Client Server Bluetooth Connection

Our Target is to connect a client (J2ME) running on a cell phone to the server (J2SE) running on the PC via Bluetooth. We are working on our project and this is a bottleneck problem we are facing. We are also beginners and we would like to know steps to set the environment and we need an implementation to connect the mobile and PC.
We previously tried to connect two J2ME programs together via bliuetooth but we failed, we are a bit confused and reached a dead end.

Publishing .fla project including client - server socket connection

Hi,
I have designed with Adobe Flash Professional CS5 a .fla project that integrates a client - server connection.
After publishing it, I have the following issue:
- when running the generated .exe file for Windows, then the connection to the server works perfectly
- but when I am running the published .html file, then nothing is sent to the server.
I have tried to change the Publish Settings.
When setting the Local Playback Security in Flash menu to "Access network only" instead of "Access local files only" then the last packet that was send using the .exe file is resent once and that's all (the html client does not receive the response from the server and the next connection attemps generate data transfer).
I guess I have to change some security settings somewhere but I didn't find which.
Does anybody have a hint ?
Thanks.

Hi again,
I was finally able to solve the issue.
I did not get any error message when using firefox, but using iExplorer provided me this error:
"Local-with-filesystem SWF files are not permitted to use sockets"
Googling did then allow me to find the solution here:
http://www.macromedia.com/support/documentation/en/flashplayer/help/settings_manager04.htm l
The local locations on which I store my html page during the development has to be added to the trusted locations in the global security settings.
Hope it will help some other people.
Best regards

How to set proxy for client-server socket connection?

Hi,
I'm using the code found on the following page to create a client (mobile) to server (pc) connection and send a text message.
http://javafaq.nu/java-example-code-503.html
This works with mobile operators without proxy, but does nothing when the operator uses a proxy. The question is, exactly how to set the proxy and port values for using that code.
Any help is greatly appreciated, thanks,

It's part of the cellular settings, and is usually set up by your 3G provider. You can't choose your own proxy server

Somebody knows how i fix this?

And your server has this FileObject class on its classpath, does it?

Hi,
with your program, you seem to have the full control over your house ;-). Why it shouldn't work over internet as it is? You have TCP open, TCP close...in Internet, you simply have to use other IP-adresses as the local ones. So can you specify your question? Or is it a problem with your LAN-infrastructure, that you have to configure your router to have access from outside?
I don't see why it shouldn't work over Inet...

Socket Client/Server

I have an app using the Client/Server socket connections. Only problem is if the server should drop out and then get restarted, how can I detect the event from the client socket connection. At the moment on fail to send data I attempt to re-connect to the server; but it may actually be a diff error.
Thanks in advance

while (i > 0) {This loop terminates when the server closes the socket. If the server doesn't close the socket it will block in the read() method. So you'll never get to the next part. So either have the server close the socket or arrange your application protocol so you can tell when you've received a complete reply.

Bluetooth client server VIs

Hii all,
I am developing bluetooth application using labview bluetooth vis.
I have my bluetooth enabled PC using bluetooth dongle. Now I want to send some data, say a string Hello from my PC to a Nokia mobile 2700 series. Is it possible?
If Yes , in such case
1) What will be my client and what will be the server? as I intend to use client/server VIs provided in labview example finder . What is the exact difference between client and server in bluetooth domain?
2) Can I run both the VIs on same PC?
3) Simple Client VI uses "Bluetooth Open connection" VI ...so which address do I need to provide there ..is it PC's bluetooth address or Nokia's bluetooth address?
4) Simple Server VI uses "Create Listener" VI who asks for UUID...which UUID needs to be provided..is it PC's or Mobile's bluetooth?
Please do the needful.
Best Regards

In looking at some of the documentation, it appears that the driver required for using Bluetooth with LabVIEW is very specific. You need to have the Microsoft Bluetooth driver - not the driver that comes with the Bluetooth device. Also try lowing your security settings, or removing them.
Here are a few links to try:

Switching WSUS server and Windows 8.1/Server2008/Server2012 clients won't connect, Windows 7/Server2003 is fine

I need to split the load of my WSUS on to another site because the amount of computers is straining the internet connection in the amount of uploads performed.
However I'm having an issue at the second WSUS where only Windows 7 and Server 2003 clients will update...
Windows 8.1 and Server 2008 and Server2012 won't update giving the following error codes: 8024400A and 80072EE2
The WSUS is a Server 2012 with Local Update Publisher 1.1 installed. It works fine locally at the site but not across our WAN.
The clients appear in the WSUS console but fail to check for updates.
I've tried it with the firewall turned off...
Both WSUS servers are using Microsoft SCEP 2012.
Has anyone out there experienced this? Or have any suggestions to fix?
Cheers.

