j2ee tutorial example hello3,I deploy it by asant and config it by deploytool,when connect from IE(http://localhost:8080/hello3),I just get a file list,when I click the greeting.jsp,I get the web content displayed,everything likes fine.I just want know why I got file list(I got same situation with other example).
    thanks advance!

    You can make a screenshot picture of each page of the list right from Preview, via
    File menu>Grab>Selection
    drag over the list and let go.
    The resulting tiff file snapshot on the desktop (and itself now open in Preview) is readable and printable, but since it is an image, it is not editable or copyable as text.
    If you really need editable text , and if you also have an OCR program that might have come free with a scanner, then.. (ugh..)
    (Yes, it's not only a kludge, but a really BAD one! There's got to be a better way.. )

  • Get file list from URL/web directory

    Hey guys,
    I have created a script for After Effects that can download multiple images from URLs that are given in an array. Now ideally what I want, is to get all the filenames of the files in a certain browsable web directory to be put in an array.
    Unfortunately, I can't seem to figure out how to do this. Does someone have the knowledge here to help me out?
    Thanks in advance,

    This is more difficult to do than it seems. Since the files are on a remote web server, you need to find some way to get the server to divulge its local file structure, which is not something most servers will do. The absolute best way is to have control over the web server and run some server-side code (PHP, node.js, whatever) to generate the file list on the server side and then fetch it with your client/extension/script. Other than that it's almost impossible to get a 3rd party server to divulge its file structure as far as I know, mainly for security reasons. So the #1 question is: do you have control over the server/website that you're trying to fetch from or not?

  • FTP_COMMAND in order to get files list at FTP address

    Hi all.
    I want to get a list of files exist at a specific FTP address.
    For that I'm using FTP_CONNECT (OK) and after I want to execute FTP_COMMAND with parameter command = 'ls' in order to recievce the files list in output table data[].
    I keep on getting an exception 3 (data_error).
    Anyone can help please ?

    I know by experience the ABAP programmers learn most based on examples.
    In every SAP system you have the following FTP example programs, analyze the source code and check how function modules like FTP_CONNECT and FTP_COMMAND work :
    RSFTP002                         Execute FTP Command
    RSFTP003                         FTP put / get Test
    RSFTP004                         FTP Copy
