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..." :-)

Advanced Java network programming

I have been playing around with the various Server/Client tutorials not only on this site but many others for some time now. Whilst I have learnt a great deal I am now trying to further my knowledge.
The problem is, there does not seem to be a great deal of information on the Web realting to the advanced network programming stuff. Obviously not having a network of my own I am now interested in learning various ideas using the Internet. Obviously not being a prat about it and port scanning other computers or anything like that.
I was hoping someone reading this might have a suggestion about where to go next in my learning curve. Also if anyone could recommend any good sources of info for this type of stuff.
I've currently got three telephone lines in, each line with a seperate Internet account set-up. What I want to do is have them all connected to the web at once and then attempt various things, such as connection, that type of stuff.
Help really appreciated.
Thanks,
kP

Maybe I'm catching the wrong vibe here, but it seems to me that you need to learn a bit about networking in general, before you worry about how it's all done in java. I would suggest a good basic computer networking text book. After you have good understanding of how different networks works, packet structure of the various common protocols, IP, TCP over IP and UDP over IP. I think the java code to implement it all will just fall into place. my AIM SN is SpinozaQ if you would like a book suggestion. I don't have any names going through my head right now.

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.

How to use Advance java function in graphical mapping in XI 2.0?

Hi,
currently I am using a simple java function to make an RFC call to R3 system.
I want to avoid making connection for each lookup. Instead I want to make a single connection for whole message queue and get the corresponding values in some array or container object.
please suggest a solution.
I think this is possible using Advance java function, but I am not able to find any example on using Advance java function at help.sap.com.
thaks in advance.

Hi!!!
I'm not sure if I understood you well.
Do you want to preload some data into your structures in the memory and keep them there so you don't need to make a new connection during processing the whole message or every message?
In my opinion you can cache some data during processing a message, but it's impossible to cache some data between processing messages.
If you write your java mapping or you use graphical mapping (even with user-defined function), then you have a java class. The problem is that XI 2.0 reloads this class during processing every message, so even if you load some data from your data source into your structures in the memory, this data will be lost after reloading your mapping class.

What to do? When on a site with a PDF download I wish to open, the site commences to open in a new Tab but the information does not come through? This happens on all sites. The advanced Java Script is disabled.

When on a site with a PDF download I wish to open, when I click on download the site commences to open in a new Tab but the information does not come through? This happens on all sites. The advanced Java Script is disabled. The new tab will sometimes flash black then go white with nothing else happening or just go white & nothing else?

I had the same problem and also had PDF Download 3.0.02 installed. By removing this addon I can now select a PDF document which then opens up a normal Open With/Save dialogue allowing me to open the file or save it. Hope this helps.

1. what are topics of advance java help in completing this project OR it requires html, dhtml,xml, java script etc.Can I design my project without the "MARKUP AND SCRIPTING LANGUAGES".Web development requires in-depth knowledge of..., well, web development! This is hard work and is going to take lots of time, effort and patience. Don't think you can take shortcuts either, you will really have to commit to get up to speed. But first learn Java and learn it well.
2. what is the best database for java ( ORACLE SQL OR MY SQL OR SQL SERVER)Useless question. You will want to choose a database that matches the requirements for your APPLICATION, it has nothing at all to do with Java.
3.NET BEANS IDE IS GOOD FOR MAKING THE WEBSITE.]Netbeans is only a tool and it will not do the work for you. It might make your life a little easier if you know how to use it properly. The same for Eclipse. Again: it requires knowledge on your part and knowledge you get through study and actually practice.

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.

Can't modify the advanced Java setting

I can't modify the advanced Java setting in Windows Vista if the UAC is on. If I disable the UAC the setting can be modified but when I turn the UAC on again return the old setting. This is a big problem because the jre in IE7 results deactivate and I can't open the Java applet infact the browser show the message:
alt="Your browser understands the <APPLET> tag but isn't running the applet, for some reason." Your browser is completely ignoring the <APPLET> tag!
I have installed the latest version: Java Runtime Environment 6 Update 4
Thanks for the support sorry for the bad English.

Theoritical Doubt regarding Advanced java

Hi, I would like to start learning Advanced Java. From where should i start. As per my knowledge I guess Core Java mainly ends with Applets. Where from should I start for Advanced Java. Upon Core java, is it advisable to learn Advanced Java or else J2EE?
I dont know whether I'm right or wrong to post such a question here.
Any kind of reply is highly appreciable.
Thanks in advance.
Edited by: netbeans2eclipse on Sep 16, 2008 10:07 AM

As per my knowledge I guess Core Java mainly ends with Applets.Before you go off hunting down the elusive "Advanced Java", maybe you should explain
what "ends with Applets" means. Swing? Have you done the following?
1. Written a complete Swing application?
2. Used concurrency in Swing, for example, SwingWorker?
3. Designed your own LayoutManager?
4. Worked with [Java2D |http://java.sun.com/docs/books/tutorial/2d/index.html] ?
5. Used Drag and Drop Data transfer?
6. Worked with some of the more advanced controls, like JTree and JTable?
7. Defined your own model classes?
8. Written code to support undo/redo functionality?
9. Designed your GUI code around an architecture like MVC or MVP ?
The list goes on, but those are the first things that pop into my head.

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?
http://www.amazon.com/exec/obidos/ASIN/1565928709/qid=1006521569/sr=2-1/ref=sr_2_15_1/102-2665779-0587340
btw, have you seen the custom networking trail in the java tutorial?

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.

When turning on Advanced Security Network Encryption tnsping fails

Hi people,
I'm installing Advanced Security Network Encryption in my server (RHEL 3), I've configured my sqlnet.ora as follows:
SQLNET.CRYPTO_CHECKSUM_SERVER = REQUIRED
SQLNET.CRYPTO_CHECKSUM_TYPES_SERVER = MD5
SQLNET.ENCRYPTION_TYPES_SERVER= (RC4_256)
SQLNET.ENCRYPTION_SERVER = REQUIRED
SQLNET.CRYPTO_SEED = "abcdefg"
After that, tnsping do not work anymore, I'm getting TNS-03505 - "Failed to resolve name".
If I remove Adv. Security configuration tnsping become normal.
Do anybody knows what can it be?
Thanks in Advance
André Teixeira

Are you running tnsping from the server to itself? Or from the client? Has Advanced Security been configured on the client?

Advanced java book needed

i need a throrough java book to add to my collection which goes over the most advanced of java programming (reflection, polymorphism etc...) in hopefully one book which has clear examples. if you know of one please give me isbn or title/author id be so grateful. thanks!

So many topics though!
There is a book on Java thread ("Java Threads v2"?)
There are several books on java optimization (like use StringBuffer instead of String)
The Java Lang Spec 2 book.
The Java Virtual Machine 2 book.
The Java Native Inteface 2 book.
I suspect the Sedgewick Algorithms book is good, unless you already have one for another language.
There are some enterprise level books but no titles I can recall right now.
And naturally there are books that apply to advanced java work like some of the design books (like the UML stuff.)
