IPAddress and socket programming

hi frens,
I'm doin a project of storage area networks in which there could be as many servers or storage devices in the network.
My problem is if suppose a particular server on the network is communicatin with other server how will i know the IpAddress/name of the other server which is communicating.
Is there any direct method in java.net as such by which i can get the IpAdd/name of the other server talkin to a particular server.
IF not how do i go bout it?

If you have the server name then DNS look up will work. You provide the server name rather than the IP address and the DNS server on your network will translate it.
If you want to discover the server on your network it is more complicated. Basically you iterate through the IP addresses on your local network and try to connect to each. There might be a discovery protocol in place for this already (you broadcast and they respond) but that depends on the service.
And as a word of warning, if you are working at a company/institution with a security adminstration then you should get authorization from your supervisor in writing to run a discovery interation on the network. Any firewall of any sort will flag such a process as a hack attempt and will notify the security adminstration - which could get you fired/terminated. With the authorization your job/position is protected. Basically if you don't know the head of security on a first name basis then the company/institution is too big for you to take the chance.

Java Swing and Socket Programming

I am making a Messenger like yahoo Messenger using Swing and Socket Programming ,Multithreading .
Is this techology feasible or i should try something else.
I want to display my messenger icon on task bar as it comes when i install and run Yahoo Messenger.
Which class i should use.

I don't really have an answer to what you are asking. But I am developing the same kind of application. I am using RMI for client-server and server-server (i have distributed servers) communication and TCP/IP for client-client. So may be we might be able to help each other out. My email id is [email protected]
Are you opening a new socket for every conversation? I was wondering how to multithread a socket to reuse it for different connections, if it is possible at all.

Network and socket programming in python

i want to learn network and socket programming but i would like to do this in python.Reason behind this is that python is very simple and the only language i know .
anybody can suggest me which book should i pick.
the book should have following specification--
1)not tedious to follow
2)lots of example
3)starts with some networking stuff and then get into codes
thanks in advance with regards.

hmm. well, your requirements are almost contradictory.
Not sure about books, except maybe dusty's.
Most python books cover at least some network programming (unless the book is topic specific).
I use lots of python-twisted at work. I mean ALOT. I wouldn't recommend it to someone looking for non-tedious though! I also like gevent/eventlet (esp. the async socket wrappers).
EDIT: Wow. My post wasn't really helpful at all. Sorry!

Daemon and socket programming

Hi,
I have been given a new project whereby I have to:
1) Write a class with a method that takes as an argument an xml document, communicate s with a SOAP server and return the SOAPs response (in this case a ResponseWrapper object).
2) This then has to be implemented as a Daemon, that listens to a particular socket.
The reason for this being is that it can be uploaded to a server, allowing a pearl program to send the XML to the Daemon, have this contact the SOAP server and then return the SOAPs response back to the pearl program.
I am aware that this sounds unnecessarily complicated but it does have to be implemented this way.
I have written the class and it successfully communicates with the SOAP server and returns a response, but have no idea how to implement it as a Daemon and have had no experience with socket programming.
Could anyone point me to a tutorial or give me some pointers in how to get started?
Thanks,

It was an option to use a Web Service, but I was told
that due to security issues it would take to long to
write all the necessary checks and interceptors
(which I know how to do), so I should implement it
this way (which I don't know how to do); since it is
sitting behind the firewall it would not be
accessible for spoofing.Huh? You realize that tons of very sensitive information is transmitted all over the internet using Web Services right?
I have had no experience
with implementing this type of thing before, What is your level of experience then? This may be over your head. I'm not saying that sockets and daemons are advanced concepts, but I wouldn't throw a beginner into that task.

RESTFUL Web Services vs Socket Programming Performance

Hi guys,
I will have an application which will have a service serving about to 30 million users/day and a mean of 5 requests/user.
It means that there will be about 150 million requests per day. I will have two servers behind a load balancer and my clients will be both Java and C++.
I think to implement RESTFUL Web Services but afraid of performance issues.
Did you have a knowledge about the performances of web service and socket programming in such a high loaded project?
Tnx.

