Do you trust java exception handling mechanism ??? If so, check all yours given permission one more time, try to find work examples how to do it.

  • AccessControlException in signed applet for simply reading local file

    I have a simple applet that reads specified local image files and uploads them to our server. On both Mac OS X and WinXP (firefox and IE7), I get the following error. I signed the applet using an InstantSSL code signing certificate (not so easy getting this to work, but I'm pretty confident I did it correctly).
    java.security.AccessControlException: access denied (java.io.FilePermission /Users/scott/Documents/photos/Ken_and_Scott.jpg read)

Interestingly, this file passed both file.exists() and file.canRead() checks within the applet (in windows the path is a bit different of course but also passes both those checks). Also, that file has no read restrictions and I can load it in a browser no problem.
    I assume I'm missing a step in the applet code signing process, maybe a step that says I'm allowed to read local files?

    I figured out my issue, the apache HttpClient library needed to be signed too apparently.

  • Signed applet not working in firefox - java.security.AccessControlException

    Hello,
    I have a signed applet that works fine in IE 7 but in Firefox I'm getting this exception in the java console:
    java.security.AccessControlException: access denied (java.net.SocketPermission myhost.com resolve)
    I already tried to run the applet with different JRE versions in Firefox with the same result: 1.6.0_01, 1.6.0_02, 1.6.0_03, 1.6.0_05
    I'll appreciate your help.

    thanx 4 replying
    using the browser to view Applet is not recomended that is because if u change the the source-code and recompile the applet then run it using the broswer it will run the old-version
    Also i've found the solution here

  • Signed applet sometimes throws AccessControlException

    Hello,
    Apparently I'm not the only one on this forum who's getting AccessControlExceptions in an applet. The strange thing is that I'm not getting them all the time.
    I have a signed applet that's requesting files from a server (http) in regular intervals (thread). When the server sends back a file, it's written to the local filesystem. There's also a logging mechanism that's write files to the filesystem. Normally this applet runs continuously for weeks, months, ...
    This system has been working fine for years now, until a few months ago. Now I sometimes get an AccessControlException while reading a System.getProperty or while reading file from the filesystem. Usually the applet runs fine for day without access problems and then suddenly I get a AccessControlException: Access denied on an action that wasn't a problem the last 1000 times it performed.
    My first thought was that it might be an update of the JVM that was causing it. So I tried downgrading to 1.5, even 1.4 and still got the same problem.
    Does any one has an idea what's causing this? I'm pretty much stuck on this problem.
    Thanks.
    Andy

    May be you have updated the .java files which are related to your applet and if u update the .java files, u need to recompile and need to re-sign the applets
    or
    When you are signing the applet you will tell, how many number of days I think that may be expired...
    otherwise no need....
    This may be one reason.... Once I faced
    May be this will help u

  • Signed Applet AccessControlException

    I am seeing some behaviour that seems very weird. I have a signed applet that is trying to connect to a JMS topic. However when I create the topic connection [topicConnectionFactory.createTopicConnection()] I get:
    java.lang.ExceptionInInitializerError caused by
    AccessControlException: access denied (java.util.PropertyPermission... read)
    This is unexpected because (1) the applet is signed, (2) I explicitly (and successfully) perform the following security checks before the createTopicConnection method call:
    security.checkPermission(new AllPermission());
    security.checkPropertiesAccess();
    If anyone has any suggestions, they would be greatly appreciated. Thanks, -mike.

    public class MySecurityManager extends SecurityManager {   
        /** Voids any Permission */
        public void checkPermission(java.security.Permission permission) {
        /** Voids any Permission */
        public void checkPermission(java.security.Permission permission, Object obj) {
    }Then in your applet add the following line within the constructor(s) or init method.
    try{

    } catch (AccessControException ace){
        // User didn't allow the signed applet
        JOptionPane.showMessageDialog(this,ace.getMessage(),"jMike :: Excepci�n",JOptionPane.ERROR_MESSAGE);
    ...The applet must be signed.
    MySecurityManager allows any permission, however, you can control the ones you want.

