Up an running with Java. What tools to download?

Hello, I use to work with Java applications about three years ago, but had switched over to another language. Now I need to develop code using Java again. In fact, I need to reuse some of the code I developed a few years ago. The code does alot with animations. So here is my question.
"What tools do I need to get up and running with Java?"
1. What compiler to use (recommend the best open source editor, or one that is not that expensive)?
2. Where is the Java SDK that I need to download?
3. Will my three year old code still be compatible with the SUN, Java code I wrote 3 years ago?

Actually Jwenting is right, IntelliJ is by all measures the best IDE.
I have used textpad, programmers notepad (which I still use for some things), VIM, eclipse for a number of years, intelliJ for a short time, and Netbeans since earlier this year.
textpad - Great place to learn the basics, but once the basics are down you need to find an IDE.
Programmers notepad - love it, still use it for some languages, has some features you will find nowhere else
VIM - You have your vi lovers and your vi haters, I would say I fall into the haters camp but still keep up with it because when you need an editor to make a quick change on some obscure system with very little on it, some version of Vi will undoubtedly be there. Once you get into the flow it is not bad, but there is lots of annoying things about vi and its offspring.
Eclipse - Great IDE, was the better of the free ones for a long time. For me eclipse's strength became it's albatross. That is plugins ofcourse. There are literally thousands of plugins that can make eclipse do just about anything you want. The problem is there is very little oversite so some plugins are great, some good, some ok, some suck, and some are deliberately hostile. You don't really know what you are going to get until you try it, but removing it can be a pain so sometimes you are stuck. Plus getting the plugins to play nice with each other can be a chore, the more plugins you have the harder it gets to get new ones to play nice. It was after a whole day stint trying to get eclipse to work again after picking a bad plugin that i simply decided to give netbeans 6.0 a try since it had what I wanted packaged in already.
IntelliJ - Only got to use this for a short time as they went ahead and bought it at my last job after I gave my months notice for leaving. Guess they figured it would be easier to replace me that way. From the little I got to play with it, it was extremely user friendly to the point of being a pleasure to work with, You definitely got what you paid for.
Netbeans 6.0 and higher - Netbeans pre 6.0 sucked. Even 5.5 was not as good as eclipse at the time of it's release, but was a sign they were headed in the right direction. After releasing version 4 only to have it suck and laughed at in the java community since eclipse was hundreds of times better Sun realized netbeans was making them look bad. So they decided to fix that and decided the best way to fix it was to model netbeans as closely after IntelliJ (which was the best even back then) as legally possible. With each release they get closer to realizing this goal, and since it is free with each release netbeans picks up more and more former eclipse fanbois. It is now at the point where most people following the eclipse vrs netbeans war will agree that netbeans has taken the lead and has more current users than eclipse. I would even wager that most of the people who said netbeans was best in this thread were not long ago eclipse fans. Bottom line, of the free IDEs netbeans is the better choice at this point.
But I got to ask, when you say a salary of R8,000 - R12,000 do you mean monthly income or annually? If annually can you even survive on about $1,000 in US dollars for a year? I mean I make about 8 times that in a month, after uncle sam takes his portion, and i wouldn't call myself rich by any means.
Also jwenting have you tried the newer netbeans? I think if you do you will see they are strikingly similar to IntelliJ in many ways.

Running with java -jar

I have a client.jar that has a bunch of vm parameters and relies on a few other jars. The jar has the main class specified in the manifest. Ultimately I would like to take the dependent jars and put them in the client jar and use the manifest classpath option. I have been unable to get this to work. What I am finding is that running with java -jar basically ignores all of my vm parameters. I have tried removing the dependent jars and referencing them from the command line classpath argument. This still did not work. The only thing that has worked is not using a client.jar at all and just running my main class with all the vm parameters. This is not an acceptable solution for me. Thoughts?
Thanks,
Howard

Yes, this is what is so weird about the problem. Neither the manifest class-path option or running with cp is working when the main class lives in a jar.

Problem running with "java class"

Hi:
I developed an application in Forte. It works as expected within the IDE. I would like to run it outside the IDE with "java application.class". When I try this, it cannot find many modules. I realize I need to set the classpath, but don't know what to set it to.
Please help.
vjktm

r u using windows?
if so
try this
open up the dos
then type the following command
set classpath = drive:\directory\.
drive - your working drive
directory - where you put ur java source and class files
make sure you have the . at the end of the cammand.

JFrame running with Java Web Start

I have a problem with running my application with Java Web Start. My main application window is a JFrame and I have a line of code as below
this.setExtendedState(MAXIMIZED_BOTH);
It runs fine when run on a PC locally. But if I try to run the application through Java Webstart I get an exception. Can anyone help me with this. I would like the JFrame to open maximized.
TIA.

try posting the exception to get better answers. but anyway, i'm guessing its a security issue... your app is trying to access the properties of the local system. you might have to sign your application for this to go away.

