Client Server Desktop Sharing Application

I have made a client server Desktop Sharing
application containing a java class for server and
one for client, how can I deploy my java client
bytecode at client's machine without installing JVM
on that machine and not even going to the clients
machine if we are connected in LAN.Well this can be done if the server has access to the clients hard disk you can simply copy the files from the server. But not recamended
I want to start my client program on that machine as
& when the OS starts, so, is there any way to start a
bytecode (or exe ) as a windows service( I dont want
an installer)? Please provide information if I can
get this done by some other service/software and tell
me its name too.Search in google for JavaService it is a simple third party exe that can register java programs as background services
Thanks for your reply (awaited)

Client/server socket based application

hi does anyone have example of client/server socket based application using Spring and Maven
where application do the following
Client sends a request with a path to any file on the server
„h Server reads the file and responds back with the content
„h Client outputs the content to the console
am trying to follow this
http://www2.sys-con.com/itsg/virtualcd/java/archives/0205/dibella/index.html
http://syntx.io/a-client-server-application-using-socket-programming-in-java/
am using java 6

i have attempt code but i wht to do the following
client/server socket based application that will read the content of a file and stream the content of the file to the client. The client must simply output the content of the file to the console using System.out. The client must be able to run in a standalone mode (non-network mode) or in a remote mode.
Additionally the client must be designed in a way that i can print the output to a console but must be interchangeable where if requirements change i can persist the response to file or persist the response to a database.

how can i do below using above code
The program must be able to work in a non-networked mode. In this mode, the server and client must run in the same VM and must perform no networking, must not use loopback networking i.e: no “localhost” or “127.0.0.1”, and must not involve the serialization of any objects when communicating between the client and server components.
The operating mode is selected using the single command line argument that is permitted.
imust use a socket connection and define a protocol. networking must be entirely bypassed in the non-network mode.

Client/server vs. Application Server

Our company has around 30 sites with each one having its own Oracle database server and file server (repository for executables of Forms6i/Reports6i). All the sites have the same applications running, i.e., the same set of programs are replicated to each site. At present we are running the applications in client/server mode (Forms6i/Reports6i runtime is installed on each client machine).
We are also using some third party modules developed in VB/VC++.
Now we are looking for the Centralized Solution, i.e., We want to have a Single Database Server available to all the sites all the sites are already linked with Network Leased lines).
Now we want to know the impact of running centralized file server (located at Corporate Office site) accessible from all the sites (through same client/server mode).
Will this solution work for us or we should move to 3-tier mode? Please suggest us the best feasible solution which can be implemented as early as possible.
What I mean to ask in the question above is: if a good intranet connectivity is available among sites, what would be the better approach, client/server or n-tier?
What actually would we gain by using application server in this context? Does the Data travelling is reduced from Database Server through to the Client Node in 3-tier AS approach? Does this 3-tier approach will reduce the Burden on Leased Lines? Does we gain more network resources available in 3-tier?
What I think is that in client/server mode, the data is travelled from Database Server to Client Machine, but using Application Server, the Data from Database Server will travel upto Application Server and NOT to the Cleint machine (on browser etc.), hence reducing Network Load.
Please clarify as your input makes a valuable role in our decision-making.

Hello,
I'll take a stab at this one...
If you have enough network bandwidth, you should be fine funning in client/server mode. I have worked with clients with this same configuration. In addition to having a centralized DB, we have also centralized the forms on a network drive allowing users to access the same files and removing the need for users having to update their files locally. The biggest problem I see with this configuration, as long as you have enough band width, is that your configuration is not supported as 6i has been desupported.
From my perspective you really don't have any choice but to upgrade your application so that you can be supported. The good news is that for the clients we have worked with upgrades have gone very smoothly. In fact recently we have started to partner with another vendor that has a tool specifically designed to upgrade Oracle Forms and it includes additional features above and beyond what you get from Oracle. This tool has drastically reduced the amount of time to complete upgrades (like going from a 2 year project to just a few weeks).
I hate to answer this question because it is hard to answer without really getting into the details with you. The good news is once you do have a centralized DB and centralized application maintenance will be significantly easier.
One last option you might consider that our company has done is to use Citrix. I've never used it for Oracle Forms, but for other client/server applications it has allowed out clients to web enabled their existing applications without changing them at all and also get a boost in performance. I wouldn't recommend this approach to you because what you have should be short term until you get your forms/reports upgraded.
If you have any specific questions I can try and answer them for you. Good luck and let me know if I can be of any assistance.

