Where are APEX images retrieved from in an n-tiered environmen?

Oracle XE DB 11gR2
Oracle APEX 4.1.1
Glassfish 3.1.2
Red Hat Linux 5.8
===========
I notice when using Glassfish as part of my APEX environment I am required to copy the images to an /i directory on the Glassfish server under the Glassfish domain.
The question arises --> When APEX needs to render an image, is the image retrieved from the database/database server or from the Glassfish web server?
Thank you.

If you're using Glassfish and the APEX Listener (or OHS) then images referenced using <tt>/i/</tt> / <tt>#IMAGE_PREFIX#</tt> are stored on and retrieved from the web server file system. If using EPG then they're stored on and retrieved from the database using the XMLDB repository.
If the image is referenced using <tt>#WORKSPACE_IMAGES#</tt>, <tt>#APP_IMAGES#</tt>, or declarative BLOBs then they're stored on and retrieved from the database.

  • Why are my images scrolling from outside the Page width?

    Why are my images scrolling from outside the Page width? I am positive i has all the settings correct, to have an image parallax scroll from the edge of the page into the page and out again. But the images are flying in from the browser width - not the page width. This is not the effect I am after.
    Any suggestions on how to fix this? Given the key position is only linked to the height, I can't for the life of me work out how to ensure the images start moving from a certain position onthe left and right of the page.
    Thanks

    I think the effect you are seeing is a result of how the lineHeight is set up. By default, the lineHeight will be calculated as 120% of the size of the largest thing on the line -- in your case, this is the inline graphic. This is designed to leave space between the line before and the line with the graphic. So it is taking the height of the graphic, multiplying by 120%, and making this the distance between the previous line and the line with the graphic. So the bigger the graphic, the bigger the space above the graphic. Normally this works well with text, but in this case you may want to get closer to "set solid". You can do this by setting the lineHeight to 100%. Or you may wish to leave a couple of percent for the descenders of the previous line. Or, another alternative that may work well for you if you really know exactly where you want the line set, you could measure the graphic, add on the number of extra pixels to leave for the descenders, and make the lineHeight a constant. So you could do something like this:
    <img lineHeight="104%" height="411"/>
    or this:
    <img lineHeight="423" height="411"/>
    Obviously you would still need to specify the source and any other parameters you want on the image.
    Note that if you are trying to fit a 200 pixel high graphic into a 200 pixel high container, you will hit the same problem -- in order to fit the graphic, the container will have to be slightly bigger than the graphic in order to fit the descenders on the last line. This is true even if the last line contains only the graphic, and no descenders (or text) at all.

  • Where are all my pics from my iphone that are suppose to have been backed up in icloud

    where are all my pics from my iphone that was suppose to be backed up to icloud?

    Welcome to the Apple Community.
    The difficulty in restoring iCloud data from a back up is that the back up is older than the current version on iCloud and anything that is restored gets removed again when an iCloud sync occurs.
    Ensure the device is connected to your local network.
    Start the restore from iCloud back up.
    Allow the devices settings to restore (watch for the confirmation of completion).
    As the apps begin to restore pull the connection to your router WAN port (the one that goes to the telephone point).
    Wait for the time out confirmation.
    Navigate to settings > iCloud and turn off contact syncing (keep contacts when prompted).
    Reconnect the router to the internet and let the restore process complete.
    Delete any iCloud contacts from iCloud.com on a computer.
    Navigate to settings > iCloud and turn on contact syncing (merge contacts when prompted).
    May I suggest that you carry out a back up to iTunes before you try anything, that way should things become even worse, you can at least restore back to where you are now.

  • Where are the Image Properties located?

    Where are the Image Properties located? Recently watched a tutorial that suggested right clicking an image to see the Image Properties window. However, I am not seeing it. I am looking to add Image descriptions for better SEO. Thank you

    Hello,
    Is that image used as a fill in a rectangle ?
    If you right click in a Image frame you will the option for image properties. look at the screnshot.
    If you right click on a recangle that has an image used as a fill then you will not the option for image properties. look at the screnshot.
    If there is anyother scenario you are talking about please let me know and i will look in to it.

  • How to cache images retrieved from MDM on Java WebAS

    Hello Colleagues,
    We have a scenario where we are trying to retrieve image records from the MDM using Java APis. Instead of hitting the DB everytime, is there a way to implement caching? For instance, is it possible to cache the images on the java WebAS and return the path of the images instead of returning the byte stream everytime?
    Thanks and Regards,
    Nisha
    Edited by: Nisha NC on Sep 1, 2009 7:35 AM

    Hi Nisha,
    You can use the Class ObjectCache from the Java API.

  • Where are the Image Settings?