  • Signed applet accessing remote host getting AccessControlException

    I'm fairly new to java development, so hopefully this is an easy answer, but in my searching I haven't yet been able to figure out why this isn't working for me.
    I have a self-signed applet, running on a server in my intranet. I understood that using a signed applet would allow connecting to any host within the applet. In the applet, I'm using the following code to try to connect to a remote host, which is also in my intranet:
    import org.apache.commons.net.ftp.*;
    FTPClient ftp = new FTPClient();ftp.connect("[myhost]");
    //Where [myhost] is the name of the host I'm trying to connect to.This works fine when running from Eclipse Applet Viewer, but when I run from the website, I get the prompt to accept the signature and run. I click run. When the code above runs, I get the following exception:

    Bonjour,
    J'ai le problème que celui énoncé dans ce topic. Je réalise une applet ftp qui doit se connecter à un serveur ftp. J'utilise org.apache.commons.ftp.net et mon appli fonctionne sous eclipse mais pas intégré sur une page web.
    J'ai signé le jar commons-net-1.1.4.jar et le jar qui contient mon code et ça ne fonctionne pas.
    dois-je mettre toutes les classes de commons-net-1.1.4.jar dans mon fichier jar, je ne sais pas comment faire pour inclure commons-net-1.1.4.jar dans mon jar car lorsque je compile, je met le path dans eclipse mais je n'ai normalement pas besoin de mettre le commons-net-1.1.4.jar dans mon jar car les classes sont automatiquement importées.
    Merci de votre aide

  • Java.security.AccessControlException: access denied; for a signed applet

    Hi,
    I have a signed applet which is used to read local files. When I call the applet method which is reading the file, from javascript I am getting "java.security.AccessControlException: access denied ". Where as if the method gets called during applet load, file is read without errors? How can I get over this problem?
    If there is a way loading the applet based on a condition from Javascript, please let me know.
    Thanks,

    Ok I have found my problem :
    On every web pages, we have defined some inactivity timeouts.
    On my own server I have disabled these timeouts but not on the distant timeout.
    And it seems that the timeout (defined in javascript ont he web pages : 3s) has a very bad influence on the launching of my applet ... only with firefox (with IE and Opera no problem)
    My problem is anwsered but the problem keep alive for firefox ...

        }The above code is called by a java script, the class' constructor is empty.
    The error appears not to be caught by my code. I have tried to insert try/catch statements everywhere to figure out where this error is produced.
    The code is write off of the applet for signing with a smart card by Svetlin Nakov - and his applet works!
    I have also made a CLI application that uses the above code and it works perfectly.
    So: Something is wrong either with my certificate, the signing method, signature verification or something completely different. Any hints?
    The certificate I generated with
    keytool -genkey -keystore mystore -alias me
    keytool -seflcert -keystore mystore -alias meI have tired both with and without the selfcert step.
    Thanks! Erik

    The problem has been identified: Placing registerProvider() in the constructor the error no longer occurs, instead an error is produced when the key store is loaded.
    It appears that the javascript code is not trusted and so, even though the applet is signed, access privileges are restricted to those of the java script.
    A solution to this problem is not clear, but possibly, serving the pages from a trusted server, the java script will be trusted, some documentation seem to indicate.

  • Signed applet does not grant AudioPermission "record"

    From what I gather, if I have a trusted signed applet sitting on a webpage and
    the visitor accepts (runs) the applet, then they should not need to have:
    grant {
    permission javax.sound.sampled.AudioPermission "record";
    in their java policy file. Well I have done all this (with a certificate from
    Thawte) and posted a thorough example at:
    http://www.livesite.net/JavaSoundTest
    At the bottom of that page there is a "Check permissions" link which will alert
    true/false if we have record permission. Clicking any "Record" link will
    attempt to open a TargetDataLine.
    My experience (and problem) is: record permission must be granted even though
    the applet is signed by a trusted CA.
    I would very much appreciate any help.
    Are you able to record/playback (without granting record permission in your
    java policy files) with the JavaSoundTest applet webpage?
    Is there something I am missing?

    Is there something I am missing?1) Applets are not well supported by Sun,
    and are inherently problematic as a reult
    of that.
    2) My experience suggests that the diagnotics
    applet is not reliable for detecting JMF.
    3) I guess the JMF applet is doing checks of
    policy files, despite the signed code.
    You might circumvent most of these problems,
    by using web-start to launch an application.
    Here are some of my tests at launching
    JMF using web-start.

