Is that possible?? give me idea, How??

Hi all,
I am implementing online examination using Struts. ....
Is that possible that different-different candidates get same questions but in different order.
what i am trying to say is , I fetched the list of questions from DB and iterate it in the JSP but what i want is different candidates get it in a random order. means questions should b same but not in same order for each candidate.
Is that possible if yes then how give me some idea..
thanx

thanx for replying.....
but that would not work bcause I hit the DB only one time na for every candidates. My list is one(common) which display the Questions on the candidate screen.
even if it picks question randomly but at front-end it display all the quest in a same order to all the candidates.

  • First generation apple tv has lost its main menu bar on top of screen.  Also I am currently in language choice and my remote seems to be locked, is that possible and if so how do you unlock it?

    You would need to go to an Apple Store (make an appointment) and take the phone, her father's original invoice when the phone was purchased, and a copy of his death certificate. Only with these will Apple unlock it. If you can't get these, the phone is permanently unusable.

    What system and iPhoto version are you running?  What theme are you using.
    All of my calendars do have the month starting on Sunday,  Don't know of any way to change it.  Where are you located?
    How do you have your Calendar application's preferences set to, Sunday or Monday start of week?

    What version of Reader are they using, exactly? And are you sure they're
    using Reader itself and not opening the file inside a browser window, for
    example?

  • I want to create an "up to date" installation disk from my own one. So after installing the system shouldn't need to download any update. Is that possible? If so, how? Thanks.

    I know how to make an installation disk without things that I won't use and that can be burnt in a single layer DVD. But I want to make one that would be up to date with all the updates that have been released until now included.
    Is that possible? How do I download the updates? How do y include them in the DVD? I would be great if I don't have to isntall them manually after installing the macosx.
    I think there should be two ways of doing so:
    1.- Include the updates in the DVD and execute them after the system installation.
    2.- That the installation itself were up to date.
    Can anyone help me? Thak you.

    I don't believe it is. TimeCapsule restore would be limited to the same platform it was backed up from?
    I think what the OP is after is the idea of slipstreamed DVD including Snow Leopard *&* the latest combo updates. In the Windows world this is referred to as a slipstreamed install.
    For example you could have the latest build of SL plus the latest combo update slipstreamed in and this should work flexibly across a number of platforms.
    Unfortunately though I don't know if it's possible with OSX. It's a real time-saver in the Windows world though if you have a number of machines to deploy or if you're constantly building/assembling VMs for example.

  • Odd permissions issue that I have no idea how to fix

    Ok, so this is what happened. I gave my wife my old laptop, added her as a user and then deleted my home folder and account. I thought everything was fine but now the permissions in the applications folder aren't working properly. Even though she is listed as the administrator, every time she tries to update a program it says that she does not have enough permissions. So then she has to call me, i have to delete the application first and then drag the new one into the applications folder. What do I have to change so that she can rewrite applications?

    have her run the following terminal commands. The commands are in bold. Just copy and paste them into terminal please.
    *sudo chown -R root:admin /Applications*
    She'll have to enter her admin password (which she won't see). that's normal.
    This puts the ownership on everything in the Applications folder to owner=system, group=admin, which is the default for all apple apps.
    Next run
    *sudo chmod -R gw,X /Applications*
    This will give the group admin full write privileges to anything in the Applications folder.
    next run the following two commands to fix the ACLs that may be messed up.
    *sudo chmod -RN /Applications*
    and
    *sudo chmod +a "everyone deny delete" /Applications /Applications/Utilities*

  • I have a problem that iOS7 gives me headache, how to turn these features of?

    Hi,
    I do have a problem that when using iPhone with the new iOS7 I do get a headache, and so do several of my company employees. I have tried to turn of in settings but this do not help... I would be sad to have to replace all iPhones in the company, but the cost with employees becoming dizzy is quite bad.
    I hope that Appple do take this seriously, and will come up with a fix soon?

    Turn of parallax effect by going to
    Settings -> General -> Accessibility -> Reduce Motion and turn that off.
    Also I would keep brightness to minimal.

  • [CS4 / Win] Could you give me idea how to export indd to WMF?

    Hello,
    My task is exporting InDesign document to WMF.
    I tried to do the following:
    1. created kWindowViewPortBoss boss:
    InterfacePtr<IWindowPortData> pWinPortData(::CreateObject2<IWindowPortData>(kWindowViewPortBoss));
    2. got IWindowPortData interface and set SysPort which I created before:
    pWinPortData->Set(hWnd, hDC);
    3. created context for IDrawMgr::Draw:
    InterfacePtr<IViewPort> pViewPort(pWinPortData, UseDefaultIID());
    AGMGraphicsContextWith<AGMAcquireCoordSys, AGMAcquireClip> context(pViewPort.get(), PMMatrix());   
    4. called IDrawMgr::Draw:
    InterfacePtr<IDrawMgr> pDrawMgr(pWinPortData, UseDefaultIID());
    piDrawMgr->Draw(&context, page_item_ref, 0);
    The InDesign falls on IDrawMgr::Draw with access violantion error
    Is my way of exporting right?
    Which of my steps are not right?
    May be is there simpler method of exporting indd to wmf?
    Could you suggest to me directions where to look for solution of my problem?
    thank you in advance!

    Hi mate, thanks for the info, the original Server p09- etc remains in the box in Mail Preferences, but I went into
    System Preferences Mail section and entered your suggestion in the imap box.
    I ran a test email, IT WORKS!
    You certainly deserve to double your status of Level 2 (12,355 points).
    All my best wishes.
    Incidentally, I'm a retired electrician, so if anybody in the community needs a question answered, let me know.