    In Adobe's Bridge Reference, it says, "Here are some tips for automating the processing of camera raw image files:
    When you record an action, first select Image Settings from the Camera Raw Settings menu [icon appears here] in the Camera Raw dialog box. In this way, the settings particular to each image (from the Camera Raw database or sidecar XMP files) are used to play back the action."
    Problem is, I cannot find the Camera Raw Settings menu anywhere in the Camera Raw dialog box, and I cannot find anywhere in the documentation where it tells you how to do what they're recommending here. I'm confused as to whether the action recording takes place in Photoshop (most likely), Bridge, Camera Raw, or the Image Processor. I was under the impression that, of these four, actions can only be created in Photoshop, but now I'm not so sure, since this paragraph says that while the action is being recorded it has to be selected from the Camera Raw dialog box. WHERE DOES ONE FIND "Image Settings" IN THE CAMERA RAW DIALOG BOX?
    Edit: Actually, I found the Image Settings selection, but it is still unclear how I can incorporate it into an action. Can I invoke the Camera Raw dialog box while recording an action? if so, how?

    Record an Action after opening a file into Photoshop, so the Action contains no Open command but it does contain Save and Close.
    Run the Action in a Batch with disabled 'Override Action "Open" Commands' and enabled 'Override Action "Save As" Commands'.

  • Where are the images stored after migration

    I'm totally lost after migrating my pictures from iPhotos.app to Photos.app...
    From an article from Apple, (see below) there is no duplication of the library even if it looks like (when you look at the GB). So i understand that there is a kind of link or alias for each picture. But i would like to know where the original ones are (imposible to know looking at the finder because both libraries show strangely a lot of GB.
    So I tried different options to understand. If I delete an event in the iPhoto library and definitely trash it, these pictures are still in Photos. And if I delete some pictures in Photos.app definitely (deleting definitely from File Menu > Show Recently Deleted) these pictures are still in iPhoto !!! So where are the real pictures ??? In which library? Somewhere else? Why the two libraries are showing all these Gb and it does'n't correspond to the capacity storage of my hard disk...
    I really don't understand how it works... Any help would be very appreciated.
    Article from Apple :
    Photos saves disk space by sharing images with your iPhoto or Aperture libraries
    Learn how Photos stores images when you migrate your iPhoto or Aperture library and saves disk space by sharing images.
    When you migrate a photo library from iPhoto or Aperture, the Photos app creates a new library structure but doesn't duplicate your images. Instead, Photos saves disk space by creating links to the original and preview versions of your images.When Finder reports the file size of your Photos library, it includes all your originals and previews. It may look like your remaining iPhoto or Aperture library is taking up twice the space on your hard drive, but it isn't—your images exist only in one location, even though you may have more than one photo library.After you migrate your iPhoto or Aperture library to Photos, you might feel tempted to delete your original iPhoto or Aperture library. Because the migrated library takes little additional space, you don't need to delete the original library.

    They're in both libraries; a hard link to a file is indistinguishable from the original file, and either one can be deleted without affecting the other.

  • Saving MSW or TextEdit docs to iCloud - where are they for retrieval?

    It does not help being ignorant about iCloud, but I am.
    I was saving a transcript in TextEdit when the iCloud prompt screen appeared indicating I could save it there. Because I have no idea where it can be retrieved, I saved it as normal, which is not a problem for me whatsover because I have a meticulously operated IMac with specific folders to save all my documents for various organizations including personal files Something I have done for over 10 years without any problems when it comes to retrieving files for later use. My IMac and MacBook are not lacking storage space. Have lots to spare.
    Ancient users like me from the past century may not be catching onto iCloud like I should. I went to a Mountain Lion workshop but it was mostly an overview, no specifics. I found out that Apple has 3 new programs that simulate MSW Office documents. I have a sense that MSW Office files are not compatible with iCloud storage.
    Okay! I need help to better understand saving files to iCloud and where on my system is iCloud to retrieve them? And, upon doing so, when I go to my MacBook, can I retrieve the same files on this device?
    Dummy #1, for sure! Your patience and understanding will be most appreciated. Look forward to your assistance.

    It will have been saved in your Home/Library/Mobile Documents/com~apple~TestEdit/Documents folder.
    But remember:
    In Lion and Mountain Lion that Library folder is now invisible. To make it permanently visible enter the following in the Terminal application window: chflags nohidden ~/Library and hit the Enter button - 10.7: Un-hide the User Library folder.

  • Where are my calendar entries from 2011?

    I can no longer access any calendar entries from 2011.  They are GONE.  As a test, I made another entry in the December 2011 calendar, and within five seconds, it disappeared!  Where are my entires for all of last year?  How do I get them back?  I do not have a calendar program on my PC, and I never set any preferences when I installed Icloud, and I cannot access calendars in Icloud without installing Outlook.  I dont want Outlook.  I want my data back from the cloud!  HELP!

