Hi
You know JDO? It's very like it but Hibernate more strong than that.
Hibernate is an O/R Mapping technology.It is used to map database table to entity object.(like EntityBean). jsp+DAO+Hibernate. Hibernate is a light wrapper of jdbc. See so www.hibernate.com

  • My hard drive crashed on my macbook pro and I had a new one installed and they were unable to get my pictures off of it. Is there anyone who could help? I'm going to lose all my memories of my kids! I got my old hard drive

    My hard drive crashed on my macbook pro so i had a new one installed and they couldn't get my pictures off. I dont want to lose all my memories! They gave me back my old hard drive. Is there anyone that could help me?

    I think how you understand the value of having backups. All you can do is:
    General File Recovery
    If you stop using the drive it's possible to recover deleted files that have not been overwritten by using recovery software such as MAC Data Recovery, Data Rescue II, File Salvage or TechTool Pro.  Each of the preceding come on bootable CDs to enable usage without risk of writing more data to the hard drive.  Two free alternatives are Disk Drill and TestDisk.  Look for them and demos at MacUpdate or CNET Downloads. Recovery software usually provide trial versions that enable you to determine if the software would help before actually paying for it. Beyond this or if the drive has completely failed, then you would need to send the drive to a recovery service which is very expensive.
    The longer the hard drive remains in use and data are written to it, the greater the risk your deleted files will be overwritten.
    Also visit The XLab FAQs and read the FAQ on Data Recovery.
    You will need an external enclosure for the old drive so you can connect it to the computer in order to try the recovery software before you buy it. But if they don't work then you will need to send the drive to a recovery service such as Drive Savers.

  • I have a problem, i can't change my lockscreen wallpaper after i upgrade my iphone 4s to ios 5.1.1... Is there anyone who can help me?

    I have a problem, i can't change my lockscreen wallpaper? Doesnt work...is there anyone who can help me regarding this problem? Thx

    To help, we need more detailed information.
    --What steps are you trying?
    --What does the device tell you (any pop-ups or messages)?
    --Are you able to change the Home screen wallpaper, or is that affected too?
    --Are you the phone's owner/administrator, or is this a device used for work (assigned/administered by IT staff, possible on an Exchange server)?
    --Have you jailbroken the device?

  • I have installed ios7 on my iPad 4. After installation it asked me pass code which I have never set. After multiple attempts it is disabled. I don't have backup on my iCloud or iTunes. Is there anyone who can help to enable it or to reverse iPad to ios6.

    I have installed ios7 on my iPad 4. After installation it asked me a pass code which I have never set. After multiple attempts it is disabled. I don't have backup on my iCloud or iTunes. Is there anyone who can help to enable it or to reverse iPad to ios6. I asked Apple store & tech said to format it but I will lose all the data..!

    Thanks for that. Much more constructive than the last comment. It's only the restriction code I can't recall, not the access passcode. So I can currently access the device, just not age restricted content. Does that's make a difference? I also wondered if anyone knew how many attempts you get to try to get it right. Now tried 21 times and so far nothing bad has happened but I am concerned I'll eventually be completely locked out of the device. That doesn't seem in the spirit of things though. Surely it's foreseeable that a child could repeatedly try to guess the code so I can't see that it would be right to lock the device down completely in that circumstance, particularly if the access code is being typed in correctly every time.
    Thanks

  • Has anyone used MC Helper to reset hotmail on their Mac?

    Has anyone used MC Helper to reset hotmail on their Mac. I just did and I'm am worried as I gave them access to my computer over the phone. They have solved access to my hotmail account though, but they charged $200 for it plus a years free support. I was very suspicious but in the end went ahead. I now fear that they may be a scam of sorts. They could have implanted or encrypted something on my mac. Is this likely? Does anyone know? I'd be most grateful.

    LogMeIn Rescue is for one time support. This is a common tool used to support users. Microsoft uses it when they do support. I use one of the LogMeIn products myself when working with clients.
    In the future if you need help with a Microsoft product you can get free help on the Microsoft forums.

