Application disappears.......

Hi guys, I could need some help here. I'm using Jdev/ADF 10.1.3.1 and Oracle AS 10.1.3.1
After deploying an ADF web-application (MY_APP) in a container (MY_CON) everything is fine. The application works. However.. sometimes when I do a redeploy, (which goes ok and without errors) MY_APP doesn't work anymore. In the em console, I can see MY_CON,but MY_APP isn't there anymore. When I look on the filesystem MY_CON is there and it contains MY_APP..............
What happened is a mistery, as is the solution........... The only thing I can do is deploy the application (not redelpoy because I cannot select it because it is invisible). Than it works OK again, and sometimes I can do redeploy. And after a while it goes upsidedown again.
Any suggestions or is this a bug ?

Try asking this on the OC4J forum to see if they have any insight:

  • Safari application-disappeared. & can't be found after download/install ...

    This morning, Safari application was no longer in the Applications Folder on my iMac. (Nor was FireFox!) Can't find it anywhere, even using 'Search'.
    So, I installed Safari from a previously downloaded .dmg/.pkg. Went through all the steps, and greeted with "Installation was successful!!!"
    However, the [supposedly] newly installed Safari application is nowhere to be found.
    I have been through various cycles of this, even downloading anew on MacBook and then dragging from MacBook to iMac. I have been careful to use the correct versions to match the Mac OS 10.6.2 that's on the iMac.
    I'm befuddled. Can't find a similar problem on the forum ...

    HI,
    *I have been careful to use the correct versions to match the Mac OS 10.6.2 that's on the iMac.*
    Absolutely.
    First, instead of using a .dmg Safari from a previously downloaded .dmg/.pkg... that might be a previous version of Safari, Go here and try downloading the newest version of Safari.
    http://www.apple.com/safari/download/
    Make sure and select Snow Leopard on the left. If after the installation, you still can't use Safari
    after you download and install Safari....
    When you have probems with applications disappearing, it's probably a good time to check the startup disk for errors.
    Insert your install disk and Restart, holding down the "C" key until grey Apple appears.
    Go to Installer menu and launch Disk Utility.
    Select your HDD (manufacturer ID) in the left panel.
    Select First Aid in the Main panel.
    *(Check S.M.A.R.T Status of HDD at the bottom of right panel. It should say: Verified)*
    Click Repair Disk on the bottom right.
    If DU reports disk does not need repairs quit DU and restart.
    If DU reports errors Repair again and again until DU reports disk is repaired.
    When you are finished with DU, from the Menu Bar, select Utilities/Startup Manager.
    Select your start up disk and click Restart
    While you have the Disk Utility window open, look at the bottom of the window. Where you see Capacity and Available. *Make sure there is always 10% to 15% free disk space*
    If the startup disk appears to be ok and there sufficient disk space, try booting in Safe Mode

    Hello, I synchronized my iPhones with iTunes, having a new laptop, I had to do this step. But instead of helping it, I lost many applications. All my good applications disappeared. How do I get them back? What I have to do? I bought those app!!!
    How is this possible? How can the iTunes eat what I bought and what for? To buy the applications again?! Geez!
    Tell me the solution. It must exist one!

    You can redownload you previously purchased apps for free as long as they are still available in the app store.  Be sure you are logged into the Apple ID in iTunes used to purchase them, then follow this guide: http://support.apple.com/kb/HT2519.

  • HT5973 the map application disappeared from my laptop , how can i get it back

    Is it in your Applications folder?  If so, you can drag it from there to your dock.

  • Excel application disappeared

    iMac running OSX 10.7.5
    Microsoft Office for Mac 2011
    Excel application gone and can't re-install because Apple ID invalid?
    After not using for a few weeks, by Excel application disappeared.  Application Icon still there, but error message appears.   Excel users files still there.  error message says: "Check the the developer to make sure Microsfot Excel works with this version of Mac OS X.  YOu may need to reinstall the application."
    I purchased Office for Mac 2011 and have a product ID.  I tried fixing the application but that didn't work, so the support info said to re-install.  When I try with my product code, it says that my product key is short 5 digits; it is 20 digits not 25.  However, when I look at the Product Key in Outlook, or Word, which are part of the Office Product I have, it says the product is licensed to me and shows a 20 digit product ID.  Why is my product key short 5 digits so that I cannot re-install Excel.  And why did my Excel application disappear?  I have automatic updates on, so it may have been an update.  I really can't pinpoint when my Excel application disappeared.

    I suggest you post your question on the Microsoft Mac Office forums as that's where the Office gurus hang out...

  • Downloaded Applications Disappear on iPod

    Hi, I recently bought an iPod touch and a Mac. Apparently either I don't completely understand how it works or there is a problem with my device. Every time I connect my iPod to my iTunes and sync everything (i have enabled syncing everything from music to applications). The applications disappear from the iPod although I can still see them in the "Applications" pane of my iTunes.
    Afterwards I go back to the AppStore and re-install the application. When I do it I get a message "You have already purchased this item to download it again press ok".
    The part which is annoying is that I don't want to re-download every-time the applications.
    Anyone has any idea why this happens and how to prevent it? On a similar note how can I install an application directly from iTunes to iPod touch, of course if it is possible? Any help would be appreciated.

    Make sure you have your applications set to sync as well in iTunes. Click on your device and then click on the tab marked Applications. Set iTunes to sync your apps - or it will remove them the next time you sync.

  • Why do my applications disappear?

