Screen Sharing Application

Hi,
I have to create a Screen Sharing Application in java. So I would like to know if it's possible to create a Screen Sharing Application in java and if it is, how can I start and where can I get information for it. Please is there anyone who can help me.
Thanks in advance!

the idea is to keep sharing my screen not just send a screenshot (e.g. if I watch a movie on my Pc then the client which is connected to me should be able to watch it too, like skype does)
Is that possible or could I do it by sharing a screenshot every millisecond?You don't need to send it every millisecond, that's way overkill. Find out what the frame rate of a typical movie is and use that rate as a more reasonable starting point.

  • I am looking for a Meeting/ Screen Sharing Application on iPad2 using which I can provide presentation/ screen sharing to other iPad or Windows PC.

    I am looking for presentation/ screen sharing application for iPad 2. Similar to WEBEX or GoToMeeting using which I can give presentation using an iPad.    

    For sharing between iPads, this might be worth a look:

    Cisco has a WebX application for the iPad that says it allows scheduling, hosting, and attending meetings. There is a client for GoToMeeting for iPad, but I believe that you can only attend, not host.

  • Can't find Screen Sharing application!

    I have looked everywhere but it is not there anymore!
    Can I download it again or has Apple hidden it?
    Please help

    There are certain directories not searched by Spotlight, I suspect as a safety feature to lessen the chances of accidentally deleting something important (like Screen Sharing app).
    While the Screen Sharing app is in the dock can you select "Keep in Dock" from its contextual menu?
    I didn't check.
    It may be that that option is not available as one needs to select a particular server rather than simply launching the Screen Sharing app by itself.

  • Remote desktop and screen sharing with RMI

    Iam developing an application for screen sharing and remote desktop
    the problem is a performance problem
    in the screen sharing application server screen is captured and the image is sent to all connected clients through rmi connection
    I used JPEGImageEncoder to compress the image and convert it to array of bytes
    then zipped the resulted array using deflater.
    the result is sent through rmi connection
    the performance is so poor
    i tried JMF but the performance is worse
    i am thinking of a way to send the server screen only if it is changed but i don't know how
    anyone could help me to enhance it with acceptable quality for the image
    thanks

    As you said, you need to only send the changes over the line.
    Java can not tell you what has changed, so you need to either write some JNI, or do a check on the current image, with the last image. (this would eat quite a bit of CPU time on the server).
    It might be worth looking at the source for VNC, and other simler products.
    The simpliest solution would be to split the image into blocks of x by y pixels, then do a pixel-by-pixel check on that block, and only send the block if it has changed.
    Next thing to think about is scrapping RMI, and using raw sockets. RMI has a fair sized overhead.
    Zipping a JPEG is unlikely to have any effect. A JPEG is already compressed.
    You might want to look at a lossless compression format, like PNG, as the JPEG will have articles. This might be acceptable. If so, changing the compression ratio of the JPEG might be an option.
    Finally, the bottle neck might be the call to Robot.createScreenCapture. This is not the fastest method.

  • After Lion install screen sharing won't accept my password

    I just updated my *headless* mac-mini to 10.7.  As soon as it rebooted
    Since updating to OS 10.7 on my Mac Mini, I have been unable to log in via Screen Sharing (using my 10.7 installed Mac Pro).  I continually receive the error "Authenticaion failed to 'MacMini'. Please verify you have entered the correct name and password."  The name and password are correct, and the mac-mini lets me "Connect As ..." with the username and password.  Only the Screen Sharing application fails to authenticate.  I had no troubles  an hour ago when it had Snow Leopard installed.
    Any solution before I have to travel to this mini?
    Thanks,
    Jim

    My family has multiple Macs at home and I also help a friend at a remote location.  What is weird, is I was able to do screen sharing with the Mac at the remote location and a couple at home, but was not able to get screen sharing to work on the majority of our Macs at home.  Rebooting did not help.  Deleting my user login and corresponding home folder (then rebooting) and recreating a new user under the same login name that was deleted did not help.  Repairing permissions in Disk Utility did not help.  I did not try creating a user under a totally different login name and setting up screen sharing to share with that user name.  I was going to try that this morning.  However, on another thread, someone offered another thing to try.  I tried it and it worked.
    This is what eventually worked for me...  This work around seems to expose that there is definitely a bug:
    https://discussions.apple.com/message/15812668#15812668
    Quote from andifor:
    "Full name and account name on my computers are also the same.
    But I did some deviation last time I tried. I changed my name on the connection dialog. I changed the name from "user" to "uSer" (changed one letter to capital) and it did work!
    So if you login name is "peter", change it to "pEter" or "peTer", just on the login screen.
    Looks more and more like a bug and only Apple can help. Does anybody know, if they are monitoring these discussions or is there a possibility to log some bug report?"

