How to get list of file names from a directory?

How to get list of file names from a directory?
Please help

In addition, this:
String filename = files;Should be this:
String filename = files;
That's just because he didn't use the "code" tags, so [ i ] made everything following it become italicized.

  • How to get the target file name from an URL?

    Hi there,
    I am trying to download data from an URL and save the content in a file that have the same name as the file on the server. In some way, what I want to do is pretty similar to what you can do when you do a right click on a link in Internet Explorer (or any other web browser) and choose "save target as".
    If the URL is a direct link to the file (for example: http://java.sun.com/images/e8_java_logo_red.jpg ), I do not have any problem:
    URL url = new URL("http://java.sun.com/images/e8_java_logo_red.jpg");
    System.out.println("Opening connection to " + url + "...");
    // Copy resource to local file                   
    InputStream is = url.openStream();
    FileOutputStream fos=null;
    String fileName = null;
    StringTokenizer st=new StringTokenizer(url.getFile(), "/");
    while (st.hasMoreTokens())
                    fileName=st.nextToken();
    System.out.println("The file name will be: " + fileName);
    File localFile= new File(System.getProperty("user.dir"), fileName);
    fos = new FileOutputStream(localFile);
    try {
        byte[] buf = new byte[1024];
        int i = 0;
        while ((i = is.read(buf)) != -1) {
            fos.write(buf, 0, i);
    } catch (Throwable e) {
        e.printStackTrace();
    } finally {
        if (is != null)
            is.close();
        if (fos != null)
            fos.close();
    }Everything is fine, the file name I get is "e8_java_logo_red.jpg", which is what I expect to get.
    However, if the URL is an indirect link to the file (for example: http://javadl.sun.com/webapps/download/AutoDL?BundleId=37719 , which link to a file named JavaSetup6u18-rv.exe ), the similar code return AutoDL?BundleId=37719 as file name, when I would like to have JavaSetup6u18-rv.exe .
    URL url = new URL("http://javadl.sun.com/webapps/download/AutoDL?BundleId=37719");
    System.out.println("Opening connection to " + url + "...");
    // Copy resource to local file                   
    InputStream is = url.openStream();
    FileOutputStream fos=null;
    String fileName = null;
    StringTokenizer st=new StringTokenizer(url.getFile(), "/");
    while (st.hasMoreTokens())
                    fileName=st.nextToken();
    System.out.println("The file name will be: " + fileName);
    File localFile= new File(System.getProperty("user.dir"), fileName);
    fos = new FileOutputStream(localFile);
    try {
        byte[] buf = new byte[1024];
        int i = 0;
        while ((i = is.read(buf)) != -1) {
            fos.write(buf, 0, i);
    } catch (Throwable e) {
        e.printStackTrace();
    } finally {
        if (is != null)
            is.close();
        if (fos != null)
            fos.close();
    }Do you know how I can do that.

    Thanks for your answer.
    By following your idea, I found out that one of the header ( content-disposition ) can contain the name to be used if the file is downloaded. Here is the full code that allow you to download locally a file on the Internet:
          * Download locally a file from a given URL.
          * @param url - the url.
          * @param destinationFolder - The destination folder.
          * @return the file

         public static final File downloadFile(URL url, File destinationFolder) throws IOException {
              URLConnection urlC = url.openConnection();
              InputStream is = urlC.getInputStream();
              FileOutputStream fos = null;
              String fileName = getFileName(urlC);
              destinationFolder.mkdirs();
              File localFile = new File(destinationFolder, fileName);
              fos = new FileOutputStream(localFile);
              try {
                   byte[] buf = new byte[1024];
                   int i = 0;
                   while ((i = is.read(buf)) != -1) {
                        fos.write(buf, 0, i);
              } finally {
                   if (is != null)
                        is.close();
                   if (fos != null)
                        fos.close();
              return localFile;
          * Returns the file name associated to an url connection.<br />
          * The result is not a path but just a file name.
          * @param urlC - the url connection
          * @return the file name
          * @throws IOException Signals that an I/O exception has occurred.
         private static final String getFileName(URLConnection urlC) throws IOException {
              String fileName = null;
              String contentDisposition = urlC.getHeaderField("content-disposition");
              if (contentDisposition != null) {
                   fileName = extractFileNameFromContentDisposition(contentDisposition);
              // if the file name cannot be extracted from the content-disposition
              // header, using the url.getFilename() method
              if (fileName == null) {
                   StringTokenizer st = new StringTokenizer(urlC.getURL().getFile(), "/");
                   while (st.hasMoreTokens())
                        fileName = st.nextToken();

  • How to get the long file name from an 8.3 name in Windows.

