Alias variable cannot  be resolved in the tag file

Hey, somebody with this experience help me, please!
this is part of my tag:
<jsp:directive.tag body-content="empty" import="java.util.*, java.lang.Class, javax.servlet.jsp.PageContext, javax.servlet.jsp.JspContext"/>
<jsp:directive.attribute
name="var"
required="true"
rtexprvalue="false" />
<jsp:directive.variable name-from-attribute="var" alias="local" variable-class="java.util.ArrayList" scope="AT_END"/>
in the jsp:
<tags:mytag var="myTest" />
so the person who used my tag could name var as what he would like in the jsp page. But I always get the error: this script variable cannot be resolved in the jsp page.
e.g.
<%
out.println(myTest.getClass().getName());
%>
compiler always complains the "myTest cannot be resolved".
thanks

Installs fine for me, so I'd guess you got an incomplete or corrupt download. See the Further Information area of Troubleshooting issues with iTunes for Windows updates for direct links and download a fresh copy of the installer.

  • The iPod cannot be synced. The required file not found"

    The iPod cannot be synced. The required file not found" is this something i can fix? i have tried everything.

    Hi,
    here's a work around for the "the required file cannot be found" problem when syncing
    go to your 'iphoto library' in pictures,
    locate your 'originals' folder
    ctrl click it and select 'create alias'
    drag your 'originals alias' folder to your 'pictures' folder.
    go to itunes with your ipod/iphone attached
    click your ipod/iphone
    select the 'photos' tab
    next to 'sync photos from' click the drop down menu
    click 'choose folder'
    find your 'originals alias' folder
    select the photos you want.
    now your ipod/iphone will now sync your photos.
    enjoy

  • When I attempt to sync my nano I get an error message: "The ipod cannot be synced. The required file cannot be found."

    When I attempt to sync my nano I get an error message: "The ipod cannot be synced. The required file cannot be found."

    This is getting frustrating.  Every example of my problem has the same reply:
    Try deleting the iPod Photo Cache folder.  This is normally located in your pictures folder.  Once this is done, try syncing again.

    I have NO photos on my Ipod Nano.  I select "Photos" and the Ipod goes to a blank screen with the msg "No Photos" at the bottom.  There must be some other file missing.  Itunes won't connect to the Ipod, I keep getting the same error over and over.  It would be nice if it told me what file is missing.

  • The iPod "my ipod name" cannot be updated. The required file is in use.

    Installed iTunes 7 on my mac. Everything went fine. Updated my ipod everything went fine. Ever since then I've been getting a dialogue pop up window stating "The iPod "my ipod name" cannot be updated. The required file is in use."
    This pop up happens at completely random intervals, sometimes every minute sometimes every 10 min.
    Its extremely annoying as it bounces the icon in the dock until I give iTunes focus, click ok, and then I can navigate songs etc. I listen to my music thru my iPod while its connected to my computer, so this bug just about has me reverting back to v6.
    I've repaired permissions, and disabled anything I could think of that may be using it, ie synergy etc, with no success.

    I have a 4th Gen 30gb IPOD and updated Itunes 7 sucessfully but could not update/install IPOD 1.2 upgrade.
    Eventually after clicking the message boxes with the above info we seem to be getting, I selected the update button that appears on the front page of ITUNES and it installed/updated. I have been attempting for a couple of days and it just worked!!!!
    After it completed, I received the same dialog box and then disconnected the IPOD from my laptop.
    Seems to be OK now but there is def something going on.
    I thought it may be a shareware issue with mp3's being downloaded into Itunes library form another application.

  • My iPod says "cannot be synced. The required file cannot be found. Always when half way through a sync. It also shows apple logo when I try to access photos and I think the issues are linked. Any ideas?

    My iPod says "cannot be synced. The required file cannot be found" it also defaults to apple logo when I try to access photos. I think the issues are linked. Any ides?

    So you have tried removing/trashing your iPod's photo cache? See here for more information on where to find this file.

  • IPod "cannot be updated.  The current file is in use."....how to fix?!

    I have a MacBook and the iPod Nano that came with it. I also have a 4G(I think) 20GB iPod. I have both configured to my Macbook, using only certain playlists to be updated on each iPod.
    I don't get any problems when I connect the 20GB iPod(w/ the Firewire), but whenever I connect my Nano(w/ the USB, I have to, it doesn't support Firewire), I get a message saying the iPod"cannot be updated. The current file is in use."
    How do I fix this problem? I have my iPod to "Enable disk use", but everything else is OK, and I have separate playlists and designate each iPod to Sync Selected Playlists Only, and have different playlists selected.
    How do I fix this and/or why is this problem happening?
    (and I'm still going to ask any kind souls to check my previous posts and answer my Playlist Question thread, as that is a nagging problem as well)

    I fiddeled around and I am still having this problem. Can someone help me.

  • IPod "cannot be updated. The required file is in use."

