OC4J creating StatelessSessionBeanWrapper files.  What are they?

When I start OC4J, it creates a bunch of StatelessSessionBeanWrapper.java and .class files in the directory I start OC4J in. The files arn't even in the OC4J directory.
What are these files?
Is there a way I can make them go to their OC4J directory?
thanks,
Isaac

Hi,
We have the stateless sessionbean exposed as webservices
Once the server is restarted, we are getting a ClassCastException
java.lang.ClassCastException: IShoppingDiscounts_StatelessSessionBeanWrapper7
We have to redeploy our ejb application, to get rid of the ClassCastException.
After redeploying the service everything works fine.Any clue on avoiding this situation.
Thanks
- Gana.

  • Today, I randomly happened to have less than 1GB of hard drive space left. I found very large "frame" files, what are they?

    I found very large "frame" files, what are they & can I delete them? (See screenshot). I'm a (17 today)-year-old film-maker and can't edit in FCP X anymore because I "don't have enough space". Every time I try to delete one, another identical file creates itself...
    If that can help: I just upgraded to FCP 10.0.4 and every time I launch it it asks to convert my current projects (I know it would do it at least once) and I accept, but everytime I have to get it done AGAIN. My computer is slower than ever and I have a deadline this friday
    I also just upgraded to Mac OS X 10.7.4, and the problem hasn't been here for long, so it may be linked...
    Please help me!
    Alex

    The first thing you should do is to back up your personal data. It is possible that your hard drive is failing. If you are using Time Machine, that part is already done.
    Then, I think it would be easiest to reformat the drive and restore. If you ARE using Time Machine, you can start up from your Leopard installation disc. At the first Installer screen, go up to the menu bar, and from the Utilities menu, first select to run Disk Utility. Completely erase the internal drive using the Erase tab; make sure you have the internal DRIVE (not the volume) selected in the sidebar, and make sure you are NOT erasing your Time Machine drive by mistake. After erasing, quit Disk Utility, and select the command to restore from backup from the same Utilities menu. Using that Time Machine volume restore utility, you can restore it to a time and date immediately before you went on vacation, when things were working.
    If you are not using Time Machine, you can erase and reinstall the OS (after you have backed up your personal data). After restarting from the new installation and installing all the updates using Software Update, you can restore your personal data from the backup you just made.

  • Desktop null files - What are they?

    I have recently starting getting a file in my home folder repeatly.  The file name is
    Desktop-1.(null)
    and the next one will be the same, but 2, 3, etc.  What are they?  I throw them out and later more get created.
    Thanks
    I'm on OS X 10.8.2

    I've had them too. They are PDF files that I downloaded from the internet (and perhaps they failed or something?). Anyway, check it out: change their extension from .(null) to .pdf and you'll be able to read them and decide what to do with them.

  • "recovered"files. what are they?

    I have 25,000 photos in a library. Also there are thousands of photos in a folder called "Recovered Folder" of which they show as ALBUMS. I have checked many of them, and they seem to be duplicates of the photos in PROJECTS.  I have tried to find out what they are, and why they are present, but only find a relationship to Vaults, which I do not use.
    a)what are they and where did they come from?
    b) can I get rid f them withut loosing any of my photos?
    Thank you
    Asuch

    a) A "recovered" folder is akind of "Lost & Found" place.  When you repair an Aperure library, upgrade it, or rebuild it, Aperture will place there any items found in the Aperture library, that are no longer tied to versions in your projects. 
    b) That is hard to tell, without seeing your library. Frequently these items are just items that should have been trashed, but the Trash did not empty properly. Then you can trash them. But sometimes versions are losing there connection to the originals, but you may not notice it immediately, until you try to edit the version or to export it. And then you will need the recovered item. The safest cause of action would be to create a backup copy of your library as it is now.   Then look at your recovered items and try to identify the original in its project, If you are sure, that you have a working copy of the recovered item, delete it.

  • .pk and .pkf files (aka peak files) - What are they?

