New tips for Java developers

Hello to all Java developers!
Im new to the forum and I wanna say all of you hi. Wanna give you a link to one very interesting article on java development (Video Conversion System Implementation)
http://techzone.enterra-inc.com/video/video-conversion-system-implementation/
I want to discuss it with you here.

In what way is that a tip for Java Developers? In what way is it related to Java Programming?

ABAP for Java Developers

Hi,
I'm a Java developer that developed some Java Web Dynpro for my company.
Unfortunately my boss said to me that we don't have work to do on Java Web Dynpros and told me to learn ABAP Web Dynpros.
Is there any resource or quick reference for Java Programmers (who knows object oriented programming and how to make a Java Web Dynpro) to learn object-oriented ABAP and what are the differences in writing an ABAP Web Dynpro?
Thank you,
Pietro

TODAYS LITTLE CHALLENGE FOR JAVA DEVELOPERS!!!

This challenge is related to EventListener.
I initialized a String i.e
String data = "myname";
What i wnat to do;
whenever the string data changes some event generate's so that in Listener
method i received the the data .
What kind of Listener should be used i not no.
Be sure not to initialize like this "static String data = "myname";
Example:
String data = "myname";
data.add...Listener(this);
for(int i = 0; i< 10; i++)
data = "myname"+i;
public event...Listaner( Event ...e)//Event listener
string s = e.getdata();// OR some other function
Thank's

First, I think this is a cool idea, and there is a new language specifically designed to achieve this kind of event programming.
Second, I don't think this can be done with the Java language, at least not with the current Java architecture. Among the few problems implementing this, the greatest obstacle is here:
String data = "myname";
data = "myname"+i;Now, to event trigger this data = "myname" + i; , or to the JVM data = new String("myname" + i); , is problematic. The String variable data did not change value, it changed its reference. You can not intercept the = operator in Java. You can not change the String constructor behavior legally. (Well, even you do, it applies to all Strings and not just the data variable).
So, the only work around solution to achieve a similar effect is to wrap the String class to a MutableString class. (Note: wrap, not extend) And expose get/set method for this wrapper string class, then you can do whatever listener in the get/set method of your class. However, you still can not add listener for object reference change.
The above is only my take though. Do you have the answer to the challenge? I would love to hear others or the answer.

Physics for game developers book. I need to know something about this book.

1. On Amazon, the discription says it is for people with college leval math. I am only fourteen, so that won't work for me.
2. The examples are in C++
I don't care if the book is in Java, but I need a good book on game DESIGN. Is this a good book:
Game Design: The Art & Business of Creating Games
by Bob Bates. I really need to know. Thanks. Are there any other good game DESIGN books? Preferably one that is either JAVA or not made for a lanquage. Thanks.

Basic physics equations etc. isn't that hard - GCSE
maths and science is enough to get a basic physics
demo up and running. If you've not covered these areas
yet you'll want to look into trigonometry (sin, cos
etc.) and the equations of motion (dealing with speed,
acceleration etc.).This is not true.
Figuring out the forces will give you some set of equations that relate accelerations, velocity and positions with some properties of the physical system you have. This is a system of second order differential equations, more or less complicated to solve, if you want to get position and velocity over time from it.
To solve this symbolically or to be able to write an algorithm that solves this numerically is something you learn at University, except for some very easy cases.
The book explains some of this.
Look at it but don't despair.
It is good enough if you get a physics engine in your hands, thus some ready coded routines that do the job of solving for you.
I believe that book has some.

Marc

What will Windows Vista mean to Java Developers?

I just happened to read my first article on Vista today.
More specifically this awesome (and scathing) top 10 list by
Windows competetitors:
http://www.informationweek.com/story/showArticle.jhtml?articleID=195900152
It made me wonder, though itll take 2-3 years before we see
widespread adoption of Vista by anyone what does this mean for
Java developers?
Do you think the new graphics engine will mean cool new Swing
components?
Is Sun working on a new Windows JVM?
As David Girouard from google points out theres a huge uprising
in open source software, so anyway i think Java will become even
more relevant.
My number one curiosity!!!
Will Java be able to take advantage of this new Vista desktop Gadgets stuff?
http://en.wikipedia.org/wiki/Windows_gadgets
I think that would be a great area for new Java development.
Really fun things could be made.
In researching it though it seems like a ripoff of Yahoo Widgets
which Wikipedia claims is a JavaScript engine.
http://en.wikipedia.org/wiki/Konfabulator
So though Java and JavaScript are hardly the same thing,
it seems like its been down and could be done better in Java ; )
If Gadgets is a Windows OS dependent thing it would be nice
to see Java support for it. THough i guess it would have to be
3rd party and not part of the core libraries.
Best Quote Ever: "Our friends up north spend over $5 billion a year on R&D, and yet these days all they seem to be able to do is to try to copy Google and Apple," CEO Steve Jobs said in August at Apple's Worldwide Developers Conference.
Ive seen a lot of lame trolls around lately. I figured a fun conversation is what the forums need lately ; )

It made me wonder, though itll take 2-3 years before we see
widespread adoption of Vista by anyone what does this mean for
Java developers?Not much. Java runs on almost anything, and also on Vista.
Java on Vista: Yes, it Works (Chet Haase's Blog)
Do you think the new graphics engine will mean cool new Swing
components?I'm sure that there will be people who'll write cool new Swing components.
Is Sun working on a new Windows JVM?Sun is working on a new JVM all the time! Java 6.0 is due to come out in December and they're already working on Java 7.0 also.
There's no need to write a completely new JVM for Vista, as the current version of the Windows JVM already runs on Vista.

