How to read particular Sector and Block in Mifare 1k through Java?

Hi Friends..
Do you know how to read particular Sector and Block in Mifare 1K through Java?..
I've created the simple application that read data from Mifare 1K, but i've problem when i want to read the other sectors and blocks..
i tried to read the blocks by using this APDU command :
FF B0 00 00 10 //read data in Sector 0 and Block 0
FF B0 00 01 10 //read data in Sector 0 and Block 1
FF B0 00 02 10 //read data in Sector 0 and Block 2
FF B0 00 03 10 //read data in Sector 0 and Block 1How to read the other sectors and blocks?..
I've tried to read data in Sector 1 and Block 5, so i tried to send this APDU command : FF B0 01 05 10, but i got this error : *6986*
Actually, it doesn't matter if i use MifareWnd, but i want to create my own application that Read/Write From/into Mifare 1K..
Please help me regarding this..

Getting result from a telnet command through Java

Hi,
I've been using a set of classes found here: http://javatelnet.org/
to do telnet through Java in a non-interactive mode.
However I've got a problem when retrieving the result of a command sent to the remote host: the classes read the stream until the prompt is encountered; my problem is I must execute commands on several remote hosts, and the prompt is not necessarily the same on all hosts.
Is there a simple means to establish a telnet connection through Java and retrieve the result of the commands?
Any help would be appreciated.

Thanks again, this is a very good article
I see it is still the same strategy to get the result of a command : wait 'til the prompt is sent. Maybe there is just no other way to get it .
But as I don't know the prompt on the different hosts I have to query, this won't do it.
The article gave me an idea though : I only need to count the files in a directory on the remote host; until now I was trying to send the 'ls | wc -l' command by Telnet.
Maybe I can simply do it by FTP (retrieve the list of files, and then count the lines with JAVA).

What is the best way to call SSH commands through Java technologies

What is the best way to call SSH commands through Java technologies

I don't think you can specify the password at the prompt using ssh. Plink has the -pw command option for passwords. What I did was except ssh to ask me and write the password programmatically through the outputStream I obtained from my Process object. I looked for "password: ", and then wrote the password with a trailing newline.
Both plink and ssh will also ask if you trust the host if it is the first time you are connecting to it. So before just writing the password, check if the program wants verification from you: normally supplying "y" or "n". This should only have to happen the first time the client connects. It looks like thisPLINK:
The server's host key is not cached in the registry. You
have no guarantee that the server is the computer you
think it is.
The server's key fingerprint is:
1024 f8:43:61:4c:a2:5b:77:be:5b:a7:bb:1f:f7:79:b3:b7
If you trust this host, enter "y" to add the key to
PuTTY's cache and carry on connecting.
If you want to carry on connecting just once, without
adding the key to the cache, enter "n".
If you do not trust this host, press Return to abandon the
connection.
Store key in cache? (y/n)
SSH:
The authenticity of host '127.0.0.1 (127.0.0.1)' can't be established.
RSA key fingerprint is e1:02:13:c8:52:c2:23:41:9b:5b:58:2c:18:e6:59:af.
Are you sure you want to continue connecting (yes/no)?What I did was read character by character from the inputStream until I found things of interest ... like "password: ". You only need to search for this in your method which will launch the ssh or plink Process. Once you have verifyed yourself, you can just pass commands to the Process, which is an ssh connection.
My suggestion is to read() each byte from the Process's inputStream and write it to stdout. Look and see what you need to be looking for so you can interactive with the program correctly. You can't use readLine here becuase when the ssh asks for the password it does not print a newline. I do know for sure, that ssh will simply print, "passowrd: ". Plink will print this as well if the -pw option is not supplied.

Hardware information thru Java prog

Can anybody provide me the information about how in Java one can retreive information regarding Hard disk serial number, free space, total space of hard disk etc through Java programming. It is possible in Visual Basic and I am sure there must be some method to get this info in Java.
I would also like to know various other utilities/methods thru which one can communicate with system hardware

To access hardware you must to use native methods ie your java application must to invoke some native library (DLL's in Windows) because this issue is OS dependent. There is an Java API specially dealing with this topic: JNI (Java Native Interface).

How to use hardware acceleration in Java 2D

Hi,
I searched in net and could not find anything clear on hardware acceleration using Java 2D/Swing.
To use the hardware acceleration, do I need to specify
-Dsun.java2d.opengl=true ? Is this must?
Without specifying this, Java 2D calls wont use hardware acceleration?
Kindly clarify. I could not able to find anything in net for this.
I am having ATI Radeon AGP card and using Linux as OS. I have installed the ATI driver. Now I need to know how to interact with hardware using Java2D/Swing.

Error while running executable file through java in WinNT

I would like to run an executable file with Java.
- If I try with notepad or paint, i.e. Windows Applications,
  I have no problem.
- I also can run Non-Windows-Own Applications, except one.
  I get an error message, if I want to run this program through Java.
I have tried following commands to run an executable file.
Runtime.getRuntime().exec("cmd.exe /c "+command);
Runtime.getRuntime().exec("cmd.exe /c start "+command);
Runtime.getRuntime().exec("cmd.exe /c start /wait "+command);
Runtime.getRuntime().exec("cmd.exe /k start "+command);
command : the path to the executable file
I can run the application directly, if I click the icon on desktop,
but not through Java.
here is the error message I get
screenshot : http://www.aykut.de/error_message.jpg
Text : "Security Check failure"
        The Logon System has been tampered with.
        The Administrator will need to re-install.
my Idea :
The application is "old".
I think it was written for Win 3.1.
Therefore I don't know if there is any other
possibilty to run a "DOS Exe File" through Java.

I have just figured out how it works,
if somebody else here in forum have this problem,
here is the solution :
String path = "F:\...\...\Application.exe";
String envDir = path.substring(0, path.lastIndexOf("\\"));
String[] command = {"cmd.exe", "/c", "start", "/wait", "/D"+envDir, path};
Process process = Runtime.getRuntime().exec(command);
"start /Dpath" => path: environment directory F:\...\...\
"start /wait" => wait until Application.exe terminates
if you use Win95 or Win98 use command.com instead of cmd.exe

Issue with sending mail through java stored procedure in Oracle

Hello,
Thanks for the reply. Actually I have seen that post before creating this thread. I thought that I could make use of java mail to work around this problem. I created a java class that succesfully sends mail to SSL host. I tried to call this java class from pl-sql through java stored procedure. That did not work
So, is this not supported in Oracle ? Please note that I have tested this in both 9i and 11g , in both the versions I got the error. You can refer to the code in the above post.
Thanks

please help me,its very urgent.

come back in about 5 years, we may have time for you by then.
In the meantime, how about contacting the people who wrote that library and asking them nicely for help (rather than trying to order people to drop whatever they're doing and jump through hoops to accommodate your every wish as you're doing here)?