    You need to find out how the Google calendar application imports calendars from Macs. As for the Calendar itself you can export the calendar to a file. The Google calendar should be able to Import that file.

  • IOS7 mail search results appear to be random by date also where are the search parameters, from to etc..? help!

    Mail search returns results by random date. Where are the mail search parameters, from,to,etc?

    This is really annoying. Mail search on iOS 7 never worked, either on iPhone
    4S or on iPad.
    Search results are not sorted in any perceivable order. I get totally random results, with messages dating 4 years back jumping to yesterday and so on.
    I have never seen Apple to respond to this issue with earnest feedback, and users are often dismissed.
    I used to have to resort to my Macbook Pro to get decent results, but due to the many mail app problems on OSX, I do not rely on it anymore.
    Can Apple please give feedback to this search issue on the IOS devices? It is really, REALLY crippling.

  • Where are recorded the data from the app "the stickies" on a macbook pro retina?

    Hi !
    I lost all my stickies. I don't know why but one day they dissapeared. Where are they located on the mac? So maybe I can recover them with time machine.

    I know the location of the information, but I'm not sure yet how to get to it from Time Machine. But here is the path anyhow. I'll let you know if I find anything else.
    ~/Library/StickiesDatabase
    to get there open Finder.
    Click the Go menu in the top menu bar.
    Hold the Option key on the keyboard, and Library will appear in the menu. Click on it.
    Near the bottom you'll see the StickiesDatabase, it is one of the only files there that is not a folder.

  • Where are the "Organizer" files from PSE 11 stored on a mac?

    I have lost all my albums from my PSE 11 (Mac, using Mountain Lion) -- the album names are there but not the files within the albums.  I tried the reconnect and the computer just went crazy.  Seeing as I did a Time Machine back up of all my files yesterday when the Albums were all present and working, I thought maybe I could just drag them over from the backup to my hard drive - however I can't find where the organizer stores these albums.  I did find a folder inside Adobe that says "organizer" and inside that there's another folder that says "11.0" but even on my oldest Time Machine back up, that folder is empty - so obviously it's not the correct one.  Anyone have suggestions where I could find the albums within Time Machine?

    thanks for that info - I didn't know that about finding the library in 10.8 (obviously) -- and I was able to find the library and navigate my way to my catalog -- it looks like it's fine - in fact I was able to run the catalog manage, repair, optimize etc and it says everything is fine - however when I restart PSE and the organizer, my photos are still all missing from the albums.
    too late now, but tomorrow, I'll try to see if I can find that catalog in yesterday's time machine back up -- do you know if that's possible?
    I'm not really sure what happened - because when I started out today, things seemed to be working fine - it wasn't until I tried to add a new album that I discovered the issue with the missing photos.
    truthfully I don't care about the albums - they would be easy to reconstruct -- but I'd like to be able to delete the names of them and start again - but I can't seem to find info on how to do that.  the book I have doesn't give that basic kind of info - more info on using the tools to be creative.
    thanks so much for your help - you're very knowledgeable about PSE!!! and Mountain Lion which I've only been using for a few months.
    cheers, Lynne

  • Where are RUG Downloads stored from ZLM Server

    In a ZLM environment used for patching SLES 10 and OES for Linux servers, if I run "rug -d" to just download new patches, where are the files actually getting downloaded to?
    Sean

    Sean,
    by default they are stored in /var/cache/zmd/web before they are installed.
    So I think you will find it there in. That cache directory can be set as a rug parameter. I guess you will not have modified it, but you can check it using this command:
    # rug get cache-directory

    If you want to stick with adjusting the scale you can do this two ways. Edit the value graph or edit the speed graph.
    The problem is that a camera move, a zoom or a dolly in, is not linear and scale is. This means the graphs are not a good representation of what you'll see visually. This makes them hard to use. At a constant rate for scale the appearance is that the increase in size slows down to closer you get to the final value. In other words, as you scale an object up at a constant rate, the visual appearance is a gradual slowing.
    A speed graph edited to look like this gives the appearance of a constant rate scale of the layer when you expect an acceleration at the end. There's just not enough granularity in the graph editor or enough control to predictably achieve the results you want.
    You'll have better luck editing the value graph to look something like this:
    While this looks extreme, you will get closer to achieving the results you want using the value graph. Once again, the amount of control and the resolution of the graph combined with the visual tomfoolery that scaling an object brings with it makes this a difficult way to achieve predictable results.
    You select the graph you'll edit by clicking on the second icon from the left.
    As I said before, you'll have much better luck getting the look you want if you make the layer 3D and move a camera toward it.