    Since updating to iTunes 7 the program keeps saying that "The iPod "iPod name" cannot be updated. The required file is in use." When I click on “OK” it does in fact update. I tried to restore the iPod but couldn’t do it from within iTunes but I could exit iTunes and run the most recent update/restore on it from the desktop.
    Also, I can not eject the Nano from within iTunes “iPod cannot be ejected because it contains files that are in use by another application.” But I can exit iTunes and eject it from the desktop. I don’t have this problem with an older 40 gig iPod.
    I called Apple and they promised to send a work around but it never came.
    Running on a G4 with 10.4.7
    Any suggestions?
    Dual Processor G4 & G5   Mac OS X (10.4.7)   I do have three users using the same iTunes library.

    I just started getting this message today - the only new thing I have done differently since I last synced is to start rating my songs on the iPod.
    Just a hunch but did everyone else start getting this error after their first try at rating songs on the iPod?
    Other than that does anyone know how to report this kind of thing to Apple? as they need to fix it soon.
    The only answer I have seen after 2 hours of searching is to go back to iTunes v6.05 - see Chad Armstrong's tip here: http://discussions.apple.com/thread.jspa?messageID=3116292&#3116292 - but I can't be bothered to go through all that just yet.

  • "ipod cannot be updated becuase the required file is in use"

    I upgraded to itunes 7 this weekend and so did my husband. I am running the latest versions of all mac software with my fifth gen ipod and he is running the same with the ipod mini. We both get teh same error message:
    "ipod cannot be updated becuase the required file is in use"
    I have tried the following with and without guidance from tech support:
    Reboot
    repair permissions
    "restore" on the ipod using itunes 7
    reinstalling itunes 7
    trying to reinstall itunes 6 instead
    removing login in items from automatically starting
    disabling firewall/antivirus
    I stumped tech support yesterday. Anyone else having a similar problem?

    I'm another one who is having this problem. Though it doesnt seem to effect the downloads or the files, it pops up every so often. Cant figure out what file its referring to or what cant be updated. Def has to do with the latest version of iTunes.

  • "iPod cannot be synced. The required file is locked."

    I'm sure there are several threads about this, but none have produced an answer that works for me.
    I have an iPod Touch 1G and iTunes 8.0.1.11, though I don't think that matters. I should probably ask this on a Windows XP website, but I thought maybe I could get some results here.
    Basically my deal is, when I plug in my Touch and let it try to sync (or hit sync manually), I get the error message "The iPod (iPod name) cannot be synced. The required file is locked."
    Ex: http://img410.imageshack.us/img410/8393/20901666.png
    (Also, manually drag-and-drop method of music in the library freezes iTunes.)
    Now, people say to go to your iTunes music folder, usually the one under "My Music", right click and uncheck the "read only" box. I've done that, hit OK, and brought up the Properties again, and it has been re-checked without my doing.
    Could this be iTunes's doing? Or am I doing something wrong? Or should I go ask Windows users?
    Another little bit of info: This only started happening today. I have done nothing different than I have before.

    Alright,
    How did upgrading to the latest version of iTunes go? Did it help any? No, dang! sorry getting ahead of myself I don't even know if it has or not. I have been racking my brain trying to recreate this issue but am having no luck. I did however find a computer running xp sp2 to do some test and such on it.
    Here are some more ideas that my wife and I came up with for you to try,
    1. In iTunes go to (Help)/(Run Diagnostics) in the menu bar (In my opinion you don't need to do the test for (cd/dvd) or (network) but that is up to you. After which I request that you copy and past the report like so:

    Just to see what it comes up with, I don't know if the diag. will fix any issues, since I've never needed to use it but it looks like it will give you a good report of whats going on. Go Apple! *and yes with the report feel free to block out any information you don't want to share.
    2. I was reading around on the internet and I've found that a lot of the times its something simple to fix some of these issues like the one about the time getting messed up when windows xp goes to sleep. So Here is a simple idea to see if it helps.
    Go to (edit)/(preferences) in the menu bar Click on the (Devices) tab and try clicking (Reset Sync History) button. Then try Syncing again. Don't know if it will help but hey worth a shot right?
    3. My wife was looking around on the internet and she found a bunch of info on files that are corrupt not being able to sync, since I don't have a corrupt file and am at a lost in how to make one. I was unable to test this theory.
    However, the information suggested that it may be related to a picture file. so I would look into the (photos) tab in the iPod touch's Summery page and un-check one picture folder at a time and sync to see if it is related to a particular image folder.
    Also beside of the image folder it was noted that some errors are accruing with outlook syncing, so you might also look into the syncing of your contacts and emails in the (info) tab of the iPod Touch's Summery page.
    After those too I would look into music that you have just stared to try and sync and try eliminated one at a time again to see if there is one particular file to be the error.
    *In note of that it is suggested to only do one at a time, since its always best to do a process of elimination.
    4. And last have you tried backing it up in iTunes and then Restoring it. To see if a hard reset like this fixes the issue?
    Here is Apple's knowledge base article on it: http://support.apple.com/kb/HT1414
    *Sorry that its such a long post I just want to save you time waiting for me to get back to you.

  • IPod cannot be synced. The required file cannot be found - Aggghh!!!!

