I am using jdk1.5 for my development...
Can anyone help to resolve this security issue. Urgent...
Thanks in advance.

Hey thanks. I wasn't able to get it to work with that sample but I did find this very similar code that does allow javascript to call JFileChooser in an applets public method.
java.security.AccessController.doPrivileged(
new java.security.PrivilegedAction()
public Object run(){                           
//do your special code here
return null; //return whatever you want
It seems a bit tempermental in that if you don't select a file quickly, it will hang the browser....no perfect solution but I'm going in the right direction.
Thanks,
Scott

  • Problem with access to SipFactory from jsp-pages in JBoss environment

    Hello!
    I have an installation of the OCMS 10.1.3.3. deployed into a JBoss (jboss-4.0.5.GA) environment. Unfortunately I have a problem with accessing the SipFactory from a jps-page. Encouraged by the "messagesender" example I tried to get an instance of SipFactory from my jsp-page simply by calling:
    SipFactory sipFactory = (SipFactory) application.getAttribute(SipServlet.SIP_FACTORY);
    But unfortunately there seems to be no attribute "SipServlet.SIP_FACTORY" and I only get a null pointer. I have also tried running that code in the orignal messagesender example but it didn't work either. So I wonder if this should definetely work in a JBoss environment or if this might be a known problem. Is there anything that I could check/do regarding this problem? I suppose there must be an oracle module which should take care of making the SipFactory availabe after it is deployed. Perhaps something went wrong during the deployment?!
    Best regards,
    Tim

    Hi
    On JBoss, OCMS does not support converge applications.
    I.e the SipFactory can be retrieved from the servlet context when running on OC4J.
    Instead the SipFactory can be found in JNDI as described in the Developer's Guide:
    "External Access to SIP Servlets
    To enable convergent applications between SIP and HTTP, the OCMS Container allows you to get access to the javax.servlet.sip.SipFactory by looking it up through JNDI. The SIP Factory will be registered under the same name as the display name of your SIP servlet as illustrated in Example 2–12. The <display-name> in the sip.xml in this case must be "My sip app".
    Example 2–12 Accessing the Data for a SIP Session through JNDI
    InitialContext ic = new InitialContext();
    SipFactory sipFactory = (SipFactory)ic.lookup("sip/My sip app");"
    Cheers

  • Calling1.4.1 signed applet from Javascript causes keyboard/focus problems

    Pretty sure there's a JRE bug here, but I'm posting to forums before I open one in case I'm missing something obvious :-)
    This issue may be specific to IE, I haven't tested elsewhere yet. Our web application is centered around a signed applet that is initialized with XML data via Javascript. We first noticed the problem when our users started upgrading from the 1.3.x plug-in to the 1.4.x plug-in. The major symptom was that shortcut keys stopped working. I debugged the problem off and on for about a month before I boiled it down to a very simple program that demonstrates the issue (included below). Basically, the program has a function that adds a JButton to a JPanel and registers a keyboard listener (using the new DefaultKeyboardFocusManager class) that prints a message to the console. This function is called by the applet's init() method, as well as by a public method that can be called from Javascript (called callMeFromJavascript()). I also included a very simple HTML file that provides a button that calls the callMeFromJavascript() method. You can test this out yourself: To recreate, compile the class below, JAR it up, sign the JAR, and put in the same dir with the HTML file. Load the HTML file in IE 5.0 or greater, and bring the console up in a window right next to it. Now click the button that says init--you should see the small box appear inside the button that indicates it has the focus. Now press some keys on your keyboard. You should see "KEY PRESSED!!!" appearing in the console. This is proper behavior. Now click the Init Applet from Javascript button. It has removed the button called init, and added one called "javascript". Press this button. Notice there is no focus occurring. Now press your keyboard. No keyboard events are registered.
    Where is gets interesting is that if you go back and make this an unsigned applet, and try it again, everything works fine. This bug only occurs if the applet is signed.
    Furthermore, if you try it in 1.3, signed or unsigned, it also works. So this is almost certainly a 1.4 bug.
    Anyone disagree? Better yet, anyone have a workaround? I've tried everything I could think of, including launching a thread from the init() method that sets up the components, and then just waits for the data to be set by Javascript. But it seems that ANY communication between the method called by Javascript and the code originating in init() corrupts something and we don't get keyboard events. This bug is killing my users who are very reliant on their shortcut keys for productivity, and we have a somewhat unique user interface that relies on Javascript for initialization. Any help or suggestions are appreciated.