  • Screen Sharing: Authentication Failed

    Since updating to OS 10.7 on my Mac Mini, I have been unable to log in via Screen Sharing (using my 10.7-installed Macbook).  I continually receive the error "Authenticaion failed to 'MacMini'. Please verify you have entered the correct name and password."  The name and password are correct, and I can log into the computer as an administrator via the Finder to access its files without issue.  Only the Screen Sharing application fails to authenticate.  I had no troubles literally an hour ago using Snow Leopard.
    Thoughts?

    After restarting both computers a few times, I can now no longer connect via normal File Sharing -- it will connect as a guest just fine, but when I try to connect as a user, it stalls out.  It sounds like the problem in this thread:

  • Screen sharing questions

    Merry xmas everyone.
    I have a few questions I hope you can answer.
    I just discovered screen sharing between my mac mini and macbook laptop via a physical ethernet connection using a linksys router (no wifi).
    I go to the finder and see the other computer and click share screen, and it shows up beutifully. But without asking for a user name and password. I tried logging in from a guest account and it then asked me for a user name and password. So just to make sure for my peace of mind, both machines have the exact same user name and password (and .mac account), so is that the reason they can both connect to each other easily without the need to verify.
    Is this share screen even possible via wifi (using Finder and not ichat)? Or just via a hard line connection?
    2nd... is there a way to share the audio between both machines? My overall goal is to connect to my main computer from my laptop from my night stand so I can listen to my podcast, and have them marked as listened to, so that I don't have to wrestled with keeping two podcast libraries on two different machines sync to my ipod... ugh.
    plus i won't have to drop the extra cash on an ipod dock.
    Thanks
    have a great new year everyone

    1. While screen sharing is it possible to drag a document from the remote screen to the computer you are using?
    No, but if you use iChat as your screen sharing tool you can copy the file(s0 manually that way. In Finder you could also simply both screen share and mount the filesystem of the mac.
    2. Does screen sharing work over the internet (like web sharing)?
    Not using the direct screen sharing abilities. But if the mac you're trying to control is set up to be accessed from the internet (with afp://) then you should be able to enter that address into the "New..." menu item window in the screen sharing application. The application is at: /System/Library/CoreServices.

  • Keyboard lockout after screen sharing

    I was doing some screen sharing from another Mac on my LAN. There's no "disconnect" feature to stop the remote control, so I simply quit the Screen Sharing "application," closed all windows, and logged out of the controlling Mac.
    Problem is, at the target Mac, upon every other restart approximately, like this morning after software updating, the keyboard is locked out. Entire keyboard has no effect. Mouse control is okay. The other Mac wasn't touched for days, while this target Mac has been logging in and out just fine. The restart puts me in a state where I cannot type in my login password, and restarting (with mouse) brings me back to the same state, restart after restart. I don't think it has anything to do with the software update, but instead, some kind of residual control from the other Mac that was not fully severed upon quitting.
    Even after going back to the other Mac to remotely log into Finder via screen sharing, the keyboard in the target Mac is still like disconnected. Mouse control still okay. Same problem.
    Any solution?

    Entire keyboard is locked out EVERY TIME my Mac is restarted! Not just every other time. I mean NOTHING on the keyboard works when locked out -- like it's disconnected, but there's no physical disconnection.
    The iffy workaround that gets me back to normal, and only sometimes, is restarting via screen sharing from the remote Mac, then "closing" +Screen Sharing+ (it quits immediately), then quickly logging out of the controlling remote Mac. And THEN I still have to restart the target Mac several times to get lucky! For example, just now restarting five times did not work, but going through the gyration again + restarting twice got me back.
    Remote Mac = 2005 Powerbook 15" G4 running 10.5.5
    Target Mac = 2003 Dual 2GHz PowerMac G5 running 10.5.5
    This new phenomenon came about only after I used +Screen Sharing+ on the LAN.
    Help!

