Instance of a Main Class

Hi guys,
I need to create an instance of the main class in my project.
This main has the standard main method : public static void main (String args[])
,which requires a character by command line.
How to create an instance of this class from another class in the same project passing the required parameter ??
Note : I'm using this to test the class , with Eclipse and Junit
Thanks a lot

Same way you create any other class. Except "main" is a static method, so you don't need to create the class. Just call the following:
Main.main(new String[] {"FirstArg", "SecondArg", "ThirdArg"});Where Main is the class with your "main" method. You can build up the String array separately, and then pass it as the argument to "main" (as you would for any other method that takes a String array).

Referencing main class from created instances

The quick setup:
My Main class creates a JFrame and adds a few custom JPanels. One of the JPanels has a mouse listener and responses to the mouse clicks, and it works great.
I'd like to know if there's a way to have that JPanel invoke public, non-static methods from the Main class (the class which created it) without passing a reference for the instance of the Main class to the JPanel when it's (the JPanel) is created. Or is that the way you're supposed to do it?
A (sort of) similar question: can a component invoke methods of it's parent container? If so, how?
Thanks so much,
Matt

Hi Rhesus21,
A (sort of) similar question: can a component invoke methods of it's parent container? If so, how?Yes, simply this way :
public class MainFrame extends JFrame {
    private MyPanel panel;
    panel = new MyPanel(this);
public class MyPanel extends JPanel {
    private MainFrame frame;
    public MyPanel(MainFrame frame) {
        this.frame = frame;
}

Execute jar file: "could not find the main class" program will terminate

Hey,
I am new to Java. I have started to make a small java program which supposed to help me at my studies to lean the Dominic Memory System. I have used the latest version of Netbeans 5.5.1 to build my program in. I have two problems which I cannot figure out how to solve, please help me.
The first problem is that the java script I have made works when I compile it in Netbeans, but when I create a Jar file it does not work. I receive a pop up message in windows ?could not find the main class program will terminate? when I execute the jar file.
The second problem I have is that I need to compare the strings generated by the "numbers" and "TIP" and if the numbers is not identical the numbers in the ?Center? JPanel should be highlighted as red.
If anyone would like to clean up the code I would be pleased. I have copied quite a lot from anyone because of my one lack of knowledge.

HOW TO SHOW JLABEL IN JDIALOG WHILE MAIN CLASS IS SLEEPING? (CODE EDITED)

I have done a code below and it is working but the only problem is when the main program start to sleep by use Thread.sleep(10000) for 10 secs and it will prompt out a JDialog contain JLabel inside it with message "Please wait.... program is sleeping.". And when the thread ends the JDialog will auto disappear and it back to the main program.
I am using TimerTask to run the JDialog while the main class is sleeping.
The problem is:
When the JDialog appear, it doesn't show the component so I only be able to view the JDialog window without contain any component. I already use container to add the component into JDialog but it still doesn't show. I only be able to see the JDialog window contain empty component when the main window is sleeping.
How to make the components also appear in the JDialog when the main program is sleeping?
Below is the code pls have a try:
public class testThread extends JFrame
public static void main(String args[])
new testThread();
public testThread()
* other code not related is here
// WHEN USER PRESS startThreadBtn it will make the application sleep for 15 secs and pop out JDialog window contain JLabel msg wrote "Please wait... program is sleeping"
JButton startThreadBtn = new JButton("Start Thread");
startThreadBtn.addActionListener
( new ActionListener()
public void actionPerformed(ActionEvent e)
try{
doTask a = new doTask();
java.util.Timer thisTimer = new java.util.Timer();
thisTimer.schedule(a, 0); // when this code executed, will pop out a JDialog containing JLabel message --> refer to class doTask
Thread.sleep(10000);
a.terminate()
thisTimer.cancel();
catch(InterruptedException ie)
ie.printStackTrace();
public class doTask extends TimerTask
JDialog infoDialog;
public void run()
infoDialog = new JDialog(true);
infoDialog.setTitle("Please Wait!!!");
Container c = infoDialog.getContentPane();
c.setLayout(new BorderLayout());
JLabel infoLbl = new JLabel("Please Wait... Program is sleeping!!!", JLabel.CENTER);
c.add(infoLbl, BorderLayout.CENTER);
infoDialog.setVisible(true);
public void terminate()
infoDialog.setVisible(false);
infoDialog.dispose();
Why I can not show the JLabel inside the JDialog? The JDialog window is opened but it contain empty component.
PLEASE HELP ME .... THIS IS VERY URGENT

I have the complete code and it is working. I can posted it here but it will be longer thats the reason why i shortened the code in here and displaying the important information.
The problem is the JDialog only will display the JLabel after the thread woke up. Thats mean it is too late for me to display the information. I need the JLabel containing the information to be displayed when the thread is sleeping....
Below is the complete code:
you can have a try to recompile it and u will understand what i mean. It is working and the only problem is JLabel component did not displayed in the JDialog.
Just copy the whole code into the txt file and save as testThread.java and recompile it. Inside the code has one inner class extends TimerTask call "doTask"

How to use an instance instead of the class itself

I am building a program but have a problem.
My program uses a controller class which instantiates a World-class. In the world class has a Vector I make a Vector in which I place all the elements in the world. (I also made an Element class from which all the objects that I put into this Vector extend.)
Everything except for some methods in the controller class are declared public. I might need to use static, but I do not know how.
// CONSTRUCTOR CONTROLLER CLASS
world = new World (); // instantiate one and only one world
world.newElement (new Beamer ("beamer", 20. , 20.)); // use a selfwritten method to add a "Star Trek"-like
                          // beamer to the world. I give it a name and position.
world.newElement (new Avatar ("avt", "beamer")); // add an avatar which is "beamed up". so what I do is that I use the beamer for the beginposition of the avatar. However, and this is my problem, in the constructor of Avatar (see below) i need the beamer in world, but my compiler cant find world. I probably need to import my World or controller class, but even then: I do not understand how to use an instance (world is an instance. I cant use the World-class as the class does not contain the beamer element)
public class Avatar extends Element {
     public Avatar (String n, String beamer){
          name = n;
          posx = world.named("beamer").getPosx; // the selfwritten method named finds the
            // element in the Vector that goes with the name. Any ideas to make this code better are welcome too.
          posy = world.named("beamer").getPosy;
} Any ideas on how to solve this (common) problem in good coding are most welcome.