    When I export my applications from my dev instance and I import them into the prod instance in without the build option they disappear from the list when I log into the prod database as the schema owner. Looking in the App Builder they don't show up.
    I only foind this when I wanted to rev the prod application and I couldn't find the current version in the list. It still works but I cannot see it to remove it.

    Hi
    The Application Express User’s Guide, section 'Exporting an Application and Related Files' mentions that while you are exporting an application:
    From Build Status Override, select one of the following:
    ■ Run Application Only - Developers can only run an application
    ■ Run and Build Application - Developers can both run and edit an application
    Selecting Run Application Only is an effective way to protect an application from
    modifications from other developers. Note that if you select Run Application
    Only you cannot set the argument p_trace to Yes.
    I hope this makes some sense for you.

  • Notes application disappeared from my iMac, how do I get it back?

    My notes application has disappeared from my iMac, how do I get it back?

    If you don't find it: start the iMac while holding the Alt(option) key: you get the EFI menu, choose the recovery disk, reinstall Lion: this leaves the user data untouched. But as always: backup.
    It will restore the system apps also.

  • Applications disappear when using external mouse

    Using windows 7 professional on a brand new T410 (2537-RZ5).
    Happens only when using an external mouse and mouse is stationary for random periods of time (seconds or minutes).
    Problem: all applications (internet explorer, office, etc) will suddenly disappear (sometimes only leaving outside border of application) to reveal desk top - does not matter which application i have open or whether there is one or multiple. Desktop color is correct but instead of solid color it has a diagonal ribbed effect to the color. Applications will reappear moment I move the mouse.
    Happens with variety of external mouse - does not happen if using laptop mousepad (i.e. no plug in). All latest windows and lenovo updates installed as far as I know but has not fixed bug.  Has happened again just while writing this message - quite frustrating.
    Please help if you can.

    I noticed a similar phenomenon and found that my mouse cursor was landing over the sensitive spot on the right side of the task bar which harbors the "Show Desktop" Aero feature.  Check it out.

  • Photo booth application disappear, photo booth application disappear

    photo booth application disappear

    Hello,
    Did it disappear just from the Dock maybe? Open the Applications folder & if there drag it to the Dock.
    Otherwise, Could be many things, we should start with this...
    "Try Disk Utility
    1. Insert the Mac OS X Install disc, then restart the computer while holding the C key.
    2. When your computer finishes starting up from the disc, choose Disk Utility from the Installer menu at the top of the screen. (In Mac OS X 10.4 or later, you must select your language first.)
    Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from the disc again to access Disk Utility.
    3. Click the First Aid tab.
    4. Select your Mac OS X volume.
    5. Click Repair. Disk Utility checks and repairs the disk."
    http://docs.info.apple.com/article.html?artnum=106214
    Then try a Safe Boot, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, reboot when it completes.
    (Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive.)

  • Application disappearing

    Hi,
    I'm not sure if anyone as experienced this or not... I'm running a mac lab at a high school (20 Intel iMacs with an Xserver running OSX Tiger Server).
    Intermitantly, the Photoshop applicatin icon within the Application folder disappears. The teachers and I do not suspect students are throwing away the application... it appears like it is somehow being turned into a hidden file.
    In one instance, the Photoshop.app file was missing, but a student was able to double click on a .psd file on the desktop and photoshop opened. Spotlight could not find the photoshop.app file though. This is what leads me to believe it is getting turned into a hidden file for some students.
    There are issues with our server, which has not been configured correctly. That will be taken care of shortly.
    Is this a permissions thing... or something else. I'm stumped right now. Any ideas would be appreciated.
    Cheers,
    Alan

    That's Exposé you're seeing.
    Go to "Apple Menu -> System Preferences -> Dashboard & Expose"
    Do you have one of the "Active Screen Corners" set to "Desktop"? When you move your mouse into that corner it triggers Exposé to clear your windows out of the way so you can access items on your desktop.

  • Downloaded applications disappear after restarting?

    Hi guys,
    I'm not sure if this is the best community to post this question. But here goes.
    I have several applications I bought online which seem to continually disappear on restart. At first I thought I imagined it, or I did something wrong. But now I can see it happens continually when I do a full shut down, at least on several applications.
    Specifically, I notice it happens with my VPN client and with Skype. A full search of my computer will only find the downloaded .dmg files for both applications. (It could be happening with more apps, but these are the ones I use frequently, so these are the ones I notice.)
    I just reinstall, but it isn't very convenient.
    Any idea why this would be happening and how to prevent it?
    Puzzled...
    Cheryl

    Welcome to Apple Support Communities
    Do you run the apps from the DMG file or you copy the apps to the Applications folder? You must copy them to Applications. If not, you will lose them because you are running them from their DMG

  • [SOLVED]Can't edit .desktop files with Gnome 3. Application disappears

    I've been trying to edit the desktop file for gimp so that I can run a custom command when it loads.
    Basically I want to run GTK_MODULES= gimp instead of just straight gimp, because the global menu doesn't work well with gimp and running it in this way forces gimp to use the normal menus.
    As soon as I edit the file, gimp disappears from my applications menu. If I click on the .desktop file through nautilus, it says there is a problem and it cannot run the application. I'm not sure how to open a .desktop file from the terminal, so I can't look for more specific error messages.
    I tried creating a script and pointing the desktop file to that instead, and I tried using GTK_MODULES= && gimp, but both give the same problem. As soon as I click save, it becomes unusable, only fixable by reinstalling gimp.
    Do you think it's possible to do what I'm wanting to do?
