You can use Assistive Touch:
http://support.apple.com/kb/HT5587
Once Assistive Touch is turned on:
Tap the dark circle to open the Assistive Touch menu, then tap "Device" and tap and hold the Lock Screen icon. This will bring up the iPhone's Power-Off slider. -

C:\JSDK2.0\servlet.jar
and the path as
%SystemRoot%\system32;%SystemRoot%;
%SystemRoot%\System32\Wbem;
C:\jdk1.3.1_02\bin;%CLASSPATH%;
C:\JSDK2.0\bin;%PATH%
but still doesn't work. and i have also installed apache jserv. however i am able to view the servlet file,"IsItWorking" in the browser. but when i place my servlets into the same file, it doesn't work.

thanks!The only other possibility would be for it to print "Error!", and that would only happen if the parsing threw an exception. Since you do not see that, it means that the parse was successful. Why is this a problem?

Please can someone tell me why I cannot reinstall my upgrade from lightroom 4 (lightroom 3 installed off disc with serial no) my hard drive crashed, and I am trying to get lightroom 3; 4 and 5 back on so that I can link my catalogues and continue work. I cannot install lightroom 5 until the upgrades from 4 are on the pc, (lightroom 3 installed off disc but 4 is a copy of the upgrade download I got when I bought it) These serial no's are legit and are registered under my account with adobe, but it still gives me the Big Red Cross when I put my serial no in! Please can someone help. I am at a loss. Thx Heidi

You don't need to have Lightroom 3 and 4 installed on your computer to install Lightroom 5. Just install Lightroom 5 and input your serial number for 3 in the previous version box and your serial number for 5 in the upgrade box. -
a pop up says "it cannot be open b/c it's not supported on this architecture." Why? It worked fine until now.
What can I do so that I can open iphoto. I have so many photos in the application.To re-install iPhoto
1. Put the iPhoto.app in the trash (Drag it from your Applications Folder to the trash)
2a: On 10.5: Go to HD/Library/Receipts and remove any pkg file there with iPhoto in the name.
2b: On 10.6: Those receipts may be found as follows: In the Finder use the Go menu and select Go To Folder. In the resulting window type
/var/db/receipts/
2c: on 10.7 they're at
/private/var/db/receipts
A Finder Window will open at that location and you can remove the iPhoto pkg files.
3. Re-install.
If you purchased an iLife Disk, then iPhoto is on it.
If iPhoto was installed on your Mac when you go it then it’s on the System Restore disks that came with your Mac. Insert the first one and opt to ‘Install Bundled Applications Only.
If you purchased it on the App Store or have a Recent Mac you can find it in your Purchases List. -

why I cannot update my ipad from 5.1.1 to latest versions? Some of the apps wouldn't work on the 5.1.1 . To buy a new ipad,would be a rip off. What is the solution?
The original iPad does not have the memory and processing power to run more recent version of the iOS. 5.1.1 is the latest it can run.

Can someone tell me why Apple cannot produce a Scabble game that works on Mountain Lion. So frustrated that this is not happening with all the technology available.
The only companies that can make a Scrabble game are the companies that own the rights to the game; Hasbro owns the rights in the US & Canada, Mattel owns the rights outside of the US & Canada.
You need to be speaking to those two companies. -
my iPhoto will not work with Yosemite, and it says that it was purchased under a different account, but that's not the case. Any ideas why I cannot update iPhoto?
How did you buy iPhoto? Did it come preinstalled on your computer with Lion or later, or did it come with Snowleopard on system installer disks?
Which version of iPhoto?
If you have a version of iPhoto '11 and it is showing on the Purchased tab of the App Store, with your Apple ID, then delete iPhoto from the Applications folder (don't empty the Trash) and download iPhoto again from the Purchased tab.
If that does not work, contact The App Store Support from the Quick Links on the AppStore main page.
Only apple Support can fix problems with apple ID. -
i am trying to connect to my friend's wifi, i have a very strong signal indicated on my ipad, but cannot connect to the internet. Yesterday i connected without any problem, can anybody tell me why i cannot connect today?
Some things to try first:
1. Turn Off your iPad. Then turn Off (disconnect power cord for 30 seconds or longer) the wireless router & then back On. Now boot your iPad. Hopefully it will see the WiFi.
2. Go to Settings>Wi-Fi and turn Off. Then while at Settings>Wi-Fi, turn back On and chose a Network.
3. Change the channel on your wireless router (Auto or Channel 6 is best). Instructions at http://macintoshhowto.com/advanced/how-to-get-a-good-range-on-your-wireless-netw ork.html
4. Go into your router security settings and change from WEP to WPA with AES.
5. Renew IP Address: (especially if you are droping internet connection)
• Launch Settings app
• Tap on Wi-Fi
• Tap on the blue arrow of the Wi-Fi network that you connect to from the list
• In the window that opens, tap on the Renew Lease button

You don't download anything at all. The feature is built into the iPhone 4 already. Your carrier has to support the feature and there might be an extra charge to use it.