    Because of a legacy string limitation, I have a list of files in 8.3 format. The actual files are saved with long names. How can I get the long name from the short name?
    In JavaScript, I would get a file system object and get the file object from there with the short name. Then it's no problem to get the full name. But I don't see anything in Java that matches that. ???
    Ideas?
    Frank Perry, MSEE

    Here is what I did.
    String displayName = "somefi~1.txt";
    File fO = new File("c:\\"); // I have a more involved path but that's not important here.
    String stPath = fO.getPath() + displayName;
    File fD = new File(stPath); // get the file using the short name.
    File fDc = new File(fD.getCanonicalPath()); // get another file using the cononical name
    String FulldisplayName = fDc.getName(); // get the long name from there.
    It's roundabout but it works. Since getName() on the file read with the short name only returns the name used to get the file, I open it twice. The alternative is to parse the cononical name for the file name but that's clumbsy too.

  • How to get List Item attachments name without write any custom code or any database query?

    Hi,
    How to get List Items attachments name without write any custom code or any database query?

    You can get it from Rest,
    There are 2 options,
    1) create a 'Result Source' which has a search query for that List which has attachments 
     - Use rest query to get the 'Filename' , it will have the attachment file name 
    For example, if the result source id is : 73e6b573-abf8-4407-9e5f-8a85a4a95159 , then the query will be 
    http://[site URL]/_api/search/query?querytext='*'&selectproperties='Title,Path,FileExtension,SecondaryFileExtension,Filename'&sourceid='73e6b573-abf8-4407-9e5f-8a85a4a95159'&startrow=0&rowLimit=100
    You can refine the query, be giving proper 'querytext'
    2) Use the List rest api
    For example if your list guid is :38d524a1-e95c-439f-befd-9ede6ecd242e
    You can get he attachments for 1st item using this 
    http://[Site URL]/_api/lists(guid'38d524a1-e95c-439f-befd-9ede6ecd242e')/items(1)/AttachmentFiles

  • How can I assign image file name from Main() class

    I am trying to create library class which will be accessed and used by different applications (with different image files to be assigned). So, what image file to call should be determined by and in the Main class.
    Here is the Main class
    import org.me.lib.MyJNIWindowClass;
    public class Main {
    public Main() {
    public static void main(String[] args) {
    MyJNIWindowClass mw = new MyJNIWindowClass();
    mw.s = "clock.gif";
    And here is the library class
    package org.me.lib;
    public class MyJNIWindowClass {
    public String s;
    ImageIcon image = new ImageIcon("C:/Documents and Settings/Administrator/Desktop/" + s);
    public MyJNIWindowClass() {
    JLabel jl = new JLabel(image);
    JFrame jf = new JFrame();
    jf.add(jl);
    jf.setVisible(true);
    jf.pack();
    I do understand that when I am making reference from main() method to MyJNIWindowClass() s first initialized to null and that is why clock could not be seen but how can I assign image file name from Main() class for library class without creating reference to Main() from MyJNIWindowClass()? As I said, I want this library class being accessed from different applications (means different Main() classes).
    Thank you.

    Your problem is one of timing. Consider this simple example.
    public class Example {
        public String s;
        private String message = "Hello, " + s;
        public String toString() {
            return message;
        public static void main(String[] args) {
            Example ex = new Example();
            ex.s = "world";
            System.out.println(ex.toString());
    }When this code is executed, the following happens in order:
    1. new Example() is executed, causing an object to constructed. In particular:
    2. field s is given value null (since no value is explicitly assigned.
    3. field message is given value "Hello, null"
    4. Back in method main, field s is now given value "world", but that
    doesn't change message.
    5. Finally, "Hello, null" is output.
    The following fixes the above example:
    public class Example {
        private String message;
        public Example(String name) {
            message = "Hello, " + name;
        public String toString() {
            return message;
        public static void main(String[] args) {
            Example ex = new Example("world");
            System.out.println(ex.toString());
    }

  • How to get the Portal Page name from PLSQL?

