Windows under a Java programm

Hello,
how can I implement Windows of instructions with a Java program?
A program steer, without being even active. Separate only
over a Javaprogramm. How can I Windows Shut down??
Thanks

i will Windows from a Java application Shut down.You want your Java program to tell Windows to shut down?
(Damn Germans and their word order.)
You cannot do that in pure java. You have to write native code for it. So you need to a) read up on JNI to find out how to include native code in your java program, and b) go to a Windows-specific place and find out how to tell Windows to shut down, and c) sew it together. (Sorry, I can't help you with any more details.

Can we run java programms on Windows XP?

Hi experts..
I installed JDK on Microsoft Windows XP Home Edition..but i am unable to run java programmes.
can i run java programmes on Windows XP?? if so how??
i will be very thankful..if any one solve this problem..

Yes, you can. There's a bunch of things you need to do (mostly setting the path environment variable). You should look at the documentation that came with the JDK, and check out the many forum responses to problems in setting up the JDK on Win 2K and Win XP.

HT1343 how do I switch between windows in the same programme? I know that I can use Command tab, however this takes you through all of the programmes that I'm using. What I need to do is have a shortcut to switch between windows in the same programme.

how do I switch between windows in the same programme? I know that I can use Command tab, however this takes you through all of the programmes that I'm using. What I need to do is have a shortcut to switch between windows in the same programme. For example if I'm in Excel and have 5 windows open I want to be able to scroll between each window of Excel only with a shortcut.
Please help!

Command and ~ keys to tab between open windows.
Technically it is the Grave Accent ` (aka reverse quote) under the tilda ~ key. Tilda ~ is shifted, and Grave Accent ` is not.

Windows XP and java.lang.NoClassDefFoundError: Console

Our company is currently using a web page to launch a java applet that redirect the user to an application server to demo our product. This has been and still is working fine for all Windows version until XP. And depending on which version of XP, sometimes it will work and sometime it won't. The link to the web site to launch the applet is http://www.aasys.com/gs_java/iejava.htm if you wish to test it.
It should take you to a screen asking for a security code which we would provide to our customers. If you get this far it is working.
Any suggestion would be helpful.
Thanks.

Your first option we are currently looking at but have not tested it yet. We would prefer the end user not to have to do this, but they may have to in the end.
Your second option seems the best route to go and we may be able to get the source code from our vendor. Once this is compiled under 1.4.2 will it still be compatable with the older version of MS JVM or will our users need to download the current Java plugin? Since this the way that Java is proceeding this will most likely work for everyone.
Thanks.

I can not run or compile java programme

I am first time java programmer I can not run or compile any java programme.
(can not read
1 error) this is the the message that I am getting from my dos

http://java.sun.com/docs/books/tutorial/getStarted/cupojava/index.html
Try the tutorial.
It sounds like your error message comes from compiling. For example, "javac mysourcecode.java" If that is correct, the most common trouble comes from using a program like Notepad on Windows to create the soruce code. The tutorial will walk your through it.

Do java programms after giving compilation error generates .class file?

Do java programms after giving compilation error generates the .class file?
Do any outer class may have the private as access modifier?
If someone asks you that -do any program in java after giving a compilation error gives the .class file -do any class except(inner class)
be defined as private or static or protected or abc or xxx Now type the
following program
private class test
public static void main(String s[])
System.out.println("Hello!How are You!!");
-Compile it.... You must have
received this error test.java:1:The type type can't be private. Package members are always accessible within the current package. private class
test ^ 1 error
Here please notify that compiler has given the
error not the warning therfore .class file should not be created but now type
>dir *.class
___________ and you will see that the
test.class file existing in the directory nevertheless this .class file
is executable. if you will type __________________ >java test
it will
wish you Hello! and suerly asks you that How are You!! ________________!
You can test it with the following as acces modifiers and the progrm will run Ofcourse it will give you compilation error.
protected
xxx
abc
xyz
private
Do you have any justification?

Hmm,
I've been working with different versions of jdk since, if I'm not mistaken, jdk1.0.6 and never was able to get *.class with compilation errors. It was true for Windows*, Linux, and Solaris*.
About the 'private'/'protected' modifier for the type (class) - it makes perfect sence not to allow it there: why would anyone want to create a type if no one can access it? There should be a reason for restricting your types - let's say, any inner class can be private/protected.
For ex., you shouldn't have compile problems with this:
class Test
public static void main(String s[])
System.out.println("Hello!How are You!!");
private class ToTest{}
Sorry, but I don't really know where you can read up on that.

Speed of java programme in different JVM

There is a java programme.(It is a big programme.)
In MS-JVM(microsoft java vm) ,it seems to be running faster then running in Sun-JVM.
For example, it spends 6 seconds opening a frame in MS-JVM, and it spends 25 seconds opening the same frame in Sun- JVM.
Now,is there any methods to speed the programme running in Sun-jre except optimize the source ?
Sorry , my English is poor ,can u understand me?
thanks a lot in advance!

It really depends on the underlying hardware (CPU, memory, graphic card, ...).
Are they comparable?

Othere wise please suggest, is there any alternative approach for getting those details, This is very urgent, Please help me
Thanks in advance
Audippa Naidu.M

Othere wise please suggest, is there any alternative approach for getting those details, JNI will likely be involved. I promise you there is no built-in Java functionality to get data from win server, whatever that is.
This is very urgentNothing like waiting til the last minute, eh? Look, just because you say it's urgent doesn't mean anyone will help you any faster than anyone else. So don't be that guy.

Creating a New Folder in Windows Registry by java coding

Good morning,
hi to all,
how can I create a New folder in Window Registry using Java coding. Can anybody help me out pls.
I begin waiting for ur reply.
Thanx

Why do you feel you need to write to the Windows registry directly? Take a look at the Preferences class.

Opening a new URL in an existing browser window from a Java application

I've tried one of the many codes to open a new browser window and it works, but I need something else.
Is there any way to open a new URL on the same window on a Java desktop application? (Changing the URL on the current browser window without opening a new one, I mean).

You can do that by using an add-on such as:
* NewTabURL - https://addons.mozilla.org/firefox/addon/newtaburl
* New Tab Homepage - https://addons.mozilla.org/firefox/addon/new-tab-homepage
Another way of opening the home page in a new tab is to middle click on the home button in the navigation toolbar.

DVD optical drive no longer works with Windows under bootcamp or parallels

For some strange reason, the DVD optical drive- Optiarc 5680 on my 27" iMac, no longer works anymore with Windows under Parallels or Bootcamp. It used to work perfectly fine before, but now it just shows up with a yellow exclamation mark under Device Manager and Code 39 "Windows cannot load the device driver..."
The DVD drive continues to still work fine with OSX. But it won't work anymore under Windows via Parallels or bootcamp, despite trying to uninstall the optical device drivers, update, reinstall, etc. Anybody else experiencing this or have any ideas?

Finally found the solution for anybody else who runs into this problem. It was solved by doing a registry mod in Windows from this site:
http://aumha.org/win5/a/xpcd.php#problems
described in “My CD drives have vanished (from Explorer, Device Manager, etc.)”
After applying the registry changes the DVD optical drive worked instantly again with Windows....sigh...guess I can't blame the Mac on this one.

i just want to know one thing from some professionals on the forum that is it very necessary to have an SCJP Certification if i want to apply in some big companies as a java programmer since i wont be having any other certifications that i have done java .
please tell me if it would be good for me if i do an SCJP course
Regards

hi i have been programming in java for quite some

In that case you should already know the answer to your stated question...

Can't hurt, probably won't help either.