Hi there,
I spoke too soon, I think I got one Windows 8 client to update yesterday by fluke. Now today it won't.
There's not much different between the W7 and W8 systems they both use the same antivirus. Same software but updated on W8.
Here is the windows update.log:

Client Server mode for time ten connection

Hi, I am new to Times Ten and got a question for running TimesTen in Client Server Mode. When it is running in Client/Server mode:
Does the database just run like a regular remote database ?
Is there security for the remote application, such as userid/password ?
Is there any limitation on number of remote connection can concurrently connect to the DB ?
Does it use the JDBC or it has to be the native library ?
Thank you for your help
Henry

Hi,
With regard to your questions regarding TimesTen client/server mode:
1. Does the database just run like a regular remote database ?
I'm not sure exactly what you are getting at here but yes, I would say that it runs like any other c/s database. If you can be more specific in your question then I can give a more precise answer.
2. Is there security for the remote application, such as userid/password ?
If the TimesTen instance to which you are connecting was installed with Access Control enabled then yes, normal userid/password security applies. The client application must provide a valid TimesTen userid and password in order to establish a connection.
3. Is there any limitation on number of remote connection can concurrently connect to the DB ?
Subject to O/S resource limitations, a single instance of TimesTen (i.e. the TT server) supports a maximum of 9,999 concurrent client/server connections. Each individual datastore supports a maximum of 2047 concurrent connections (direct and client/server).
4. Does it use the JDBC or it has to be the native library ?
The TimesTen JDBC driver supports both direct modde and client/server. The TimesTen ODBC driver is provided in both direct mode and client/server versions. The JDBC driver uses the ODBC driver (it is a type 2 JDBC driver) and so the client machine requires a TimesTen client installation to use either ODBC or JDBC to access a remote datastore.

Establish a connection through RF modem's on client & server side & to set up PPP communication for data transfer

hi
can any1 over here help me out in how to establish connection between 2 RF modem's for data transfer , between client & server USing LABVIEW?
I want to establish a connection between 2 PC's through RF modem on client & server side & to set up PPP communication for data transfer.
(I have tried data transfer through RS-232 using TCP/IP whn the 2 PC's are connected over ethernet... which is working.
I also tried connecting loopback cable between 2 PC's COM port & geting data transfer using VIsa configure serial port & other visa functions ... which is working)
can u guide me how to establish connection between 2 RF modem's using LABview?
& how does the data transfer take place between 2 RF modems through RS-232?
is it using TCP/IP?
If you got any links to go abt this issue do send me related links .. or any examples .....
I am currently using Labview version 8.
Waiting in anticipation.. reply ASAP..
thanking you
Regards
Yogan..

Howdy yogan,
Maybe you could clarify a few things for me, and we'll see how we can help ya. TCP/IP protocol occurs through an ethernet connection; RS-232 communication occurs through an RS-232 serial connection, typically through a cable that has a DB9 connector on both ends. Do you mean that the RF modems in question have the option to communicate via RS-232 and/or via TCP/IP ethernet? Specific information like the manufacturer of your RF modems, the model number of your RF modems, and how you connect the modems to the PC would enable us to give you more efficient support.
You can check our Instrument Driver Network (IDNet) to see if a plug-and-play/IVI driver already exists for your RF modem. (You'll need to know its manufacturer and model number.) In the case that you do find an IDNet driver for your modem, you can use this KnowledgeBase article for instructions on how to use the driver.
Another excellent resource to consider is the NI Example Finder. You can access this within LabVIEW by navigating to Help»Find Examples and then searching for serial or TCP/IP examples.

