Windows XP and Java

Hi,
If I install Windows XP over my Windows 98 will my dos be taken off the system? And if so how would I run my Zava apps from a dos prompt?
Thanks

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.

The issue doesn't appear here. Ever.
Although I rarely use I.E., the JVM always starts when needed.
I more commonly use Mozilla's Firefox browser.
This computer initially had Firefox 3.x installed to it, but it recently had that upgraded to Firefox 7.x

Windows messages and Java

Hi there,
I'm currently converting a C++ application into Java.
My main problem is that the C++ application uses windows messages to communicate between functions.
For the C++ users it uses SendMessage() and PostMessage() methods to do this.
My main question is, is there a equivalent in Java to do this, so sending and retrieving windows messages in Java.
Thanks in advance....

Sorry, you're confusing me (not that it's hard to do).
You're throwing out "application", "server", and "client" in such a way that it's hard for me to understand exactly what you're doing.
When you say "server", it makes me think of a Java app that is started and stays up, listening on a particular port for a particular protocol. Other machines on the network are the "clients" in this case. They agree to send messages using the agreed-upon protocol to the "server" listening on that port.
"send and catch messages between programs" doesn't sound like they're running in the same JVM. These sound like networked objects.
You can use Java's RMI to set up distributed objects that use RMI-IIOP as the default protocol.
Is that what you want?

Windows Vista and Java

A contact of mine is trying to learn java programming and has started with the Herbert Schildt book Java A Beginners Guide.
His OS is Windows Vista onto which he has installed NetBeans and Eclipse.
He has asked me for help but even though I am a programmer I only use Linux so am not sure that my Vista skills are adequate other than fixing his PATH environment.
His Java version is:-
java version "1.6.0_18"
Java(TM) SE Runtime Environment (build 1.6.0_18-b07)
Java HotSpot(TM) Client VM (build 16.0-b13, mixed mode, sharing)
His 1st program is:-
/* This demonstrates a variable.
call this file Example2.java.
Class Example2 {
public static void main(String args[ ]) {
int var1; // this declares a variable
int var2; // this declares another variable
var1 = 1024 // this assigns 1024 to variable 1
System.out.println("var1 contains" + var1);
var2 = var1 / 2;
System.out.println("var2 contains var1 / 2: ");
System.out.println(var2);
}but
javac Example2
error: Class names, 'Example2', are only accepted if annotation processing
is explicitly requested
How does he fix this?
BTW The above compiles and runs fine on my Ubuntu system....Smile

Windows 7 and Java

Hey,
I have been testing my applications I have written in java since Windows 7 RC's had first started being released.
Finally after installing the retail ultimate edition... the results from Java GUI related stuff is still as it was since Windows 7's first release.
Resizing of JFrame's gives a serious flicker on GUI especially when using substance look and feel, (black background beneath the standard gui)
For example, resizing net beans in xp is perfect, but resizing it in Windows 7 gives a black background and an extremely slow repaint.
I hope this gets resolved soon... is there anything being done or some sort of work around?
thanks!

hii,
nb supported Vista on "http://www.netbeans.org/community/releases/67/relnotes.html#system_requirements",
1/ be sure that's win7 is 1.st service pack for Vista, nothing else, vista core 6.0 and win7 core 6.01,
2/ xp and vista is strict only 32-b,
3/ have you win7 - 32-b, or 64-b
4/ JVM 6 for 32-b or 64-b "http://java.com/en/download/faq/java_win64bit.xml"
5/ check if is JDK and SDK correctly instaled, (JDK 6)
6/ nb correctly runs on win2003 64-b(xp core) or win2008 64-b (vista core), JVM 6, JDK 6, JDK 5,

Windows xp and java.exe problem

Hello all..
I tried to execute have a batch file consisting a jar file and classes in windows xp platform. I used j2sdk1.4.0_03. All my classes are stored in : C:\MyDocument\Softwares\classes directory
and the jar files are in: C:\MyDocument\Softwares.
I wrote the following commands in the batch file:
java -classpath C:\MyDocument\Softwares\classes;
C:\MyDocument\Softwares\jexcelapi.jar mainClass
When I lauched that batch file, a message came out:
java.exe has encountered a problem and needs to close. We are sorry for the inconvenience.
Could you tell me where the problem is and why? Do I need windows xp patch to eliminate the problem? And where can I find that patch?
Thanx for any suggestions...
Richard

