Java on my computer

Im having trouble trying to get this java programming program to work. It says you need a recent JDK version installed? If anyone know please help!!!!!!

JRE only lets you run compiled Java classes. You can't compile. JDK lets you compile and run (JDK includes JRE). J2SE is the Java 2 Standard Edition (as opposed to J2EE [Enterprise Edition]). The Sun download page should have some information as to which version you want.

"Detecting Java on your computer" spins forever

Hi,
Win 7 32 bit / IE 9 / Clean install - wiped the hard drive and started fresh
Installed Java 7 update 10 (1.7.0_10-b18, according to the control panel Java applet) from java.com, without any errors.
When I go into the Verifying Installation page, the "Detecting Java on your computer" applet spins forever.
Removed Java, reinstalled, restarted the browser & computer multiple times, same result.
Tried it an another PC, also Win 7 32 bit / IE 9 / Clean install - same result.
What's going on?
Thanks

Check the proxy settings, I suspect this is the problem.
This is often the cause when a class file can not be loaded.
http://docs.oracle.com/javase/7/docs/technotes/guides/deployment/deployment-guide/jcp.html#general scroll down to "Use proxy server"
If problems are still seen, view the Console output. Turn this on under the Advanced Tab.

Less likely, but possible, are firewalls, AVs, routers, etc.

How do you get the Java API onto Computer

Hi guys,
Well I want to practice Java at home, but instead have been staying up late at night at the University's Computer Lab.
I have downloaded the Forte for Java, but I don't need all the Graphics classes since my programming class is centered on Programming in the UNIX environment. Not too long ago, I purchased SuSE Linux which had the Java Language and the compiler. I successfully managed to dual boot an old computer with it. It was easy because SuSe Partitioned the drive for you if it had a WIN32 filesystem.
My parents bought me a laptop and it came with Windows XP. I have ever since wanted to Dual Boot this system with Suse Linux, but can't because 1.) SuSe Linux doesn't partition the drive because Windows XP resides on a NTFS filesystem. 2.) I can't risk doing it myself because I have a lot of critcal information.
It would be really neat to work in Linux to program, because then I could do some serious homework as well practice. Forte for Java I am not really knowledgeable of it. I can't get the editor to work and it doesn't feel like I am in UNIX at all which defeats the purpose of taking trying to succeed in this programming class.
Could somebody help me with my woes on how to deal with these matters. How can I get SuSe Linux on my XP computer safely and if it can be done how do I use the Forte for Java.
Thanks for all your support,
mileinfive-serious about programming

The first question: http://sdb.suse.de/en/sdb/html/dstark_linux_xp.html
F4J will be the same on both operating systems.. what actually is your question regarding it?

After installing recent java + security update, computer will not sleep

After installing the recent java, daylight savings, and the security update. my computer will not sleep. Does anyone else have this problem? I do have an adaptec usb2 card installed but nothing is plugged into it. Also i don't have any Ipods or external things plugged in. I have had the same setup for the past year with no problems, now it will not sleep. I have also tried repairing the permissions. Please help

When you select Sleep from the Apple Menu nothing happens, is that correct? Try this: Go menu > Home > Library > Preferences. Drag the whole of the Preferences folder to the desktop. Restart your mac, don’t worry if things look different, you have not lost anything. Can the mac sleep now? If yes, then its a damaged or corrupted .plist or preference. If you are using Apple Mail, drag the com.apple.mail.plist back to the new preferences folder created on reboot, you dont really need anything else but keep hold of the old preferences (the one you dragged to your desktop) just in case for a month or two. If everything else is OK you can safely delete it. If it has not cured the problem then remove the new preferences folder created on reboot by taking it to the trash, drag back the preferences folder you moved to the desktop and reboot. Now reinstall a clean OS. See how you go from there

Cannot create JAVA on new computer...please help

I have not been able to actually view anything I create with Java on my new computer. I have tried installing the latest update of Java but it didn't help. Sun Java was already installed on this computer.
I use Front Page to create web sites and have never had a problem before.
When I create a Java effect, I can see the Java Icon in normal view but as soon as I try to preview... nothing shows up.
The Java effects i created on my other computer show up on this computer...
please help ...

Thank you for your response but this doesn't help.This is a forum for Programming in Java. Your question appears to be targeted at something else, Digital Video maybe? Possibly Applets? We don't know, and you aren't giving enough information to make a decent guess. If you have a Java code development-related question this would be the place to post that.
Perhaps you want a Microsoft Forum?
Good Luck

New to Java - cannot get computer to compile?