    Can anyone tell me how to get the portal page name from my dynamic page using plsql?
    Apparently you can get the page id and work it out from there, but my calls to get the page id are not returning any values anyway.
    My code for attempting to get the page id is below.
    <oracle>
    declare
    v_pageid varchar2(30);
    begin
    v_pageid := wwpro_api_parameters.get_value('_pageid', '/pls/portal30');
    htp.print('Page is '|| v_pageid);
    end;
    </oracle>
    Ideally I'd actually just like to get the page name. Is there a straightforward way to do this?
    Thanks in advance!
    Sarah

    Few clarifications -
    1. wwpro_api_parameters cannot be used to get default portal
    page parameters such as '_pageid', '_dad', '_schema' etc.,
    2. Page information can be obtained through any components which
    are available in that particular page. For example, in case of
    dynamic page, we need to publish it as a portlet and add it to the
    page. This process creates necessary packages in the DB, but we
    will not have access to the portlet methods.
    So, I would prefer creating a simple DB provider & portlet and access
    page title from its show method as follows -
    //Declare local variable l_page_id, l_page_title as varchar2
    select page_id into l_page_id from wwpob_portlet_instance$ where
    portlet_id = p_portlet_record.portlet_id and
    provider_id = p_portlet_record.provider_id;
    select name into l_page_title from wwpob_page$ where id=l_page_id;
    More information on DB provider can be found at
    http://portalstudio.oracle.com/pls/ops/docs/FOLDER/COMMUNITY/PDK/articles/understanding.database.providers.html
    Secondly, usage of wwpro_api_parameters.get_value method is
    incorrect. This method expects two arguments -
    <ul>
    <li><b>p_name : </b> The name of the parameter to be returned.</li>
    <li><b>p_reference_path : </b> An unique identifier for a portlet instance on the current page.</li>
    </ul>
    p_reference_path would be something like 99_SNOOP_PORTLET_76535103 and not some type of path as its name suggests.
    The following code fragment fetches all parameters available
    for a portlet.
    Note : Copy this code into 'show' method of your portlet.
    //Declare l_names, l_values as owa.vc_arr
    * Retreive all of the names of parameters for this portlet
    l_names := wwpro_api_parameters.get_names(
    p_reference_path=>p_portlet_record.reference_path);
    * Retreive all of the values of parameters for this portlet
    l_values := wwpro_api_parameters.get_values(p_names=>l_names,
    p_reference_path=>p_portlet_record.reference_path);
    //Loop through these arrays to get parameter information
    htp.p('<center><table BORDER COLS=2 WIDTH="90%" >');
    htp.p('<tr ALIGN=LEFT VALIGN=TOP>');
    htp.tableData(wwui_api_portlet.portlet_heading('Name',1));
    htp.tableData(wwui_api_portlet.portlet_heading('Value',1));
    htp.tableRowClose;
    if l_names.count = 0 then
    htp.p('<tr ALIGN=LEFT VALIGN=TOP>');
    htp.p('<td COLSPAN="2">'
    ||wwui_api_portlet.portlet_text(
    'No portlet parameters were passed on the URL.',1)
    ||'</td>');
    htp.tableRowClose;
    else
    for i in 1..l_names.count loop
    htp.p('<tr ALIGN=LEFT VALIGN=TOP>');
    htp.tableData(l_names(i));
    htp.tableData(l_values(i));
    htp.tableRowClose;
    end loop;
    end if;
    htp.p('</table></center>');
    Hope it helps...

  • How to get the actual font name from a font file?

    Hi
    I have only the font Path I have to get the font name from that path. Any idea how to get the actual font name?
    Thanks,