Desktop sharing application using c++

I have downloaded the program from here http://www.tightvnc.com version 2.7.10 and compiled successfully using visual studio 2013.
One is the tvn server and other is the viewer.
We connected successfully the server and viewer using my friend’s laptop pair with server and client interaction.
When the application runs all the control of the server computer goes to client. In other words the viewer computer can even hook the server, perform all the actions that a user can do on a local or personal computer and even shutdown the remote
or server computer using application that is even great in positive terms.
But we want to implement/modify the application in such a way that only server can share the screen not the hooking /controlling of entire application by the viewer.
In this regard it is need of removing some .h and .cpp files.
But we do not know what files to remove to achieve the desired goal.
Please tell a way or modify the application in such a way that control never goes to the viewer and always see the screen of the server computer.
Also please tell that when a wrong IP is added through the client/viewer side then the following error comes http://wikisend.com/download/914120/error that we want to find out in the code where
it is and want to modify it in some terms.
Thanks

I assume this is your task to understand how the source works and what you need to do. This forum is a place you can ask if you have problems, but if you want to save the payment for consultant or a C++ professional that I assume you are wrong
here.
I'm pretty sure if you contact the Software owners using the contac link they will offer you consulting for $$$.

Developing a secure desktop sharing application using AIR

Hi all,
I am developing a remote support tool like TeamViewer, using AIR.
So far I managed to implement chat, file sharing etc. However, could not find any API in Adobe AIR to provide Screen Sharing or Remote Support. Can anyone suggest any techniques to achieve the same in Adobe AIR?
Many thanks!

I just came across an article discussing how to use Flash Media Server to create a basic IM application with Adobe AIR. It then mentions audio/video streaming communication - it might be a possible route to take, I haven't really looked in to it at all.
http://www.adobe.com/devnet/flashmediaserver/articles/first_im_app_05.html
Looking at the capabilities of the Flash Media Server itself might shed more light on the issue. I believe it would require the AIR app to be built using Flex though.

Thanks

Hi ADNAN_SHAHID,
Thanks for posting in MSDN forum.
I suggest you contact to TightVNC Developers. You could get support at here:
http://www.tightvnc.com/contact.php .
Maybe you could try to right-click on your DLL project, go to Properties > Linker > Advanced and set “image has safe exception handlers” to No, if you have all the project code.
Read the document about
LNK1281 and
/SAFESEH  , In some case it may be some third party lib files for which we did not have the source code. These lib files are not be compatible with safe exception handlers is because they were created with an older version of the Visual C++
compiler. So you need to contact to TightVNC and rebuild these libs.

Specific Application filter while desktop sharing

I need help for the specific application filter while on desktop sharing. i.e i have to share entire Desktop with current running processe except server application window (UI).http://blogs.msdn.com/b/rds/archive/2007/03/23/writing-a-desktop-sharing-application.aspx
I got the samples for desktop sharing using Windows Desktop Sharing References. In that I need to filter the specific application. But i didn't know How to do that.
By using following things we can try to filter the specific Application. But I want to know, how to call Viewer side share property to fire the OnApplicationUpdate Event on server side.
RDPSRAPI_APP_FLAGS & RDPSRAPI_WND_FLAGS enumeration - How to set the flag for specific application to give high level security process.
IRDPSRAPIApplicationFilter
_IRDPSessionEvents_OnApplicationUpdateEventHandler
Please give me some examples to do this....
Thanks

Hi Narmadha,
Your issue seems to be out of the scope of this forum. We only focus on issue about RDS/VDI deployment, management and operations. For development and API issue it is appropriate to ask in our MSDN Forum:

