Path is correct, still won't work

Sup, total noob here.
I'm doing the Hello World tutorial, and I compiled it successfully (path worked, all i had to do was type "javac HelloWorldApp.java") and then I tried to run it with "java HelloWorldApp"
Now I get the Exception in thread "main" [etc] error, and the tutorial says that means i need to change the path. Problem is, I've gone to control panel> system several times, and verified that the folder the path leads to contains both "java" and "javac", so I have no clue what is going on. Also, the problem is not that I need to exit the command prompt and start it up, nor is it that I didn't click ok when changing the path.

Paste in the exact command you entered and the exact error message.
This is NOT a path issue. Path is fine. It's finding java.exe. If it weren't, you'd get
'java' is not recognized as an internal or external command,
operable program or batch file. if you're on widows, or something like command not foundon unix.
It sounds like a classpath error (which is completely different from path).

java -cp .;<any other directories or jars> YourClassNameYou get a NoClassDefFoundError message because the JVM (Java Virtual Machine) can't find your class. The way to remedy this is to ensure that your class is included in the classpath. The example assumes that you are in the same directory as the class you're trying to run.
javac -classpath .;<any additional jar files or directories> YourClassName.javaYou get a "cannot resolve symbol" message because the compiler can't find your class. The way to remedy this is to ensure that your class is included in the classpath. The example assumes that you are in the same directory as the class you're trying to run.

Ipad safari autofill still won't work :[

Hi,
Just bought me a new iPad 32gig refurbished model and am having problems with safari.it's supposed to save all my passwords on websites so I don't need to type them ever time but it just won't work.
The autofill box is on and and have even reset the iPad a few times & cleared the cache but still won't work.looking at the web it looks as if it's a bug so is there any fix yet ?...
King regards
Paul

You didn't enter the command correctly, but that doesn't matter, because it's obvious that you do have misconfigured permissions.
The procedure below will reset the permissions of a home folder in OS X 10.7.4 or later. If you're running an earlier version of 10.7, update to the latest version first. This procedure should not be used in OS X versions older than 10.7.4.
Back up all data before you begin.
Step 1
Click the Finder icon in the Dock. A Finder window will open.
Step 2
Press the following key combinations, in the order given:
Command-3
Shift-command-H
Command-I (The letter "I" as in "Info.")
The Info window of your home folder will open.
Step 3
Click the lock icon in the lower right corner and authenticate with the name and login password of an administrator on the system. If you have only one user account, you are the administrator.
Step 4
In the Sharing & Permissions section of the window, verify that you have "Read & Write" privileges. If not, use the "+" and "-" buttons in the lower left corner to make the necessary changes.
Step 5
By default, the groups "staff" and "everyone" have "Read Only" privileges. With those settings, the files at the top level of your home folder will be readable by other local users. You can change the privileges to "No Access" if you wish, but then your Public and Drop Box folders will be inaccessible to others. Most likely, you don't need to change these settings.
Step 6
If there are entries in the Sharing & Permissions list for users or groups other than "me," "staff," and "everyone," delete them.
Step 7
Click the gear icon at the bottom of the Info window and select Apply to enclosed items... from the drop-down menu. Confirm. The operation may take several minutes to complete. When it does, close the Info window.

Connect your phone to a computer and restore your software using iTunes.

Try:
- Reset the iOS device. Nothing will be lost
Reset iOS device: Hold down the On/Off button and the Home button at the same time for at
least ten seconds, until the Apple logo appears.
- sign out and the sign back into Game Center
- Reset all settings
Go to Settings > General > Reset and tap Reset All Settings.
All your preferences and settings are reset. Information (such as contacts and calendars) and media (such as songs and videos) aren’t affected.
- Restore from backup. See:

So, I have created my home sharing from my base computer to my laptop. On my lap top I see the tab for home sharing but it will not let me connect to my computer to share my music over. I have done everything iTunes has told me to but it still won't work.