    I tried adding the requestFocus() line you suggested... Same behavior.
    A good thought, but as I mention in my description, the applet has no trouble gaining the focus initially (when init() is called). From what I have seen, it is only when the call stack has been touched by Javascript that I see problems. This is strange though: Your post gave me the idea of popping the whole panel into a JFrame... I tried it, and the keyboard/focus problem went away! It seems to happen only when the component hierarchy is descended from the JApplet's content pane. So that adds yet another variable: JRE 1.4 + Signed + Javascript + components descended from JApplet content pane.
    And yes, signed or unsigned DOES seem to make a difference. Don't ask me to explain why, but I have run this little applet through quite a few single variable tests (change one variable and see what happens). The same JAR that can't receive keyboard events when signed, works just fine unsigned. Trust me, I'm just as baffled as you are.

  • Problems with RSA Signed Applets methods called by JavaScript

    Hi Folks,
    I need to give all permissions to an Applet used in an Intranet application, so I signed the jar containing it with a RSA self-cert and I did the same for all the other jar files userd by the applet.
    The applet runs under Java Plugin with JRE 1.5.0_06: I am requested by the browser to install the cert and all works fine.
    When a JavaScript function calls a public method of the applet I received a security exception when the code tries to read a system property.
    The same method works fine if called by the applet itself or by a gui event (i.e. a button click) inside the applet, so the problem seems to be related to the fact the applet is used by JavaScript (in Explorer 6).
    Does anyone know some way to overcome this problem????

  • Calling a method in a signed applet from JavaScript does not do anything. Same functionality works in IE, Safari and Chrome. Is this a limitation of the JavaScript implementation?

    It does not seem that the JavaScript engine in FF 4 is allowing me to call inside a signed Java applet. When calling the script the browser does not do anything. The same functionality works in IE, Safari, Chrome.

  • Problem with a sign Applet - certificate isn't recognized

    Hello to all the java experts
    I have created a certificate using keytool. I have exported the certificate and installed it on the computers of the users. The certificate worked well on all the computers except one. I have got a message:
    java.security.cert.certificateException unable to verify the certificate CA root
    I want to add that when I installed this certificate I got a message that it was imported successfully and I have also seen that the certificate is valid. I imported it by double-clicking on the crt file and choosing "install certificate". I also tried to import it by using the command: keytool -import -alias company -keystore carets -storepass changeit -file c:\crtfile.crt.
    I have checked that the certificate was imported by the command:
    keytool -list -v -keystore company
    The only thing which is different on this computer is the plugin of swing (1.3.01 and not 1.3.02)
    What can cause to this problem? How can I fix it?

    Noone has any idea?

  • Cisco ASA 5505 - problem with negotiating IP address from PPPoE

    Hi all,
    I have problem with negotiating IP address from PPPoE. There is following design: ISP providing vDSL ending on VDSL modem in bridge mode. Behind brigde modem is ASA 5505 terminting PPPoE on OUTSIDE. Everything works fine except  negotiating IP address from PPPoE server.
    I have configured ASA 5505 with (ASA Version 9.2(2)4) for PPPoE like this [1.]. But If i try to "show" IP address on OUTSIDE interface a get this [2.], ok strange but let's continue. If list "show vpdn pppinterface id 1"  i get this [3.]. Seems that I got public IP addres what was right, but this IP address was not associated with interface OUTSIDE?
    Well, if I set IP address manually like this [4.] and also set a default route everything works fine but what will happen when ISP change reservation for my IP address or default gateway. 
    I have tried different version of ASA OS like 8.4, 9.1 but without luck. 
    Can anybody help me. Thanks a lot.

    You're right that the ACL should not affect otherwise allowed communications to the interface address.
    Try disabling the ip audit feature on your outside interface.

  • Problem with focus on applet  - jvm1.6

    Hi,
    I have a problem with focus on applet in html page with tag object using jvm 1.6.
    focus on applet work fine when moving with tab in a IEbrowser page with applet executed with jvm 1.5_10 or sup, but the same don't work with jvm1.6 or jvm 1.5 with plugin1.6.
    with jvm 1.5 it's possible to move focus on elements of IEbrowser page and enter and exit to applet.
    i execut the same applet with the same jvm, but after installation of plugin 1.6, when applet gain focus don't release it.
    instead if i execute the same applet with jvm 1.6, applet can't gain focus and manage keyevent, all keyevent are intercepted from browser page.
    (you can find an example on: http://www.vista.it/ita_vista_0311_video_streaming_accessibile_demo.php)
    Any idea?
    Thanks

    Hi piotrek1130sw,
    From what you have described, I think the best approach would be to restore the original IDT driver, restart the computer, test that driver, then install the driver update, and test the outcome of installing the newest driver.
    Use the following link for instructions to recovery the ITD driver using Recovery Manager. Restoring applications and drivers.
    Once the driver is restored, restart the computer and test the audio. If the audio is good you can continue to use this driver, or you can reinstall the update and see what happens. IDT High-Definition (HD) Audio Driver.
    If installing the newest driver causes the issue to occur but the recovered driver worked, I suggest recovering again.
    If neither driver works I will gladly follow up and provide any assistance I can.
    Please let me know the outcome.
