File reader in applet?

Can anybody tell me if it's possible to use the filereader in an applet? Because i am trying to fill a list using a file on init and I am getting a java.security.AccessControlException: access denied (java.io.FilePermission urlFile.txt read)
error.

1. I'm not sure how to sign an applet cause i've never done it before... could you provide some assistance?
2. what kind of tweaks would you suggest that i make ? that i might need

  • Reading and writing to a text file from an Applet

    I'm a novice java programming with very little formal programming training. I've pieced together enough knowledge to do what I've wanted to do so far...
    However, I've been unable to figure out how to read and write to a text file from an Applet (I can do it from a normal java program just fine). Here is a simple example of what I'd like to do (you can also look at it on my website: www.stat.colostate.edu/~leach/test02/test02.html). I know that there is some problem with permission/security but I'm not smart enough to understand what the error messages are telling or understand the few books I have. If anyone can tell me how to get this applet to work, or direct me to some referrences that would help me out I'd really appreciate it.
    Thanks,
    Andy

    I have almost the exact same problem, and I am in the same situation as you are with respects to the language.
    I am simply trying to create a file and output some garbage to it but my applet always spits back a security violation. I've tried eliminating the restrictions on the applet runner I use but I still get the error.
    My method:
    debug = new Label() ;
    debug.setLocation( 20, 20 ) ;
    debug.setSize( 500, 15 ) ;
    add( debug ) ;
    // output
    try
         OutputStream file = new FileOutputStream( new File( "" + getCodeBase() + "output.txt" ) ) ;
         byte[] buffer = { 1, 2, 3, 4, 5 } ;
         file.write( buffer ) ;
         file.close() ;
    } catch( Exception e )
         debug.setText( e.toString() ) ;
         Can anyone tell why this isnt working?

  • Reading a data file from an Applet

    ...new to Applet Programming. I have a stand-alone application that converts
    an XML file to a DOM, then to a JTree. I have converted the application to an Applet
    But I can't find the trick to having the applet connect to the XML file.
    This is the line of code which works fine in the stand-alone, but hangs the Applet:
    document = builder.parse( new File( "P6B.Xml" ) );
    How can the applet read data located on the host in the same directory as the class?
    Sounds simple, but somehow can't find a way of doing this.
    One suggested solution (when the file is always needed) I have found browsing
    through this site is to wrap both the File and the Class in a JAR.
    In this instance, how can I parse the file?
    Appreciate any help.

    Give the complete URL of your xml file.

  • Is it possible to read a text file into an applet?

    I have a text file that contains data I want to use in my applet. Is there a way to read in the data?
    Thanks,
    Brad

    With a signed applet you can read a file from the local hard disk. There is a forum for signed applets. The source code of your signed applet will require some additional code (before opening and reading the file, like // create a permission object
    FilePermission perm = new FilePermission("path/file", read);
    // check the permission object
    AccessController.checkPermission(perm);

  • How do I update a file in an Applet's JAR file from the Applet code

    Here's my problem.
    My applet is using a serializable history data in which I am storing in the applet's JAR file. When I run the applet, I read the file with "getResourceAsStream()" and run my program with that hist data. When my applet is closed, I need to update this file from my Applet's code and I dumfounded about how to do that.
    Is there any way to update a file in the Applet's JAR file through the Java Applet code? (i.e. OutputStream?).
    Would appreciate any advice people have.

    Just place a copy of the file on the local hard disk and update that. When you start the Applet you try to read from the hard disk. If the file exists then no problem otherwise copy it from the jar to the hard disk.

  • Add a jar file to an Applet

  • Exporting to a text file in an applet..

