Problem with Servlet that generates HTML

Hello,
I have a servlet that connects to a database to get some information which it displays in a HTML file generated by the same servlet.
For each line that I want to display from the Database I create the following in my servlet:
<input type="hidden" value="Ajax-Chelsea" name="bet_1_choice"/>
However, when I test it in Tomcat it doesn't work, and I realised in Firefox that it gets the above line as follows with the bold part added:
<input type="hidden" )="" value="Ajax-Chelsea" name="bet_1_choice"/>
I also use a javascript to add the DB information in another area of the HTML page, another table, but I don't know if this is relevant.
I don't understand what is wrong. Can someone help me please?

Thanks for your responses.
Actually the problem was my javascript. Now it is sorted out.

I'm having problems with iTunes that keeps changing the genre of music that I have already changed

I'm a Dj and I make extensive use of inteligent playlists mostly defined by genre and classification.
I currently have about 70 different playlists, and almost everyone are very important, because I know what music to play, but in some cases I don't remember the name. So it's very usefull for me to know where I can find it according to the genre that I defined.
BUT!! WHAT HAPPENS IS THAT iTunes keeps changing the genre of some music to the previous that is available on the itunes store (that I don't use because is too vague)
Do you know what might be happening?

Hello Torre,
DAQmx is in fact more efficient than Traditional DAQ, so this behavior you describe shouldn't be the rule. I haven't been able to debug/check thoroughly your code, so here's what I suggest:
a) Try the W2000 option to give more time to background processes (see this link).
http://zone.ni.com/devzone/conceptd.nsf/webmain/28A6979ECA9A0CAF862569050053D92D?opendocument
b) Try with the LabVIEW supplied DAQ examples which do a similar task and test/compare their performance
c) Check with the LabVIEW tools where the time is spent (Profile VIs tool)
Hope this will help !

You need to tell us A) what app did you create those files with? and B) what format are they in (.doc, .txt, etc)?
It may be possible to just transfer the files and your font to another machine without conversion depending on how they were made.
Where did you get the BengaliCS font?

Having problems with key chain password

I just got my mac book yesterday, and I'm having problems with my keychain password.
My keychain password is not the same as my login password, it won't accept it, so i think i made a typing error.
Each time i go on to safari, it asks for the password, which i don't have. i've tried the key chain first aid, and that still doesn't work. I've also tried keychain access, and that also doesn't work as it asks for the password first!
Is there a way that i can reset it?

There are user passwords and Administrator passwords. The only way to check your keychain password is to be the administrator. In an effort to secure my MacBook, I have an administrator account that I don't use at all and I have a user account that is all I use. It is a great way to protect your MacBook info from others.
As to your question, passwords are case sensitive. You can try to change the password by inserting the CD's that came with your MacBook and reset the password. Seeing that you just got it yesterday, you probably don't have much personal information on it yet, you could use disk utility from the CD and reinstall the Operating System.
Good Luck.

I'm having problems with excessive email usage on my iphone 4/ios 7. Just noticed that (settings/usage) it was using 900 mb. I deleted all my mail, deleted the mail account, and it still says it's using 661 mb. My ipad uses a fraction of that.

I'm having problems with excessive email usage on my iphone 4/ios 7. Just noticed that it (settings/usage) was using 900+ mb. I deleted all my mail, deleted the mail account, turned the phone off and back on, downloaded any remaining mail on the server to Outlook on my computer, and it still says it's using 661 mb. My ipad uses a fraction of that.
Background: I recently (December) bought an ipad and set up icloud for contacts and calendar, but NOT mail. My email provider is Verizon. I use computer, iphone, and ipad to check my email; eventually I download it from the server using Outlook on the computer and then delete any remaining emails from the phone and ipad. I can't find info on this problem anywhere.

Howdy there COUGAR444,
It sounds like your iPad all of a sudden seems to be restarting out of no where. If you haven't called AppleCare yet, I would start with quitting either the app that seems to be causing the issue, or all the apps if a single doesn't seem to be the culprit.
iOS: Force an app to close
Double-click the Home button.
Swipe left or right until you have located the app you wish to close.
Swipe the app up to close it.
When you have done that restart the device and test the issue again:
iOS: Turning off and on (restarting) and resetting
If the issue persists, backup your device to iTunes, then restore it as new and verify that it works.
How to erase your iOS device and then set it up as a new device or restore it from backups
If it does, then restore your backup to either verify it still works and the software just needed reinstalled, or isolate the issue to the backup file itself.
Thank you for using Apple Support Communities.

Sterling

" When I did this, my library showed all the music I have "purchased" from itunes but did not have the music that I downloaded a long time ago through itunes from my old CDs."
Correct.
" How can I get that music to show up in my library now on my new computer? "
Copy it from your old computer or your backup copy of your old computer.
The sync is one way - computer to ipod.

Hi, I have an Iphone 3g that is "Not" jailbroken, nor do I want it to be jailbroken. However, I had been having problems with it shuting down and not starting again. So, I tried to update and restore only to get an "error" 1015.
It is now stuck on "connect to itunes"
Any help would be great as this is a factory unlocked phone

Apple in no way blocks devices.
Carriers can blacklist devices from their network. If that is what has occurred, only the carrier can remove the blacklist. This should have nothing to do with your ability to activate the device and use it as an iPod.

It is locked to your sisters carrier.
She would have to ask her carrier if they unlock iPhones and if she qualifies for this service.