    Peak files - ones with .pk and .pkf extensions - are files that Audition creates upon first opening an audio file, and they contain information about the way it's displayed on the screen. After you've worked on a file, saving the peak data as well as the file means that the next time Audition opens it, it can do so a lot faster - simply because it doesn't have to create all that visual data again.
    By default, Audition saves peak files automatically for wav files, but it can't create them for other types. The reason for this is that it doesn't need them for those file types, as they can't be opened natively in Audition anyway; they have to be decoded into wav files first.
    The difference between older .pk files and newer .pkf files (the ones that Audition CS5.5 uses) is that the .pkf ones contain Floating Point data. This means that unlike .pk files, they can display information about files where the signal exceeds 0dB. This means that if you do a mixdown where the levels are rather hot, you can display the levels correctly in Edit View by zooming the vertical display out. If you replay the file at this level though, it will distort, so you still have to normalize your resulting file so that the peaks don't exceed 0dB before making, say, a CD from it, a 16-bit integer copy, or any sort of compressed file.
    Because of this fundamental difference though, .pk files and .pkf files aren't interchangable. So a .pkf file created with Audition CS5.5 won't work with any previous version. What will happen if you open one of these files in, say Audition 3 is that a new .pk file will be created, and stored alongside the .pkf one. And similarly, a .pk file from a previous version will be ignored if an older file is opened in Audition CS5.5 - it will create a new .pkf file for it.
    Both .pk and .pkf files are normally hidden file types, so you won't see them in your files folder unless you've set it to display hidden files. It doesn't matter in the slightest if one gets deleted accidentally - which ever version of Audition you are using will recreate the appropriate one automatically. The only difference you will notice is that it takes longer to open the file. Not much of a problem with a very short one, but if your file is an hour long, the difference is significant.

    In the light of a few recent posts about this, I should also add that you shouldn't try to open .pk or .pkf files on their own. By default, the file extensions aren't associated with Audition as far as the OS is concerned - they don't need to be, because Audition will look for the peak file associated with a wav file when it opens it, and the OS doesn't get involved in the organisation of this. And, on top of that, Audition doesn't regard the mere existence of a .pk or .pkf file as an excuse for opening. Why should it? It knows  that there's no audio in it!
    So basically - You Can't Open .pk or .pkf Files.

  • Two questions; ejb tmp jar files what are they? and web deployment procedur

    I am a bit confused about the deployment of WAR files or web application for ejbs.
    Well, in the tutoral there are not much ejb examples with web applications. the only example is the converter with one index.jsp. And there is the Duke banks.
    In the converter as far as i understand to deploy the converter war file we only need to specify the context root
    but when deploying the duk bank WAR file there a alot of stuff to be done alias, context parameter, url patterns and so on
    would someone explain to me what are the main steps for a web application deployment?
    i appreciate your assistance
    thanks

    what are these tmp.... files?These temp files are created by the App Server. Not sure why they are there...

  • Adjunct files - what are they?

    what are the automatically created files iPhotolock.data, iPhoto.ipspot, and iPhoto.db?
    what do they do? if i delete them while trying to reconstruct the nonfunctioning iPhotolibrary associated with them, will I cause trouble?

    j in seattle
    These are all part of the iPhoto Library installation. It is strongly advised that you do not move, change or in anyway alter things in the iPhoto Library Folder as this can cause the application to fail and even lead to data loss
    If you're trying to reconstruct a non functioning library for v5 of iPhoto see this article:

  • Optional Install in Snow Leopard -- "Pod Support" files -- What are they?

    I posted the below in the Snow Leopard Installation forum but got no answer. (see http://discussions.apple.com/thread.jspa?messageID=10710170#10710170 ). It was suggested that I post the same question here:
    In Snow Leopard, one of the optional files you can install are simply called "iPod Support" files.
    iTunes supports iPods etc.
    What are these optional "iPod Support" files?
    Why would someone install them?
    P.S. I don't think the "iPod Support" files have anything to do with syncing. If you choose NOT to install the "iPod Support" files during install, you still can sync your iPod with iTunes.
    These files are a mystery to me. Does anyone have an answer?

    Well I thought this was the right forum to ask the question. My question relates to an OPTION available when you install Snow Leopard.
    I don't think the "iPod Support" files have anything to do with syncing. If you choose NOT to install the "iPod Support" files during install, you still can sync your iPod with iTunes.

  • I have a long list of gibberish files, in Preferences, in my Library. What are they? How did they get there? Can I delete them?

    I have a long list of gibberish files, in Preferences, in my Library. What are they? How did they get there? Can I delete them without causing a problem?

    Here is one thing I found googling for WebEx:
    http://www.webex.com/why-webex/overview.html
    (The x64 would most likely mean 64 bit). It may be a Windows based application/plugin, but since I had never heard of either, I'm only guessing there. If you do a search systemwide for it and don't find it plus don't know why it's there, I'd say throw it in the trash (don't empty it yet - make a note of the file path just in case you do have something installed that needs it so you can move it back).
    Glad to hear it's not a torrent; some people use those not realizing that quite often there is a price to pay for downloading stuff for free that costs money elsewhere - the software packages quite often include little "add-ons" = malware which you really don't want.

