Java technology websites

Hi,
Could you please let me know some websites(Other than SUN) which discusses the latest developements of Java technologies .
I am actually looking for websites which give a broad picture of all Java technologies and latest updations. For example, www.javaworld.com .
If you know any other good websites, please let me know.

Is 3G Technology very very very dependent on Java Technology?

I am a green horn in the Telecommunication industry and would actually like to know more about 3G Telecommunication. Currently It seems to me that 3G support Java technology only. Is it true? Also if I am wrongly pls tell me what other languages are supported by 3G? Is there any websites I can look into concerning the 3G technology and how Java is being used in the 3G Technology?
As for the Java Emulator I know that it is actually a simulation of a Java-enabled Phone. But is it reliable? Say if i want to actually program a java game and the test runs successfully on the Java Emulator. So if I upload the program to the server and run it using the real phone, will it works?

Ok what do you mean by 3G? All of the most recent "smart phones" (many of which do not support 3G networks yet) have their operating systems written in C++ as far as I can tell, whether it's Symbian C++ in the case of Nokia, Sony Ericsson... etc, or an M$ Windows CE operating system in the case of Samsung (and probably many other soon). So while they do indeed support java, they run on c++.
You can download the Symbian C++ dev kit for Nokia phones from their website. I've used this a little, and the emulator is pretty good. For C++ you have to compile the phone differently for the emulator and the actual terminal, but I'm sure the java emulator doesn't suffer these problems. Also there are some low level components that the emulator doesn't emulate, but for the most part it's excellent (if a little slow).
What works on the emulator will work on the phone (the reverse isn't always true).

Sales order information to be captured from a java based website

Sales order information entered in java nabled website needs to be retrieved into SAP system and a sales order needs to be created in this system.
And as soon as a sales order is created an bdoc needs to be triggered and sent to the CRM system...
Middleware available for Java SAP interface.
Do i need to call BAPI to retrieve the sales info from middleware ??
How does an idoc trigger as soon as a sales order created i SAP system???
Can any one help me out .Its urgent!!!
Regards ,
Lavanya

Hi,
You have to create a BAPI to read the data from java, the structure has to be the same as in the java system. once the data is read into the SAP system then you need the idoc to carry the data.

What is the roadmap to a new comer in java technology?

Can some one define and explain the roadmap for a new comer who has just formal experience of using computer and keeps only basic knowledge about computers and computer programming? A new comer's mind is boggled with so many unkown terms. Can someone sort them out to make understand simply? What a new comer should know before dipping into the java technology and what must be learnt sequentially?

Take a look at these. Pick the one or ones you like.

I need to know the right tools and java technology

Please help,I need to know the right tools and java technology to support what I need.
I had background programming in Assembly,C++,Visual Basic,SAP/ABAP 4.
All I can say, programming is about logic, now we are very helped building program using objects.
I'm very interest to SAP tech, where all screens, programs, reports are resides on tables, this is the real dynamic!
CUrrently I'm eager to do the same technic with java. I'm new to java....
What I know the J2EE is the core for me to start is it right? I was very interest with the Client-Server Tech. How can I impelemet this with Java?
I'm a bit confuse with so many java solutions. There is Java Applets, Swing, Java AWT, JavaBeans, etc...
I don't know what is the best if I want my Presentation/Client Application will run within browser (not standard html, using like windows gui). What should I do to make business logic objects, how to invoke it within the gui. how to make installation package whenever clients connect to the http server.
if you have a pointer to do it please let me know.... I'm very appreciate all your response...
Best regards,
Lucky Pangemanan

I'd say - don't get carried away with the heavyweight frameworks. Don't use EJB if Hibernate and/or Tomcat will do the job. There's a danger of winding up using a bulldozer to crack a wallnut.
What people mean by "J2EE" varies a fair bit.
Start with Tomcat, which has the virtue of being free. Try some JSPs and servlets.
Use Applets to do client side presentation only if you must; Applets create an installation overhead on end-users, and some of them can't cope, while others may not have the necessary installation permissions on their office machines. They are pretty rarely needed, IMNSHO, most client-side behaviour is better handled with html and JavaScript.

Java technology/framework suggestions required for solution.