Latency issue in Desktop Sharing

We are planning to develop a conferencing solution using LCCS. I am trying to evaluate the screen/desktop-sharing application. I am experiencing 5-10 seconds latency during the transfer of the screen data to the other end.
I am using the demo application(ScreenShareSubscriber and ScreenSharePublisher), provided in the SDK.
Some more details:
- Current OS is Windows 7 (32 bit).
- I am behind a proxy.
- I am running the applications in India.
- Using Flex builder 4.6 with Flash player 11.1.
- Using the developer account to test the application.
Questions:
- Can the delay be reduced programatically? If yes, then how?
- The final solution may be used by people distributed across the globe. Is there a possibility that, the latency is affected by your location?
- If the above is true, does Adobe provide cloud services (for commercial applications) that are distributed in different location, to reduce the latency?
- Can proxy server be an issue? We have port 443 open on the proxy server for TSL connections.
- If the above is true, then how can we avoid the issue? The final application may be used in a corporate network and we cannot ask everyone to change their network settings to connect LCCS services.
I have checked some posts on the forum, which say that, the performance is faster on Macs. We are currently not targetting the Mac platform.
Thanks,
Subrat

Hi,
Please double check the following firewall port between two subnets.
Front End Servers-Lync Server Application Sharing service 5065 TCP used for incoming SIP listening requests for application sharing.
Front End Servers-Lync Server Application Sharing service 49152-65535 TCP Media port range used for application sharing.
Clients 1024-65535* TCP Application sharing.
If the issue persists, you can use the Lync server logging tool on FE server to test the process of desktop sharing.
Here is the link of using the Lync logging tool:

Client-server vs timesharing

HI All,
How to describe the Oracle 8i architecture. (e.g., client-server vs timesharing) ?

Neither. client-server is an application environment architecture. TImesharing is an operating system paradigm. Neither apply to oracle's architecture.

Headstart 6i - no client/server support?

Hello,
I have received today list of some new features of Headstart 6i (Beta supposed to be available this week).
In the new features list, here what it is wrote:
<<Because of known issues associated with running Forms 6i in a client-server environment, Headstart 6i will not be certified for client-server deployment. Applications can still be deployed client-server, but Headstart will not attempt to identify and overcome client-server specific issues.>>
Is someone have heard about these "known issues" in client/server?
Thank you
Jean
null

The problems are GUI issues.
The basic problem is this:
Headstart can either be optimized to display in Webforms with the Oracle Look and Feel, or it can be optimized to display in client-server mode. You can't do both at the same time. Since we had to pick one or the other, we chose the Webforms OLAF GUI settings.
You can customize the template package to revert to the client-server GUI settings if you like. This basically involves changes to the visual attributes in the object library, removing the use of the keyword 'automatic' and setting actual colors for foreground color, background color and fill pattern.
There are also problems with displaying the menu and Smartbar. You should remove the icons that are displayed in the menu. If an entire menu group is disabled, the associated icons on the Smartbar disappear instead of greying out (no workaround).
There might also be other GUI issues. As stated, we have not tried to identify or resolve these issues.
Regards,
Lauri

What port number for Desktop Sharing using in Lync Server 2013 and Lync Online

Dear All,
My environment using Lync Server 2013 and Lync online on Office 365. I don't want my user using Desktop Sharing feature. then I need to know what port number for Desktop Sharing using in Lync Server 2013 and Lync Online.
I will deny this port on personal firewall each client.
Thank you for your advise.

Hi,
I'm not sure you'd be able to do this with ports without impacting other application sharing features such as Q&A, Whiteboard, Poll etc - I'm pretty sure they all come under the same umbrella of ClientAppSharing.
Ordinarily you would create or modify your conferencing policy to restrict sharing to single programs only using a cmdlet similar to below;
Set-CsConferencingPolicy -Identity "Global" -EnableAppDesktopSharing SingleApplication
This would disable desktop sharing but enable users to continue sharing other single programs. If you want to remove that functionality too, then replace the 'SingleApplication' parameter with 'None'. Then users won't be able to share any programs either.
This is the correct way to do it as the icons will be greyed out for the users. Doing it your way, they would still be able to click them, and it would throw an error - this will lead to a lot more support calls and people assuming a service is broken.
I hope that helps some.
Kind regards
Ben

