Can anybody help me with this error?
Thanks

some of the reasons why most people get this error
The java file has not been compiled
The java class does not have a main method(Applet or servlet) and is being run with the wrong tool.
typing error for the name of the class

  • Newbie problem plz help

    Just bought my Ipod 30 Gb Black
    Went 2 a friend and put some 2 Gb of music on it
    Arriverd home and updated with my new PC (with 0 mp3 on it)
    Result:lost all my music
    Question:in info shows drive capacity is 28 Gb....why not 30 Gb??
    If i connect the Ipod on my friends PC will it show the 2 gb of mp3 ?
    Cause hes PC is recognized as "home".
    Plz help ...

    First of all, what you are attempting to do with your friend's computer is considered to be "illegal file sharing" & any discussion of how to do this on these forums is against the "terms of use". The difference in the iPod's disk capacity is due to how computer disk manafacturer's calculate disk space. The actual usable capacity of any computer disk will be about 10% less than what is given. It's normal, don't worry about as there is nothing you can do.

  • Ok another newbie problem plz help me

    Hi all, I just posted a few minutes ago where to find SDK 1.3.1 standard edition, I found and finished downloading it, I installed it, and the book I am using says the following, plz bare with me but I don't have a clue what this means cuz my comp doesnt have what that thing says. ok here it is:
    Windows NT and 2000 Configuration
    To set any environment variables on a windows NT or windows 2000 system, choose Start, Control Panel, System, Environment from the taskbar. A dialog box will open where you can view the current values of environmental variables and make changes to them.
    The PATH variable might be listed in System Variables or User Variables. PATH contains a list of folders seperated by semicolons.
    At the beginning of the PATH setting, insert the folder where you installed the SDK followed by the text /bin and a semicolon (";").
    For example, if your PATH was c:\windows;c:\command and you installed the SDK into C:\jdk1.3 your new PATH should have the following value:
    PATH c:\jdk1.3\bin;c:\windows;c:\windows\command
    After making this change, look for a classpath variable. If you don't find it, you're done configuring theSDK. Click the Apply button to save yuour changes, and then reboot your computer.
    If you do find CLASSPATH, place your cursor to the left of the existing CLASSPATH value and insert the SDK folder followed the the text \lib\tools.jar;.;
    For example, if you installed the SDK into c:\jdk1.3 and your classpaht had the value c:\javaclasses, your classpath variable should have the following value:
    c:\jdk1.3\lib\tools.jar;.;c:\javaclasses
    After setting your CLASSPATH variable (if necessary), click the aplly button to make your changes permanent, and then reboot the computerl
    Long isnt it? well anyway my path thing is completely different than what it says, when I double click it or press on edit, it gives me this:%SystemRoot%\system32;%SystemRoot%;%SystemRoot%\System32\Wbem
    and it doesnt look like anything of the stuff in the book. am I doing what it says or is there a mistake I made? if so plz tell me what I should do, no evil people plz I don't get all this stuff. :)

    For example, your PATH is %SystemRoot%\system32;%SystemRoot%;%SystemRoot%\System32\Wbem and if you installed the SDK into C:\jdk1.3 your new PATH should have the following value:
    C:\jdk1.3;%SystemRoot%\system32;%SystemRoot%;%SystemRoot%\System32\Wbem

  • Audio Clip problem plz help..

    There is some problem with my code. It is actually for simply playing a wav file.
    It gives errors on two lines....
    import java.awt.*;
    import java.awt.event.*;
    import java.io.*;
    import javax.swing.*;
    public class MediaPlayerDemo extends JFrame
         AudioClip clip; //Error Here
         public MediaPlayerDemo(String title)
              super(title);
         clip = getAudioClip(getCodeBase(),"access.wav"); //Error Here
         clip.loop();
         public static void main(String args[])
              MediaPlayerDemo m = new MediaPlayerDemo("Title");
              m.setSize(400,400);
              m.setVisible(true);
    }

    "Audio Clip problem plz help"
    You have to learn to help yourself.
    Have you done anything to try to fix the errors yourself?
    AudioClip clip; //Error Here
    the error generated here is self-explanatory.
    if you can't fix this, you should get a good book on java basics and start again.
    the other error is also easy to fix.

  • Package Problem : Plz help

    I've make two classes named First.java and Second.java in e:\javafiles\test\vg folder
    package vg;
    public class First
              public int m = 100;
              public int n = 200;
    package vg;
    public class Second
              public static void me0()
                   System.out.println("Stupid cant u see the value of m is zero");
              public static void mgrn()
                   System.out.println("Yaar m is greater than n");
              public static void neven()
                   System.out.println("The value of n is Even");
    and a Third class
    import vg.*;
    public class Last
              public static void main(String robert[])
                   Second d = new Second();
                   First f = new First();
                   if(f.m==0)
                        d.me0();
                   if(f.m>f.n)
                        d.mgrn();
                   if((f.n%2)==0)
                        d.neven();
                   else
                        System.out.println("The value of n is Odd");
    Now the problem is that if I put the Last.java at e:\javafiles\test and compile it , it works fine but if I put the Last.java anywhere else e.g at e:\javafiles and try to compile it it does not works and gives error
    E:\JavaFiles>javac Last.java
    Last.java:1: package vg does not exist
    import vg.*;
    even if I change classapth variable as E:\javafiles\test or even E:\javafiles\test\vg
    plz help me in this regard

    You need to change where it is trying to find the 'vg' package. So, if your Last.java is in e:\javafiles, then you need to
    import test.vg.*
    e.g.
    import test.vg.*;           // Change this line
    public class Last
              public static void main(String robert[])
                   Second d = new Second();
                   First f = new First();
                   if(f.m==0)
                        d.me0();
                   if(f.m>f.n)
                        d.mgrn();
                   if((f.n%2)==0)
                        d.neven();
                   else
                        System.out.println("The value of n is Odd");

    So, when i click on the itunes shortcut, which has the same icon as the Apple Software Updater, I get a box that says that iTunes has encountered a problem and needs to close.