    I would ask you these questions:
    Why do you need to do this?  What are you ultimately trying to accomplish?
    Are you really asking about the InDesign SDK?
    Do you really need to get the "name" of a font from an arbitrary file?  Or do you want information about a font installed on the system?  If so, what OS?
    Do you need to be able to handle any font format?
    Which font "name" do you mean?
    What language do you want the name in?
    (1) It's not clear what you're trying to accomplish.  A bit more information about your ultimate goal would be helpful.
    (2) This question is not at all specific to the InDesign SDK.  Are you really trying to do something in the context of an InDesign plug-in?  If so, you probably want to look at IID_IFONTFAMILY and the IFontFamily::GetFamilyName function.
    (3) If you are asking more generally, Windows and Mac both have system API calls to get this information, although those tend to deal with installed system fonts, not with arbitrary font files per se.
    Also, you can parse the name table from a True Type or Open Type font without using any system APIs; as True Type and Open Type are well-documented standards.  I would start by reading these:
    The Naming Table
    Font Names Table
    (4) Although there are other standards, such as Type 1 (PostScript) fonts, and True Type Collection files and other formats, especially on Mac.
    (5) Also, when you start down this road, you will quickly realize that your seemingly simple question is actually ambiguous, and that the answer is kind of complicated, because a font can have many names (a family name, a full font name, a style name, a PostScript name, etc.).
    (6) And not only does a font have multiple names, it can have each of those names in multiple languages and encodings.
    Any clarification would make this a better question.

    Hi,
    There are couple of links already available for this. Just for info see the below details,
    The Output file name could be used from the field value of payload. For this you need to use the UDF DynamicFile name with below code,
    //       Description: Function to create dynamic Filename
    DynamicConfiguration conf = (DynamicConfiguration) container.getTransformationParameters().get(StreamTransformationConstants.DYNAMIC_CONFIGURATION);
    DynamicConfigurationKey key = DynamicConfigurationKey.create("http://sap.com/xi/XI/System/File" , "FileName");
    conf.put(key,a);
    return "";
    DynamicConfiguration conf = (DynamicConfiguration) container.getTransformationParameters().get(StreamTransformationConstants.DYNAMIC_CONFIGURATION);
    DynamicConfigurationKey key = DynamicConfigurationKey.create("http://sap.com/xi/XI/System/File" , "FileName");
    conf.put(key,a);
    return "";
    With this udf map it with the MessageType as
    (File Name field from Payload) > DynamicFileConfiguration>MTReceiver

  • How to create Dynamic Selection List containg file names of a directory?

    Hi,
    I need a Selection List with a Dynamic List of Values containing all file names of a particular directory (can change through the time).
    Basically, I need an Iterator over all file names in a directory, which could be used for Selection List in a JSF form.
    This iterator has nothing to do with a database, but should get the names directly from the file system (java.io.File).
    Can anybody tell me how to create such an iterator/selection list?
    I am working with JDeveloper 10.1.3.2, JSF and Business Services.
    Thank you,
    Igor

    Create a class like this:
    package list;
    import java.io.File;
    public class fileList {
        public fileList() {
        public String[] listFiles(){
        File dir = new File("c:/temp");
        String[] files = dir.list();
        for (int i = 0; i < files.length; i++)  {
                System.out.println(files);
    return files;
    Right click to create a data control from it.
    Then you can drag the return value of the listFiles method to a page and drop as a table for example.
    Also note that the Content Repository data control in 10.1.3.2 has the file system as a possible data source.

    connection pool ? Is it possible to know the name of related pool , if I know
    the name of datasource?
    Thx

    hi
    there are 2 ways:
    url must be: jdbc:weblogic:pool[:connectionPoolID]
    or
    jdbc:weblogic:jts[:connectionPoolID] (if you want to use jts with your JDBC connection.)
    see http://e-docs.bea.com/wls/docs60//javadocs/weblogic/jdbc/pool/Driver.html
    However, I think it is safer to configure and use DataSource to get connection.

    Dear Damorgan,
         >>your version number to three decimal places
         My Oracle DB Version i have already stated in my previous post is 10.2.0.1.0
    Actually my problem is to get the sql files name we run in sqlplus enviornment with @ symbol. like
    i have created one sql file in c drive as
    "C:\Createtable.sql"
    afterwords i have connected to sqlplus as
    sql> conn scott/tiger
    sql>@c:\createtable.sql
    Now i want some query to get the name of the file which is run.
    In actual my problem is as
    i have suppose 10 or more SQL files in some folder ( sql1.sql, sql2.sql, sql3.sql ....).
    i created one file to call all the 10 sql files (main.sql)
    i have also one track_table which will keep track that which sql file is runned.
    I want some automated script which will insert the record in that track_table....... for that i need the name of sql file which is runned.
    Hope this will help you.
    Thanks & Regards