External clients desktop sharing fails

After reading through various articles and forum posts I am desperate enough to contribute my first post...
The Problem:
We have successfully implemented a Lync 2010 infrastructure.
Internal to Internal works perfect
Internal to external (or vice versa) works perfect except for desktop sharing (Audio /Video works perfect)
(with external being an internal user in an external network)
I tried to narrow down the problem and found the following issues:
23; reason="Call failed to establish due to a media connectivity failure when one endpoint is internal and the other is remote";CallerMediaDebug="application-sharing:ICEWarn=0x800029,LocalSite=192.168.18.105:5388,LocalMR=xxx.xxx.xxx.xxx:3478(public
IP Adress from AV.xxx.de) ,RemoteSite=192.168.10.73:5378,RemoteMR=xxx.xxx.xxx.xxx:56119
(public IP Adress from AV.xxx.de)
,PortRange=5350:5389,RemoteMRTCPPort=56119,LocalLocation=1,RemoteLocation=2,FederationType=0"
So basically a client connects from behind a NAT device to the external IP of the edge av interface and the internal client tries to connect to the same external ip?
Is that meant to be that way?
Second issue (or same issue but different perspective) same scenario(but network Sniffer on the firewall):
request reaches FW:
50.436292 port2 in Guest IP:35962 -> external AV Edge IP:59676: syn 2844552579
request routed through FW to the internal DMZ IP:
50.436857 Lync-extern out Guest IP:35962 -> 172.16.13.204:59676: syn 2844552579
session gets resetted:
50.437046 Lync-extern in 172.16.13.204:59676 -> Guest IP:35962: rst 0 ack 2844552580
This repeats very often till both clients get a notice about "Network issuses.
On the Edge Server I did an netstat -oa and found Port 59676 to be listening (TCP)
I read so much in the last days that I am totally confused by now and I think the documentation on tech net is faulty somehow.
(at least regarding port 50.000 ->59.999)
Maybe the issue is DNS related (we got split DNS in place)?
Any thoughts helping me out would be appreciated!
Thanks Gunni
Who needs a signature?

Hello Gunni,
please can you tell what is the vendor, model and firmware of your firewall? Are there any kind of "deep inspection" features enabled in the configuration of the firewall.
I am asking, as we have seen similar issues with an RST that seemed to come from the Lync Edge Server, but in fact the connection reset was done by the firewall. In the mentioned case the firewall is a Juniper, model SSG-5.
Two flow related settings activated in the configuration caused the issue, leading exactly to the ms-client-diagnostic: reason="Call failed to establish due to a media connectivity failure when one endpoint is internal and the other is remote"
“flow tcp-seq-check” - (TCP Sequence Check)
“flow tcp-syn-check” - (TCP SYNCRO Check)
Please check if your firewall has some similar or identical settings activated!
A lot of time, we investigated the Edge Server for any issues, - we even replaced it with a new one built from the scratch. Nothing helped, till we start looking closer at the firewall and disabled the settings mentioned above. I remember that we thought
the RST comes from the Lync Edge on the first look in NetworkMonitor and Wireshark. But when we started watching the Juniper reports, and comparing the time-stamps we realized that the connection was closed first by the firewall, not the Lync Server.
If your firewall offers a reporting feature (via webinterface, or SNMP, etc.) I recommend you to take a close look to check if the connection is closed here first.
Thanks and greetings from Berlin,

Lync Application and Desktop Sharing - Restrict remote access/Telnet

I have a customer and they are paranoid about using Lync application/desktop sharing which could potentially enable remote users from getting into their internal IT systems. They are asking if we could restrict application/desktop sharing specifically
for appls with remote access capabilities (e.g. Telnet, etc.)? Anyone could share any information relating to this? Thanks!

We can’t do this with Lync Server natively. Maybe you want to vote idea at

Forms 9i / Report 9i in client server vs Discover Desktop

Hi,
I would like to know how I can deploy an application (forms 9i and reports 9i) without 9iAS Enterprise.
I only want to develop forms and reports for a standalone user. I want to sell my application to many customers, each customer will use the application in standalone mode.
Somebody at Oracle Toronto told me that Discover Desktop is the runtime of oracle forms 9i and oracle reports 9i in client/server mode. Is it right?
I want to run a stand alone application at the lowest cost, without buying the licences of IAS Entreprise (who cost 560$CDN X 10 licences minimum). Oracle said Discover Desktop cost 1400$CDN/user and I can buy only one license.
Is it possible to use Discover Desktop as runtime of forms and reports?
Is there an other possibility to run forms and reports application at a lower cost?
What do you suggest to me?
Thanks.

To run Forms and Reports you must be running 9iAS Enterprise edition. The licence for those products is part of EE only not any other edition of iAS