How to get applets running with Java Plug-in on Win but also on Mac OS X???

I've converted to the use of Java Plug-in for my applets, but I need to have those same applets executable from browsers on Mac OS X platform. Surely this has been done, but I don't see how. The browsers I've tried on Mac OS X (Netscape, IE) don't seem to recognize the <OBJECT> tag used for the java plug-in. I've seen no news about the Java plug-in being ported to Macs. How can one get the same applet to run with the Java plug-in on Windows browsers, and also to run with at least one of the common browsers on Mac OS X? Any help would be SO much appreciated!

Those ten dukes look good to me. But the passing of fifteen months has me thinking you've probably moved on. In any case, here's my effort.
I've been through a trial trying to get my applet, developed with 1.4.1_03, to run on my Mac OS X v.10.2.6 in multiple browsers. I'm posting my results here. Comments and feedback are welcome.
JVM support for 1.4.1 is limited to the Safari browser. All other browsers running in Mac OS X that I've tried ( Camino, Opera, Internet Explorer, Mozilla ) are using the 1.3.1 plugin. According to a bug report by Mozilla on this topic ( see Bugzilla Bug # 197813 http://bugzilla.mozilla.org/show_bug.cgi?id=197813 )
with the release of Apple's version of Sun's Java 1.4.1 the applet programming model has changed, and only Safari has adapted with this change. Other browsers, according to the report, could not because of a lack of documentation. The use of the MRJCarbon plugin offered by Mozilla (here - http://www.mozilla.org/oji/MRJPluginCarbon.html) only allows Mozilla to use the J 1.3.1. And I have not found any information on the Microsoft site about how to get IE 5.2 to recognize the newer version of Java.
Regarding the use of the OBJECT tag in Safari, it is a matter of debate. A current post on this topic exists in the Applet Development forum:
http://forum.java.sun.com/thread.jsp?forum=421&thread=441002
In my experience, I have not been able to determine that Safari v1.0 recognizes the OBJECT tag. My experience is that the APPLET tag is required to run applets in Safari. The Bugzilla report echoes the problem with the BadMagicNumber error that can arise in Safari. Nonetheless, I enjoy Safari and I enjoy Mac OS X.

Err. in programs copiled with Jdev 9.0.3 and run with Java Web Start

Hi all,
when I build my programs with Oracle9j JDeveloper 9.0.3.988 and I use them with Java Web Start, programs do not run, while when compiled with Oracle9j JDeveloper 9.0.2.x it runs without problems.
The Java version used in both cases is 1.4.0.

Hi There.
We had the same problem with some of our code. We moved the definition of the class from a method out of the method. Like this:
public class{
class{
instead of doing this:
public class{
method() {
class{
This worked with the web start......

How to make sure an applet runs with Java 5?

Hi all,
First let me say thanks for all the help in the past. You've help me go from noob to intermediate noob. I've just about finished my first applet game which can be checked out here .
Now I've been reading about problems with mac and 1.6. (note it works on Linux). I want to make sure that it runs fine and of course I don't own a mac. So I downloaded the 5 JDK. Selected it as the java platform in Netbeans, compiled and it ran fine.
Questions:
Do I have to always use 1.5 to compile and perhaps set it as default?
Since it works in 1.5, do I compile it with 1.6 and just upload?
I'm worried I'm not testing it correctly. I mean if I have both 1.5 and 1.6 installed on my machine, how to I make sure the applet is only using 1.5 to run?
Thanks
Darrin

I haven't got a clue RE your problem other than for max-portability you should compile with [-target 1.5|http://java.sun.com/j2se/1.5.0/docs/tooldocs/solaris/javac.html].
I must say I'm impressed, except I suspect my PC must be substantially faster than any of your test platforms... can you throttle it to CPU performance somehow? Or maybe it's just that my reflexes aren't what they once where.Thanks.
There seem to be two issues. The first is what people are using. This web stats shows pretty poor penetration of 1.6.
[http://www.statowl.com/java.php|http://www.statowl.com/java.php] Penetration: 54% with JRE1.6 + 19% with JRE 1.5. Total 73%.
The second is I've read that mac and 1.6 do not get along except on a 64bit platform.
So for applets there is not much choice but to compile on 1.5 for the broadest user base. I guess the good news is 1.4 and earlier are almost non-existent.