Thanks for your comments. I have tried to reinstall the J2SDK, but then another error message appeared:
Error occured during the initialization of VM
java/lang/NoClassDefFoundError:java/lang/Object
I've checked my Path and it's set as following:
C:\j2sdk1.4.0_03\bin;
and my classpath setting:
C:\MyDocument\Softwares;C:\MyDocument\Softwares\classes;C:\j2sdk1.4.0_03\lib;
When I tried to execute the java command in any directory (inclusively in C:\MyDocument\Softwares) I always got that message. The only directory where I was able to run the command is in C:\j2sdk1.4.0_03\bin;
Before I did the reinstallation, I never had such a problem.
Have any hits? Thanks in advance..

Synchronized between Windows File and Java

Hi' could anyone help me..i have problem like this :
i have folder named javatutorial in my C:\ , i try rename that folder name into myjavatutorial and read the new name (both operation rename and read using my java program)
this is my code :
File x = new File("C:\\javatutorial");
x.renameTo(new File("C:\\myjavatutorial"));
System.out.println(x.getName());why java always print the old folder name?
if i see it in windows explorer the folder name already change. Why Java cannot synchronized between the new name and the old name? what i want java can print the new folder name...how to implement this?
i hope my question easy to understand...
thanks a lot...

public myProgram()
File x = new File("C:\\javatutorial");
x.renameTo(new File("C:\\myjavatutorial"));
File[] file = x.listFiles();
for (int i = 0; i < file.length; i++)
     System.out.println(file[i]);
if between x and C:\javatutorial have the same path, it will print :
C:\javatutorial\a
C:\javatutorial\bNo it won't because it won't compile.
This will:import java.io.File;
public class RenameEg {
     public static void main(String[] args) {
        File x = new File("C:\\javatutorial");
        x.renameTo(new File("C:\\myjavatutorial"));
        File[] file = x.listFiles();
        for (int i = 0; i < file.length; i++) {
             System.out.println(file);
}With the following outputC:\>dir javatutorial

To list the files of the renamed folder, you will have to create a new File

Windows xp and Java SDK

Hey
I just got a new computer with Windows XP on it and I installed Java SDK on it. I can compile my programs but I can't run them i get this:
Exception in thread "main" java.lang.NoClassDefFoundError: hate
even though there is a .class file. I was wondering if anybody have the same problem?
Thanks

Do a "echo %CLASSPATH%" at the DOS prompt...You should see the directory in which you installed Java...
Example:
CLASSPATH=c:\j2sdk1.4.1;.; where (".") = the current directory.
Your JVM cannot find the class file because you have not set the CLASSPATH enviroment variable. Your PATH enviroment variable sounds like it is ok because your OS(Windows, etc) is able to find the java, javac, jar, etc commmands.
Hope this helps.

Windows locale and Java

Hi,
i have a problem with NumberFormats and languages on a Windows system:
i want to have (for example) English GUI texts (i made some GUI forms using the IntelliJ GUI designer),
but i want to have the NumberFormat from the Windows locale (for example German/Swiss format).
The switching between the text languages works well, but i have to use -Duser.language for that purpose since only
then the GUI designer is able to use the correct gui_de or gui_en.properties file.
The problem now is that Locale Default = Locale.getDefault(); does not return the language from the Windows settings,
but the language from the -Duser.language setting which i gave the VM. Ok, its logical.
But i need the "initial" language from the Windows locale (the one its been before the -Duser.language overwrites the language)...
regards
BB

The switching between the text languages works well, but i have to use -Duser.language for that purpose since only
then the GUI designer is able to use the correct gui_de or gui_en.properties file.due to-Duser.language you will not get the correct Default Locale.
For workaround u can try below solution
Sync. your System Locale setting with -Duser.language and it is logically true.
If your System Locale is en_US
then your VM optional argument should be -Duser.language=en
if your System Locale is fr_FR
then your VM optional argument should be -Duser.language=fr
I think it will be solve your problem.