Did you have a knowledge about the performances of web service and socket programming in such a high loaded project?It depends on the CPUs, RAM, disks, and network configurations of those servers.
It depends on how the requests are distributed throughout the day.
It depends on how big the requests are and how big the responses are.

Can i run UDP client and UDP server socket program in the same pc ?

hi all.
when i execute my UDP client socket program and UDP server socket program in the same pc ,
It's will shown the error msg :
"Address already in use: Cannot bind"
but if i run UDP client socket program in the remote pc and UDP server socket program run in local pc , it's will success.
anybody know what's going on ?
any help will be appreciated !

bobby92 wrote:
i have use a specified port for UDP server side , and for client define the server port "DatagramSocket clientSocket= new DatagramSocket(Server_PORT);"Why? The port you provide here is not the target port. It's the local port you listen on. That's only necessary when you want other hosts to connect to you (i.e. when you're acting as a server).
The server should be using that constructor, the client should not be specifying a port.
so when i start the udp server code to listen in local pc , then when i start UDP client code in local pc ,i will get the error "Address already in use: Cannot bind"Because your client tries to bind to the same port that the server already bound to.

How to run a datagram socket client and server program

hi,
I am new to socket programming. I am following the tutorial of sun for socket programming...The link is
http://java.sun.com/docs/books/tutorial/networking/datagrams/clientServer.html
I have understood the concept, but the problem is i cannot run the program. I am using netbeans and i have created a package and stored the files QuoteServer,QuoteServerThread, QuoteClient in this package. How can i make the server program run first and then client program in netbeans
kindly help me
Thankyou

I think you are trying to run both server and client
on one machine!!!
It is impossible, your server is blocking the port to
send packets, so you must run client on another
computer!!!It's not impossible to run a client and server on the same machine just for testing or as a demo. Just have the server listen on one port and the client use a different port.
No need to use 2 seperate computers. I've done it one computer before without a problem.

Socket Programming-Not getting response from server.

Hi,
I am trying to communicate with server using java socket programming, I am getting the response for first two times third time when I am trying to write some thing I am not getting any response from the server,
I am writing to migrate the vb code to Java the vb is using a c++ dll to communicate with the server and we tried accessing the dll from java using JNI then it is working fine, this dll is dependent on windows so we want to avoid the dependency with windows that is why we are going for socket programming, Please help on this.

Hi,
I am writing the data in forms of string
like
Socket sockt = new Socket(ipAddress, portNo);
out= new DataOutputStream(sockt.getOutputStream());
in = new DataInputStream(sockt.getInputStream());
out.writeBytes("Serv");
out.writeBytes("Serv,32");
out.writeBytes("home,serv32,run.prg,sucess");
these are the strings to communicate with server.
I am trying to read the same
StringBuffer buf = new StringBuffer();
          byte b = '\0';
                    try {
               while ((b = in.readByte()) != '\0')
                    char ch = (char) b;
                    buf.append(ch);
          } catch (Exception e) {
               System.out.println(e.getStackTrace());
we are getting the response for the first two strings, but for the third string it is getting stucked for some time and returing some junk values like '???' we are sending the same string using JNI and it is working.

Problem with socket programming(Vista)

I'm not sure if this has something to do with windows vista.
I wrote simple echo client and server programs and the client program contains these lines
String hostname="172.16.54.22"; //My comp's IP
int portNo=6666;
mySocket=new Socket(hostname, portNo);
Now the problem is that the client program is able to communicate with the server only when I run both of them in xp machines or if I run the server in vista and client in xp. The client is not able to connect to the server when both the client and server are running in a vista machine or if the server is running in xp and client in vista.
It'd be nice if any of you could throw some light on this issue.
PS:
It doesn't work even if I turn the firewall off
The programs work well when I give hostname="localhost" or hostname="127.0.0.1"

Thanks for the response Peter.

