Hi small doubt on network app?

Hi we have developed an app in java which works on LAN. But according to new requirement we need to run that app on LAN which is established via WIFI. I mean all the systems connect to LAN using WIFI. So is there anything special that we have to do to make the app run on the WIFI LAN?

I am not sure but i think the network protocol(collision detection etc) will be implemented by OS By the TCP/IP networking stack, inside the OS.
and then then the tcp/ip is implemented by sockets. Am i right?Not so much right as meaningless. A socket is an endpoint of a TCP connection, or a UDP endpoint.
as far as i know networking is a concept. if it has to be established there should be a protocol well implemented. One such protocol is WIFI which makes the systems to establish LAN. Please correct me if i am wrong.I don't really np know what all this is supposed to mean or how it affects your project, whatever that is. Perhaps you could ask a specific question?

  • StreamCorruptedException : invalid Type Code AC .. In case of a network app

    Hi
    I am developing a peer-peer application here.
    What i have is a client and a server on each user, both running parallell.
    User A sends an object to User B through an ObjectOutputStream through the main thread.
    User B reads it using an ObjectInputStream and passes the object that it read, to a new ObjectOutputStream, to be passed to User C.
    User C just reads the incoming object using ObjectInputStream.
    This iteration runs successfully for the first run!
    The moment I go for the second iteration using User A, the method on User B throws a "invalid type code AC".
    class Main{
    Socket sock;
    psvm(String args[]){
    Client newCli = new Client();
    newCli.setSock(<Sets the sock after getting the port and IP address from the user>);
    sock = newCli.getSock();
    ObjectOutputStream oos = new ObjectOutputStream(sock.getOutputStream());
    oos.writeObject(new Client());
    Class Server extends thread{
    public void run(){
    while(true){
    ObjectInputStream ois = new ObjectInputStream(sock.getInputStream());
    ois.readObject();
    I read through this post on this forum and "EJP" asks that one OOS and one OIS be maintained per socket.
    So what i did was add a setter method to the Client class which stores the Socket, and called the setter method instead of creating a new ObjectOutputStream object everytime. This way one ObjectOutputStream object would be maintained per socket per client class's instance.
    class Client{
    Socket sock;
    ObjectOutputStream oos;
    //Getter and setter for sock.
    getSock()....
    setSock()....
    //Getter and setter for ObjectOutputStream
    getOos()....
    setOos(){
    oos = new ObjectOutputStream(getSock().getOutputStream());
    When i do this, the initial iteration itself fails.
    I am posting the outline of my code since it is a big file. But if writing out a smaller version of the app and posting it here will help better understand the scenario, then I'll do it.
    I am re-posting this, coz in the previous posts regarding this same issue, i found that people were writing and reading on the application. While mine is a case of a client-server send and receive.
    I am just writing multiple times at the client and reading multiple times at the server. And each time i'm creating a fresh ObjectOutputStream object, and Client object.
    I don't close the streams since that closes the sockets, but i need to keep the sockets open and send multiple objects on the same socket.
    The explanation is a bit lengthy, so let me know if something is not clear. :)
    Thanks
    Akshay

    I'd be grateful if someone can throw some light on this issue, i have to get beyond this ASAP, and i cannot find a workaround at all.. :/

  • Share Image,Link and Text to Social Networking App from My Windows Phone App

    Hi,
    I am developing windows phone 8.1 silverlight app where I want to share Images,Links and text to Social Networking App Like Facebook,Twitter,Whatsapp and Instragram.
    In Share content contains A Image of App Icon, A Link of App website and I invitation Text.
    There are Five buttons
    Share by Email
    Share by Facebook
    Share by Twitter
    Share by Whatsapp
    Share by Instragram
    Problems which I faced
    I can not attached image to Email. How it is Possible.?
    I can only open whatsapp from my App. But can not share to this
    I have used Share task but in list of app there is no whatsapp and instragram app ( I know there is no official app for instragram but it is Instragram Beta app)
    Please guide me how can I share my content to all above app

    Please see this sample application:
    https://code.msdn.microsoft.com/windowsapps/Sharing-Content-Source-App-d9bffd84
    You cannot control what appears in the share UI.  The Share UI Will show all applications that have registered to receive the type of content you are sharing.  So if a particular application is not appearing, then it is not registered as a Share
    target for that content type.
    I would run the sample on your phone for the various content types.  it should give you a good idea of which apps are registered for which content type.

  • The Social Networks app for N8 needs an update

    The social networks app for N8 is OK, but one very critical example is that you can't see notifications on facebook, which basically is one of the most important things, to be able to see how people have directly interacted with you.
    What's nice about an update like this is that it wouldn't need to be included in a firmware update, it could be a separate update for just this app.
    What do you think needs to be improved?