    Hey all,
    I've been working on an applet for simulating different nodal configurations on a 2D map. What I need to be able to do is export, on the click of a button, all of the nodal coordinates (x,y) to a text file. However, using the standard FileWrite hasn't been working for me. The code compiles and the applet runs fine, but I haven't been able to create the text file on the click of a button. Any ideas?
    Here's what I've got so far. Basically, on the button push, it's supposed goes through an array of ellipses (what I use for nodes) and gets the x and y coords for each and output them to a text file. The applet doesn't freeze or anything when I push the button either, it just does nothing.
    void stop_actionPerformed(ActionEvent e){
                try
                        String fileName = "NodeCoords.txt";
                        FileWriter fileWriter = new FileWriter( fileName );
                        BufferedWriter bufferedWriter = new BufferedWriter( fileWriter );
                        String tmpCoordinates;
                        int ID;
                        //for looop through x-y coordinates
                        for (int i = 0; i < node.length; i++){
                            ID = i+1;
                            tmpCoordinates = "Node: " + String.valueOf(nodeID[ID]) + "  X: " + String.valueOf(node.getX()) + " Y: " + String.valueOf(node[i].getY()) + "\n";
    bufferedWriter.write(tmpCoordinates);
    bufferedWriter.close();
    catch( IOException p )
    p.printStackTrace();

    I'm new to this type of programming. This is for simulation of a new MAC protocol that I've worked on, and is basically just serving as a visual. If I knew how to create a stand alone application that looks like the applet I would have...

  • Error: cannot read: {My applet name}

    I write the little program in Notepad and save it in C:\JDK1.3.1_02\bin\. Then I go to Command Prompt and
    type: javac {My applet name}. I then get the error: ERROR: CANNOT READ: {MY APPLET NAME}

    This {My applet name} have the same name of your class? The Java don't compiles if your class name has different of the files name . Another Error that can be possible that you files it's read only in their properties. What you can make is enable your file for full access.

  • File handling in applets

    i am doing a project in applet.
    i want to open file from that applet
    but appletviewer told below error,
    java.security.Exception (Access is dinied )
    but
    that same problem is solved in ordinary java program(not in applet )
    if applet is not supported for file I/O then any other idea.

    Signed applets seldom a good solution, though. I agree. I suspect most people who have this sort of problem chose applets for one of two reasons:
    1. Applets were the first thing covered in the book they were reading.
    2. They hoped it would be a short way to deploy their code.
    The correct reason to choose an applet would be because it was a useful feature for your web site.

  • How to check file exist in applet?

    I would like to check the existance of a file from an applet. How can I achieve that? I'd tried many attempts but still fail to get an answer. Please kindly help.
    Below are my file structures:-
    folder/applet/myApplet.java
    folder/appletView.jsp
    folder/image/image1.gif
    I would like to check if image1.gif exist. if yes, then load and display it in applet, but I having problem on the how to specify the file location.

    Assuming image1 is in the same folder as the applet:

                        // now failing to read the inputstream does not mean the server did not send
                        // any data, here is how you can read that data, this is needed for the same
                        // reason mentioned above.
                        ((HttpURLConnection) urlc).getResponseCode();
                        InputStream es = ((HttpURLConnection) urlc).getErrorStream();

  • File Uploader Java Applet cannot be run

    I have a website that I need to upload PDFs to, but since ugrading to Lion, I cannot do it any more.  I have downloaded the separte Java app, but it still does not work.
    This is the error message I get:
    File Uploader Java Applet cannot be run. Make sure that Java is installed on your PC and Java applets are permitted in browser settings. Use this link to download and install appropriate version of Java:

    Thank you etresoft - that did not solve the problem.  However, I did fix it by changing something in Java Preferences (which is located in the Utilities Folder).
    I first deleted the cache files as you suggested in the Network tab.  Then I quit and restarted Firefox.  I still got the same error message when I tried to upload.
    Then, I went back into Java Preferences and checked the box, "Enable Appplet Plug-in and Webstart Applications" located in the General Tab.  I then quit and restarted Firefox.  Now I am able to upload documents as I could before Lion.
    Thank you!!

  • Output to a text file in an applet...

    i can't figure out how to do output to a text file in an applet... i've gotten output in applications, but nto applets. if someone can give me a link to a site that explains this, i would be much appreciative.

    There is no easy way, since accessing Files with write permissions is a security issue. You can sign the JAR your applet is in, and use Security managers to try and get around it, but it is quite complicated I believe.
    Do a search for Security Signed Applets etc...