Windows look and feel instead, in InternalFrameDemo.java

Hi all, I am learning swing and I am trying to modify the
InternalFrameDemo.java source from
http://docs.oracle.com/javase/tutorial/uiswing/examples/components/index.html#InternalFrameDemo
My idea is to add the line
JFrame.setDefaultLookAndFeelDecorated(true); in the constructor, but it doesn't work
and I don't understand why.
Could somebody please help me?
Kindest regards,
Lasse
public InternalFrameDemo() {
super("InternalFrameDemo");
//Make the big window be indented 50 pixels from each edge
//of the screen.
int inset = 50;
Dimension screenSize = Toolkit.getDefaultToolkit().getScreenSize();
setBounds(inset, inset,
screenSize.width - inset*2,
screenSize.height - inset*2);
//FDoesn't work
JFrame.setDefaultLookAndFeelDecorated(true);
//Set up the GUI.
desktop = new JDesktopPane(); //a specialized layered pane
createFrame(); //create first "window"
setContentPane(desktop);
setJMenuBar(createMenuBar());
//Make dragging a little faster but perhaps uglier.
desktop.setDragMode(JDesktopPane.OUTLINE_DRAG_MODE);
}

Uh I think you're mistaken. Whenever in doubt or something doesn't work as expected, check the javadocs. The link to the javadocs can usually be found really easily by typing "java 6 classname". In this case:
http://docs.oracle.com/javase/6/docs/api/javax/swing/JFrame.html
If you want to set the Windows look & feel as your thread title suggests, this was not the method you were looking for as the javadocs will tell you. That method controls if a frame is decorated or not (as the name suggests), which it is by default. Setting it to true will not change anything.
So what then? You type into Google "java swing windows look and feel". Without quotes of course.

Data transfer B/W parent windonw and child window with out java script

hi ,
i am using h:outputLink Tag to open child window , i am unable to pass parent window text box value to child window with out java script , Here i am using two different backing beans for parent and child windows . Plz help me .

Hi -- I pass details between pages regularly. The following has worked for me:
ApplicationFactory factory = (ApplicationFactory) FactoryFinder.getFactory(FactoryFinder.APPLICATION_FACTORY);
ValueBinding binding = factory.getApplication().createValueBinding("#{beanName}");
BeanName beanProperty = (BeanName) binding.getValue(FacesContext.getCurrentInstance());
... then set the you can set the values. Can't recall if I need to use SaveStates for the items. Probably if you use request scope beans.

I'm afraid few if any of us are going to know anything more about connecting to Windows Server than you do. All I can suggest is to check if its client interface is publicly documented and try reverse engineering it from that.

How to create windows users and groups from Java

Hi,
Can any one please tell me, which Package/API will helps to create windows users and groups from Java.
Thanks,
M.Prem.

You can't do it with pure Java, and it's not in the core API. You'd have to write a native function to do it, using whatever API Windows provides, and then call it with JNI. Or look for a third party native-based Java library that already does that.

Start and Stop a Windows Service From Java

Is there any way to start and stop a Windows service from Java? The only post I found on it (http://forum.java.sun.com/thread.jspa?threadID=647509) had a link to one of the many aps that allow Java programs to be services, which is not what I am interested in doing.
I am attempting to get data from performance counters from the Windows Performance Monitor into a Java ap without using JNI. I can get the data from C++ or a .net language pretty easily and was going to create a service that would listen for socket requests and feed back the data. However, I'd like to start and stop that service when my java code starts and stops. Is this possible? Would it make more sense to just use a .exe and Runtime.exec()?

If it's only to start or stop a service then you could use the net command without any need for JNI.import java.io.*;
public class MsWinSvc {
    static final String CMD_START = "cmd /c net start \"";
    static final String CMD_STOP = "cmd /c net stop \"";
    public static int startService(String serviceName) throws Exception {
        return execCmd(CMD_START + serviceName + "\"");
    public static int stopService(String serviceName) throws Exception {
        return execCmd(CMD_STOP + serviceName + "\"");
    static int execCmd(String cmdLine) throws Exception {
        Process process = Runtime.getRuntime().exec(cmdLine);
        StreamPumper outPumper = new StreamPumper(process.getInputStream(), System.out);
        StreamPumper errPumper = new StreamPumper(process.getErrorStream(), System.err);
        outPumper.start();
        errPumper.start();
        process.waitFor();
        outPumper.join();
        errPumper.join();
        return process.exitValue();
    static class StreamPumper extends Thread {
        private InputStream is;
        private PrintStream os;
        public StreamPumper(InputStream is, PrintStream os) {
            this.is = is;
            this.os = os;
        public void run() {
            try {
                BufferedReader br = new BufferedReader(new InputStreamReader(is));
                String line;
                while ((line = br.readLine()) != null)
                    os.println(line);
            catch (Exception e) {
                e.printStackTrace();
}Regards