    I have a new iTouch, which is fine, I am just having a very, very bad experience of iTunes., in fact so bad it may go back to apple soon and I shall dust off my old Creative Zen
    The Problem:
    When I try to sync any music, audio book or photos, the message comes up:
    " iPod cannot be synced. The required file cannot be found" and nothing is synced,
    It syncs my contacts and calendar from Office Outlook fine, and the alarm works on the appointments.
    I think I have tried just about everything, I have uninstalled and reinstalled iTunes, done the whole Restore option in ITunes.. run the Diagnostics and all passes fine. I have searched the form and found another answer mentioning security issues, but mine have not changed. It is not the compatibility of photos or DRM with the music, I have tried a single music file (of my own song) and a single compatible photo.
    Googled the darn problem and there seem to be as many differing views on the problem as there are computers out there, from my hard drive being screwed (which it is not) to a registry file missing.. Tried all but…..
    Well if anyone can come up with an answer they can expect a very large thank you!!!
    Any answers?
    Thanks

  • Ipod cannot be synced. The required file cannot be found

    Up until recently, the only thing there was wrong with my Ipod was the occasionally "100% freeze that only could be solved by draining the Ipod from battery", which it did less than three times a month. Then this sunday, when I was going to work (nightshift) I took the bus as usually, and listened to music on my Ipod for about half an hour.
    I hear music and podcasts from my ipod when I work, I connect my ipod to a jackstick and connect it to the radio of the wagon I drive around in. And then it started acting weird. The sound seemed to freeze up, but after 1 min or so, it played a fraction of a second and seemed to freeze up again. So I held down the toggle button and menu button, which did restart it as it should.
    I chose the same podcast and it started playing as if nothing were wrong. But then it did the same thing, and on the display where the name etc. of the item I was playing were supposed to slide from one side of the ipod to the other, was moving a bit and then coming to a complete stop, and then it would move a bit again.
    So I drained it from battery, and recharged it, when I got home from work. When I woke up I tried to play the same podcast, without listening to it, though, it did play, but the timer moved awkwardly, the seconds moved in a funny way.
    Then I tried using the restore function, in Itunes, thinking it would perhaps erase some bad software and installing it all over. But now When I try to synchronize the ipod with my itunes library, it synchronizes a few songs and then the red circle that comes with 'do not disconnect' disappears from the ipod and itunes says "the ipod 'name of ipod' cannot be synced. The required file cannot be found."
    After that the picture with the red circle and the'do not disconnect' freezes up, and the only way to turn it back on is to hold down the menu and toggle buttons, as if trying to get the ipod to go into disk mode. Also, Itunes can't see the ipod anymore.
    I went to the shop yesterday and said there was something wrong with it prior to my restoring it, but the guy in the shop made it sound like it was my fault for pressing the restore button, and that it would most likely start working if the software on it were updated.
    The software on my ipod is up to date, and I've tried removing and reinstalling the newest version og Itunes.
    I'm sorry for the wall of text that just hit you headon, but I hope that telling all the details might shed some light on my problem.
    I hope someone out there can help me, or refer me to another topic with a solution. I just realized how addicted I am to that little piece of hardware.
    Thanks in advance

    UPDATE:
    I've just made an interesting discovery (at least I'd like to think so myself:).
    When I got home from the gym today I plugged my ipod in the computer to recharge the battery (I had without any incidents heard around 60 songs). When Itunes detected my ipod it didn't recognise the library on my ipod and it wanted to restore the ipod and copy it's current library onto the ipod. Fine, I thought since it's completely indifferent. Only Itunes started with error 69 again.
    So I thought, to heck with it.
    I deleted my library 100 %, and I've just finished the hard work of sorting out my new library and my new playlists. I only added music, about 1600 tracks and synced - WITHOUT any errors occuring. I tried then to add the podcasts, of which there are 61 and Itunes was able to sync 55 of these before getting the error 69, the last 5 being podcasts of older date, which it hasn't had any problems with earlier.
    So right now, I'm thinking can the podcasts interfere with me syncing songs? or something far out like that?
    btw. itunes recognises the library on the ipod, so I don't think that's a problem anymore.

    Hi antiklady,
    I see that you may be having an issue with compatibility of iTunes when connecting your iOS device. This sort of issue can arise if you have two versions of iTunes installed on your computer, which I feel may be the case. Here is an article that can tell you how to identify the version of iTunes that you have open:
    iTunes: How to find which version you are using - Apple Support
    http://support.apple.com/en-us/HT201521
    If the version of iTunes that is opened is not the version you are required to use for the iOS device in question, try searching through your computer or applications folder to see if there may be two versions of iTunes installed on your computer. Then, uninstall the version that is incompatible using these steps:
    Remove and reinstall iTunes and related software components for Windows Vista, Windows 7, or Windows 8 - Apple Support

  • Error message: iPod cannot be updated. The required file cannot be found.

    Each time I sync my 5th generation iPod to my laptop and open iTunes, I get the message "iPod cannot be updated. The required file cannot be found." My husband already updated my iPod with the most current Updater (6/28/06). Any thoughts or suggestions?

    After looking further into the archives, I got an answer to my question. There is a file called "iPod Photo Cache", located in the Pictures folder, that should be moved to Trash. Once done, the error message pops up no more!
