Applet access local file

I have an applet that access local files and directory.
I have create the applet policy file.
When viewing with appletviewer, we can type:
appletviewer -J-Djava.security.policy=applet.policy MainApplet.html
However, when I want to embed the applet in a html, how can the policy file be included?
Thx a lot.

how can the policy file be included?Applets use the java.policy wich is located in the jre/lib/security
(C:\Program Files\Java\jre1.5.0_04\lib\security)
There is a java.security where you can add or change the java.policy files to be
used
policy.url.1=file:${java.home}/lib/security/java.policy
After changing these files make sure the jre loads again, close all browsers
and open the page.

  • Applet accessing local files under Vista

    I have a signed applet that accesses files on the client machine. This applet is not able to open files when running under Windows Vista (I get an "Access denied" message). I found that in C++ there is a function called GetTempPath, which returns a path to a directory where and OCX control can access files. So here is my question:
    Is there some Java function that will return the path to the directory mentioned above?
    Thanks for your help.

    Sorry, DrClap, but...
    Post 1: "I have a signed applet that accesses files on the client machine. This applet is not able to open files when running under Windows Vista (I get an "Access denied" message)." While he mentions temp files/dirs, that is not, IMO the issue, because...
    Post 6: "Under these OSs [XP, 2000], my applet uses a directory called c:\program files\mydir. This applet is not able to access files in the same directory under Windows Vista, access is denied in this case." The specified directory is not a "temp" dir as typically returned by the system parameters that I've ever seen, so I'm assuming he's using this explicitly. In which case, access is denied writing to it. In which case, it appears to be a signed applet permission issue.
    While the java.io.tmpDir system param may be giving an issue to, that doesn't seem to be the key point in what I'm reading. Otherwise it's not written entirely clearly.

  • When i drag and drop an image on my site. it gives the following error. "Unable to access local files due to browser security settings. To overcome this, follo"

    I am using the firefox version 17 and when i drag and drop an image on my website. It gives me the following error.
    Unable to access local files due to browser security settings. To overcome this, follow these steps: (1) Enter "about:config" in the URL field; (2) Right click and select New->Boolean; (3) Enter "signed.applets.codebase_principal_support" (without the quotes) as a new preference name; (4) Click OK and try loading the file again. Or go to the homepage for a link to the tutorial on how to do it.
    I have completed the above steps and it is still showing the same error message. Any help would be highly appreciated.
    Thanks.

    Thanks kumars ,
    I have a specific drag and drop area on our website. This works fine for all earlier releases of Firefox after these security settings
    "(1) Enter "about:config" in the URL field; (2) Right click and select New->Boolean; (3) Enter "signed.applets.codebase_principal_support" (without the quotes) as a new preference name; (4) Click OK and try loading the file again."
    Bust these settings not work for me in Firefox 17.
    Yes the drag and drop functionality is java script based and i am not using any script blocker addons.

  • How Can I Get A Flash Movie to Access Local Files

    I have a customer that has created a Flash movie to run off a CD.  The movie is basically a set of menus with links to access local files in the same directory as the movie.  i.e. Main folder (to be root of CD) has the movie, a Documents folder with PDFs, a Movie folder with wmv and mov files, etc.
    The problem arrises when you click on a link to a file, a web browser is launched, and the browser tries to display the target file.  The movie was designed on a Windows system, and, mostly it works in a Windows environment, however, the links totally crap out on a Mac because the URLs are pc centric.
    He is a rookie flash programmer so I am trying to help him set up proper links to the files, so that the files will (hopefully) launch the proper local app and not a web browers.  i.e. if the link points to a PDF, the Adobe Reader is launched; if the link is to a mov file, then QuickTime is launched....
    Is there a way to do this?  All the tutorials I have found all seem to expect the flash movie to be running on a web server, and as such do not work when running the movie off a CD.
    Any help or suggestions would be grealy appreciated.
    A response ASAP would also be greatly appreciated as the customer needs to deliver 200 CDs of the project for a presentation tomorrow morning - I have to create the CDs...
    TIA

    Hi there,
    Maybe you would want to use swfObject, i've been using it for
    a long time now.

