This question may sound stupid, but...

I downloaded jbuilder x enterprise edition, however, it does not recognize classes such as
javax.ejb.MessageDrivenBean
javax.ejb.MessageDrivenContext
javax.jms.Message
javax.jms.MessageListener
javax.jms.ObjectMessage
do I need to include something else apart from the standard library? where to get it ?
Thanks a lot~~

Check the manual or the program's settings to make sure that it will import the extended java classes - javax libraries.
Your project settings might also fall under this pit as well, make sure that the javax libraries are in the complier/library path.

  • This may sound stupid but for some reason I can no longer use the return button after typing in a url to go to that site. Does anyone know how to fix this?

    For some reason this stopped working on firefox a week or so ago. I have tried to uninstall and install firefox again but the problem still persists. I've tried both chrome and explorer and they don't seem to have this problem.
    I'd hate to stop using firefox but this so annoying that in less i can fix it, i'll have to change my browser!

    Hi larryhall,
    I'd try starting Firefox in [[Safe Mode]]. If you don't have the issue while all of your add-ons, extensions, and themes are disabled, you can try adding them back in one by one until you find the culprit. You should look at the [https://support.mozilla.org/en-US/kb/Troubleshooting-extensions-themes Extensions and Themes troubleshooting guide ] and the [[Troubleshooting plugins]] article as well.
    Hopefully this helps!

  • I am currently using iplanet 4.1 on a solaris box.  This is my first time using Iplant so this question my sound trivial but I am not sure how to figure it out.

    I am getting the following error when I try to restart the server. Can anyone help?
    Status:
    [https-verity-dev]: start failed. (2: unknown early startup error)
    [https-verity-dev]: conf_init: Error running init function load-modules: dlopen of /usr/local/netscape/server4/bin/https/lib/libNSServletPlugin.so failed (ld.so.1: ns-httpd: fatal: libjvm.so: open failed: No such file or directory)

    Error
    An error occurred during startup.
    The server https-verity-dev was not started. Currently our server is down, it is only a dev box but we are currently tryhing to test so any help would be greatly appreciated.
    Thank you

    Hi,
    U did not mention in which version of Solaris u r installing IWS 4.1
    Try these steps:
    (1)Have u chosen the option to install jdk with IWS setup or u manually added the classpath after installation?
    (2)Make sure you have the latest operating system patches installed. You can download them from Sun's web site.
    (3)It may also be that the environment variable LD_LIBRARY_PATH isn't set. It should probably be set to "/usr/lib:/usr/ucblib". Make sure it is set correctly, and try the installation again.
    then try to start the server again

  • HT4864 Thank you! This may sound lame but are these instructions for the blackberry? I'm receiving iCloud emails without problems on my MacBook Pro and I'd rather not mess w/ settings there.

    You don't need to start a new thread to continue a conversation, you can just tack onto the original one. The settings I referred you to are for the Blackberry, since that's the device which is not receiving mail: anything which is working can be left alone.

  • I know this is going to sound stupid but I can't seem to set up my email as an iCloud email account. I want to eliminate my aol account and transfer everything to iCloud with an iCloud email. How do I do this.

    I know this is going to sound stupid but I can't seem to set up my email as an iCloud email account. I want to eliminate my aol account and transfer everything to iCloud with an iCloud email. How do I do this.

    If your Mac is running OS X 10.7.5 or higher, you first have to go to System Preferences>iCloud, sign in with your Apple ID to create your account, then check Mail.  This will automatically add an iCloud email account.
    To transfer your AOL mail, you need to drag and drop them into the same folder in the iCloud account.  If you have any folders in your AOL mail, you would need to create folders by the same name in the iCloud account, then open each folder, select all the mail in the folder and drag and drop them on the folder by the same name in your iCloud account.  (To create a folder in the iCloud account, click the "+" at the bottom of your folder list, choose Create Mailbox, choose iCloud as the location and give it a name.)

  • This may sound silly but can anyone tell me if facetime is done through wifii or is it charged as a long distance from canada to us

    this may sound silly but can anywone tell be if facetime is wifi or a long distance charge?

    FaceTime is NEVER charged. It is basically going through the internet, as if you were watching a YouTube video, it just takes data. You probably have a data limit through your wireless provider, for example, I can only use 3Gb of data per month on my iPhone 5 through AT&T.
    If you use Wi-Fi, you will NOT be charged for data (unless your internet provider has a cap on the amount of data you can use).
    If you do facetime over cellular data, you just have to watch your data usage. You can watch your data usage in Settings > General > Usage. AT&T, Verizon, and Sprint all offer free apps you can use to monitor your data usage (among many other things, like pay your wireless bill, etc.).