  • Unable to resize Screen Sharing screen

    Hi,
    I am seeing two issues with Screen Sharing when accessing a desktop Mac from a MacBook Pro with a 20in external monitor attached to the laptop.
    Using the Screen Sharing application to remotely control the Mac Pro when I connect the size of the Screen Sharing window varies, most of the time it is small (about half screen width and two thirds screen height) but sometimes it is almost full size on the monitor. The Fit Screen in Window button setting does not seem to affect this.
    Furthermore when I try and drag the bottom right hand corner to increase the size of the Screen Sharing window it will not allow the window size to be increased.
    In 10.5 Leopard the Screen Sharing app could be configured using defaults but Apple in their, err, wisdom, have disabled them it seems in 10.6 Snow Leopard. So...
    (1) Is there any way to make/configure the app to always display a maximized screen size when connecting to a remote Mac?
    (2) Why can I not resize the window by dragging the right corner using the standard Mac window resizing mechanism?
    Thanks.
    Tim

    Try playing around with the window positioning. There is no definite way to keep a window's size/position, but try playing around with it.
    I have dragged the window around but it makes no difference.
    (2) Why can I not resize the window by dragging the right corner using the standard Mac window resizing mechanism?
    You may not be able to make it bigger, but can you make it smaller?
    Yes I can make it smaller but when I drag to make larger again it stops at the original size and you cannot drag further.
    I noted that the screen resolution setting in the monitors preference pane of the Mac Pro had been set at 800 x 600 but it was set to 1680 x 1050 (the res of the 20in monitor) so perhaps Screen Sharing does not support that res and it gets reset when you create the connection?

  • Screen Sharing Disabled Per User?

    Hi, this is a repost from OSX usability forums...hopefully someone can help here:
    I caught a kid cheating this morning by utilizing Screen Sharing to see what his neighbor was answering on a test. I would like to disable Screen Sharing as it pertains to the user, but I still need to run Remote Desktop and see all machines at the admin level. Each kid has an OpenDirectory account, so would it be possible to block at that level?

    Block the Screen Sharing application. If the accounts are OD accounts, just add this to the MCX set and start enforcing an explicit deny on the Screen Sharing app. That should resolve it. The other option, assuming all systems have a unified admin account that the kids don't know, go into System Preferences > Sharing > Remote Management and choose "only these users" and add the local admin account only. That should set up a SACL for the ARD/Screen Sharing process to only allow access for the one user, not for all potential users of the machine.
    Hope this helps

  • Screen Sharing Problem after Lion Install

    Greetings,
    After installing Lion on my MacBookPro 17", I am now unable to use screen sharing to access my Mac Mini Server running 10.6.8 server.  When I attempt to make the connection, the Screen Sharing application starts, but I never see a desktop of the Mac Mini.  In the system.log, I see entries that include:
    Screen Sharing[2062]: MVS Codec - bad rectangle size - closing connection
    I've tried rebooting both machines and it doesn't make any difference.
    I've only been able to find one mention of a similar message from someone trying to use desktop sharing in iChat, but it didn't include a fix.
    Anyone have any ideas?
    Thanks,
    Dave

    Apple appears to have solved the problem for me.  :-)
    My scenario was a MacBook Pro running Lion attempting to screen share the screen of a Mac Mini Server (My HTPC) running 10.6.8.  Apple pushed some updates to the Mac Mini on 10.6.8, including:
    Remote Desktop Client Update 3.5.1
    Safari 5.1
    Mac OS X 10.6.8 Supplemental Update 1.0
    iTunes 10.4
    After these updates, I can once again screen share with the Mac Mini.  So, my guess would be something in more likely the Remote Desktop Update or less likely in the Mac OS X 10.6.8 Supplemental Update solved the problem. 
    Check your Software Update on the machines that you're trying to connect to and see if that solves your problems too.
    Thank you Apple!

