Writing a file to the server using an applet...?

Hi,
I've been searching the web now for almost a day trying to find some help in how to do this... The biggest problem is that I'm kind of a newbie (not a total beginner, but this is the first time I've ventured into applet creation)
What I'm trying to do is writing a simple web-page updater... i.e. This is what it should be able to do:
1) Read HTML page and parse it so that I can change the important parts (the info on the page, not the actual HTML code) - DONE
2) Present the information and let the user change it as (s)he sees fit - DONE
3) generate the new HTML and write it back as a file on the server (replacing the old one) -- PROBLEM -- :)
I think (!?) that I should be able to do this using the HttpURLConnection() POST method in addition to a PHP script on the server moving the file around once it's been uploaded. I don't, however, have a clue as to what the code should look like to accomplish something like this...(as I've never used it before, and can't seem to find sample code that would be even close to what I'm trying to do)
How can this be done? Also, is there a simpler way of doing this?
Thanks for taking the time to read that :)
-NRGizeR

as I said, I will gladly take suggestions :)
again, I'm new to all of this and I don't really know what things in java (or any of the script languages for that matter) can or cannot do...
Even if there is a better way, I would still know if this is solvable tho (I just want to get my head straight after banging it against this wall for the past few days) :), but as I said, any suggestions would be appreciated...

    My problem is this, How can a client open a files from the server.
    all the html, pdf files are stored in the server's directory like C:\audit\filename.
    There is a folder on the server's C directory which contains all the html , pdf files.

    That's doing it the hard way. Why not use HTTP or FTP?

  • Batch rename files on the server?

    Can someone explain how to batch rename files on the server ?
    I have 1000 rows each containing these fields
    id (unique key)
    productCode
    filename1
    filename2
    For every row I need to rename the following fields:
    Rename [filename1] to [productCode]_[id]_1
    Rename [filename2] to [productCode]_[id]_2
    also I need to rename the actual file on the server using the above scheme
    Can someone show me the way ? I'm a little rusty with ColdFusion

    So far I've got everything working apart from CFFILE which works only if it finds a corresponding jpeg file on the server. In other words it works perfectly until row 20 of the database because the filename contained in the field doesn't have a matching jpeg file on the server, so CFFILE fails like this...
    Attribute validation error for tag CFFILE.
    The value of the attribute source, which is currently C:\images\DSCN1293.JPG, is invalid.
    The error occurred in C:\Inetpub\wwwroot\link\htdocs\old_apps\psp\updater.cfm: line 63
    61 :                    action = "rename"
    62 :                    source = #my_source1#
    63 :                    destination = #my_destination1#>
    is there a way to carry on looping through the remaining rows and ignore the above fail ?

  • Writing from a BLOB to a FIle on the Server

    I need to be able to save the data from a BLOB column to an external file on the server, preferably in a temporary directory. Afterwards I will add a header to the file and send to the web client. I believe I know how to add the header. However, everything I have read in DBMS_LOB or UTIL_FILE describes saving a BFILE or CLOB to a BLOB, but not the reverse. Can you save from a BLOB to an external file on the server? The processing must be done on the Server.
    I have been able to select TEXT from a VARCHAR column and save to a file on the server but unable to select a BLOB and save to the file.
    Thank you for your help,

    UTL_FILE would be the correct thing to use, but I seem to recall that it didn't work for binary files. It apparently adds CR LF data into the files when written. I am not sure if this has changed recently or not. You might try posting in the database or PL/SQL forum about UTL_FILE.

  • Access denied error while writing a file to the file system - myfileupload.saveas() throws system.unauthorizedexception

    hi,
    as part of my requirement , i have to perform read and  write  operations of  few files [ using the file upload control in my custom visual web part] and on submit button click.
    but while writing these files - with the help of  fileupload control - and when i use  myfileupload.saveas(mylocation);
    - i am saving these files into my D:\ drive of my server , where i am executing my code -, am getting access denied error.
    it throws system.unauthorizedexception.
    i have given full control on that folder where i was trying to store my attached files. and also  after following asp.net forums,
    i have added  iusr group added and performed all those steps such that, the file is saved in my D:\ drive.
    but unfortunately  that didnt happen.
    also
    a) i am trying the code with runwithelevatedprivileges(delegate() )  code
    b) shared the drive within the  d :drive where i want o save the files.
    c) given the full privieleges for the app pool identity- in my case , its
    network service.
    the  other strange thing is that, the same code works perfectly in  other machine, where the same sp, vs 2012  etc were installed .
    would like to know, any other changes/ steps i need to make it on this  server, where i am getting the  error.
    help is  appreciated!

    Hi Friends,
    I have gone through scores of examples and i am failing to understand the right thing to be done to copy a file from one directory to another. Here is my class...So let's see... C:\GetMe1 is a directory on your machine, right? And this is what you are doing with that directory:
    public static void copyFiles(File src, File dest) throws IOException
    // dest is a 'File' object but represents the C:\GetMe1 directory, right?
    fout = new FileOutputStream (dest);If it's a directory, where in your code are you appending the source file name to the path, before trying to open an output stream on it? You're not.
    BTW, this is awful:
    catch (IOException e)
    IOException wrapper = new IOException("copyFiles: Unable to copy file: " +
    src.getAbsolutePath() + "to" + dest.getAbsolutePath()+".");
    wrapper.initCause(e);
    wrapper.setStackTrace(e.getStackTrace());
    throw wrapper;
    }1) You're hiding the original IOException and replacing it with your own? For what good purpose?
    2) Even if you had a good reason to do that, this would be simpler and better:
    throw new IOException("your custom message goes here", e);
    rather than explicitly invokign initCause and setStackTrace. Yuck!