XML parser for Java setup

I download the XML Parser for Java 3.2.1 Release from the IBM site and I have JDK1.3 installed on my Windows 2000 PC. I've placed the files "xerces.jar" and "xalan.jar" in the location specified by the extensions mechanism (i.e "C:\JDK1.3\jre\lib\ext\").
I downloaded an example where java uses XML but I get an error because it fails to import the following class:
import com.ibm.xml.parser.Parser;
Also in another application the same thing happens with this class:
import com.ibm.xml.parser.TXDocument;
If I remove the xerces and xalan JAR files from the directory mentioned above I get move errors so I presume I have the files in the right location. Do I need to place any other files in that DIR other than the xerces and xalan JAR files?
Any help greatly appreciated!

Not sure if you solved your problem.
I think Xerces was handed over to the Apache organisation by IBM and the package names were then changed so that com.ibm would have become org.apache or whatever. At a guess nobody got round to changing the examples.

Error for Java 7 install

I am having serious issues in downloading Java7. Is anyone willing to offer any helpful tips on an easier process?

Hello Célia,
indeed SAP GUI for Java has not been released for all editions of Vista.
You can workaround the problem however by running cmd.exe located in system32 with the "Run as administrator" item from context menu and launching the installer from there with "java -jar PlatinGUI....jar". Then it should install as expected.
Please keep in mind, that you are then running it on a platform not officially supported.
Best regards
Rolf-Martin

I have OSX 10.7.5. I loaded Powerschool, this sent me to oracle to load java 7, now powerschool won't laod, java 7 logo just spins. I contacted orgacle live help, said it was a mac problem that they could fix for $75. Any help would be wonderful. MT

Pearson put out a tech note on this today - the new versions of Java are what's causing the problem. If you can use Time Machine to rollback java prior to a java 7 or 1.6.0_37 version that will get you going again. I've been searching for hours for a place to download the older version but it seems Apple's site and Oracle all only have the latest release. Still trying to see if I have a copy downloaded on a system that hasn;t been updated to copy off to a network drive or usb and install the older version on to systems.
PowerSchool Tech Notes
PowerTeacher Gradebook and recent Mac OS X Java update
An update to Java for Mac OS X was released on October 16, 2012. An issue has been identified with this Java update (Java for OS X 2012-006) which prevents teachers from launching PowerTeacher Gradebook.
Teachers using PowerTeacher Gradebook should avoid taking this Java update to version 1.6.0_37 until notified that PowerTeacher Gradebook has been certified with this latest version of Java 1.6 for Mac OS X. PowerTeacher Gradebook will continue to work on Mac OS X workstations with Java version 1.6.0_35.
Additional communication will be provided once a workaround is identified or an updated version of PowerTeacher Gradebook is available.

Great News for Java Game Developers!

Finally, a complete game engine is being developed for Java! Mind2Machine is developing a genre-neutral game engine that goes way beyond a simple 3D Library.
The engine is called: OpenMind Alpha v0.7 and includes many useful game programming libraries. Say goodby to C++ and complicated engine builds/API's.
Mind2Machine is currently working on OpenMind v1.0 and they need experienced Java programmers to help develop new items. There are a lot of libraries on the drawing board, here are just a few:
-Java Physics engine
-All purposes particle system
-Collision detection
-And much more...
OpenMind is open source and is developed under the LGPL license.
I'm trying to get the word out, because I believe we could all benefit from this engine.
If you're interested in the engine and/or you would like to contribute to the development of the next version(s). Please visit their webpage:
http://www.mind2machine.com/gb/openmind/index.php
Check out their developers link, and spread the word!

I got openmind, and started to install it... and then 20 minutes later I realized I hadn't really gotten anywhere and I had to download other software just so that I could install the rest of it, and that software had its own set of bogus instructions... so I got pissed and closed it all :P

Just remember that this book is for JC 2.1 not 2.2.1. I have still found this book good for explaining the fundamentals of Java Card development. It just doesn't cover all of the JC 2.2.x API's.

Which book is good for java certification 5

Hi All
I wish to be recommend a good book for Java 2 Certification Study Guide for SCJP.
Hopefully it is a book with good explanation.
regards
Tj

Hello;
I ran a SCJP5 study group at my work to get us all certified. We went with with Sierra, Bates book. ISBN 0072253606. The group found the book very useful and clear in understanding.
Most in the study group were vetran Java developers without any certifications. There was one or two that were learning Java. All of us had our annual bonus depanant on passing the cert. We were all highly motivated.

Hello,
Just a quick question: can we have an official position from Sun regarding support of earlier releases of Solaris with Java RTS 2.1? Our customer is currently running Solaris 10 Update 3 with current Recommended patches, and the 2.1 beta cyclic driver supported this version of Solaris. However with the official release version of 2.1, support for U3 disappeared (only U4 and U5 are now supported). Aside from "rubber stamping" the Solaris build via /etc/release, is there a technical reason why U3 is no longer supported? As long as our kernel is up to date, can we safely use 2.1? Or is it just a case of being unable to officially support and test so many releases of Solaris?
Is this a general rule-of-thumb we can expect in future: only supporting the last 2 updates of Solaris 10?
Your advice is appreciated.
Thanks,
Dave.