Hi,
I'm a C/PRO*C developer (for the past 12 years) and have been asked to do some Java ( which I haven't touched for 13 years).
I would like you input on the 'correct' solution (kind of like an architectural overview) of the technologies I should be looking at.
There are two parts to this.
I need to write a web browser/Application that picks up a file locally on windows PC and reads the contents of the file to populate some url parameters which go to a specific web sevice via HTTPS.
I then need a web service or some kind of servlet (I guess) that on receipt of the request by the client then stores (to a database) the request for auditing and then creates a soap message (using the data receieved) to an external third party( WSDL provided by thirdpparty). Once the thirdparty responds the web server then generates a web page for the client which includes a number of options and details retrieved from the thirdparty are displayed and on the client selecting them the result is sent to the server and the selected option is stored.
Part of this must be that the server must be capable of running as a number of instances. It must be highly secure.
What java technologies/frameworks should be looked out? Is my very rough design fundamentally floored?
Thanks in advance.

So should I use servlets as opposed to JSP? or JCF?Servlets are not opposed to JSP. (JCF? Do you mean JSF?) You can and would use both Servlets and JSP, however, I have grown to believe that JSPs are awful and you should use Velocity instead. From what I've heard of JSF, I'd avoid that too.
Essentially then create a servlet that accepts HTTP request and manipulates a call to the thirdparty, audits data to database, and returns a page back to client which then accepts the option.The server accepts the HTTP request and deals with that lower-level stuff for you, then it invokes your servlet.
The servlet shouldn't call the third party, etc.; it should invoke other code (that you'd write) to do all that. You need a layer of abstraction between your business logic and the web tier. Among other things this will make it much easier to test.
If I were wanting to run this as a in multiple instances then I create a connection pool to the database. But could multiple app instances be able to use one network connection to the ThirdParty?I suppose they could but it seems like more trouble than it's worth and a whole layer of infrastructure that I wouldn't bother with unless (a) you've demonstrated that it's a problem during profiling, and (b) you find that there's some preferably open-source library that handles this for you.

What platform/java technology should I use? Please Help

Hi, I am a uni student and have a final year java project to do.
The project must include:
1. a server side application that must run at specific times during the day (3 x a day) and store information to a database (MySQL).
2. a client side desktop application that will connect to the database and retrieve the information.
I have no problems writing the client side application. However, I am totally lost when it comes to knowing what server I need to have running the server side application and what type of java technology the server side application should use i.e EJB, entity beans etc??? How would the appliaction run at certain times, would I use a timer class? What would be the best way?
I would appreciate any advice you can give. Many Thanks.

Hi,
1. ok if I develop my application as a "normal" java
application does this mean that it needs to run on an
aplication server?No, it doesn't.
2. is developing the app as a normal java app
considered a good way of implementing such a system,
or would it be better to use enterprise bean
approach?That depends on your professor. Given nothing other than the requirements you stated, there is no need for an application server. You can just have a command-line app that runs forever to do these server things. However, if your professor wants you to learn about J2EE servers, then it's a different story. So ask your instructor.

What's your strategy for learning Java technologies?

Or, in other words, how do YOU acquire knowledge that is necessary for implementing Java technologies?
After having spent one-and-a-half years developing an enterprise app, I've gained lots of knowledge about Java and some surface knowledge about its related technologies (JBoss, Hibernate, Ant, XDoclet, NetBeans and probably some others I can't think of at the moment).
I'm now realizing that -- although the standalone prototype version of my program is growing mature -- I've still got lots to learn for refactoring it to a web platform. For example, I 've done small test projects using Servlets, but haven't done any work with JSP (or HTML for that matter) yet.
Now, I'm sure I can learn JSP etc., but the questions I ask myself are: how long will it take?
It's a rhetorical question of course (I don't expect an answer from you, the reader) However, it's an important issue because the months or years I spend fumbling around learning these new technologies, are time I could otherwise spend on the business logic and functionality of my program.
So, how do you guys acquire knowledge of technologies? Official training perhaps? Or do you simply experiment until it works? Or do you rely on your company's knowledge base (e.g. someone in your company knows how it works)? Or do you get prototypes built from someone who already knows how it works?
I�m really curious about this and would appreciate your thoughts.
Thanks in advance,
P