Hi
I'm from UK, although I've used one for ages I am new to computing itself and very new to programming - in fact I haven't started yet because I cannot get my JDK to work!! I have downloaded it successfully, it is installed and I have verified the version from athe command prompt. I have written a programme as detailed in my Programming with Java book, and saved it with a java file extension and I am sure it is correct. But when I try to compile mit I get "'javac' is not recognised as an internal or external command, operable program or batch file"
My book has no further advice on what to do - can anyone on this site offer me any help please.
Thanks

Make sure the path to the javac.exe is specified in the environment CLASSPATH, otherwise you'll have to instruct your command window to point to the java/bin directory every time you wish to compile something... Not fun... :P
After that, just follow the instructions pointed at the tutorial...
Check out the installation doc at http://java.sun.com/j2se/1.5.0/install-windows.html , specifically, the heading: 5. Update the PATH variable (Optional)
If you're new to java, I recommend getting an IDE to simplify things: www.jcreator.com is nice and free, try it out... ;)

Java for mobile computer!

Hi!
I have a mobile computer that runs Microsoft� Windows Embedded CE. NET 4.2... I can access the Internet with it, but I can't run jsp scripts... what do I have to install in my mobile computer to run jsp scripts???
null

When you say you cannot run jsp scripts, do you mean jsp pages on the internet, if so this has nothing to do with your devise as you only need an HTML browser to access jsp, all processing is done on the server.
If you are tryinjg to run pages locally you will need java installed, and web-server software installed.
You can get Java for mobile devices, but I dont think you would get a web-server running.

Using a program named JavaBloodBowl, Java crashes my computer.

Hi, I play a game named Blood Bowl which is a Java executable file, and recently I've had a lot of trouble playing the game. The game either uses a direct IP connection or a proxy server to connect to someone else to play. However, almost every game I've played recently has caused my computer to freeze. The people I have talked to are certain the error is caused by Java. Is there some error log Java uses where I can check on the exact status of the error, or can anyone else help me as to what I can do?

I am developing a stand-alone java program. Lately,
whenever I debug or run the program it will shutdown
my computer. At first I thought it was the IDE
(Eclipse) I was using, so I switched to simple text
editor and command line compiles and runs.... it
still happened. Virus-infected files?
So my questions are:
1) If it is my program, what steps can I take to find
out why? (The crash always happens right when I
launch the program). Debug and watch whether it always happens at the same moment. But IMO it's unlikely because it's of your program.
2) Is it a memory issue? How can I find out?Could be in the sense of "defective RAM". Remove one bank. Try again. Set it back in and remove another bank. Try again.
3) Why would my computer crash when running a java
program? When I worked in C++, programs would crash
but not the computer. There was no time when my PC was booted more often than when I was writing C code in M$ VS6.

Installing java on a computer without it

I want to install java on this really old computer, 8192k ram, 1gib harddisk space. I don't care if it takes me a year to compile a file or whatever, I want to put java on it (mainly because i don't always get access to this computer). Anyway, I haven't got a clue how to install java on it. I think it doesn't have a clue what java is, so I'm going to have to install JVM, though I don't know what else I need. My computer (this one) has the Java runtime environment standard edition v.1.3.1_05, Java runtime environment 1.2, and java 2 SDK standard edition v1.3.1_05. I want 1.3.1_05 on the old computer, and I have a burner, So i'm thinking of burning the java files on that computer, but can someone tell me what files I have to burn and where they are located (in a standard installation) thx.

Open my computer
Open the c: drive
Hopefully (please god) you'll be able to see "autoexec.bat" somewhere. It may just say "autoexec". If there is more than one, right click on each one, and click Properties until you find the "autoexec.bat" file.
Right click on "autoexec.bat" and click edit. (If you don't have the option, open it with notepad)
If you have a line
set path=......
append this on the end
;c:\j2sdk1.3.1\bin
or whatever your java directory is. (make sure you have the semi-colon between the last existing path, and the one you add)
If you don't have a "set path=..." line in your autoexec.bat, add it (like so):
set path=c:\j2sdk1.3.1\bin
That should be enough to get you going (you'll have to restart for the changes to take effect)
Good luck,
Radish21

Cant run Java on my computer

Hello,
I'm running a XP pro (eng) with sp2 fully patched.
I've tried with several several versions of JRE but no matter which one I try, I can never get Java to work on my PC. Even Java control panel window apears grey to me.
[edit] Basically what happens is that I install a whichever version of JRE (lately i've tried 1.5.4, 1.5.6, 1.5.8) and after instalation I just basically try to open Java Control Panel on my windows control panel, and the window is just a slate of light grey. No tabs no nothing... just grey. [edit]
Any ideas?
TY

Welcome to the Apple Support Communities
To install the most recent Java version for Mac OS X Snow Leopard, open  > Software Update. If it tells you that you are running the most recent version, you are using the most recent Java version for Snow Leopard

Not for Snow Leopard. Java is installed as part of Snow Leopard, but not part of Lion. The latest Snow Leopard update is Java for Mac OS X 10.6 Update 8. This update also installs the anti-malware protection for the Flashback trojans.