I got some more info that may help.
I put a cd on my laptop, and was able to share it to my computer... So the problem is only from my computer to my laptop. I tried the firewall thing and it did not help. I read the rest of the trouble shooting page, and nothing else applies. iTunes is an execption and already was. I can not think of anything else being my problem. Do you think I should re-install iTunes or would that be a waste of time? At this point I am about to just call Apple for some help because I am getting to stressed over this.
Thanks

Let's try a standalone Apple Application Support install. It still might not install, but fingers crossed any error messages will give us a better idea of the underlying cause of the issue.
Download and save a copy of the iTunesSetup.exe (or iTunes64setup.exe) installer file to your hard drive:
http://www.apple.com/itunes/download/
Download and install the free trial version of WinRAR:
http://www.rarlab.com/
Right-click the iTunesSetup.exe (or iTunes64Setup.exe), and select "Extract to iTunesSetup" (or "Extract to iTunes64Setup"). WinRAR will expand the contents of the file into a folder called "iTunesSetup" (or "iTunes64Setup").
Go into the folder and doubleclick the AppleApplicationSupport.msi to do a standalone AAS install.
Does it install properly for you? If so, does iTunes launch properly now?
If instead you get an error message during the install, let us know what it says. (Precise text, please.)

Try:
- iOS: Not responding or does not turn on
- Also try DFU mode after try recovery mode
How to put iPod touch / iPhone into DFU mode « Karthik's scribblings
- If not successful and you can't fully turn the iOS device fully off, let the battery fully drain. After charging for an least an hour try the above again.
- Try on another computer
- If still not successful that usually indicates a hardware problem and an appointment at the Genius Bar of an Apple store is in order.

Okay so my IPod touch 4 won't play music through any headphone I put into the port. I've tried it with 4-5 different headphones but it still won't work. How can I fix this?

Okay so my IPod touch 4 won't play music through any headphone I put into the port. I've tried it with 4-5 different headphones but it still won't work. How can I fix this? This isn't the first time something like this has happened but it has never stayed this way for such a long time. If I have to send it in for repairs I will but I'm not sure if its under warranty

To check for warranty coverage:

- Try cleaning out/blowing out the headphone jack. Try inserting/removing the plug a dozen times or so. There is a little switch in the headphone jack that disconnects the speaker when the headphone jack is inserted.
Try the following to rule out a software problem
- Reset the iOS device. Nothing will be lost
Reset iPod touch: Hold down the On/Off button and the Home button at the same time for at
least ten seconds, until the Apple logo appears.
- Reset all settings
Go to Settings > General > Reset and tap Reset All Settings.
All your preferences and settings are reset. Information (such as contacts and calendars) and media (such as songs and videos) aren’t affected.
- Restore from backup
- Restore to factory settings/new iOS device.
- Make an appointment at the Genius Bar of an Apple store. Seems you have a bad headphone jack.

What still won't work? You have the photos in a folder on the Desktop, right? So what happens when you drag that folder onto the thumbdrive? Many such drives have a slider lock switch. Make sure it's not in the locked position.
Otherwise give us more detailed info on your setup and issue.

I'm having all kinds of problems since loading Lion and I really wish I hadn't bought it yet. Even after the software update today, 1. my modem still won't work, 2. Photoshop Elements produces muddy photo prints, etc. Anybody at Apple listening?

10.7 was horrible unstable so I waited until 10.7.1 and tried it again. Well I have to say that it is still a defective OS. I am reverting to Snow as we speak from my carbon clone copy.. This is really the worst OSX I have ever used. It gives me random Kernel panics for no reasons, unstable airport and hundreds of small issues that are just not necessary. For instance I can't use QuickTime in Lion to trim a videoclip ( the UI goes mad and the trimslider becomes inoperable and hangs the Player window ) while in Snow it is no problem. Itunes gives me crackling sound when the equalizer is turned on, Graphical glitches in Photoshop, games crashing, Preview.app not working with some pdfs, so I need Adobes reader which I never used before.. It is definately not ripe for mass usage. Might 10.7.2 or 10.7.3 fix it, but not yet.
* and just for the records : the hardware is absoltely ok. Because in Snow it works as it should. ( So many Lion fanbois are talking : "your Ram is defect", defintely NOT. - Lion is defect! ).
Shame on you Apple.
