Need to write object to database but can't find useful examples
Hi,
Within one servlet I need to write an Attributes object to a database to be retrieved sometime later by a second servlet. All the examples of serialization code that I can find are for writing to serial or file streams. What I need is to be able to be able to write the Attributes object to a MySQL database. How do I get it into a form that I can write to the database and how do I once again turn in back into an object? I've not been able to answer those question from the examples I've found so far.
Any help would be greatly appreciated.

There are at least two choices.
1. Serialize to a ByteArrayOutputStream, base-64-encode that data, and save as a string in the database.
2. Serialize directly to a database blob.

I'm trying to share a folder between users on a single mac. I want both users to be able to read and write so the folder stays current on both accounts. I put the folder in "shared," set permissions on folder so other user can read and write, enabled file sharing, but can't find the folder on the second user's account. Any help?
Did you log out of one account and into the other or just used Fast user switching?
Is the permissions set to anyone?
When you move data to teh Shared folder is it copied or just moved?
If copied then it's not a folder both can access, just a way station like a USB thumb drive that things are coped too and off of likely.
You can run this #5 on each user account to reset the user permissions once they are taken back out of the Shared folder

There is nothing that you can do to get rid of the balance on your own. Contact iTunes Store Support and seek their assistance. I believe that they can reset your balance for you.

Stacey FeatherstoneCan you run Firefox long enough to display the Add-ons page? Either:
* Ctrl+Shift+a
* "3-bar" menu button (or Tools menu) > Add-ons
In the left column, click Extensions. Then, if in doubt, disable. (Remove also is available for some extensions, but not the ones that Firefox found in a registry scan or shared folder elsewhere on your system.)
Often a link will appear above at least one disabled extension to restart Firefox. You can complete your work on the tab and click one of the links as the last step.
Any improvement?
If you cannot access the Add-ons page, try starting Firefox in Safe Mode, since that deactivates extensions and hopefully will stop that message from coming up long enough to get to the Add-ons page.
''If Firefox is not running:'' Hold down the Shift key when starting Firefox.
''If Firefox is running:'' You can restart Firefox in Safe Mode using either:
* "3-bar" menu button > "?" button > Restart with Add-ons Disabled
* Help menu > Restart with Add-ons Disabled
A small dialog should appear. Click "Start in Safe Mode" (''not'' Reset).

How do you change apple id for icloud if phone is already set up. Need to give each phone in my account their own apple id for icloud so that we dont receive each others messages but can still all use same id for purchases.
Settings-icloud-scroll to the bottom, select delete, if you want to keep the content select keep, otherwise it'll remove it. Then once it is done add the account information for the account you want on that phone. Your apple ID in settings-store will remain the same and each device can still purchase/use content from that account.

I need to reset my security questions, but can I message support by text and not call or if you can tell me how to reset my questions here that will be great and I don't have a rescue email.
If you've forgotten the answers, you can't do that yourself. Click here, tell the iTunes Store staff that you can't call, and see what they say.

i need to add a new computer and take off a old one but can't find the site or place to turn it off i can only have two computers but i got three please help let me know where to go to shut one off to put the new one on?
Hello,
the way is written there Activation & deactivation help >>> (see there only to understand the procedure) Common activation problems >>> "Activation limit reached for [product]. This serial number has already been activated on 2 computers." "Maximum activations exceeded."
>>> How to deactivate or sign out >>> A single license for Adobe software lets you install the applications on two computers—for example, at home and at the office. However, you can use the software on only one computer at any given time.
If you want to install the software on a third computer, deactivate the software on the computer on which you will no longer use the software. Then, activate the software on the new computer.

I need to download ferefox 9.0 but I cannot find it anywhere. Who can help me with this?
Please note that running out of date versions of Firefox is not recommended, as you will open yourself up to known security issues, alongside bugs and other issues. Is there a specific problem you are having with Firefox that I can help you with?
You can download Firefox 9 at [http://ftp://ftp.mozilla.org/pub/firefox/releases/9.0.1/win32/en-US/ ftp://ftp.mozilla.org/pub/firefox/releases/9.0.1/win32/en-US/] -

New computer, new itunes, but can't find the link to authorize the new computer. What?
You should have a series or drop-down menus at the top of your Mac's screen, one of which should be 'Store' :
Do they not show ? If not, then have you got iTunes in full-screen mode - if you have the control-command-F should toggle between full screen and normal.
