What is used in place of skeleton interface?

So in Java 2 SDK, Standard Edition, v 1.2 the skeleton interface was deprecated - i.e. should not be used since it will eventually be removed.
So what on the server side allows for the marshalling and unmarshalling of objects? Is it RemoteObject or RemoteServer or some proprietary (i.e. differs with different JVM's) derived class from the above two? I'm just wondering because on the client side it is obviously the Stub class that handles this - so who is the counterpart to the Stub class on the server side?
Thanks,
Novice

There's an extensive server-side runtime system which
listens at sockets, accepts connections, reads
incoming call headers, unmarshalls arguments,
dispatches calls, marshalls return values and
exceptions, and writes these to the socket. Does anyone know of what classes are involved in the socket handling? I can decompile the stub class and see that it is using RemoteCall to invoke the remote methods.
Thanks,
Novice

  • What to use in place of Flash

    I'm trying to make a sliding, Ken Burns effect with photos for a website. What can I use in place of Flash that will work on an iPad?

    In general, HTML5 is the expected/preferred path. You can do numerous animations/transitions in HTML5 with a few lines of CSS and/or JavaScript.
    A quick search for HTML 5 transitions turns up lots of candidates.

    Marker Interface Pattern
    The marker interface pattern is a design pattern in computer science.
    This pattern allows a class to implement a marker interface, which exposes some underlying semantic property of the class that cannot be determined solely by the class' methods. Whereas a typical interface specifies functionality (in the form of method declarations) that an implementing class must support, a marker interface need not do so. The mere presence of such an interface indicates specific behavior on the part of the implementing class. Hybrid interfaces, which both act as markers and specify required methods, are possible but may prove confusing if improperly used.
    One good example of a marker interface comes from the Java programming language. The Cloneable interface should be implemented by a class if it fully supports the Object.clone() method. Every class in Java has the Object class at the root of its inheritance hierarchy and so every object instantiated from any class has an associated clone() method. However, developers should only call clone() on objects of classes which implement the Clonable interface, as it indicates that the cloning functionality is actually supported in a proper manner.

    If you know that you will not be asked to design GUI interfaces, and the C programming course will adhere to command line compilation environments, then get the Xcode command-line developer tools, and skip the extra complication of Xcode until you absolutely need it. Apple has kicked GNU C to the curb and is rightly so, using Clang/LLVM compiler technology.
    Sign up for a free Apple Developer account using your Apple ID, and then visit the Mac Dev Center, and towards the bottom of the page, you will see additional downloads. Click on the associated, all down loads link. Know your OS X version beforehand, as the command-line tool releases are tied to general operating system versions, and the most recent Xcode version.  That said, there are currently two March 9, 2015 command-line tools for Xcode 6.2 — one for OS X 10.9 Mavericks, and the other for OS X Yosemite.

  • What program can I use in place of Flash?

    I have tried using several programs that need Flash, of course Apple doesn't support it.  Is there another program I can use in place of Flash?

    Apple doesn't want and Adobe have never made a version that works on iOS devices anyway.
    As you don't say what you have tried I don't know whether they include browser apps such as Skyfire, iSwifter, Puffin and Photon, which 'work' on some sites (but judging by their reviews not all sites). Also some websites, especially news sites, have their own apps in the App Store.

  • Why interface property be default final whats the use of that

    can anybody explain me
    when i declared a variable inside the interface its always public static final.
    why its static and final what the use of theat. its set of rule or it has any reason.

    Sir,
    You do not have much choice:
    From the JLS (9.3):
    "Every field declaration in the body of an interface is implicitly public, static, and final. It is permitted to redundantly specify any or all of these modifiers for such fields."
    Note from this though that you do not have to explicitly declare a field in an interface as public / static / final if you dont want to - if you leave it out the field is implicitly declared with these attributes.
    So you could wite:
    public interface SirInterface {
      public int HeIsActuallyPublicStaticFinal = 1;
    }

  • What to do if you use a segmented control in interface builder and it doesn't work ?

    What to do if you use a segmented control in interface builder and it doesn't work ?

    The first thing to do would probably be to update your profile and/or signature so people will know what OS, language, and development system you are using, then perhaps include some additional information such as what "it doesn't work" means, and possibly a few other things like some error logs, what you have done so far, maybe a code snippet or two, etc.

  • What is the diffrence between My Runnable Interface and Java Runnable

    Hi folks
    all we know that interfaces in java just a decleration for methods and variables.
    so my Question is why when i create an interface its name is "Runnable" and i declared a method called "run" inside it.then when i implements this interface with any class don't do the thread operation but when i implement the java.lang.Runnable the thread is going fine.
    so what is the diffrence between My Runnable Interface and Java Runnable?

