Socket related help
i have a problem while reading data from sockets regardless whether its sever socket or client socket is there any machnisum or indication by using which i m able to know that data is just recieve on the client side or server side during continous client server communication.i m developing a client server 3 tier application wainting for +ve response from anyone who can help?
watching for ur kind assitance

It sounds like what you want is full duplex communication. To do this you need 2 threads for every socket if using the stream based sockets, one thread for read and one for write. Your other choice is to use NIO. You also must be careful to ensure that the socket writes are followed by a flush() when they must be forwarded or the data will sit in buffers on the sending side until the buffers fill up or the socket is closed. I posted an full duplex, multi socket echo server that uses multiple threads on http://forum.java.sun.com/thread.jsp?forum=11&thread=526980, reply 3.

AppleCare or Customer Relations help requested
I have been a Apple customer for years. Started with a II+ followed by Mac+, MacII, iMacG3, MacMini G4, then another Mini G4, and now a MacBook Pro. Macs have worked well for me, and in return, I have bought several Apple products.
Unfortunatley, the string of luck with my Macs has come to an end.
I got on the waiting list to upgrade to a MacBook Pro as soon as they came out. By the second week they were shipping, the store called me and told me they had my MacBook. Very good service.
I get it home and first find that even though its a notebook, its NOT a laptop. Even Apple won't call it a laptop, they call it a portable. You know why? Thats because they run so darn hot, if you sit it in your lap while running, it will literlly burn your legs, and I have to put a pillow in between it and my legs.
After 3 months of using my new MacBook Pro, it started rebooting randomly, had lousy performance, and was overheating. I took it to the apple store for repair. They replaced the motherboard, heat riser, and a couple of other items and return it to me. The random reboots are gone, but it still runs mighty hot.
Take it home. Use it for a couple more months. Now it starts having other problems. Like it just randomly powers off. No warning. No battary low prompts. Just boom, and it shut off, even with a battary that has a 90% charge.
It also locks up frequently. Not completely locked up, just fits of no response. For 15 or 30 seconds, the computer just won't respond. No mouse clicks. No keyboard entry. Won't even respond to trackpack movements.
Then, after using it for a couple of hours, it gets dog slow. The same apps that ran okay right after you fired it up just start running slower and slower. It's not running out of memory, as I have 1.5GB of ram in it. For some reason, it just gets slower with use, even if you close all apps, and restart just one app. It's not whats running at all, it's just how long you use the computer after startup that effects it's performance. And no, I don't run PPC apps. I only run universal apps.
I post this information on a popular mac forum, and someone tells me that the fan is defective, the computer is overheating, and therefore, the processors are slowing down to protect themselves from generating more heat.
I know intel processor are designed to do this through their TM1 and TM2 thermal monitoring, so this makes complete sense.
I go to apple store, they do some tests, tell me that I have a bad battery. They replace it under warranty and call it fixed, and tell me to pick it up.
This may explain the random shutdowns, but it doesn't explain the constant performance problems. I told them about the overheating, and again, they failed to listen, although they did run 24 hours of testing. I guess they get so many hot MacBooks, that they don't really know when one really runs hotter than it is supposed to
I guess I'm just frustrated. I'm going to pick it up again tomorrow, but with only a battery replacement, I really don't think they have addressed the other issues, and I know I will be bringing it back in again.
As a devoted Apple customer, I am starting to loose faith. Can someone in AppleCare or cutomer relations help?Don't take this wrong. But I'm not going to spend $60 more dollars on this computer to turn it from a portable into a laptop.
They sell these things to the un-suspecting public (at least in the beginning) as laptops. If the thing is designed wrong and gets too hot to put in a lap, then don't call it a laptop - which they don't now anymore.
I may sound stubborn here but let me make my point. Everyone wants me to spend money to cover apples less than stellar product. Buy a iLap to make up for the heating problem. Buy apple care to insure that my lemon keeps on running after the warranty 1 year warranty. Someone else has suggested that I try to debug the problem with this computer and take pride in solving it myself - and to some point, I agree with him.
But the thing that makes me mad is that I paid a premium for this computer. I was an early adopter that bought this computer in week 2. I bought this computer to move over to the intel core mac's for the extra performance they offer, and because I have had such good experiences with apple and Macs before. I'm just not going to invest more of my time in this thing. It's time apple step up and take responsiblity. -

Greetings,
I have an LV 8.6 HMI that performs Data Socket reads
from Network Shared Variables. I am finding that it works well until I
try to shut down and close all the DS references. I can usually get
away with this
once, but if I try to restart the application I often
will not be able to reopen the DS reference and it will always crash
when I try to shutdown again. I have narrowed it down to just DS opens
and closes
and the problem persists. Attached is the error message
that pops up when LV crashes, not much to go on but any ideas would be
greatly appreciated.

