Need help re applet and oracle thin

I'm having with applets when it comes to connection to the database. Here's what happened I want to integrate my Elixir report to my applet application I compiled it and I saw no error. But when I tried to run a dialog box appeared into my screen with a message
"java.security.AccessControlException:access denied(java.util.PropertyPermission oracle.jserver.version read)"
what's wrong with this I don't know what to do already hope you can help me figure out what's wrong with my program tnx.
here's my html code:
<!doctype html public "-//w3c//dtd html 4.0 transitional//en">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">
<meta name="Author" content="Shem Kua">
<meta name="GENERATOR" content="Mozilla/4.61 [en] (Win98; I) [Netscape]">
<title>PPI Reports</title>
</head>
<body>
<applet codebase="./" code="ReportApplet" archive ="report.jar,elxrt.jar, ojdbc14.jar" width=780 height=480>
<param name=mode value="appletviewer">
<param name=dsmfile value="sav/ppi.sav">
<param name=template value="templates/ppi.template">
</applet>
</body>
</html>

In contrast to what many people say in this forum, it is possible to have an unsigned applet access a database. You don't even have to manipulate the client's policy-file. The requirement is that the database is located on the same machine as the applet is downloaded from.There are however other things that can break this possibility. One is the database-driver itself.
In the case of Oracle we have tried using different versions of the driver. When using version 8.1.7 or 9.0.1 things work nicely, but when switching to version 9.2 it stops working. There is a question on OTN [1]. Let's see what Oracle has to say about it.

  • I need help with Applets and Multithreading

    [hello all.  first time poster. big fan of java.]
    now to the important matter: Applets and Threads
    =======================================
    1) I have an applet with that implements the runnable interface, and has one thread (and a simple animation). If I try to view this applet in the applet viewer with JGrasp, it spits an insane error telling me
    "java.security.AccessControlException: access denied (java.lang.RuntimePermission modifyThreadGroup)"
    but, if I run the applet through a web browser, by putting it in an html document, it runs correctly, without error
    What on earth is wrong, and how do I fix it?!?
    2) I want to put 2 threads in my applet?
    If I implement the Runnable interface, I can only have one Run() method in my applet, right?
    So how do I define behaviour for 2 threads when I only have one run method in which to define the behaviour? Can I use two threads with the runnable interface, or do I have to make objects of my own defined thread classes?
    3) I tried to make 2 threads in my applet by creating my own thread classes, and instantiating them in my applet (instead of implementing the runnable interface).
    I still get the same insane error as I mentioned in my first point (which I expected), except now, the applet won't work even when viewed through a web browser!!
    Please please help me. I am frustrated beyond belief (at what is probably a very simple problem)
    I have searched and searched all over and found no answers on this

    If I try to view this applet in the applet viewer with JGrasp, it spits an insane error telling me
    "java.security.AccessControlException: access denied (java.lang.RuntimePermission modifyThreadGroup)"Don't know anything about JGrasp, but it runs with pretty tight security - thats what this insane error is all about. Use the appletviewer or a browser.
    If I implement the Runnable interface, I can only have one Run() method in my applet, right?Correct
    So how do I define behaviour for 2 threads when I only have one run method in which to define the behaviour?
    Can I use two threads with the runnable interface, or do I have to make objects of my own defined thread classes?You can create two Runnable implementations (classes) in your applet.
    example (missing code)
    class MyApplet extends Applet {
      void doSomething() {
      void doSomethingElse() {
      void startThreads() {
        Thread t = new Thread(new Runnable() { public void run() { doSomething();}});
        t.start();
        t = new Thread(new Runnable2());
        t.start();
      class Runnable2 implements Runnable {
         public void run() {
           doSomethingElse();
    }If the above seems confusing, read up on anonymous and inner classes.
    3) I tried to make 2 threads in my applet by creating my own thread classesTry not subclassing thread - this causes a security check