  • Reading files from local hard disk - Access Local Files Only

    Hi All,
    I have a local flash file published as 'Access Local Files Only', to allow me to read from local filesystem.
    What methods or classes can I use to read text and other files from the user's harddisk.
    This is the first time I am trying to do something like this, all help is grealy appreciated.
    Thanks
    Andy

    Hi, thanks for the responses
    I did some searching and found that the urlloader class is the right one for the job.
    'Access Local Files Only' option is provided for this very purpose I believe.
    If anyone has done something like this and have some sample code it would be awesome
    Cheers

  • Accessing local files in Safari for Windows

    I am trying to access local files, such as .doc and .pdf files. I have tried
    file://server/dir/dir/file.pdf, and various numbers of slashes, but all result in Failed to open page messages.
    Any ideas? IE can do this, Firefox won't (easily).

    If you wish to view "local" files in any browser just drag the file icon to an empty browser window.
    The "file:///blah/blah" stuff and a URL has ended for security issues.

  • Can I access local files?

    I am writing an application using Adobe Air that will have to utilize and store media files locally on a user's computer.  My marketing team now believes that a downloadable application that will be installed on a user's computer will be a dealbreaker for some users due to the fear of a virus, so now they are suggesting that we will have better sales numbers if people just need to log into a website to use the application.  No problem, Air applications can be embedded into a website.  But can an Air application embedded in a browser still store and manipulate files on a user's computer?  Storing media files for a large number of individuals can become cost prohibitive, so rather than store them online, we would like to create a folder on a user's system to organize their files.  Is this possible with a web-embedded Air application?
    Thanks.

    AIR applications are always installed on the user's computer. You cannot run an AIR application on a website. On a web page, you can include a link to download or install an AIR application.
    AIR applications can access local files.
    Flash Player applications can also access local files, but the user first grants permission. For example, see the FileReference.load() and FileReference.save() methods (added in Flash Player 10):

  • How the applet can access local file system?

    1. I want to plugin the applet into the JSP. That applet should access the local file system. How to enable this programmatically.
    2. Is it is possible to embed a frame inside the JSP. If so how?
    Thanks in advance..
    K G Vinoth

    1: If you want the applet to access the client's local file system you'll have to sign the applet. There is a tutorial some where on the java.sun.com that explains how to sign an applet.
    2: No you;ll need to use an applet to display swing or awt components on the client browser.

  • Can applet access a file on its server????????

    i have ana applet that needs to access a file on the server from which it was downloaded. it worked when i changed the security permissions at IE to allow an UNSIGNED applet to access ALL FILES.
    now this is a problem for me. is there a way i can move around this or maybe signing the applet would work, though i don't know how....
    help would be highly appreciated.
    sam

    File access (read) on the server should be possible as long as you are accessing the file and applet using HTTP. IE will not see this as an access violation. Sending updates to the file is a different story. You either need to create a servlet running on the server to accept the updated file or access the server via FTP. Browsers do not interpret direct file access as coming from the same server even if it does. I think this has something to do with the fact that you are using the local file system to access the server even if it is on a networked drive or location.
    And yes, signing the applet would resolve the issue.

  • Is it possible to access local files with MIDP?

    Hello everyone,
    I am developing a mobile application using Sun One Studio 4 ME, with MIDP 2.0.
    I am preparing a record store as input data for my application. "Preparing" means: I try to convert a local text file present on my PC into a record store.
    The problem I have is that I cannot find a way in MIDP to allow me to access the local file. It seems to me that MIDP only allows data access over the Web. Am I correct?
    Many thanks in advance for any help or suggestion you could provide.

    Did you save the messages in a Personal Folder files (PST) or as individual messages on disk? The PST and MSG file formats are proprietary and might not be accessible outside of Outlook.
    If you want to move those messages to a different email program, assuming you have permission to do so, one way is to upload them to an IMAP account (Gmail allows you to connect Outlook as an IMAP client). However, that's pretty complicated, so I suggest researching it on the web, checking at least a few sites to make sure you know all the steps.