  • Signed applet throws security exceptions

    Since nobody seems to be reading the Signe Applet forum, I decided to try here:
    Hi all
    I have problems with signed applet (self-made cert), and after reading this forum I see this is more or less common.
    The problem that I am having is, that I can not use doPrivilege() and similar tricks, because applet needs to be Java 1.1 compatible.
    So, signing will have to work.
    Applet is signed using 1.5.0_06 jarsigner. Jarsigner verifies it OK.
    It works on JVM 1.5.0_06 but not on 1.4.2_08.
    Please help me make if work under any JVM.
    The error I get is:

    FATAL: java.lang.NullPointerException: nullWhat is funny, is that I have two applets, and one works and the other one doesn't. It is like this:
    Applet A (signed) needs to connect to host1, fails and tries to connect through proxy using my proxy library (also signed - different JAR). Everything works.
    Applet B (signed) needs to connect to host1, fails and tries to connect through proxy using the same proxy library. It gets a security exception.
    All JARs are signed using the same key/certificate.
    Both applets try to connect to the same "host1".
    Both applets try to use the same proxy - which is different from "host1".
    The one thing that might make a difference, is that in the working applet, everything is within one thread, and in the broken applet, the proxy object is in the main applet thread, and this applet may open many windows, that all utilize the same proxy object - only they can't.
    When I tried to move the proxy object down to the child threads, I get the following exception:
    Exception in thread "Thread-1952" java.security.AccessControlException: access denied (java.lang.RuntimePermission accessClassInPackage.sun.misc)

         at net.propero.rdp.applet.RdpThread.run(RdpApplet.java:211)It seems that I can only create the proxy object in the Applet.init() method, to avoid this exception.
    So to, summarize: I would prefer just one object for all threads that I will create, but then my applet behaves like it is not signed (at least under JVM 1.4.2_08). Java 1.5.0_06 doesn't have any problems with this.

  • Access denied to a security provider on a signed applet

    Hi,
    I'm having permissions problems to work with a security provider.
    The security provider is already installed at java.security. In fact, at Netbeans when debbuging the app it's working perfectly.
    If I'm working the provider in an signed applet, then there are errors.
    Even, I have created a .jar file and I have saved in the /ext directory, wich by default in the java.policy file has got all security permissions.
    grant codeBase "file:${{java.ext.dirs}}/*" {
    permission java.security.AllPermission;
    Even with these granted permissions, I'm getting problems to work with the security provider that I have installed. Also, with these permissions I should be able to install the security provider.

    Thank you for your information, Frank, as it clarifies part of my confusion. However, there are a couple more loose ends I'd love to address before I mark your responses as answers.
    Do backup and restore privileges apply at all over a network mount created via "net use"?
    The network mount requires a username and password for the destination machine. Assuming the destination machine is a Windows box with a simple CIFS share, how does this user affect our permissions and access? Do we end up effectively impersonating this
    user, or is the access check still done with our sync process's run-as user?
    We require that both our configured run-as user for our sync process *and* the credentials passed to the network mount be administrator users of the local system and destination system, respectively, meaning they're in of the "BUILTIN\Administrators,
    S-1-5-32-544" group.
    On re-syncs, the destination file will exist and since we don't have the ability to read the ACL in all cases (we're running as one user, the file is owned by another user, and we aren't specified in the ACL in any way), we aren't able to determine if the
    file has changed. Is it possible to determine the owner of this file in this case? Preferably, we'd obtain the entire SDDL.
    My proposed plan is to interpret access denied as a difference requiring re-sync, resulting in us taking ownership of the file, granting ourselves access, determining if there are data differences, and then re-syncing the metadata as appropriate.

  • My signed applet works with 1.4.1 plugin but it doesn't with 1.4.2_02 !!!

    Hi there, I've got problems trying to sign an applet with Java 2. That applet is an FTP which is used for uploading files throught the Browser (just upload).
    I signed my applet with SDK 1.4.1 when I surfed the page which contains it, the applet works properly (the browser had Java plug in 1.4.1) ... the certificate appeared (thawte), I clicked "Yes" for agreeing the certificate .. everything went fine. The problem was when I tried to navigate that page with a Browser with Java Plug in 1.4.2, I agreed the cetificate, but when I tried to upload a file with the applet the following error happens :

    I signed tha applet again and it didn't work ...
    please ... I need help!
    Thanks in advance.
    Nico.

    Funny, I had a problem going to _03 when it worked fine in _02. Symptoms: In IE, Sun's plug-in displays security warning prompt for signed applet, and, even though the user clicks YES to accept, all priv operations cause exceptions. It sounds like what you're referring to, but I'm wondering why I didn't see it in _02. Anyway, I'm going to look into the doPriv... stuff to see if that fixes my prob and I'll report back FWIW.