DS Related Error.PNG 10 KBHello,
Which version of Windows are using? There are some cases in the past with NT that relate to this error because windows was updated. A Microsoft KB explains that here.
This also may be an issue with the Shared Variable Engine having a conflict with the firewall or antivirus software. You may need to go through this document to configure your windows firewall if you already have not.

Sending object over socket - please help (urgent)
I have written a server/client application where server sends object to client.
But on the client I've received the first message "@Line 1: Get ready!!!" TWICE but NEVER the second message "@Line 2: Please input Start".
Please help me! Its urgent! I appreciate my much in advance.

Hi,
I have to open a socket connection to a server using the providers documentation. Can somebody help translate it in Java for me. This is what the documentaion has:
fd=socket(AF_INET,SOCK_STREAM,TCP_PROTO)
myaddr=(socket structure){AF_INET,wsport,myIPAddr)
bind(fd,myaddr)
apiaddr=(socketaddr structure){AF_INET,SERVER_PORT,serverIPaddr)
connect(fd,apiaddr)
AF_INET=2, SOCK_STREAM=2,TCP_PROTO=6
wsport= a unique client port
myIPAddr= client IPAddr
SERVER_PORT,serverIPaddr- known
fd- definition of socket connection
Thanks a lot,
SanjayOkay guys, document, document, document! This is what happens when you don't.
Key: bold items are the object names, they explain what I believe they refer to and how to work with them.
fd=socket(AF_INET,SOCK_STREAM,TCP_PROTO)
fd this is a java.net.Socket constructed by using AF_INET this appears to be the java.net.InetAddress for the server (or possibly the client, or a locally binding IP). SOCK_STEAM appears to be either a java.io.InputStream or a java.io.OutputStream from which to read or write from/to the socket. The last thing is TCP_PROTO which I'm guessing was spelled incorrectly and was meant to be TCP_PORT, this is a int that is the port number (0 to 65000) for the connection to be bound to (locally, is server else remotely if client).
myaddr=(socket structure){AF_INET,wsport,myIPAddr)
myaddr again a java.net.InetAddress cast into the appropreiate IP type such as IPv4, IPv6.
bind(fd,myaddr)
bind a method, local to the class since there is no object reference included.
conatins the objects fd and myaddr this most likely creates the connection.
apiaddr=(socketaddr
structure){AF_INET,SERVER_PORT,serverIPaddr)
apiaddr some IP address, based on AF_INET, SERVER_PORT, serverIPaddr.
AF_INET see above.
SERVER_PORT the port number for the server
serverIPaddr the IP address for the server
connect(fd,apiaddr)
connect a local method of the class, this seems to connect to the server while bind connects to the client. fd is used again, and also the new apiaddr.
AF_INET=2, SOCK_STREAM=2,TCP_PROTO=6
AF_INET see above: the line sets the value to 2, so it must be of a numerical type.
SOCK_STREAM this also seems to be a numerical type, this would invalidate my first note.
TCP_PROTO value of a port number (not sure client or server-side port number), numerical type.
wsport= a unique client port
wsport a numerical type, TCP port number, refers to the client-side port number used for the connection.
myIPAddr= client IPAddr
myIPAddr "mirror" of the IPAddr value of client
SERVER_PORT,serverIPaddr- known
SERVER_PORT or serverIPaddr is throwning some sort of exception.
fd- definition of socket connection
fd some type of descriptor, states that it is of the socket connection, possibly a java.net.SocketOptions object.
Now that I did your work for you, I demand payment. -
BufferedImage over socket need help
I have written a program that gets frames from my webcam and can save it to my hdd as jpg files, which works fine. I would now like to send the bufferedimages from my server to connected clients instead of saving them to my hdd. I've searched for help on the forums but can't find anything that works. If you have any ideas or code snipets on how to send the bufferedimages and receive them it would be appreciated. Thanks.
Just send them as regular files.If you can write your images to a temp file, send them as such:
in = new BufferedInputStream( new FileInputStream(file));
out = new BufferedOutputStream( socket.getOutputStream());
And receive it on the server side as such:
BufferedInputStream in = new BufferedInputStream( clientSocket.getInputStream() );
BufferedOutputStream out = new BufferedOutputStream( new FileOutputStream(file) );
//write it to the client's hdd
Once you send your file out, just delete your temp file.
I hope this will help. -
I am trying to create a peer-to-peer messager using Sockets. I have a Listener class that listens for connections and accepts them and creates a new socket for each connection and also calls a ChatHandler which is passed the new socket. Exept the StartConv class which connects to the listener class initially never finds out about the new Socket and thinks it is still connected to the listener port :(( Here is some of the code i am trying to use for each of the classes:-
Listener

