Securing Code

Hi, I have a java applet on a webpage, just the class files in a jar file.
How can I stop someone from downloading the class files and turning them into java source files.

I have an ipod touch and I am not able to use any money on my accounts because it is telling me the security code is wrong. Can anyone tell me what I can do?

I am not able to purchase any upgrades on my Ipod, music, movies, videos, or anything because it says my security code is invalid. I am not sure if I am using the wrong numbers or if there is something wrong with my account. I have tried to change my apple Id and my password. Other times I am able to sign on to my Ipod with my user ID and password to do an update and it says there is a billing problem with a previous purchase. then you can tap continue and view further info, and when I do this it takes me to my account settings page with the info that I originally set up my Ipod with. I no longer have that same credit card and would like to remove it from account and update with a new one, but have not been sucessful in doing this by using my Ipod. Can I do this online somewhere? Can anyone help me out?

Try here:

Are you using a credit card?

Security codes
The credit card security code is a unique three or four digit number printed on the front (American Express) or back (Visa/MasterCard) of your card.

HP Officejet 6500, Windows XP and 7, wireless LAN security code is not accepted

The security code of my wireless LAN is not accepted by the HP6500A. According to the diagnostic software of HP a code consisting of more than 50 characters is required (the total number of characters can not be identified because the code isgoing on out of the window). The security code of the route consists of 12 characters. Resetting the printer is not solving the problem.
This problem was identified after rinstalling the software after problems with printing: connection with the printer was identified; message: "busy with printing", but no printing result at all.

Security codes can be in ASCII or HEX. I'm guessing that the diagnostics is reporting HEX and the printer entry is in ASCII.
You can try running the diagnostics SW on the Windows 7 computer. It might return the key in ASCII.
A good option is to get the password from somewhere other than the diagnostics. Maybe you stored it somewhere or wrote it down? Once you get it try to enter from the front panel.
Can I get a little information from you?
What router brand model?
What security mode are you using (WEP, WPA, WPA2)?
Which model of the 6500 do you have (6500 or 6500a)?
Please mark the post that solves your problem as "Accepted Solution"
Sometimes it takes several posts back and forth to get to a solution - please be patient.
I am employed by HP

Is the address on your iTunes account exactly the same (format and spacing etc) as on your credit card bill : http://support.apple.com/kb/TS1646 ? If it is then you could try what it says at the bottom of that page :
If the issue persists, contact your credit card company and verify that they and any company they use to process credit card authorisations have the correct information on file.

This can sometimes happen because there is a missmatch between the billing address entered on your iTunes account and the billing address from your bank records. See http://support.apple.com/kb/TS1646.

Contact the card issuer and find out what the problem is.
Was the card issued in the same countryas the store you're trying to use?

Trying change my credit card info from previously lost credit card but can't since it says I'm accessing from new device and asks for security code for a card i no longer have. What can I do?

I've recently gotten a new laptop and replaced my damaged iphone. Apparently these 2 scenarios qualify as "new devices". This is fine but I also had lost my credit card previously that was connected to my iTunes account, and got a new one with all different numbers. When I try to change my billing information to this new card it won't let me because it says
"Your account has been accessed from a new device, and you must verify your payment information before you can make purchases."
and it asks for the security code of the card I had lost and replaced! I am not able to change my billing info to my new card thus because I can't get past this.
Can anyone please help?

When I tried to log into my itunes account, I was asked to update my credit card information. When I confirmed my credit card info, I got a response about my security code not being accurate -which is not the case-it is 100% accurate. How do I fix?

I keep getting a message about my security code not being accurate. I tried 3 different cards & have the same issue. Is this a systems issue? I need to get my apps installed on my new iPhone 4. I am unable to download without confirming my credit card info- My security codes are 100% accurate.Anyone else having this issue? What is the fix for this?

Ohemod,
There are 120+ countries that have iTunes Stores, but that leaves many that do not. You can consult this document: iTunes Store: Which types of items can I buy in my country?
Opening in a new country requires a tremendous amount of legal, commercial and financial investment, but I am sure Apple would be interested in knowing where there is unmet demand. If you wish to make suggestions to Apple, you can use the iTunes Feedback page.

3 debit cards, updating, and my phone won't let me download apps or music because it says my security code is invalid no matter what I do. Help!!

I don't know wha to do. When I try to get apps (even free) or music on iTunes (even with my gift card), a notice pops up saying there was a problem with a previous billing purchase, then it takes me to my card info and address and no matter what it always tells me my security code is invalid. I've gone through 3 cards (all worked to purchase items from a store or anything) and I've even updated my phone when i was told that I had to do that before I could download anything. I can't figure out what the problem is. PLEASE SOMEONE HELP!!

From iTunes menu Bar, Store > View Account > Edit "Payment Type" under "Apple ID summary"

If it is trying to verify your payment info, I would be willing to guess that it is looking for the security code for your credit card. Did you credit card just get replaced lately or the expiration date change? When is the last time that you updated your payment information in iTunes?

My phone wont let me complete ap updates due to an invalid security code in my billing info which hasnt changed since i got the fone!!! Help

Please someone help me! Im going crazzzzy

You must be using a valid credit (not debit) card.
iTunes Store: My credit card's security code or zip code does not match my bank's records
This is what Apple says in the above: http://support.apple.com/kb/TS1646
In most cases, this issue is caused by a formatting error in the billing address that you have provided. You can correct the issue by verifying that the information you have provided is correct, or by changing the format of your address to match the format that your credit card company has on file.
You can verify and/or modify your billing address by following these instructions:
Open iTunes. If you are signed in to iTunes, skip to step 4.Note: Verify that you are signed in to the correct iTunes account. If you are unsure which account you're signed into, choose Store > Sign Out and proceed to step 2.
Choose Store > Sign In.
Enter your account name and password, then click the Sign In button.
Choose Store > View My Account.
Click the Edit Payment Information button.
In the Payment Method section, choose None.
Click the Done button at the bottom of the page.
Click the Edit Payment Information button again.
Enter your billing address exactly as it appears on your credit card statement.
Select your credit card type in the Payment Method section.
Enter your credit card information, your card's security code, and the expiration date.
Click the Done button at the bottom of the page.
If the issue persists, contact your credit card company and verify that they and any company they use to process credit card authorizations have the correct information on file.