  • Can adobe patch files be deleted what are they whay do they take up so much space

    Can adobe patch files be deleted? What are they and why does it take up so much space?

    sweetboo5
    If you are using Premiere Elements 9 Mac, then the next thing to do is to get details on what you mean by "patch files".
    There are no "patch files" as you describe. There is a Premiere Elements 9.0.1 Update that needs to be used with the program. That you install and do not uninstall for best performance of the product.
    What I am wondering is this. Do you mean by patch files and the description that you give Scratch Files?
    If so, then you are looking at preview files and conformed audio and video files.
    I am strictly an Elements Windows person so you will have to help me translate my Premiere Elements 9.0/9.0.1 Windows instructions into meaningful ones for you as it relates to file location.
    Under Edit Menu/Preferences/Scratch Disk, where do you have Video Previews and Audio Previews directed. At that location, you should be able to delete these files. They are automatically generated when you render Timeline content. The consequence of deletion is that you will need to render again content in the project from which they came (if that project still exists). Go to the location shown and delete.
    Then look to see where the Media Cache is directed. Those are conformed audio and video files (cfa and pek). They can be deleted and will be regenerated by the program if and when needed. Go to the location shown and delete.
    Then look to Edit Menu/Preferences/Media and the Media Cache Database. That is targeting conformed video files (.mcdb file extension). They can be deleted and will be regenerated by the program if and when needed. You can click on the Clean button there to get rid of them instead of following the path to them as shown in the Media Cache Database area.
    Do not delete any source media that went into projects after they were saved closed.
    Please review the above and do not hesitate to ask if you need clarification on anything that I have written.
    If none of the above applies to your question, then please more details.
    Thanks.

  • .itc files.  What are they?

    Can someone tell me what the .itc files are that are stored in the Album Artwork Cache folder on the hard disk in the iTunes folder? I came across some while I was doing a search, thought they were something else and started to delete them. Now I have a bunch of them sitting in my trash and I'm not sure if I should permanently delete them or not. At the same time, I can't figure out which ones go in which folders if I were to try and put them back to their original location. If I delete them, will they be automatically generated again? Are they necessary for something? What are they?

    They are definitely downloaded pic files. I say pic files, because instead of album artwork, they are actually small picture files of classical music composers pulled from various sites on the web.
    I used "album artwork" in a loose sense inasmuch that you could put a photo of your dog into iTunes and call it album artwork.
    Anyway, I guess my next question is what to do now?
    Uh, I am disinclined to experiment with my iTunes, if you don't mind, so I'm not sure.
    Does the artwork still show up in iTunes because I haven't emptied the trash yet?
    I suspect those files need to be in specific locations in order to be seen.
    Since you downloaded these yourself vs. fetched with iTunes it may be they are embedded in the files and not just present in the artwork folders. I download artwork and then paste it onto my mp3s which means the artwork is actually in the file in addition to whatever file itunes may make based upon the folder. I also notice that if I have a mp3 from the same album but have not embedded artwork in the mp3 it still displays art for that album. I think iTunes is displaying this art using the itc it generated from the album that does have artwork. So it may not matter that you have deleted the itc file if the artwork is embedded in the file or there is another album file with the artwork.
    Is there a way to know where to replace them if I just pulled them out of the trash? That is what I can't figure out based on the names of the files. There doesn't seem to be any corresponding data in the file name as it would relate to the folder that it came from.
    iTunes works in mysterious ways its wonders to perform. I suspect you might be able to replace the files if you were to go into the itunes library files and browse through the entries trying to associate all the code identities from the various listings. Not my idea of fun.

  • SCCM 2012 SP1 - Evil Folders in Reporting Services - What Are They and How to Remove Them

    Hello All,
    There are a lot of sub-folders in the http://CentralSiteSCCM/ReportServer. They are like:
    <dir> Config_Mgr_CEN
    <dir> Config_Mgr_CEN.OLD.0
    <dir> Config_Mgr_CEN.OLD.1
    <dir> Config_Mgr_CEN.OLD.10
    <dir> Config_Mgr_CEN.OLD.100
    <dir> Config_Mgr_CEN.OLD.1000
    Only <dir> Config_Mgr_CEN is properly populated with the correct set of the default folders.
    Would you be so kind to advise on:
    What are they?
    How to remove them?
    What to do in order for them not to appear any more?