}It says at the top :) think i posted too much code but that way everyone knows exactly what is happening. Cant get the StartConv class to commmunicate with the ChatHandler basically

Hi Folks,
I need an urgent help on IDOC issue for COR3 Transaction.
We have one legacy system from where data is coming for a particular Process Order. Now in Process Order display transaction COR3 when we go to Good Receipt Tab, and double click on batch, it displays the batch characteristics. Now Batch Detail's classification tab there are characteritics values. These characteristic values are suppose to store multiple values. We have changed in configuration.
Now when I execute the IDOC it stores only current value. It is kind of that it overwrites the previous value and keeps the new value in it's place and i want to retain all the values from the very beginning to the end. Please help me with the same.
Siddarth.Try a hard reset.Disconnect all external devices first.

Oracle Business Events related help needed
Hello All,
Good Morning , wanted some help regards Oracle Business events be used for sending notifications.
We are having a situation wherein we need to send notifications to the sales team whenever there are changes to the order line status..lets say the order line moves from Booked status to Awaiting Shipping status and further to Picked or Shipped status, we need to notify the sales team about this.
If we are going to use Business Events concept for this we wanted to check on the below points -
1.At the order line level what all seeded business events have been defined ( means if we could get the complete listing ) and whether any of these gets triggered when the order line status changes...we are on Oracle Release 12.0.6 version
2.Also is there a way to know what all parameters are being passed for a given seeded event, so that we know which parameters we could retrieve within the subscription using wf_event_t.getvalueforparameter function.
3.Regards setting up Subscriptions for this order line seeded business event : means we could see an option which says : "Send a Notification" when we are defining a Cstom Sbscription ( Now here it asks to give the Message Type ( This would be workflow item type where the message is defined in workflow ) and Message Name ) ..
Now if in this NOTIFICATION MESSAGE we need to show details like order number , sales rep , order line status etc ( then where do we set these details in the Event and also how do we pass these details from subscription so that it shows in the notification )
Means where do we setup and define values for the notification message attributes and how do we pass these values from event to the subscription and finally to the notification..How do we achieve this because some of the message attributes for the notification are Document Type while some are text/number types.. These would be required to show in the notif message...
4. Also once we send the notification lets say succesfully to person or a role using a subscription , how do we capture the response ...
Could someone please help us with this as we are stuck with this at the moment.
many thanksHi,
please reply the above questions.it would be a great help for me.
Thanks

Gmail related help needed ASAP
Hi guys, this is my first post here. The iPhone has been great so far but I'm in a bit of a bind with some Email features and wanted to see if any of you 1337 pros can help me out.
I have road runner email and it's all routed to my gmail account. I setup my gmail to go through my iPhone now. The problem is my iPhone wants to download all 3678 messages in my gmail account! Even the ones I already looked at. It also sends all my replies back to me.
How can I setup my gmail and iPhone so that it only downloads new messages from today forward? Also how can I set it up so that the emails stay NEW on GMail even tho I may read them on my iPhone?
Thanks for any help in advance I appreciate it.
Regards,
iPhone Gmail setup retard. =PI can probably help with the more pressing problem, the 1000+ emails. The fix, I think, is on the Gmail side. You need to go into settings and turn off POP access to your Gmail and save the changes. Then, you can re-activate POP but set it to only retrieve messages from now going forward. This is what I did when I configured my phone and it worked.
As to keeping the messages "new" even after reading them on your phone, so long as you are using POP to get the Gmail, this should happen as a matter of course, at least it does for me but the forwarding of stuff from your cable account might have some impact upon that, I don't know. -
How can I dynamically search SMTP Server on a particular Network?
you can test whether a machine is an smtp server by opening a socket connection to its SMTP port(25) and reading the response
Socket soc = new Socket("the_machine_name",25);
BufferedReader br = new BufferedReader(new InputStreamReader(soc.getInputStream()));
String response = br.readLine();
if(response.startsWith("220"))
System.out.println("Its a Mail Server");
however, if u need to search for an SMTP server on your network, u have to know the name(or IP) of all machines on the network (LAN).
does anyone know how to find out the IP of all machines on your network ?