  • Socket blocking on read operation while uploading zip file to the server

    I am trying to upload a zip file to the server
    Client thread creates the zip file ( of the modified files) and it even completes writing the data to the socket stream.
    Now if the server thread tries to read the same data from the stream, it blocks on read operation.
    While downloding the zip file from the server works fine.

  • Opening Output Stream to a file on the server from Applet

    Hi,
    I am trying to write a little applet which parses a file found on the server , lets the user select some Strings then write the selected Strings to a different file on the server. I use the following code:
    String fileName = new String("LineUp");
    URL docBase = null;
    URLConnection conn = null;
    try {
    docBase = new URL(ApppletName.codeBase, fileName);
    } catch (java.net.MalformedURLException e) {
    System.out.println("Couldn't create image: "
    + "badly specified URL");
    try {
    conn = docBase.openConnection();
    } catch(IOException e) {System.out.println(e);}
    String playerString;
    try {
    conn.setAllowUserInteraction(true);
    conn.setDoOutput(true);
    conn.connect();
    PrintWriter out = new PrintWriter(
    conn.getOutputStream());
    etc..
    The problem I am having is that the getOutputStream routine for the connection object does nothing other than throw an exception (I've stepped through the code and that is all the routine actually does). The connection is actually made but no output stream can be created. I have looked at the Java Tutorial (as I am fairly new to Java) and found a spot where they tell you how to write to a file on the server, which is the example I have followed. Any suggestions? What am I missing?

    Yes, that's what I thought. It talks about writing to a URL, and you have interpreted "URL" as if it meant "file". A URL is a "Uniform Resource Locator", which is a string that identifies a "resource" on the server. Often that corresponds to a file on the server, but not always. It could be a page that is dynamically generated by a script on the server.
    Look again at that page and you will see these words: "At the other end, a cgi-bin script (usually) on the server receives the data, processes it, and then sends you a response, usually in the form of a new HTML page." What that means is, you can't just upload a file to a URL unless you have programmed the server to deal with that upload. That's part of the basic design of the HTTP protocol.
    So, unfortunately, you can't do what you want all that easily. You would have to provide some programming at the server to handle the file upload for you. In Java that means writing a servlet and getting the web server to have that servlet handle all requests to a particular URL. I suspect you don't want to get into that just yet. But if you do, any decent book on Java servlets should have an example of how to upload files like this.

    HELP!!!! I've searched other threads and to no avail I'm publishing so no direct ftp going on. the only thing I changed in business catalyst was the module stylesheet in order to style the blog. I've tried uploading and replacing all files nothing seems to work. the site is here:

  • How to download a text file from the server

    hi everyone,
    can anyone tell me how to download and read a text file from the server and saved in into resource folder.
    with regards
    pallavi

    its really easy
    To read from server, use something like:
    HttpConnection connector = null;
    InputStream inp_stream = null;
    OutputStream out_stream = null;
    void CloseConnection()
         if(inp_stream!=null)inp_stream.close();
         inp_stream=null;
         if(out_stream!=null)out_stream.close();
         out_stream=null;
         connector.close();
         connector = null;
    public void getResponse(String URL,String params)
      try
         if(connector==null)connector = (HttpConnection)Connector.open(URL);//URL of your text file / php script
         connector.setRequestMethod(HttpConnection.POST);
         connector.setRequestProperty("User-Agent","Profile/MIDP-2.0 Configuration/CLDC-1.1");
         connector.setRequestProperty("content-type", "application/x-www-form-urlencoded");
         //connector.setRequestProperty("charset","windows-1251");
         //*** If you need to send ("arg1=value&arg2=value") arguments to script use this:
         out_stream = connector.openOutputStream();
         byte postmsg[] = params.getBytes();
         out_stream.write(postmsg);
         int rc = connector.getResponseCode();//in any case here connection will be opened & closed
         if (rc != HttpConnection.HTTP_OK)
              CloseConnection();
              throw new IOException("HTTP response code: " + rc);
         inp_stream = connector.openInputStream();
         int pack_len = inp_stream.available();
         byte answ[]=new byte[pack_len];
         inp_stream.read(answ);
         CloseConnection();
         ProcAnswer(answ);//process received data
      catch(Exception ex)
         System.err.println("ERROR IN getResponse(): "+ex);
    } And you can read from resource file like
    public void loadFile(String filename)
        DataInputStream dis = new DataInputStream(getClass().getResourceAsStream("/"+filename));
        String str="";
        try
             while (true)
                ch = dis.read();//read character
                if(ch=='\r')continue;//if file made in windows
                if(ch=='\n' || ch==-1)//end of line or end of file
                    if(str.length()==0)continue;//if empty line
                    //do some thing with "str"
                    if(ch==-1)break;//it was last line
                    str="";//next line
                    continue;
                 str+=(char)ch;
           dis.close();
       catch (Exception e)
           System.err.println("ERROR in loadFile() " + e);
    }Welcome! =)