TCP/IP socket programming in ABAP

Hi,
Is there any method of TCP socket programming in ABAP? For example is there any function module for creating a socket for a IP address and port number. After that, is it possible to send binary/text data to a connected IP/port destination. I need such a solution because I need to send raw data (native commans) to barcode printer on our network which has a static IP address and listens incoming data through a fixed port number specified in its documentation. For a solution, I coded some .NET VB and built a small application that acts as a RFC server program which can be called by SAP according to definitions I made in SM59 (I defined a new TCP connection and it works well sometimes!). In this application, data coming from SAP are transferred to the barcode printer. This is achived by the .NET Socket class library. This solution works well but after a few subsequent call from SAP, connection hangs! SAP cannot call the application anymore, I test the connection in SM59 and it also hangs, so I need to restart the VB application, but this is unacceptable in our project.
As a result, I decided to code the program that will send data to the printer in ABAP as a function module or subroutine pool, so is there any way to create a socket in ABAP and connect to specific IP/port destination? I searched for possible function modules in SE37 and possible classes in SE24 but unfortunately I could not find one. For example, do know any kind of system function in ABAP (native commands executed by CALL statement), that can be used for this purpose?
I would appreciate any help,
Kind regards,
Tolga

Hi,
I doubt that there is a low level API for sockets in ABAP. There is API for HTTP but probably that won't help you. As a workaround you can use external OS commands (transactions SM69 and SM49). For example on Unix you can use netcat to transfer file. Your FM needs to dump data into folder and then call netcat to transfer file.
Cheers

File descriptor leak in socket programming

We have a complex socket programming client package in java using java.nio (Selectors, Selectable channel).
We use the package to connect to a server.
Whenever the server is down, it tries to reconnect to the server again at regular intervals.
In that case, the number of open file descriptors build up with each try. I am able to cofirm this using "pfile <pid>" command.
But, it looks like we are closing the channels, selectors and the sockets properly when it fails to connect to the server.
So we are unable to find the coding that causes the issue.
We run this program in solaris.
Is there a tool to track down the code that leaks the file descriptor.
Thanks.

Don't close the selector. There is a selector leak. Just close the socket channel. As this is a client you should then also call selector.selctNow() to have the close take final effect. Otherwise there is also a socket leak.

Socket Programing in J2ME - Confused with Sun Sample Code

Hai Everybody,
I have confused with sample code provided by Sun Inc , for the demo of socket programming in J2ME. I found the code in the API specification of J2ME. The code look like :-
// Create the server listening socket for port 1234
ServerSocketConnection scn =(ServerSocketConnection) Connector.open("socket://:1234");
where Connector.open() method return an interface Connection which is the base interface of ServerSocketConnection. I have confused with this line , is it is possible to cast base class object to the derived class object?
Plese help me in this regards
Thanks in advance
Sulfikkar

There is nothing to be confused about. The Connector factory creates an implementation of one of the extentions of the Connection interface and returns it.
For a serversocket "socket://<port>" it will return an implementation of the ServerSocketConnection interface. You don't need to know what the implementation looks like. You'll only need to cast the Connection to a ServerSocketConnection .

Java WD and Socket Communication

Hi,
Is it possible to use Java Socket Communication with Java Web Dynpro. Or if not what is the best approach to have a Java Socket program integrated with a Web Dynpro Communication.
Basically, I have an application which provides API for communication via Java Sockets.And this needs to be integrated in our SAP application.
Thanks,
CD

Hi,
You are currently using JCO to "Connect to a Remote System" - JCO will connect to a back-end with the main purpose of "executing BAPI's" in it.
When you move to WebDynpro, you have what SAP calls Adaptive RFC Model - this will create a "Model Entity" in you WD Project that will do the same thing your JCO does.
Assume your JCO now calls "BAPI_GET_FLIGHTS", to return the Flights that are currently available - In your newly create WDP Project, you will manually specify what back-end you wanna use when "Importing" and you will tell also the BAPI name. WDP will generate the class structure that you need in order to execute that function.
JCO is what SAP created to execute BAPI's. JCO can be used by any "Java" like application that needs to connect to the back-end. But when you move to WDP, you don't need to use this anymore - You will use WDP Models.
Youi will still need your JCO Destinations created in the Application Server, so behind the scenes WDP creates a "layer" so you don't need to code the JCO calls manually.
Regards,
Daniel
