Back Issue again
Hi.
I have the following problem:
My application has some JSP pages , each such JSP page genereates HTML,
In one of these pages there is table with rows and rows may be deleted or added by pressing on button.
Delete and Add I'm performing via DOM. And this works well. But when I go to next page and return by "Back" button all changes( deleted rows and added rows ) are disappeared....
I tried to use in :
response.setHeader("Cache-Control","no-cache");
response.setHeader("Pragma","no-cache");
response.setDateHeader ("Expires", 0);
But that didn't help.
How JSP page may be loaded again by pressing on "Back" button? Or how I can resolve this problem in another way?
Thank you.
Yes he posted the question yesterday. Yes you answered it yesterday. But I think the problem is one of the browser caching the page, rather than him trying to do something he can't. I am of course assuming some intelligence behind the post, which might be a little much given this forum, and the fact that he reposted it only today ... but innocent until proven guilty :-)
I am assuming that after all the DOM manipulations of adding rows/columns etc you push a save button, which saves the changes, and takes you to a new page.
However pressing the back button takes you back to the browsers cached version of the page without the changes. ie the browser caches the page despite putting in all those headers to stop it doing so.
So here is a possible solution from http://support.microsoft.com/default.aspx?scid=kb;EN-US;222064
Put <HEAD><META HTTP-EQUIV="PRAGMA" CONTENT="NO-CACHE"></HEAD>
at the BOTTOM of your HTML page, and see if that might stop it being cached
Good luck,

HT4623 iPad air won't automatically connect to wi fi unless I turn off and back on again??
My iPad air will not automatically connect to wi fi unless I turn off and then back on again, any suggestions as to why?
Hello Juanita289
Check out the article below to troubleshoot issues with connecting to WI-Fi. You may want to reset the Network Settings by going to Settings > General > Reset > Reset Network Settings. It will not delete remove any personal data besides and known Wi-Fi networks that you have joined in the past.

My mail will not delete. When I move it to trash and then delete it, within a few minutes it has all bounced back in again. Checked my preference settings and all seems to be in order. Any ideas how to resolve this frustrating problem?
That sounds like a compatibility issue with an add-on that you have installed, as reported by a number of users in both Firefox 22 and Firefox 23 over the last couple of months. If you would provide a listing of your installed extensions ''(as you were prompted to do when creating this thread)'' maybe one of us can advise you which extension is the mot likely culprit. You will need to re-install Firefox 23 to do further diagnostic testing.
As far as the compatibility of Firefox 23 and Win XP SP3, Mozilla has verified they are compatible and not one user ''(including me on two separate PC's)'' has reported a problem with compatibility. -
my imac G5 turns off on mi and dont want to turn back on at all but nex day tuns on normaly then tuns back off again
It could be several possible issues.
1) Your G5 iMac could be overheating. Depending on which model, you might be able to open the back by yourself (not on an iSight model), and using a can of compressed air, youcould blow the dust out of it.
2) The power supply could be going bad.
3) The hard drive could be going bad.
There could be several others.
If you have the original, came with the iMac when purchased new Install Disks, you can try running the Apple Hardware Test to see if it can determine any hardware issues. It can't always find the problem.
Good luck. -
AOL iTunes Login Issue AGAIN?!
As with many other people, I have experienced a problem over the years (since 2006ish) where iTunes won't recognize my AOL login information -- and yes, my screen name and password are both absolutely correct. I can even log in to AOL directly to get my e-mail and use AOL IM. When I punch in my AOL login info, iTunes keeps insisting that my AOL password is incorrect and advises in the error prompt to call AOL at some 800-number to change my password. I wish that this problem were fixable by changing one's password and/or calling AOL -- many of us have tried in the past, and it's a futile attempt.
Over the years, it has been established that it's definitely an issue from Apple's end, not AOL's.
As of last night, I'm having this same problem again. In the past two days, the problem seems to happen sporadically -- sometimes I can login briefly, but I can't login most of the time. This afternoon, I checked the forums to see if anyone else was experiencing this issue again, but I didn't see any recent complaints. However, I did look back in the forums at posts from previous years, and I've tried many of the old fixes that previously solved my issue -- making sure my iTunes is updated, trying to completely sign out, shutting down my computer, etc. I recall some kind of solution that involved updating one's credit card info of sorts -- but I couldn't find the precise instructions for that in the forums (if anyone has this info, please post below so I can try it). I'm really, REALLY frustrated to see this issue occurring again with iTunes, and I can't fathom why on earth logging into iTunes through my AOL account continues to be an issue after so many years.
Is anyone else having this problem right now (or recently)? If so, any ideas for a fix this time around? I have not e-mailed Apple yet, but I'm hoping maybe someone else here has done so already since it often takes a very long time to hear back from them. If you have heard from Apple, what have they advised?
Also, if you could post a direct Apple e-mail address for me to "complain" to and get tech help for this sort of issue, that would be really helpful since I could not find it.
I use iTunes for both work and play, and I really have things that I need to access and/or download. Sigh, not fair to paying customers to have this problem happen so many times over the years. There should be a compensation clause in the TOS that makes Apple give something like $50 or more (either cash/credit, fee based upon amount of pain/suffering, missed work deadlines, missing relaxation time, etc.) for each day one's account is not working due to issues caused by Apple -- I can dream, can't I, lol?!?!
Let's hope this issue resolves itself ASAP!! Thanks to all who post/reply below in advance -- I really appreciate your help/comments!
Marsha
P.S. If need be, I would be happy to attach my iTunes screenshots that show the problem . . . but anyone who has used AOL to sign into iTunes will likely know exactly what I'm talking about without seeing screenshots!I'm sorry to hear you're having the same problem, Dolphin -- but at least I'm not crazy!
The last few times this happened from 2006-2010, there were dozens of posts here in the forums with other AOL users trying to help each other come to a solution -- and unfortunately, there was never one solid fix. Since nobody posted with complaints about this problem recently, I went digging through the old suggested fixes (some of which cleared up the issue in the past), but they have not worked. I thought maybe the problem may be with my iTunes on my laptop, so today I tried to login using my iPad and iPhone . . . same issue. It's definitely my iTunes account. I can still get into my AOL e-mail account without a problem. I'm SO frustrated.
I'm not sure what purpose you use iTunes for, but you're amazing if you're able to patiently wait for the problem to resolve itself -- apparently I'm not as patient as I thought, lol!!! To name a few examples, I use iTunes various services (including podcasts, apps, iTunes U, music, TV documentaries, etc.) for personal recreation, professional development, and for medical information, etc. If it were just for myself, I'd try to wait a bit longer . . . but when it's for professional endeavors, waiting isn't a feasible option!
Dolphin, if you happen to find a resolution, please post here again -- I'd really appreciate it! Do you happen to have a direct e-mail address to get technical support from Apple for this type of problem? I was looking on their support website, but I could not find an e-mail address other than one for questions about purchases. They rarely look at this community support website, so it's unlikely that they'll see this thread I made. However, if I can get an e-mail address, then I'd be able to send them the link to this thread I created that describes the issue. If you e-mail Apple, you can also send them the link to this page if it will be helpful to you since I described the nature of the problem.
Thanks SO much for posting!