  • This may sound silly but where do i find my attachments after i download them

    may sound silly but where do i find my attachments after i download them

    What attachments are you talking about? Do you mean the files and or photos you receive in emails?
    Mail loads the attachments and they should appear in the body of the email. Some can be viewed by tapping on them. If you have a compatible app you can save them to the appropriate app. An example might be a Word document. If you have an app that edits Word docs like Pages or some other app, tapping on the attachment will bring up a choice to open in Pages.

  • It sounds stupid but I cannot figure out how to create a TOC

    It sounds stupid but I cannot figure out how to create a TOC

    You'll find some good video tutorials with these Google searches:
    (search Google for these terms without quotes)
    * indesign paragraph styles tutorial
    * indesign table of contents tutorial
    * InDesign paragraph styles in table of contents tutorial
    The simple principle is: InDesign creates a TOC by "pulling out" heading paragraphs from your document. To help it know which paragraphs are the headings you want in the TOC, you need to create paragraph styles, and apply them to the heading paragraphs. Then, when you perform Layout > Table of Contents, you choose the heading paragraph styles, and run the process.
    It may be daunting if you've never done anything like this. But, if you've done it in MS Word or other word processor, the principle is the same - make the headings identifiable in some way, so the software can extract them.
    Look at the video tutorials, create a heading paragraph style, create a TOC, and let us know the result.
    If your document is one of several that are gathered into an InDesign book, search Google for terms like "working with InDesign books tutorial," and "InDesign book table of  contents tutorial," without quotes.
    It would help if you can provide screen shots of your result. Search Google for terms like "how to create a screen shot on mac," or "how to create a screen sot on windows," without quotes. It also helps to display hidden characters when you make the screen shots. Search Google for terms like "how to display InDesign hidden characters," without quotes. Search Google for terms like "how to post a screen shot on an adobe user forum," without quotes.

  • This may sound dumb, but is there an app or a monthly subscription to carry wi-fi or internet connection. so i dont lose connection when i leave my house. want internet connection at all time

    I have an ipod touch 5th gen.  storage capacity is 27.9 / 23.3 available.  IOS 7.1.2    model # ME978LL/A.   My question is, now this may sound dumb. But i was wanting to know if there is a app or a monthly subscription to have internet connection or wi-fi at all times instead of just shutting my ipod off very few apps work without internet connection almost dosen't seem worth 300 dollars.  THANK YOU FOR YOUR INFO.

    Your internet connection depends on access to a wifi network. When you leave your house you go out of range of your own network, so the only way to connect is to find a free or paid public wi-fi service in the location you are in at the time; the alternative is to use your iPhone for what is called 'tethering' (providing a wifi signal you iPod can connect to) but it you have an iPhone you would want to use that anyway (and many service providers don't allow it - in any case it comes expensive as you are using a mobile data connection).

  • This may sound stupid...

    This may sound extremely stupid and I completely understand how many of you are frustrated about the whole Aluminum iMac freezing issue but today as I was using iChat and Safari everything on the computer seemed to freeze, I couldn't click on anything or scroll but my mouse curser still worked - I use a wireless might mouse. So I reset the mouse by turning it off and then let it synch back up with the computer again. Then everything was fine - I don't want to sound arrogant and naive but if you use a mighty mouse (wired/wireless) unplug or turn it off and see if thats the problem.

    You can return it at the place you got it. If you bought it at an Apple Store, their return policy is 14 days.

  • TS2755 why have we deleted all saved messages and the iphone 4s sitll says 6GB is devoted to messages. I have seen this question asked numerous times but Apple seems to be ignoring it.

    Can't update the Iphone operating system because 6.8 GB is devoted to messages despite the fact that all messages have been deleted.  Did a reset, back up and restore, still 6.8 GB allocated to messages.
    The local Verizon store, which is a company store, just said to back up and restore with itunes, but that didn't work.
    I have seen this question asked on support community blogs and various people have suggested different solutions, some very technical that involve changing settings on the backups saved on Itues files on your PC and lots of posts from people saying it worked for me, but many others saying no, that didnn't work.  
    It seem utterly irresponsible for Apple not to publish a fix that actually works.  With what you have to pay for these phones, it's ridiculous.

  • This may sound stupid! but is the iCal a different calendar to the iCloud Calendar?

