Under this condition, can I use JNI?

Hi everyone,
I am planning to use JNI for a project, but I only have several DLLs (no source code for them, but only have header file for these DLLs). Can I use JNI to invoke methods in these DLLs directly? Examples in internet are making me believe that I have to use javah to create a header first, and compile this header with C/C++ source code into new DLLs, and then my methods in Java can use methods in DLLs. Am I right?

O, getting understand that I have to write a C/C++ wrapper to make it work. Is there any one who has a small sample to show me how to write a C++ wrapper? Thanks a lot!

Can I use JNI in my xlet?

Can I use JNI in my xlet? Is there any security issues?

The JavaTV specification doesn't prevent you using JNI, but the MHP and OCAP specifications do.
Apart from the security risks (code running outside the Java sandbox and potentially subverting all of the MHP/OCAP security and resource management), the problem is that there are so many different hardware and software platforms. You need to compile the native code for a particular STB, and you simply have no idea which platforms will be deployed. This makes JNI impractical except on very tightly controlled networks.

My itunes comes up with this when i try to download purchased songs: this devise is already associated with an apple id. this devise can be used with another apple id in 82 days. i need help to see if i can fix this problem please.

i have an iphone 4s i signed out of my itunes on the devise and my friend signed herself into ituned but i signed her out an myself back in but my purchased songs and tones cannot download. it gives me a message of:this device is already associated with an apple id. this device can be used with another apple id in 82 days! is there anyway for me to fix this or override something. im freaking out!!

Sorry: once a device has been authorised for a particular iTunes account you can't change it to another until 90 days have passed. This is to prevent people cirumventing the restrictions of purchases to one account from consteantly swopping between accounts. You will have to wait for the 82 remaining days, and there is no workaround.

When i try to watch one of my movies in the cloud it says "this computer is already associated with an apple ID.You can download past purchases on this computer with just one Apple ID every 90 days. This computer can be used with a different Apple ID"

my mom used my computer to sign into her itunes account and then i logged back into mine and tried to watch one of my movies and it said "this computer is already associated with an apple ID.You can download past purchases on this computer with just one Apple ID every 90 days. This computer can be used with a different Apple ID in 68 days" What do i do?

You do what it says.

Is there a way to get around the pop up, "this device is already associated with an Apple ID. You can download past purchases on this device with just one Apple ID every 90 days. This device can be used with another Apple ID in 13 days."Someonehelp please

What exactly are you trying to do?

You can download past purchases on this computer with just one Apple ID every 90 days. This computer can be used with a different Apple ID in 71 days. Whats the deal???

You can use multiple AppleIDs to purchase new music but you are limited as to how frequently you can change authorizations for re-downloading past purchases. It may well be a measure to deter piracy by stopping a group of people from going around to a friend's computer and downloading purchases on the other person's computer. It is easy to avoid by making sure you have backup copies on drives at home so you never need to redownload anything.

You can download past purchases on this computer with just one Apple ID every 90 days. This computer can be used with a different Apple ID in 60 days. This is the message I get when trying to view purchased material! My ID hasn't changed!

I can't pull up purchased content without this - You can download past purchases on this computer with just one Apple ID every 90 days. This computer can be used with a different Apple ID in 60 days. - my ID hasn't changed

I have airport extreme and just purchased a D-Link DCS-932L home network camera. D-Link says I need UpNp but the extreme doesn't support this. Can I use port mapping? if so anyone know how to set that up? thanks

I have airport extreme and just purchased a D-Link DCS-932L home network camera. D-Link says I need UpNp but the extreme doesn't support this. Can I use port mapping? if so anyone know how to set that up? thanks

