Java network

hi
I want to know more about java network programming.
Please tell me where can i get it.

It's not avaiable in amazon, yes?

btw, have you seen the custom networking trail in the java tutorial?

Newbie question on JAVA networking

Hi,
I'm newbie on JAVA networking. Can anyone guide me to do a task to :
read the TCP/IP packets which are sent from a specific host to another host? I need to capture the packets and analyse the contents.
thanks in advance,
jackling

Well I've search google for a low level TCP api, but I came up with absolutely no results. So I guess the only way would be to write your own native API (using C/C++) and call this through the Java Native Interface.

Urgent Help in Java Networking

Dear Sir,
I've written an encryption algorithm.My problem is i 've to encrypt

computer.I have written both encryption and decryption algorithms
but i dont know Java networking API.Could you give me detailed step by
step networking code with documentation which connects both encryption and decryption algorithms at different computers.GUI Support in networking api is appreciated .Please sen the reply to [email protected]

Have you looked at JSSE (Java Secure Socket Extensions)?
Using SSL is perhaps the best solution to your problem.
You can find a lot of info in:
Java Security - 2nd Ed, by Scott Oaks and and in
Java Networking (or something like) 2nd Ed, by E. R. Harold.

Java networking library with RMI-like functionality?

Is anyone aware of a Java networking library, that provides RMI like functionality and TCP/IP with an intuitive API and minimal coding required? I'm working on a prototype, but I'm having difficulty getting Java's RMI functionality working through Netbeans, so while I'm prototyping I'm looking for alternatives so I can code more and frustrate less!
Thanks

Thanks ejp.
I guess I'll re-phrase the original question. Is there a small open-source Java networking library that doesn't include RMI, but gives a simple API for TCP/IP connections (higher level than sockets) and includes file transfer? I don't know if I need things like FTP/HTTP/POP/SMTP support etc for now.
ThanksI gotta be honest with you here. I think you need to stop coding for now and get your requirements in hand with a better grasp on how network programming works.
Not being insulting here but your questions show your current knowledge level on the subject to be not really sufficient for success with whatever it is you want to do.
There is the networking tutorial available here http://java.sun.com/docs/books/tutorial/networking/index.html but it might do you well to tell us exactly what you are trying to do. Are you trying to build an FTP client? Are you trying to build a whole client/server program of some sort?
Because everything now is very vague. You seem to be looking for protocols or API's between TCP and things like FTP for example and none exist because these sit directly on top of TCP. So you either deal directly with the Sockets or you deal with some library that deals with the protocol in question. There isn't an "in-between" layer here.

Java Networking Books

I am doing a project in Java Networking,kindly suggest me a good,solid
book on Java Networking.

I think the combination of the worker thread from Example 12.2 and its driver Example 12.3 do not distribute connections evenly among threads. Or, am I wrong?

Java Networking (AesSoft Ocean2002)

Hi my name is Donald. I am working on a java based program called Ocean2002. This software will be an entertainment software with games Instant Messanger and more.. I am a beginner with java networking so i need some help with the instent messanger. If anybody has any ideas how can i start an instant messanger based on java please help.
Thank You!!!

There are two options, Peer to Perr and client server.
With a P2P instant messenger, each user will need to know the IP address of another user to contact them. That isn't exactly pretty.
The client/server approach can be done in 2 ways. The first method is that when a user signs in, the messenger sends the user's IP address up to a server and also asks the server if anyone on the users 'buddy list' is signed in. When a user wants to IM another user, it requests the IP address off of the server and then connects over a predefined port.
The drawback of this configuration is that firewalls will stop the messenger from wroking.
The second client/server approach will have the server manage not only a mapping of users to IP's but will actually handle routing the messages. This is basically a Chat room implementation but with a thick client. Each client messenger will periodically pool the server for new messages. Once a new message arives, it will probably be most effecient if the client and the server will hold onto a constant connection until a certain time limit has expired (the conversation has 'ended').
Basically, the server (server meaning anyone listening for a connection such as someone listening for the phone to ring) uses this:
ServerSocket ss = new ServerSocket(1234); //Port number
Socket s = ss.accept(); // actual communcations happen over the Socket s.The client (the one making the phone call) will look like this:
Socket s = new Socket(InetAddress.getByName("12.34.56.78"),1234); //Connect to the other box
//All communication will happen over the Socket sAll of the above classes are in java.net. Look at the Socket class to see how to get your input and output streams.

Java networking Documentation?

can some1 provide me a link or a site that has documentation about java networking packages and classes? i am subscribed to a virtual library but the latest java networking book is from 2000(too old) and i have found individual documentation about corba,rmi or sockets for example, but not a good source of information that englobes and link java networking topics, all is about web services,j2ee,etc.
i am lost here, =(

Advanced Java Networking Tutorials

Hi,
Can you please give me some links where I can find some Advanced Java Networking Tutorails. The tutors I find in Sun site are not so advanced.
Thanks
Joe

What kind of advanced networking? RMI, Corba, SOAP, ...? Google for tutorials. Plain sockets? After you know the Java socket API you'll need to get into the fine details of TCP, UDP and IP which are mostly language independent.
There are also books; one is "Fundamental Networking in Java", the author of which regularly hangs in the Java socket programming forum. If you get his book you'll always have someone who can't possibly refuse to help you: "hey ejp, I read your book and I have this problem..." :-)

Multiplayer Java Game with java networking ???

Hi everybody. I responsed a new university finising project. I will create a new game that multiplayer on a server. I am in a simple level on java. I have no java networking or no jdbc info. I belive I can success but I have no idea about which map i should follow. I will wait for your suggestions.
(Or can I find a muliplayer game sample with java networking?)

Maybe you could use RMI if you haven't got latency problems (that u will encounter certainly if you intend to use it with 56k modem).
It's quite flexible and in java 5 also more usable.