    Hi folks
    all we know that interfaces in java just a decleration
    for methods and variables.
    so my Question is why when i create an interface its
    name is "Runnable" and i declared a method called
    "run" inside it.then when i implements this interface
    with any class don't do the thread operation but when
    i implement the java.lang.Runnable the thread is going
    fine.
    so what is the diffrence between My Runnable Interface
    and Java Runnable?
    thnxClasses and interfaces are not identified by just their "name", like Runnable. The actual "name" the compiler uses is java.lang.Runnable. So even if you duplicate the Runnable interface in your own package, it's not the same as far as the compiler is concerned, because it's in a different package.
    Try importing both java.util.* and java.awt.* (which both have a class or interface named List), and then try to compile List myList = new ArrayList();

    I’m having an intermittent problem with my midi controllers triggering Mainstage 3.
    I’m using a PreSonus Firebox audio interface.
    It’s been working fine for months, but now when I first turn on the computer in the morning , I’m not able to trigger MainStage from the keyboard.  I tried different midi controllers, different keyboards, different midi cords, and check midi preferences.  The audio interface is working fine and is recogonized, but the midi doesn’twork.  I re-started the computer several times and then finally it miraculously starts working again.
      I’ve been having to this every day now.  Any help or ideas is very much appreciated.

    I Had the same problem with a FireStudio. Try unplugging the FireWire plug and the power plug. Wait for a few seconds, then plug both back in. The light on my FireStudio was flashing blue/red which means "not connecting." I did what I just described, and everything works again. Hope it works for you.

    Hi Majid,
              It's a function module to read the texts from a text file. Generally it is used to retrieve the long texts.
    The function module reads the desired text from the text file, the text memory, or the archive. You must fully specify the text using OBJECT, NAME, ID, and LANGUAGE. An internal work area can hold only one text; therefore, generic specifications are not allowed with these options.
    After successful reading, the system places header information and text lines into the work areas specified with HEADER and LINES.
    If a reference text is used, SAPscript automatically processes the reference chain and provides the text lines found in the text at the end of the chain. If an error occurs, the system leaves the function module and triggers the exception REFERENCE_CHECK.
    CALL FUNCTION 'READ_TEXT'

    Reference field: SY-MANDT
    Default value: SY-MANDT
    OBJECT
    Enter the name of the text object to which the text is allocated. Table TTXOB contains the valid objects.
    Reference field: THEAD-TDOBJECT
    NAME
    Enter the name of the text module. The name may be up to 70 characters long. Its internal structure depends on the text object used.

    Enter the text ID of the text module. Table TTXID contains the valid text IDs, depending on the text object.
    Reference field: THEAD-TDID
    LANGUAGE
    Enter the language key of the text module. The system accepts only languages that are defined in table T002.
    Reference field: THEAD-TDSPRAS
    ARCHIVE_HANDLE
    If you want to read the text from the archive, you must enter a handle here. The system uses it to access the archive. You can create the handle using the function module ACHIVE_OPEN_FOR_READ.
    The value '0' indicates that you do not want to read the text from the archive.
    Reference field: SY-TABIX
    Default value: 0
    Import parameters:
    HEADER
    If the system finds the desired text, it returns the text header in this parameter.
    Structure: THEAD
    Table parameters:
    LINES
    The table contains all text lines that belong to the text read.
    Structure: TLINE
    Exceptions:  
    ID
    The text ID specified in the parameter ID does not exist in table TTXID. It must be defined there together with the object of the text module.
    LANGUAGE
    The parameter LANGUAGE contains a language key that does not exist in table T002.
    NAME
    The parameter NAME contains the name of a text module that does not correspond to the SAPscript conventions.
    Possible errors:
    The field contains only blanks.
    The field contains the invalid characters ‘*’ or ‘,’.
    OBJECT
    The parameter OBJECT contains the name of a text object that does not exist in table TTXOB.
    NOT_FOUND
    The system did not find the specified text module.
    REFERENCE_CHECK
    The text module to be read has no text lines of its own but refers to the lines of another text module. This reference chain can include several levels. For the current text, the chain is interrupted, that is, one of the text modules referred to in the chain no longer exists.
    WRONG_ACCESS_ TO_ARCHIVE
    The exception WRONG_ACCESS_TO_ARCHIVE is triggered if an archive is accessed using an incorrect or non-existing archive handle or an incorrect mode (that is, read if the archive is open for writing or vice versa).

  • What is '&' used in message class

    Hi,
    What is '&' used in message class with the message no in SE91.
    Give me details idea on this.
    Best Regards,
    Chini

    If you use '&' operator in your message, then you can pass the text/literals whatever you want to get display in the message.
    For example,
    In a message clase zmsg, there is a message like this...
    018 Table & not exist
    you can call this message from your program by passsnig the table name in to this message...
    For example,
    ztablename = 'BUT000'.
    Message e018(zmsg) with ztablename.
    Filling Message Texts Dynamically *
    Message texts in table T100 can contain up to four ampersand characters (&) as placeholders. You can replace these at runtime using the WITH addition in the MESSAGE statement:
    MESSAGE ... WITH f1 ... f4.
    The contents of fields f1 ... f4 are then inserted sequentially into the message text in place of the placeholders.