Apple,
What really upsets me the most, aside from not being able to get work done as I described above, is all of the deals and promotions I have missed out on (and will still miss until this problem gets resolved) in the time I haven't been able to use iTunes. Not to sound like a sob story, but I think Apple needs to understand how their repeated technical issues with this AOL login thing happening so many times since 2006 impacts people's lives. I have a permanent disability and medical issues from an accident I had back in 2003. I have no income (I got hand-me-down iDevices from great friends when they upgraded), and I can't easily get out of my home to have a good time -- so I truly rely on finding freebies and deals on iTunes to sustain my recreational fun (I even use some apps as part of my physical/cognitive therapy regimen!), and I'm very thankful when Apple and others make special offers so I can have my fun! I missed out on getting a whole bunch of apps I wanted while they were free -- there was, perhaps, $30-$35 worth of apps that I could have had through FreeAppADay.com, free promotions from individual developers, and through other free app promoters like OpenFeint, etc. Plus, I also missed other free promotions for songs, music videos, TV shows, etc. that Apple, musicians, music festivals (ie: Lollapalooza, etc.), and companies offer by giving redemption codes and/or can be downloaded without a code (if featured by Apple directly) -- I also estimate maybe $40 bucks worth of stuff I missed out on because the offers have already expired. So I've already lost out on roughly $75 worth of stuff, plus more for every other deal I'll miss until Apple can fix this problem. I never ask for anything, but it would be a really nice gesture and appropriate if Apple gave me a gift card to cover the cost of the $75 I've missed (plus a bit more $ for each additional day until they resolve my issue) . . . but alas, I'm dreaming cause I doubt they could do this in reality.
So please, Apple, come to my rescue! I need to access my downloaded stuff on my laptop, and I need to download a heap of media from iTunes on a daily basis for my volunteer work, personal education, for fun, for my medical condition -- and SO much more! I do make purchases on iTunes and from the Apple Store when I get money gifts from friends for birthdays and such, so I am a paying customer like any other person. Please Apple, help me . . . and anyone else with this problem. Find a fix ASAP . . . but please work on a permanent solution so this problem never happens to anyone else using an AOL login. It's aggravating, inconvenient, and you'll lose customers this way. I love iTunes and my iDevices, and I want to be able to use and enjoy them.
I'm sorry if I'm ranting a bit, but I'm upset/frustrated and want you to understand how this can affect me and others experiencing this problem.
Please contact me at my AOL e-mail address if I can give you any information that will help you help me, and thanks for your help in this matter!

