Thanks.
the fllowing is my card:
Samsung S1
Model:TiEx-32J
EEPROM size:32k
Platform Version:OP 2.0.1
Card Manager Status:OP_READY
KMC:40~4F/No derivation

If you look around the forum for a bit, you will see that there is no notion of file systems on JavaCards (lexdabear posted this information less than two hours ago :-)). To store files, you will have to write an applet to hold byte arrays of the required size and handle receiving and sending of these.
As for documentation, you should have a look at the GP (General Platform) specification at http://www.globalplatform.org/, which defines communication between smart cards and other devices, as well as Sun's own JavaCard pages (http://java.sun.com/products/javacard/), which contain several useful resources on JavaCards.

  • How to create files with read/write privileges for everyone?

    I have two iMacs 7,1 (one with Snow Leopard and the other with Mountain Lion) in a local area wireless network.
    I have shared the "documents" folder in the Snow Leopard iMac in order to have files available to the other iMac. The folder has read/write privileges for everyone.
    When I create a new file in the shared "Documents" folder (for example a new Open office document, or a Keynote presentation) this file is by default "read/write" for the Administrator but only "read" for all the other users, so when I try to open it from the other iMac, I am informed that the file is "read only".
    I can obviously change the privileges of the file in the information window, but I have to do on a file per file basis and this takes too long.
    Is it possible to change settings in order to create files which are always "read/write" for everyone?
    And, secondly, since I have several existing files whose privileges I should manually change one by one, is it possible to make global changes of their privileges?
    Thanks in advance
    Best regards

    couple of different changes - 1st, if you want to share folders, doing your whole documents folder is not the best way.  Since both your computers can handle AidDrop, that's what I would recommend - http://osxdaily.com/2011/11/14/how-to-use-airdrop-in-mac-os-x/ - as it create an instant Ad-Hoc network between the two computers and then let's it done. 
    A second possibility that may not be what you're looking for, is to use google drive or some similay cloud sharing app to sync the documents back and forth.  both of these solutions will transfer the files well, but the airdrop may be simplest

  • How to creating file with APD (tcode rsanwb) with Key and Test characterist

    Hi everybody!
    I'm creating an APD with RSANBW. Data Source is a query and Data Target a File. I want display Key and Test for everyone of query characteristics. I've revised properties of characteristics into the query rows and check "key and test", however the file only contains key values.
    Some help will be very appreciated,
    Regards,
    Sebastian.

    Hi Sebastian
    the data  the query pulls is from the cube/DSO, which stores only the key.
    the query pulls the text from the master data tables for diplay purpose only. For APD purpose the query only supplies what is avaialable in the infoprovider.
    To have key and text in the target file you neeed to use transformation type routine in the APD or create an infoprovider that stores both text and key as separate fields in it and use that for the APD, with or without a query.
    Good luck,
    vijay

At the moment when I create a file using Word it is apparently given the extension .docx but Word doesn't recognise its own files. How do I allocate the extension .docx to Word? There used to be a way of doing it, I think under "Preferences" but I can't seem to find it.

  • How to create database with ASM

    HI
    How to create database with ASM?
    I install vmware workstation on window XP .On virtual machine install Linux 5 enterprise (Oracle) install.
    I install oracle DB software only. Also make 3 disk for ASM .
    1 -- When I want to install oracle DB with ASM . In this process candidate disks not show . Why?
    How I can see disks ..
    so I simple install oracle DB software only.
    2 -- Now I want to create database with ASM by DBCA .
    What process I will follow ?
    Please guide me
    Thanks

    Hi
    Steps to create database with ASM.
    1.Install oracle binary with active CRS(For single node installation CRS is activated when you run root.sh) .
    2.Create disk without file ssytem.
    3.Assign disk to raw .
    4.Change owner and permission to raw devices.
    5.Configure ASM manually or USing DBCA.
    Manually ASM Configuration.
    a.Create initialization parameter file and password file.
    b.Mandatory parameter is "instance_type=asm" as per your need configure rest of parameter like db_cache_size,large_pool_size,processes,remote_login_passwordfile,shared_pool_size etc..
    c.To discover disk configure "asm_diskstring=/dev/raw/raw*"
    Using DBCA to configure ASM.
    1.In storage type section choose ASM.It will ask for password of sysdba in 10g.
    2.ASM configuration window will open -> here it create disk group -> it shows all available ASM candidate disk automatical -> choose normal redundancy,external redundancy or high redundancy.
    ASM disk also can be conbfigured with ASMLIB .
    If ASM disk is configured you can start asm instance in nomount state and query to v$asm_disk to see all candidate disk.V$asm_disk only shows disk which is configured in asm_diskstrings.
    Hope this will help U,

  • How to creat javadoc with userdefine methods

    hi
    how to creat javadocs with user define class && methods ....
    we did like that
    javadocs filename..
    we are not geting my oun methods..
    pls help me
    regards
    kedar

    Hi,
    javadoc creates documentation for packages, not for single files - and you have to comment out every class, method, fields in a special form using javadoc tags - an example
    package MyPackage;
    import java.util.Vector;
    * This class is only an example, how to create javadocs for a package.
    public class MyClass extends Object {
    * an example for a public field holding a Vector
    public Vector aVector = new Vector(3,3);
    * Constructs a MyClass instance.
    public MyClass() { super(); }
    * Constructs a MyClass instance using the passed Vector in the {@link aVector} field.
    * @param vec a Vector, that replaces the Vector in field {@link aVector}
    public MyClass(Vector vec) { super(); aVector = vec; }
    * gets the Vector in field {@link aVector}.
    * @return a Vector, held in field {@link aVector}
    public Vector getVector() { return aVector; }
    }// end of classNow you can create your javadoc from the classpath with "javadoc MyPackage"
    hope, this helps
    greetings Marsian

    I read the following topics and help:

    2. Re: How can we transfer billing documents from SAP ERP to CRM 2007?
    3. http://help.sap.com/saphelp_crm70/helpdata/en/46/029ba32e675c1ae10000000a1553f6/frameset.htm

    2. Assign Business Object Types to Transaction Types

    but still do not know,
    1) if I should pre-replicate billing documents into CRM ?
    2) Or, the system uses the RFC to find these documents in ECC to create reference?

    Hi,
    SE38 -> Enter program
    Select Variants button and display. In the next screen, enter a variant name, (If not existing , press Create to create new one), else click on Change.
    Now the selection screen will display with a button "Variant Attributes" at the top.
    Click on that button.
    In the next screen, go to the selection variable column of the date field. Press F4 or drop down and select 'D' for date maintenance.
    In the column "Name of Variable (Input Only Using F4)" press F4 or drop down, select whichever kind of date calculation you want and save the variant.
    Now whenever you run the prgrm with this variant, date will be displayed by default.