Well, it seems like most of you simply read the
various texts and try the vendors' examples. I'm
surprised that no one mentioned ever having bought a
prototype application from the onset. "bought"? What's that mean? You don't buy prototypes. You download evaluation versions, maybe.
I try to find sample code and tweak it to see the effects. Otherwise, I start writing small sample code an build on that.
I consider myself a reasonably competent core Java
programmer, but I had serious difficulty configuring
and merging its related technologies. There were so
many disjointed pieces of instructional information
that the additional research time really hurt our
budget severely. Not an uncommon thing, I'm sure. There's a lot of stuff. But don't bother learning all of it. Not in detail, at least. It's a good idea to familiarize yourself with the names of packages/libraries and what they do. But only really learn what you need to learn for what you need to do. The next project you will probably need other things, so you learn them then.
bsampieri,
I've setup Tomcat and tried the examples--in fact, I
normally follow tutorials for all products I hope to
use. Problem is, the examples and tutorials never
address my specific needs. So, I usually inch toward
my goal by spending weeks or months in forums to
continue where the tutorials leave off. Anything complex is going to not be there.... the trick is to identify pieces that you can pull out to build more complex apps. And the fact that JSP/servlets have the issue of being compounded by all the HTML/CSS/JS and HTTP protocol ... I don't want to say limitiations, exactly... Well, it just makes things more complex and harder to know what you need.
Perhaps you guys are much faster and smarter than
I...or you have a much bigger budget :)Probably not... on either account.

Brief Idea of Java Technology !

Hi all,
I m a Form/Report Developer in 11g and want to use JAVA in my 11g Forms/Reports application.
But I have a little knowledge of Java, and Java has also so many technologies, and confuse to start the technology.
So, want some brief idea of all JAVA technologies like JRE,JDK,Java Beans, JSF, Jdeveloper, ADF, Core Java, Advance Java, Spring, Rail etc.,
so that I could start/use JAVA technology in my 11g Forms/Report application.
Please suggest me best for my 11g Forms/Report application !
Thanks/Regards.

The {forum:id=82} forum is a better place to ask about how to use Java with Forms, but then you'd know that already, since you asked the same question over there.

Is it Possible in JSF? Can anyone recommend any java Technology for this?

I am doing Post Graduate Degree in Computer Science. This is my final semester and doing project work.
Any body having idea about my requirment, help and guide to me
My description and questions are as follows:
Current Approach:
PHP has been used to achieve the flexibility of creating custom images on-the-fly. Using this approach we were able to create a web-interface similar to the application client, where we could display links and get the exact look and feel of the application client.
Drawback:
This approach forces us to use two different technologies Java and PHP, since our system uses 'Java' accessing all the API's from PHP becomes a problem. while PHP provides a way to invoke any java method. It comes with a draw back, the method calls are little slow. This delay's are loading of web-page.
Requirment:
1. Creating custom images on various locations of the screen
2. The Exact look and feel of the application map should be achieved
3. Place elements and links correctly as in application-client reflect any changes
4. Generation events on the Links and Elements
5. Setting Backgroud images for different maps
Questions:
1. is it possible in JavaServer Faces (BETA)?
2. If it is possible is JavaServer Faces(BETA) How to create custom images and create interfaces among them?
3.Can anyone recommend any java Technology for doing this?
Anybody having idea, help and guide me for doing my project

hi,
I think you can use JSF

Look for general blog on Java technologies

Hello,
I am greatly interesting in Java and look for active blog on Java technologies. I found 1000 of blogs posted in this forum but many are very specific or not active anymore. Could you please advise me good java blog with regular posting and interesting articles on different part of Java?
thanks
sebastien

To write JNI code for integrating of an activeX is not a simple task. You will face with a number of problems related to COM:
- when and where to call CoInitialize and CoUninitialize,
- how to clean up COM references on Java Application exit,
- when to do Thread Marshal and when it is not needed for COM interfaces;
- how to Marshal and Unmarshal COM parameters in Java methods calls to COM Interface methods, etc.
The best decision is to use some Java-COM Bridge.
My company has developed tools like
- Java-COM Bridge
- Object-Oriented JNI SDKs for C++ and .NET (v1.1,v.2.0) languages (do not mix with JNI wrapper generators). These are an object-oriented maps of the regular JNI SDK,
- Add-Ins for MS Visual Studio v.6.0 and v.7.1 that generate Java wrappers in C++, C#, J#, MCpp, VB for Object-Oriented JNI SDK.
So we know problems you have.

Migration From D2K to Java Technology

Hi Everyone,
I am using Oracle D2K 6i Version from the last four year for transaction form for my company.Now because of low bandwidth and for multiple centers it is needed to go online. My Company want to switch to Java Technology with oracle database. Please tell me is it possible if i am going to create big transaction form(s) having 5th level of master/detail relationship. if yes so for which technology of java like (JSP,struts, hibernate) or something else i need to look forward.
Your Suggestions are most welcomed.

This forum is only handling foreign database to oracle migrations. You might better post your request in the Java or Developer forum