My Imac will suddenly turn off without warning and then take several hours before it will switch back on again. Can anyone advise?
I like that third tag...
There's really no telling what the problem might be - you may want to try running the Apple Hardware Test (if you can) to see if you've a hardware issue. If you can't even get to the AHT, you've no option but to take the machine into your local Apple Store or an AASP and have them run diagnostics on the machine.
Sorry,

I have had a reinstall nightmare getting my loops back they are in the apple library, I can access them through the media browser but I only have a few available through the loop browser, how do I get them all back there again? please help
"Where do I find my hundreds of dollars of downloads I have done since 2005?"
They will only be where you put them If you are doing the very basics, then they will be on your computer and they will be in your backup copy of your computer.
The itunes store is not global at all, never has been. You cannot redownload your content from another country. You can only use the countrys itunes store for the country that you are physically located. -

I have had a problem with my iphone 4s for some time now but I have just been so busy to try and fix it. When I try to disable cellular data in the settings for my apps it will toggle fine, but once I exit and go back in to the cellular settings its back on again all by itself. However, even though it says the data is on, I can’t use the data when I don’t have wifi. I tried restoring my phone a few times and the last time I did that, it wouldn’t turn my service on so I had to talk with a Verizon agent for a long time trying to fix it and finally they simply sent me another phone. I thought hey new phone, this part will be fixed. However, I got my service to work but it’s still the same problem with the cellular data. I have just left it alone and not worried about it, but it’s still not fixed and thought I could ask on here if anyone had any ideas. It has something to do with the apps actually installed on the iphone. Apps like the mail, safari, settings, itunes apps, etc. All my other apps turn on and off just fine. Does anyone have any ideas?
Read the User's Guide... it covers how to backup and sync the device as designed.

Hi
I have recently bought a white iPhone 4S on Tuesday, and it has been repeatedly loosing all connection and just suddenly switching off.
When this happens I am unable to turn the phone back on again without a power source plugged into it. When I try to remove the phone from the power source it goes completely dead again.
However, the most recent time this has happened (today), as soon as I returned home the phone had no problem starting up as normal when I pressed the power button.
The signal was working fine even though it says 'searching' in the left hand top corner of the screen. I am wondering if my WIFI at home is influencing the phone to work inside the household?
This is a problem that needs to be sorted out ASAP because the phone is not working the majority of the time when I need it to.
Please if you have any suggestions or know the cause of this problem inform me straight away.
Would be much appreciated.
Thank you.Try connecting it to your iTunes library in Recovery Mode and restoring it. See this article for help on getting your iPod into Recovery Mode.

i have an iPad 2 and the volume icon is in the middle of my screen and when i try to turn the volume down it just goes back up again and it makes it impossible for me to play games or do anything
Have you tried giving it a reset? Hold down the sleep and home keys for about 20 seconds. When you see the silver apple let go and let it reboot and see if htat helps.

Some albums I put on my Mac to later sync with a Touch appears as seperate tracks and not a single album. How do I get them back together again other than a playlist. I do not want the tracks showing up as albums on the Touch?
Are your tracks pat of a collection? Different artists, but still one album? Then mark them a s acollection or set the album artist. See this guide on how to group separate tracks into albums:

I have a Seagate Freeagent 1TB external drive that ejects it's self in the middle of the time machine backup, then disappears and can't be found unless I turn it off and back on again. Any ideas?
Hmmm.. sorry to jump in but...
I Wish I had seen this before I got mine.
Mine has been doing this auto eject stuff too.
I think I just plugged it in and TM let me select it but is it possible
I should have reformatted it with DU first, like with all the WD drive problems ?
Is it too late for that ?
Or just try to return it or get rid of it ?
TIA -
When using Time Machine, if I delete items from my computer, will they still be backed up to access later on my external hard drive?
In other words, when time machine backs up again, will it delete the files from the back up that I have deleted from my computer?No, I do not believe so. Time Machine would keep all those now-deleted files in previous backups, and as time goes by those backups might be deleted if you needed room, but it would still keep one backup from each day in last month, as well as one from each week forever, as long as you don't start running out of room, then just the oldest would be deleted to make room if needed.
I use a backup drive about double the size of my drive to be backed up, so I would guess it will never get to the point where deleted files being replaced by new ones being backed fill up that drive to the point where backups actually have to get deleted.