    Hi there,
    A few days ago i wrote a thread in project swing forum about a problem that i have with the JFileChooser and the fact that i am not able to set the focus to a different JComponent...
    http://forum.java.sun.com/thread.jsp?forum=57&thread=200362
    I am using Java sdk 1.3 and i know that this problem is already documented in the bug database however the work-around concept does not seem to work...
    http://developer.java.sun.com/developer/bugParade/bugs/4373112.html
    Which is what i am currently trying to do...
    Could please anyone help me with this?
    I am really sorry for anoying everyone with this but i tried twice in the swing forum and nobody seems to know any work-arounds...
    Please help!
    Kind reagrds,
    John

    In order to change component that takes the focus when the JFileChooser is shown you have to change it after it has been shown using chooser.showOpenDialog(null) (for instance). As it is shown in a dialog, you don't have the chance to access the chooser in this thread. Don't worry I am not about to demonstrate a wild way to do this with threads and such rubbish.
    The way to do it is to add a ComponentListener to the file chooser before you show it.
    java.awt.ComponentListener interface exposes 4 methods.
    componentHidden(ComponentEvent ev);
    componentMoved..
    componentResized..
    componentShown..
    so, all you need to do is implement the 4 methods like this
    chooser.addComponentListener(new java.awt.ComponentListener() {
    // Methods missed out for brevity
    public void componentShown(ComponentEvent ev) {
    // Do your thing to find the component and have it take the focus,
    then show the chooser.
    I cannot guarantee that this works as I have not tried it however that should do the job. Focus cannot be changed until the component is actually visible so...

  • I am having a weird problem while attempting to re-install iTunes, is there anyone who can help?

    Its kind of an odd problem, never happened to me before, but my old iTunes was very outdated because my updater was not working, and today having to actually use iTunes but it was very outdated, I read on the apple support site that the only way to update my version was to delete and re install.
    Upon completely deleting iTunes and all other related software (following the steps given here:http://support.apple.com/kb/HT1923), and then installing the latest version of iTunes from the apple site, I still receive the very same error message about a quarter way through the installation saying 'Error, object already exists', and when I click ok it pops up a few more times until the iTunes install wizard says there was an installation error and to either finish or try again.
    I really need to use iTunes asap for some important business so any help would be much appreciated.
    Additional info:
    Operating system is Windows 7
    Computer is a Dell
    Downloaded using Google Chrome

    For general advice see Troubleshooting issues with iTunes for Windows updates.
    The steps in the second box are a guide to removing everything related to iTunes and then rebuilding it, which is often a good starting point unless the symptoms indicate a more specific approach. Review the other boxes and the list of support documents further down page in case one of them applies.
    Your library should be unaffected by these steps but there is backup and recovery advice elsewhere in the user tip.
    The section Install missing components has advice on breaking down the iTunes installer into the individual .msi files which might prove useful if iTunes won't install normally.

  • Is there anyone who can help me out in this!!!!

    Trying this for the fourth time........
    Hi gurus,
    I have posted this thread earlier also but didnt get any response, so I was just wondering did I ask something unrealistic?
    Hi gurus,
    I am working on an interface where I will be getting the production order number and then based on this order number I need to update some fields in transaction code ... CO11N...such as Quantity produced, reason of variance, batch number and posting date. So what I believe is first I need to pass the order number to the BAPI_PRODORD_GET_DETAIL to get the details of the production order and then update the production order by using the BAPI_PRODORDCONF_CREATE_TT, but my problem is I am new to ABAP I got to know what should be the process but I am not being able to implement it. So basically the program needs to pick the data from the internal table and copy it in SAP. My internal table looks liks
    data : BEGIN OF it_input occurs 0,
    order_no like afko-aufnr, "Order Number
    opr_no like afru-vornr,
    quant like afru-lmnga,
    varian like afru-grund,
    budat(10) type c,
    matnr like caufvd-matnr, "Materials
    erfmg like cowb_comp-/cwm/erfmg,
    charg like mcha-charg,
    END OF it_input.
    So can you please help me out in this..I mean step by step or if there is any other suitable way.
    Thanks,
    Rajeev .......

    Rajeev,
    Based on your post, just may not be clear what you are asking for then.
    I think your general approach that you have described is correct.  Without knowing the source of your data for the internal table, it is hard to completely provide an answer but a typical interface might look something like this:
    1.  Selection screen with parameters for the file name (If a file is the source of your data)
    2.  Load data from the file into your internal table.
    3.  Loop at your data
    4.  Call the Get Detail BAPI
    5.  Using the data returned from the get detail BAPI and your internal table create the importing, exporting, tables parameter for your Create BAPI.
    This step might need some more clarification.  I am not sure if you are using the right BAPI for what you are trying to accomplish.  First this appears to be a Create function and not a change, second, it appears that this is for Time Ticket information against a production order.  I haven't used any BAPIs for production orders before so I can't give you a definite answer.  If you cannot find an appropriate BAPI, you might also try creating a BDC/Call transaction update.
    6.  Review the error messages/return code from your production order change
    7.  Output some type of report to the user regarding successful updates, errors, etc.
    I hope this helps provide some guidance.
    Best Regards,
    Chris H.
