Latest java technology....

Hi all,
i m want to know what is the latest requirement of industry from a java developer and what is the new java technology the developer should go for that..
thanks & regards,
john

Developers should be able to google.
Everything else can be learned from there.
But seriously: look around at some news pages and job portals and just look around. You'll get a pretty good view over what's important.
Some of the J2EE basics are almost always usefull: JDBC, Servlets, JSP. Others are required sometimes: EJB.
Tomcat Know-How is a definite advantage, as is Spring and Hibernate.
Basically I'd say that for most jobs server-side Java is the most important part.

Latest Java XML technology

Hi, can anyone tell me what's the latest Java XML technology? Is there anything similar to .NET DataSet? I know SDO has a feature "changeSummary" to make the update of XML data easy. But it looks SDO is not popular now (correct me if I am wrong). Is JAXB the only popular framework for Java XML? Is it as powerful as .NET DataSet? Thanks

Dude, this is a Java forum. Do you really expect people to know .NET stuff?
JAXB is an API, not a framework. Its not popular, its part of the JEE spec which basically makes it a given to use it. You can use it to do XML binding stuff; nothing more, nothing less. It is used by several other APIs to do the XML binding stuff, like JAX-WS. When used properly you can quite effectively bind XML documents to an Object hierarchy and the other way around.
A piece of advice: if you want to do Java stuff, forget .NET exists. If you can't do that, at least stop doing that "I do it like this in .NET, how I do it in Java?" way of thinking. You have a problem which needs to be solved, go find something that works.

Latest Java for OSX -- Up-To-Date? Where's new?

I sure could use answers from you Gurus out there, or pointers to where I can get the straight poop. TIA.
I use a non-Apple produced Chat application (gabbly) that I believe is written in Java. One day last month, this app suddenly lost its graphics. Some buttons became invisible, though their mouseovers were still visible, and if I wait till the mouseover shows up to show me I'm still on the invisible button, "it" will work. Other graphics work wrong, also.
I use adblock in FF, but no joy if I turn it off.
I cleared all FF cookies with "gabbly" in their names; no joy.
In Safari, the app kinda works better -- graphics are there, but some buttons work wrong.
Curiously, another Mac on the same LAN shows the app working fine under FireFox 1. (that rev UTD, OSX UTD) So it's probably some machine-dependent thingie...

The Java test at http://www.java.com/en/download/help/testvm.xml says that I'm "using an older version of Java technology" and that a new one, 1.5.0_07 from Apple, is available.
HOWEVER! Under the Apple Operating System of that same display, is gives my current JRE version is 1.3.1 for OSX 10.2.7.
So, how can it be possible that my 1.5.0_07 is an "older version" of Java, when the lower segment of the same URL's display offers me 1.3.1 ?
And should I downgrade from 1.5.0_07 to 1.3.1 ? To me, it looks like Apple's version of Java is more advanced than the version now on offer from java.com...
Or should I re-install the latest Java from Apple, which another string has pointed at, at http://www.apple.com/support/downloads/java2se50release1.html ? This is all so confusing...

I agree, the Java version numbering could have been better implemented. Supposedly there is something called Java 2, which has been out for awhile that's included in it. Some people here might have a better answer for that:
http://discussions.apple.com/forum.jspa?forumID=727
I don't understand why the numbering system isn't clearer.
Apple does have this page on Java which may be of some help:
http://www.apple.com/macosx/features/java/
And Wikipedia has this page:
http://en.wikipedia.org/wiki/Java%28programminglanguage%29
As you can see J2SE is actually numbered 1.1.4 through 1.6.

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?

Java 6 you can't as Apple maintains it, and Java 7 you could if you uninstall it and Oracle provides the earlier version which they likely won't his last update fixed 37 remote exploits.
Java broken some software here and there, all you'll have to do is wait for a update from the other parties.

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.

Latest Java release (1.6.0_25) crashes systematically on Firefox

The online software developed by my company uses multiple Java applets on the page. When we tested the latest Java update (1.6.0_25) last week, we realized that Java would unexpectedly stop when used with Firefox.
I managed to create a test page to reproduce this issue. In the page, I used applets available from java.com and javatester.org (it's simple applets which test your Java version).
To reproduce it, go to [http://www.aleks.com/multi_applets_crash2] and click on refresh. After few times (usually less than 10 times) Java will stop and the applets won't be displayed. If you had the Java console opened at the same time, you would be able to see it close suddenly. No Java icon is visible in your Windows system tray.
We tested with Windows XP, Vista and Windows 7 and with different versions of Firefox (4.01.1, 3.018, 3.5.10, 3.5.15, 3.6.3, 3.6.13 and 3.6.17). With Java 1.6.0_25, it always crashes.
If you test with Java 1.6.0_24 it does NOT crash.
If you test with other browsers (IE and Chrome) and Java 1.6.0_25, it almost never crashes.
Any help to fix this issue would be greatly appreciated. If you think I should post this somewhere else, please advise (I have also posted this issue on bugzilla.mozilla.org: [https://bugzilla.mozilla.org/show_bug.cgi?id=654847]).

Is it ok to download the latest java update:

Is it ok to download the latest java update? I thought I had heard of a problem with them?

The Java 6U35 (1.6.0_35) that you currently is rather old, so you should either update to the latest Java 6U41 or Java 7U15 version to be protected against security vulnerabilities.
You can find the latest Java version on the Oracle website.

Why can't I run the latest Java on Firefox to operate my network camera? It does not find Java. Please Help!!

I just installed a network camera in my home correctly and signed in to view what was on the camera. But after logging in , info comes up with" cannot find Java" with an install button. I have the latest update of Java and the Firefox browser. There is no red block in the search bar that asks me to allow the site to use Java nor does it ask me to allow the site. I did uncheck the box in the control panel as it tells me to do in Java so that it asks me to use Java. Nothing works. I am so tired of installing and uninstalling, clearing my cache. Opening and closing my browser and reading info to fix this. I just want to be able to view what my camera films. Nothing on the firefox site answers or solves my problem. And believe me I've tried til my head is spinning. Someone has to have an answer. I need a vacation after this...Lol...
Thanks...

The Java plugin doesn't show in the System Details List.

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.