  • Problems Accessing Local Files

    Hi,
    I'm sure this has been discussed before, but I'm havign problems accessing a file on the target machine's local filesystem. I've signed all my jars and added the all-permissions tag to the jnlp file. However, my code:
    ClassLoader cl = getClass().getClassLoader();
    InputStream is = cl.getResourceAsStream("c:/resources/testsuite.xml");
    fails to find the file "testsuite.xml".
    Is this a classpath issue? I've tried to add c:/resources to the class path but with no luck.
    any help would be much appreciated
    Thanks

    Try "file://c:/resources/testsuite.xml" instead. I
    believe you are suppose to be passing in a valid URL
    and what you passed in wasn't.That's wrong. Resource name should be just a path. It could be a full path started from "/" or just a relative path from given class (here better to use this.class.getResourceAsStream() method).
    Better yet, since you are giving full security access
    to the user's local machine you don't really need to
    rely on the class loader at all. It's just a normal
    file, so you could create your File object and read it
    in the way you do normally. I would suggest to do not rely on File object at all because it can only be dealing with local file system and thats can't be changed in future.

  • How can an applet access a file ??

    I have written an applet in Netbeans and it is working ok.. Now I need to embed this applet in an html file. I have used the following code for doing so :
    <Html>

    </Body>
    </Html>Now when i run the html file.. the applet does not run. It gives an error called Applet notinited.

    Edited by: sauvikc on Jul 25, 2008 7:33 AM

    I wrote the applet in Netbeans and its working fine when I run it.
    Now I need to run this applet on a different laptop, which does not have NetBeans. It has C://postplotter.txt with the necessary data.
    I am using FileReader to read the .txt file :
    try {                                           // Extracting parameters from the .txt file.
                String url = "C://postplotter.txt";
                FileReader input = new FileReader(url);
                BufferedReader bufread = new BufferedReader(input);
                String[] line  = new String[15];
                for (int i=0; i<15; i++) {
                    line[i] = bufread.readLine();
                    System.out.println(line);
    Please let me know how to go about doing this. (Opening the applet on the laptop).
    I would like to be able to write an html file which has the applet embedded in it.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                   

  • Applet accessing local resources

    Hi,
    I am new to this group so pls forgive me in case I am asking an elementary question. I have a requirement wherein I need to print a receipt on the local printer directly from the application. I am using an applet to achieve the same. the problem is that the applet remains open after the first print and therefore does not init again.I am able to destroy the applet by shutting down the runtime - in which case my browser window (running the parent application) also goes down and I have to start all over again.
    I am sure there are other applications with similar requirements. Would be grateful if someone can help me out on this.
    k.karthik

    do you correctly use the init(), start() and stop()
    methods of the applet? I would assume so - the code itself is pretty simple
    import java.awt.*;
    import java.awt.event.*;
    import java.applet.*;
    import java.io.*;
    import java.net.*;
    import java.awt.print.*;
    public class PrintApplet extends Applet implements ActionListener, Runnable
    Button print;
    Label status;
    Label error;
    String ticket;
    Thread t=null;
    public void start()
    ticket="PRINTING THRU APPLICATION\n";
    setLayout(new FlowLayout());
    Panel panel = new Panel();
    print = new Button("Print");
    status = new Label("Click Print");
    error=new Label(ticket);
    panel.setLayout(new FlowLayout());
    panel.add(print);
    panel.add(status);
    panel.add(error);
    print.addActionListener(this);
    print.setCursor(Cursor.getPredefinedCursor(Cursor.HAND_CURSOR));
    panel.setSize(70, 20);
    panel.setBackground(Color.white);
    add(panel);
    setSize(200, 20);
    } //end of init
    public void actionPerformed(ActionEvent ae)
    error.setText("ENTERS ACTION");
    repaint();
         try
         String ticket="PRINTING THRU APPLICATION\n";
         String cmd = "/data/files/print.sh";
         Runtime runtime = Runtime.getRuntime();
    Process proc = runtime.exec(cmd);
    OutputStream os = proc.getOutputStream();
    os.write(ticket.getBytes());
    os.close();
    proc.waitFor();
    proc.destroy();
    runtime.freeMemory();
    runtime.runFinalization();
         runtime=null;
         catch (Exception e){error.setText("EXCEPTION");}
    error.setText("EXITS ACTION");
         repaint();