    My iphone and Mac do not seem to sync properly - although some diary entries do sync, the actual number and names of calendars do not match on each device. Im really confused by it all! Also is Contacts different to Address Book?????? Same problem.

    Hi jojoscorpio,
    I have had the same problem when I recently bought a new iPhone. With me it helped to completely turning off and on iCloud on both my iPhone and Mac.
    You can do this on your Mac by going to settings - internet and wireless - iCloud and then turning off everything you see.
    You can do this on your iPhone by going to settings - iCloud and then turning off everything you see.
    Afterwards you close both applications and put them back on.
    Good luck!

  • I know this may sound silly but i'm scared

    ok my parents got me my macbook about 2 months ago and everything's ok until about now. mac's are suppose to be silent computers right? (i've used macs for years but never go into the technical aspect) now my laptop has been whirring a lot.
    i know it may not sound like much but it's the same whirring noise my dad's old mac used to make before it froze. and i'm scared of my laptop freezing on me unexpectedly. it tends to make this noise while i'm playing the sims 2 (btw while i was installing the sims 2, it warned me that my processor was under the required 500 whatever-the-units-are ,i forgot, but i clicked ok and play the sims 2 fine) but would stop after some time. now it makes it while i'm doing something simple like using safari or yahoo messenger.
    i think it should help to mention that i do quite a bit of downloading. i downloaded a ton of widgets the other day and sometimes get music and some tv shows (and on the itunes store too) and i use limewire sometimes but my laptop whirrs when i do.
    so any diagnosis? should i uninstall the sims 2? stop downloading? or use my laptop like normal and hope the whirring wont lead to things to come?
    i'm really worried...

    That widget I posted will tell you the fan speed, and internal temperatures, and what is chewing up the machine, and . . .
    But not as much detail about running apps as Activity Monitor. Good to use both.

  • This is going to sound stupid, but how do I move the gnome3 dock?

    I would Like to use the one from gnome-shell-extension-dock, but I can't for the life of me move the original one or remove it for that matter.
    How do I go about doing this. This is the first time I've actually been able to get Gnome 3 and Gnome-shell working decently without breaking my themes (Apparently Adawaita uses the same general colors as the GTK2 theme it uses does, so I just copied the gtk3.0 and metacity-1 folders from said theme into all my Murrina themes and now everything looks good)
    Also, sometimes Gnome-shell crashes just out of the blue, or at least the window manager does. I can't figure out why it does this, but I suspect it might be because compiz-fusion-icon keeps loading.
    EDIT: I seem to have fixed the sound issues with my headphones by switching it over to analog stereo duplex when I'm running shell.

    Don't believe so. You can always install Docky or Avant Window Navigator if you like. I liked Gnome3 for a while but got sick of repeatedly moving my mouse up to the corner to make stuff I commonly use visible. I hated the way workspaces are done too. Not sure why they made these decisions but for better or worse they are here. I've moved on to KDE and Openbox where I actually have some control over things.
    I liked Gnome3 for a while, I have to admit. In the end I was just too restricted. Lot's of extensions for it coming out though which might help with this stuff. You could just get rid of gnome-shell though and use another dock of your choice.
    That's the problem though, I think I'm actually beginning to like old g-shell. Funny as I used to bash the you know what out of it, but once you find some workarounds and make stuff look good, it's not all that bad.
    Oh and I found out what kept crashing Gnome Shell..it was when I was switching themes, but only with certain ones. Deleted those and now it works.
    ....And now my dock seems to display correctly again -.- . Seems it only happens when I boot gnome-shell initially.
    It's probably going to be one of those odd quirks I'll just have to live with until Gnome-shell is patched or updated to allow resizing and moving.

  • This may sound goofy but how can i delete ALL the items in my shopping cart

    i would really like to know how to do this so i can start from scratch i printed off all that was in it so i can refer back to it but i want it all gone at once just all of it clicking the x is just too much for me to sit for minutes on end / hours to do just too much in there.

    Try this instead:
    Drive Partition and Format
    1. Open Disk Utility in your Utilities folder.
    2. Select the backup volume from the left side list. Click on the Erase tab in the DU main window.
    3. Set the format type to Mac OS Extended (Journaled.)
    4. Click on the Erase button.
    You will need to reconfigure Time Machine preferences for the backup.
    FYI: Never remove Time Machine backup data except through the Time Machine application. If you aren't sure about using Time Machine then visit Pondini's Time Machine FAQ for help with all things related to Time Machine.