  • Method getCustomDatum() and Oracle thin client

    Hello All,
    I am using WL6.1 and an Oracle thin driver. I am using the Oracle Intermedia classes
    for Java in order to retrieve images for jsps and servlets.
    Trying to use the Oracle classes caused class cast exceptions. When using the
    weblogic.jdbc.vendor.oracle.OracleResultSet, I got the error
    "java.sql.SQLException: getCustomDatum is not supported by the Weblogic JDBC Driver".
    I was wondering if anyone else has run into this problem? Any help would be greatly
    appreciated.
    Thanks,
    Rich

    Slava,

    Do you mean that I need to get to get a connection directly to thedatabase using
    the Thin driver instead of getting the connection via the pool?Yes, this is the first option. Note that with using thin driver directly
    you loose all advantages of using weblogic JDBC subsystem like
    transactions, connection pooling and caching of prepeared statements.
    I'd go with a stored procedure.

    Hi Richard,
    This feature is not supported by weblogic because
    oracle Datum is not serializable. In case you have a
    strict requirement, you will need to switch to using
    oracle thin driver directly. You could also consider
    moving processing to stored procedure.

  • Need help to import and syncronize HCM pagelets with Interaction Hub, how can I do that?

    Hi,
    I need help to import and synchronize HCM pagelets with Interaction Hub, how can I do that? The default page "Select Remote Content" of the WorkCenter "Unified Navigation WorkCenter" is not working as well, when I run the import/sync button I get the following error message:
    Integration Gateway: General Connection Failed (158,10836)
    This error is thrown when there is no valid response.
    Possible errors include:
    Bad gateway URL
    Sync Service Timeout set and Service actually timed out.
    Java exception thrown - Check Application Server for possible Java exception

    Do you have integration configured between the two systems?  It sounds like you don't from the error.  Here is a walk-through on setting up Unified Navigation although it assumes you have integration already working.  If you haven't done that, it's documented a hundred different places.

    That's going to be a ridiculous waste of money and energy.
    First of all, the current ATI drivers don't support multiple GPUs, so at the moment even a single 4870X2 would be only a 'normal' 4870 (which is quite a speed beast already). GFX drivers evolve rapidly, so things might look different next month, but when it comes to Linux and hardware there's one Golden Rule: stay away from the newest stuff and wait for proper support to get coded.
    I also wonder what power supply could possibly cope with the differences between idle and full load; that's way beyond 400W. But then, I'm one of those "quiet&green" types where >100W idle is already a bit much.
    I kind of understand that you want to get it done and not worry about hardware for the next 10 years or so, but that's simply not how the hardware world works and never did. At least not for the average consumer.

    I need help locating where and how to update Mac OS-X to Mountain Lion.....Thanx....Jay

    First update your 10.6 version to 10.6.8 from the software update under the Apple Menu.
    This will add direct access to the Mac App store via a new application.
    Now launch the App Store from your Applications folder - Its the new icon a letter A formed from a ruler pencil and pen on a blue circle !
    Once launched you need to add your iTunes account details or create an account add payment details etc...
    Sign in purchase download and follow install processes to upgrade to 10.8 Mountain Lion.
    OH and to be safe BEFORE you install backup your current system to an external drive !

  • This is a second try to get help. I need help to uninstall and reinstall Photoshop cc 2014

    Bridge is not working well, I need to reinstall Photoshop cc 2014 .  Someone from Communities was suppose to help me. 

    Hi John,
    I used the chat "Creative chat support"  this afternoon at around 14:40
    and the person, Karthik M , gave me a link to Technical Support.  I
    guess he could not help me, but he said he understood the issue.   With
    the link "Help, Adobe Installation problems",   I will follow the
    instructions  to clean ps cc2014 with CCleaner and reinstall the app.  
    It looks quite complicated  but I will give it a try and hopefully succeed.
    You have to understand when reading my previous messages, the issue is
    no longer "Retreiving Photoshop CC" but reinstalling Phoshop 2014 to try
    to repair Bridge.
    Thanks for caring,