Oracle Client for Windows 2008 R2 server to connect to Oracle database 9iR2

Hi,
We are running Oracle 9.2.0.7 on Sun solaris (64 Bit) 5.10 and trying to install client on new Windows 2008 R2 (64 - bit) server. (Before this 2008 R2 we were using Windows 2003 32 bit and 9iR2 client was working great.) I can't install 9iR2 clinet and I tried installing 10gR1, 10gR2 and 11gR1 but none of them worked. It is only allowing me to install 11gR2. When I installed 11gR2 client I am getting some 'overflow exception on an arithmetic operation' error.
1.) Do I have any choice for client installation or only 11gR2?
2.) Any solution for overflow error?
Thanks,

May I know the reason why ODBC driver is not include in option like Runtime?Oracle software utilizes SQL*Net (not ODBC) to connect to Oracle RDBMS.
ODBC is not required by Oracle client software to connect to Oracle RDBMS.

Urgent!!--- Server Database Connectivity Prob. for clients.

I have Windows NT, and Windows 95 OSs on all my machine.
I have an application designed in Dev-2000. on one computer. (say
that is my server )
Now I want to run my application from other machines (say from
clients) using my server database.
Let me know about configration settings, and another necessory
actions step by step.

if i understand you question, i don't think this is possible, since the Connection interface (and basically all of the related jdbc interfaces) aren't Serializable.. so they can't be sent over the wire to your client(s).
However, you could feasibly write some server side connection pool, and some server side facade which will allow clients to submit queries (either SQL String's or however you want to do it - obviously a more elegant solution involves a series of classes which dynamically create sql based on query criteria), then the server can grab a connection, execute the query, cycle through the results and populate some result object of your creation and send that back over the wire to your client(s).

RMI-Server "checks" when Client closes RMI-Connection

Hi there!
I hope somebody can help me...
I'm developing a client/server application where my client calls a remote method and my server starts working (i.e. 5-7 minutes batch processing).
Is there a way my server "gets informed", when RMI connection is closed (network failure, client closes)? In this situation the server should perform a rollback, delete generated files, etc.
I don't know if there is thrown a exception inside the server method, which I can catch ....
Any suggestion is welcome ..
Best Regards
Anton

Thanks a lot, I will have a look at the tutorial.
Initially my thoughts on this issue were:
-) The Client-RMI call is made in an own Thread (There are several things to do before job processing can start on the remote machine).
-) when the RMI call is processed, the thread gets blocked, so doesn't add load to the machine (hope so).
-) RMI does the "alive-checking", when network connection fails the client can mark the job as failed. The called server should also do some rollback. So I do not have to implements callback-listeners to react on server callbacks
-) But I'm worried about open connections, running out of socket resources and that there is no way to abort a endless running job.
This is my first aproach to solve this problem, I would be very glad about any comment ...

Mac10.x client can't connect to File Server on Windows2008 Failover Cluster

Installation of a cluster was made according to the document "Failover Cluster Step-by-Step Guide: Configuring a Two-Node File Server Failover Cluster " http://technet.microsoft.com/en-us/library/cc731844.aspx.
My Mac OS X 10.5.2 and Mac OS X 10.4.11 clients be able to connect to a non-cluster file server on a Windows 2008 (the File Services role) and also to old file cluster on a Windows 2003.
Why Mac clients can't connect to Windows 2008 Failover Cluster?

Are you running a firewall on the Macs. If yes does it work with out the firewall? If it works with out the firewall that means you will have to create a custom ipf rule which includes the both the physical an virtual IP addresses of your cluster.

Can I tell within my server code that a client vm has connected?

I have some server-side code and would like to modify the code path based on whether a client is connected and debugging or not. For example:
if (!isClientDebugging())
doSomething();
else
doSomethingElse();So what would go in the isClientDebugging() method? I could do something very ugly like attempt to connect to myself and if that failed due to the port not being available I could assume a client is connected. But I have to think there's a better way.

What are you trying to achieve? My client/server system uses simple socket communication. A client can connect to a server and send messages to the server. A client can change the logging state (e.g. "fine for debugging") of the server by just sending a custom command. My server holds references for each client that connected, so the server knows how many (and therefore if at all) clients are connected. If a client disconnects the server will remove it from it's list. If the client crashes the server removes it from its list the next time it pushes a message to all clients because it gets an exception for each client the is not connected anymore.
