Can I combine @Id & @Temporal?

I recently upgraded my IDE and it is flagging the following field in an Entity:
@Id
@Column(name = "HitDate", nullable = false)
@Temporal(TemporalType.DATE)
private Date hitDate;The error is that there is "More than one attribute configured for field hitDate."
I probably wouldn't have chosen a date field as the id for this table, but I can't change the design at this time. This code has been working, so I assume that our Toplink Essentials setup has been fairly lenient.
I've not been able to find any examples like this, so I'm guessing it's a bad practice. However, my books and searches haven't turned up anything warning against it either. Is there a better way to configure this field that doesn't run afoul of the specification?
Thanks

The temporal type is rarely required to be set as normally dates just work. So you could probably just remove it. It does seem rather short sighted of the Spec to not allow the two together.
The temporal type is really only required when your Java type and database type do not match, i.e. Calendar or util.Date in Java (which is a Date and Time) and DATE or TIME in the database (for the few databases that have a specific DATE / TIME type).

    How can I combine different pdf files in one?

    Sara,
    It is not working. I wish to decline in having the pdf pack. How can I give up this purchase? I definitely do not want the Adobe PDF Pack anymore.
    Who do I have to contact or what do I need to do to cancel this purchase?

    How can I combine different pdf files in one?
    created by Sara.Forsberg in Adobe PDF Pack - View the full discussion 
    Hi Flávia,
    Adobe PDF Pack is an online subscription--it definitely allows you to combine several files into one PDF file. For more information about PDF Pack, see Reliably Create PDFs, Convert PDFs, & Merge PDFs Online | Adobe PDF Pack. If you don't have the full version of Acrobat, this is a great solution for combining PDF files.
    However, if you're using Acrobat (not Adobe Reader), you combine files by following these steps:
    Open a PDF file that you want to add pages to.
    Click the Pages pane on the Tools panel (on the right side of the application).
    Click Insert From File, and choose the file that you want to combine with the PDF that you opened in step 1.
    Make any changes necessary in the Insert Pages dialog box--these settings determine where the new file will be inserted.
    Click OK.
    Please let me know how it goes.
    Best,
    Sara

  • I have photos I want to group together in one album, but can't do this because some may have the same number. How can I combine them all into one album?

    I have photos I want to group together in one album, but can't do this because some may have the same number. How can I combine them all into one album? I was trying to move several albums onto a USB drive and it stated all other files exist at this location.  They are pictures taken at different times and have the same number I guess.

    In iPhoto albums may contain photos with the same file name - iPhoto handles that just fine
    If you are exporting them to move somewhere else use the sequential file name feature of export to give each file a unique name

  • I have three different ipods with music on them and have had to replace our computer as it was in a fire. How can we combine the ipods into one ipod.

  • A music album is listed multiple times in my library but each listing only has a few songs in it-not the full listing.  How can I combine them into one album and get rid of other duplicate listings?

    Several music albums listed in my IPhone 5 music library are listed multiple times, but each one only has a portion of the songs listed.  How can I combine them to make one album?

    First....Thank you so much for your prompt reply.  I am sorry for not getting back to you regarding your suggestion-I had computer issues that just got resolved.  Also, this is my first foray into online chat rooms so I have a lot to learn to precisely state my issue!  I did as you suggested and all the songs list the same album when I go into each song's "get info".  However, I am not sure how to edit as you suggested. When I downloaded this album originally, for some reason it broke up into several albums each with different songs from the original album.  I am trying to consolidate them back into one album in my library.  I would greatly appreciate further assistance if you can.  Also, I do not use "the cloud" to store any data and would like a good source of info on how to do this.  Thanks so much for your patience!

  • I seem to have at least two, and maybe four, iCloud accounts, across my iPhone, my iPad and my MacBook Pro. Can I combine them into one iCloud account?

    I seem to have at least two, and maybe four, iCloud accounts, across my iPhone, my iPad and my MacBook Pro. Can I combine them into one iCloud account? I have been able to log into what appears to be three of the four iCloud accounts I have. Two of them seem to be remarkably similar, and one appears to be only for my MacBook.I think I know which one my iPhone is backing up to, as I successfully restored from a back-up last week. The fourth iCloud account I can't access via password or security questions. Any advice would be much appreciated.
    Thanks.
    Cheers,

    '''Try Firefox Safe Mode''' to see if the problem goes away. Safe Mode is a troubleshooting mode, which disables most add-ons.
    ''(If you're not using it, switch to the Default theme.)''
    * On Windows you can open Firefox 4.0+ in Safe Mode by holding the '''Shift''' key when you open the Firefox desktop or Start menu shortcut.
    * On Mac you can open Firefox 4.0+ in Safe Mode by holding the '''option''' key while starting Firefox.
    * On Linux you can open Firefox 4.0+ in Safe Mode by quitting Firefox and then going to your Terminal and running: firefox -safe-mode (you may need to specify the Firefox installation path e.g. /usr/lib/firefox)

    Hello Halfback71,
    Thanks for using Apple Support Communities.
    For more information on this, take a look at:
    Frequently asked questions about Apple ID
    http://support.apple.com/kb/ht5622
    I have multiple Apple IDs. Is there a way for me to merge them into a single Apple ID?
    Apple IDs cannot be merged. You should use your preferred Apple ID from now on, but you can still access your purchased items such as music, movies, or software using your other Apple IDs.
    If you are wondering how using multiple Apple IDs relate to iCloud, see Apple IDs and iCloud.
    Best of luck,
    Mario

  • HT204053 I have 2 Itunes accounts, one I don't use with money in the account, can I combine that money or account into the account I currently use?

    I have 2 Itunes accounts, one I don't use with money in the account, can I combine that money or account into the account I currently use?

    You can access, usually under the Apple (icon) menu in the main desktop
    window, note item with name "About this Mac" & click on that, to see more
    information about your computer, its OS X version, and other. The system
    version and build model are there. Do not post a serial number.
    If you are setting up Mail in a Mavericks OS X 10.9.x system, there often
    is access to information in the Help viewer from the main menu bar, or
    in an open mail application. If you have a Gmail or other account, that
    info is often on their home page where setup and help are located.
    The settings of each email account may vary according to their provider;
    so you would have to change your computer to accept them. An older
    link to a general look at that issue, change IMAP to POP, is covered here:
    https://discussions.apple.com/message/16770816#16770816
    While that may not answer your question, you could use the info in
    your Mac OS X system Help viewer and use its search; or maybe
    a Spotlight search to see an answer online.
    You have to learn some basic things in order to actually use these...
    and it helps to expand that so you won't have to pay for tech service
    on things you can do yourself in a few minutes, beyond easy stuff.
    Of course, you're hearing this from a guy with no ISP email, ever.
    So mine are web-mail only; & I never save email to a computer.
    PS: If you have a new Mac with an AppleCare plan, you may be able
    contact Support for help. Ask someone (for 90 days, or up to 3 years
    if the Plan was extended) there at AppleCare, for their guidance.

    Good luck & happy computing!

  • How can I combine two itunes accounts into one?

    How can I combine two itunes accounts into one?

    Items purchased from the iTunes Store are permanently associated with the account from which they were originally purchased.  Apple provides no way to change this.
    However, if you wish to put content from two accounts into a single iTunes library, you can easily do so.  Use the command File > Add File (or Folder) to Library.