Problem installing program running with Java

When i start to run a program appear a window witj following message: "preparing to run java virtual machine"..after that appear next small window with installshield wizard. When make a transition between this small windows to start to install the program, nothing happens it is he does not make this transition.
I already download the new version without results.
Do have any ideia what could be the problem.?
Thanks
Jorge

Which JRE is bundle inside your application ?
Is it International or US only ??
I have a reason to believe that US version is
throwing NullPointerException when installing it
on windows 2000 server
When you starting the installer, The installer is unpacking the JRE - so check which directory it expanded and than Try running java.exe from the JRE that was installed.
Maybe its currupted, You dont need to run any code
even if your run java.exe without anything the
exception is thrown
If exception is thrown try the international version of JRE

Will compiled 1.4.2_12 will run with java 1.4.1_5

Dears,
I'm deploying my target application on HP non-stop Tandem server which is using 1.4.1_5 and I can't upgrade for some technical issues and other application using this specific version.
My development environment, I'm using jdk 1.4.2_12 on Windows.
My question -as I couldn't find any windows version for Java for 1.4.1_5 as all for 1.4.2-:
- Will my code run without problems on production, and without need for re-compilation?
- From where can I downloaded JDK 1.4.1_5 for windows?
Thanks for your time.

it should run, but there might be subtle differences in how it's executed so test thoroughly.
P.S. if you couldn't find a place to download 1.4.1, look again. Every release from 1.1.6 onward is available from the archives would you want them).

Can get anything to run with java....

Yes.. I've updated my Classpath.. but every JAVA program that
I compile and when I executer java myprog.class it get's an
error on finding that very class...
What's the problem..?

ONE: Paste this into Notepad;-
public class HelloWorld{
��public static void main(String[] args) {
��System.out.println("Hello World");
��}
TWO: Open the MSDOS Console and NOTE WHICH FOLDER on your C-Drive you are in.
THREE: Save the above on your C-Drive as HelloWorld.java (exact same case, ie: capital 'H' etc and) IN THE SAME FOLDER as the Console displays.
FOUR: Type this (exactly the same!) in the MSDOS Console
javac HelloWorld.java
FIVE: Tell us what happened.

WebLogic 8.1 SP4 fails to start on FC4 with Java (GNU libgcj)

Hi,
When I use the Java JVM which comes with FC4, my WebLogic server (8.1 SP4) will not boot.
NB It boots with the BEA jdk (also a 1.4.2 version)
I choose the FC4 Java JVM, because then the MySQL's driver mysql-connector-java-3.0.16-ga-bin.jar will work. (Checked
with a simple java program). But the WebLogic server runs off the rails.
Here is the output of ./startWebLogic.sh :

The Exceptions before originate from a small java program.
I tested the working of the mysql driver with a small java program as I got these Exceptions when testing a Connection Pool in WebLogic.
The problems with WebLogic and databases started when I used the pointBaseConsole.sh script.

SQL-Server rejected eshtablishment of SQL-connection. Pointbase Server may not be running at localhost at port 9092. NB Of course I have started the Poinbase server. It says it was listening at port 9092
I get these Exceptions both wtih opening an existing (demo) database as with creating a new one.
Here is the small java program: It is compiled/run with java (1.4.x) from FC4 and with java 1.5 from SUN. Both versions worked successfully.
import java.sql.*;

public static void main (String[] args) throws SQLException {

Help with Java Web Start

Hi everybody,
I have a simple Java application that has a JFrame containing a TextField displaying some text inside it. I am using the NetBeans IDE. I am trying to Enable Java Web start for this application. The steps I have taken upto now are:
1. Right click on Project, Java Web Start -> Enable Java Web Start. This created the jnlp file.
2. In the Resources section, I added the jar file for swing. ( I am not sure if I have to add the path for jnlp.jar etc, or are these found automatically?)
3. Right click on Project, Java Web Start -> Deploy with Java Web Start. This launches the browser with the Click me link, but on clicking this link, I get the following error.

I am not sure what it has to do with servlets, I just followed a tutorial on using Netbeans with Java Web Start, and did only the steps as mentioned in my first post. And ended up with the error.
Anyways, I added the jnlp jar files(jnlp.jar, jnlp-servlet.jar, jardiff.jar) in the WEB-INF/lib directory. And it seems to deploying it now. I can get my application to load on clicking on the "Click me" link. But the controls on my application don't seem to be working.
Also, when I try to Right click on my project -> Java Web Start -> Run with Java Web Start, I get the following error message,
javaws-run: C:\Documents and Settings\Lux\Visualization\nbproject\build-jaws-impl.xml:36: Execute failed: java.io.IOException: CreateProcess: C:\j2sdk1.4.2_13\bin\javaws "file:///C:/Documents and Settings/Lux/Visualization/Visualization.jnlp" error=2

Any help appreciated.