  • Screen Sharing issues MacBook Pro Retina

    Loving my brand spanking new MacBook Pro Retina 15" running Mavericks. Display set to 1900x1200. The only thing it doesn't do, is play full screen YouTube video from my Mac Mini (2011), as soon as I put that in full screen mode on the Mini. Mouse and keyboard no longer respond, the only option is to wait untill it is finished or use the controls on the Mini. My screen sharing is set to all adaptive settings.
    What I have done to do checks:
    remote control MacBook Pro Retina from Mini (same settings for screen sharing, resolution on Mini is 1080p) and play full screen HD YouTube video: no issues, scaling works flawlessly;
    check all network settings on both computer - no issues, both connecting full speed (400mpbs), wireless file exchange proves this;
    reinstalled Mavericks both on the macbook and Mini;
    removed all plists and preferences on both machines;
    saved files to external HD, emptied harddrives, and clean installed Mavericks on both(!) computers
    Installed all updates to december 12th 2013 (including the december screen sharing update).
    All to no avail. So I figured to draw some new variables in the equasion and do some control testing.
    I have done a test from an older MacBook Pro 17" (2010), display set to 1900x1200 as well. No problem at all controlling either computer. Scaling works flawlessly. Dito from an older iMac 21" running Mountain Lion. Like a charm, correctly scaling to meet the screen and network confitions.
    So I figured shrinking the size of the application window on the MacBook to about 1/4 of the surface, and guess what: there she flies. Enlarging the application window on the MacBook Pro has a linear effect on the responsiveness of the screen sharing application, trying to view full screen video the Mini.
    Verified this by controlling the older MacBook Pro 17" (1920x1200) from the MacBook Pro Retina 15". Confirmed that the above problems persist. Shrinking the screen again smoothens things out.
    This quite definite to me, it is the screen sharing application that is not able to handle scaling on the hardware or interact with the software drivers of the Intel Iris Pro/NVidia GeForce GT750M combo. I hope this gets fixed soon!!

    Setting Low Res on the apps didn't seem to help, however (as has been mentioned elsewhere) changing the display settings to non-HDPI does fix it, for GoToMeeting at least.  (Also it let's you appreciate how nice the retina display is, in case you've already gotten used to it!)
    You need an app for that however.  SetResX from http://www.sendspace.com/file/mef6sk works well for me.  To return to nice Retina/HDPI mode you have to go back to Display Preferences (and the "Show in Menu Bar" option for Display Preferences is sadly AWOL in Retina/Lion so you have to navigate through System Preferences.)

  • Drag and drop screen sharing

    I have been able to successfully connect to another iMac on my wirless network with screen sharing. I cannot figure out how take a file on the remote desktop and drag and drop it on to the compuer that I am working on using screen sharing...

    From +*Take Control of Screen Sharing in Leopard:*+
    "GET BACKWARD COMPATIBILITY WITH VNC
    VNC is a widely used remote screen control technology that underlies
    Leopard’s Screen Sharing software, and that Apple previously
    packaged and continues to ship with Apple Remote Desktop (ARD).
    VNC clients are available for nearly every platform, including nearly
    every release of Mac OS X. There’s even a version for a “jailbroken”
    iPhone—one that’s been modified to allow third-party software
    installation.
    VNC service is split into client and server components: a client is a
    viewer; the server handles access to a computer’s screen and manages
    input from the remote user.
    Leopard’s pair: In Leopard, the server is the Screen Sharing
    service in the Sharing preference pane, and the client is the Screen
    Sharing application, which the Finder launches if needed.
    It would be neat if Leopard could be controlled by and access VNC
    clients, right? Well, it can, using either Leopard’s built-in support or
    third-party software. Leopard’s support, built into the Screen Sharing
    service controlled via the Sharing system preference pane, is just fine,
    but if you need more options, you might consider an alternative; see
    the sidebar Picking VNC Software, a few pages ahead, for details."

  • Screen sharing toolbar

    I used the following command to enable the toolbar in the screen sharing application.
    defaults write com.apple.ScreenSharing \
    'NSToolbar Configuration ControlToolbar' -dict-add 'TB Item Identifiers' \
    '(Scale,Control,Share,Curtain,Capture,FullScreen,GetClipboard,SendClipboard,Qual ity)'
    At first a floating toolbar would appear in the upper left-hand corner of the screen sharing environment -- even when I was running in full-screen mode. However, somewhere along the way the toolbar cease to be floating and is permanently attached to the screen sharing window.
    The problem arises when I am using screen sharing in full screen mode. Once I enter that mode, the toolbar becomes completely invisible and the only way I can get access to my local machine is to reboot it.
    Can anyone tell me how to make the toolbar detach itself from the screen sharing window?
    Thanks,
    -sisler

    I re-installed leopard (Archive and install) and put the app on my external, then put it on my internal HD.
    i also reworked the preference file:
    (drag to ~/Library/Preferences)
    http://www.pages.drexel.edu/%7Ecjm67/Sullivan/OS%20X/com.apple.ScreenSharing.pli st
    You can download the following also (the working one)
    Application-Unnzip and Drag to /System/Library/Coreservices and restart a few times-