Since the D-Link DCS-932L is accessible on the local network via a web browser, you should be able to access this camera from the Internet if your router has a publically accessible Public IP address. If your ISP provides you with a dynamic Public IP address, you may want to use a DDNS service to make it easier for you to locate your camera whenever your ISP changes your IP address.
Start the AirPort Utility > Select the 802.11n AirPort Extreme Base Station (AEBSn).
Select Manual Setup.
Verify that Connection Sharing = Share a public IP address is selected on the Internet > Internet Connection tab.
Select Advanced, and then, select the Port Mapping tab.
Click the plus sign to add a new port mapping.
For Service, leave the default; this will change to "Custom" once you start entering port values.
In the Public UDP Port(s) and Public TCP Port(s) boxes, type in a 4-digit port number (e.g., 8888) that you choose. In the Private IP Address box, type the internal IP address of your camera. In the Private UDP Port(s) and Private TCP Port(s) boxes, enter the appropriate port values that should have been provided to you by the camera manufacturer. Click Continue.
In the Description box, type a descriptive name like "Internet Camera Access," and then, click Done.
Click on Update.
To connect to the shared Camera from a remote location using a Mac or PC:
Start your favorite web browser.
Enter either your Public IP address or DDNS-provided Domain Name, followed by a colon and the Public port number that you choose in step 7 of the previous procedure. For example: http://123.123.123.123:8888 or http://www.mydtdnsdomainname.com:8888

If a computer has been associated with a device (as well as iTunes Matct, it can become associated via automatic downloads or re-downloading past purchases) then you will either need to wait until the 90 days have completed : http://support.apple.com/kb/HT4627
Or you can try contacting iTunes Support and see if they can remove the association : http://www.apple.com/support/itunes/contact/ - click on Contact iTunes Store Support on the right-hand side of the page

Unless you really only have one AppleID that you use with the iTunes Store there's really nothing you can do. In the case of having only one AppleID you should contact iTunes Store support, since that would be a server-side problem.

I just tried to connect and sync my iTouch (4G) to iTunes and I got an error message that said :This iPod can'be used because Apple Mobile Device service is not started". I tried searching my PC for the program and no luck. Any suggestions?

How can I use JNI in JDeveloper???

hi
I have a native mathod,it can work very well use JCreator or JDK's Java command.
But it can't work in Jdeveloper with the errors :
java.lang.UnsatisfiedLinkError: no JniConvert in java.library.path
void java.lang.ClassLoader.loadLibrary(java.lang.Class, java.lang.String, boolean)
void java.lang.Runtime.loadLibrary0(java.lang.Class, java.lang.String)
void java.lang.System.loadLibrary(java.lang.String)
void myInterMediaPackage.ArithmaticBean.<clinit>()
void DrawTest.init()
void DrawTest.main(java.lang.String[])
Who have used JNI in JDeveloper or can help me?
I appreciate anyone's help;

Dennis ,
Thank you very much.
I have resolved that question according to your second option.
thank you again!
Good luck.
2 options, that I know of (windoze, right?):
1. Add "-Djava.library.path=c:\<blah>\" (the location of your native DLL) to the "Java Options:" field in the "Project Settings/Configurations/Development/Runner" window. OR
2. Put your DLL in a folder that is on your PATH (e.g., c:\winnt\system32).
If you deploy it to a jar, and put the DLL in there, I'd think it would see it - but I haven't gotten THERE, yet! :-P
Later.

Can I use JNI with C#?

Hi,
I read many tutorials about using JNI with C or C++. Now, I wonder if actually JNI can also be used with C#? I have my machine installed with C# and Java. I really wanna learn about JNI but don't think to install C or C++.
If it's possible, can someone provide me some examples?
Regards,

I think you would need to write a JNI bridge in C++ that would call your C# code. If your C# code is exposed in .Net web services you could use that avenue instead.

How do I exit a java program based on condition can i use system.exit

I have java program that is called by another program that I dont have control on. My program returns a bigdecimal... but if the ordernumber is empty in my program i dont wnat to do anything.. does system.exit work in that condition... i put it int he else if ordernumber is empty condition.. but i dont think that is the right approach..

When software module is expected to bring some result, it should bring the result, positive or negative. I think you should check what your counterpart software expects as positive or negative result. And then implement your software this way. You can use System.exit, but this call is employed usually to indicate status with the software after it's completion and not to return any resulting value.

Under this condition, can I use JNI?