    Hi...
    Tap Settings > General > Reset > Reset All Settings
    You won't lose any data or media as a result of a reset.
    If that didn't help, tap Settings > General > Reset > Reset Network Settings then restart your iPad.
    Hold the On/Off Sleep/Wake button down until the red slider appears. Slide your finger across the slider to turn off iPhone. To turn iPhone back on, press and hold the On/Off Sleep/Wake button until the Apple logo appears.

  • Small doubts regarding devices and permissions

    Hill all,
    Continuing with my experiences with Oracle 11gR2 and Solaris 11, i came up with some "small" doubts regarding the permissions and owners of the devices to be used as ASM diskgroups. I was able to install Grid and the database, both 11.2.0.3.0, in a single-instance configuration, but i had a small issue when creatind the diskgroup for the database data (+DATA). I created 3 devices (VirtualBox) to be used in the +DATA dg, and gave the the "oracle:dba" owner, with the permission 660. My doubts are:
    1) It wouldn't be more correct to make the owner of the device the user grid? (grid:dba)
    2) The permission 660 to the devices is the correct, or recommended permission? It did work with this permission.
    Thanks in advance.

    It depends on the user and group that runs the ASM instance. It can be oracle/dba, but can also be a different user, e.g. grid/asmadmin
    http://docs.oracle.com/cd/E11882_01/install.112/e22489/storage.htm#CHDFAGJD
    660 means rw. That should be ok. No other user/group than the ASM instance needs to access the devices.

  • It's s small local area network I'm looking to create.

    Hi
    Can some one point me in the right direction please.
    I have 32 G5 machines running latest OS I'm fed up with my IT department not being able to help with the smallest of issues.
    I want to be able to connect all my machines together have a shared folder system be able to get work of one machine to another create accounts for all staff and have a reasonable shard volume some place to hold backup files. Not much to ask is it.
    I need a server of some sort and some way of managing the server, but which one and how big.
    It’s s small local area network I’m looking to create.
    Just start me off in the right direction some one please.
    Or can I use one of the G5’s to manage all the machines with server software installed on it? If I can how do I join all those wires to one Mac?

    Hi jegoadby,
    Welcome to the forums... you are in the right place.
    I suggest OSX server is what you need. An Xserve would be ideal. You could just buy the OS X Server software and run it on one of your G5's (though that Mac would need to be dedicated to the job and not used by anyone for day-to-day work).
    Your strategy will depend on the current IT architecture of your organisation, and how much you need to play within that architecture, eg. DHCP, DNS, Printing services. Easiest for you woud be to create your own network of just your Mac machines & server.
    To give you an idea of what this will involve check out Appendix B, 'Mac OS X Server in a Small Business' example, of the Getting Started PDF at:
    http://www.apple.com/server/documentation/
    Please come back with any specific questions.
    hth,

  • Urgent--- small doubt

    Hi
    I need some docs for 8i installation on win2K. Also I've a small doubt.... I want to move one database (8.1.7.4) to a new server. On this new server I have to install Oracle 8.1.0...... Now the doubt is if I do backup/restore from the old server, do I still have to apply patch 4 on the new server???
    Any input is appreciated.
    Regards

    Hi,
    I suggest you apply the patch becuase the database backup has the version info which is 8.1.4. Thus when you will use the 8.1.0 Oracle kernel to start a 8.1.4 database then it might give an error. It is best suited to apply the patches in the new server the way it is in the old one. Once you have applied the patches in Oracle kernel (Oracle Software) you may go ahead with opening the database.
    This will keep the versions of the Oracle kernel and the version info in the database control file in sync.
    Regards.

  • IOS5 installed in iPad2, no "Fashion Network" App anymore.

    After I installed iOS 5 in my iPad2, the "Fashion Network" Application does not function anymore. The "Fashion Network" App. is suitable for iPad and iPod. In the iPod with iOS5 it functions well. On the iPad2 however the App. opens with the "Fashion Network" logo and is closing down shortly after. Removing and re-installing the App. does not solve the problem. With iOS4 the App. functioned well in the iPad2.The App. delivers HD movies (Catwalk Fashion Shows) on the iPad2 and SD on the iPod. A test with another iOS5 iPad1 gave a similar result (no Fashion Network). There seems to be a conflict between this App. in HD and iOS5!

    After installing iOS 5.1 the Fashion Network App did run again on the iPad. however at the end of the clip, the App stopped and has te be restarted.