I think you are best off if you use static methods and static fields only in your World class. That way you don't have to instantiate it and everyone has access to its methods. This would be then completely analogous to how you access methods and fields of the well-known class System (e.g. when you use System.out.println). This also has the advantage that you are guaranteed to have only one copy of the World.
Here is an example of how your World class, Avatar class and main code would look like.
Main code: (note the use of capital W in the name World, referring to class rather than instance).
// no need to instantiate World, as we call its static methods only
World.newElement (new Beamer ("beamer", 20. , 20.));
World.newElement (new Avatar ("avt", "beamer")); // add an avatar which is "beamed up". World class: (note the static keyword in front of the vector and the methods)
public class World {
private static Vector v;       // static field, only one copy of it ever exists
public static void newElement(Element e)   // static method, can call without instantiating world
     v.addElement(e);
public static Element named(String n) // use to look up elements
     ... some code which goes through v and finds element named "n" ...
     ... return reference to that element ...
}and finally the Avatar: (again note the use of reference to World as a class rather than instance)
public class Avatar extends Element {
     public Avatar (String n, String beamer){
          name = n;
          posx = World.named("beamer").getPosx;
          posy = World.named("beamer").getPosy;
} The above example is how I would implement it when you don't actually need instances of the World class.

Determine a string from main class in an outside class

Hello there,
This might be stupid question but I cant think, I am so very tired. Okay here is the question, is there any way we could see or the get the value of a string(just a string which is set in main class'A', its already set, we cannot make it static r anything like that)in a method outside that main class, probably in a method 'x' in class'C'.
Thanks
potti

Yes, you can, in many ways, or else Java would be moot. Excluding the static way of doing it, which by the way is evil, your class C can make an instance of class A and then access it either as a public field or as the value returned by a public method. You can also use inheritance, but it's pointless in this case, inheritance is meant to abstract, extend functionality, and prevent having to rewrite code. It's not meant for accessing fields. And by the way, inheritance, too, is evil.
This is one way to do it.
class A {
     public String s = "great balls of fire";
public class C {
     public static void main(String[] args) {
          A myInstance = new A();
          String s = myInstance.s;
          System.out.println(s);
}This is the preferred way to do it, as it encapsulates the String. The idea of encapsulation is to access fields by a method instead of directly since interfaces are less likely to change than an object's data and in the case that the object's data does change and the interface does not, the changes will remain local.
class A {
     private String s = "great balls of fire";
     public String getS() { return s; }
public class C {
     public static void main(String[] args) {
          A a = new A();
          String s = a.getS();
          System.out.println(s);
}

How can I call a method for all instances of a certain class?

Hi,
I have created a snake java applet, which you can play here [http://users.telenet.be/javagames/|http://users.telenet.be/javagames/].
But now I want to make this into a multi-player game (with two or more snakes etc..).
In my main class you can find methods like these:
snake.move();
snake.drawSnake();Now if I just alter my main class and make a second instance of the class snake and change my methods to this,
snake.move();
snake2.move();
snake.drawSnake();
snake2.drawSnake();my game almost works perfectly, I'll have to make some minor changes though.
But my question is, is there a better way of doing this. Instead of duplicating all the code, how can I make the methods immediately work for both snakes, instead of calling it twice?
All suggestions are welcome!
Thanks in advance.
Lennart

If there was something common to all snake instances then you could declare that variable static.
Note: I don't want to confuse you here. A static variable can have a value apart from any instances at all. Instances can view static variables but a static method or inner class, for example, cannot view instance variables.
More generally, I would think you would want to treat each snake as an automaton with its own behavior. There must be some class such as Game or Board or whatever that has, as suggested, either an array or collection of snakes. Iterate over each snake, ask it to perform some computation for the game and then draw itself.

Creating a new instance of a member class?

I'm writting a serialization library for a college project and I have a problem with deserializing an object which class contains a member class. A rough example:
class Outer{
     class Member{
          double d =0;
     public Member member =new Member();
}Most basically I tried to get a new instance of the Member class in order to get the double field, change it's value, then use that new instance as a field of an object of the Outer class.
Field f = Outer.class.getDeclaredField("member");
f.setAccessible(true);
f.getClass().newInstance(); Both this and the Constructor method throw an exception:
Exception in thread "main" java.lang.InstantiationException: java.lang.reflect.Fieldpointing at the line with newInstance().
Is there anything I can do to create an object of a member class? And if not then taking into account that I have to deserialize the Outer object from an XML file what could be the alternative?

The error message already gives you a hint that it's not class Outer.Member you're instantiating there (review the API docs)...
import java.lang.reflect.*;
public class Outer{
public static void main(final String[] args) {
    final Field f = Outer.class.getDeclaredField("member");
    f.setAccessible(true);
    final Constructor ctor =
            f.getType().getDeclaredConstructor(new Class[] { Outer.class });
    final Object outer = new Outer();
    final Object member = ctor.newInstance(new Object[] { outer });
    // set member.d
    f.set(outer, member);
class Member{
    double d =0;
public Member member =new Member();
}

Runnable JAR, Main-Class, Class-Path and INDEX.LST

Some funky finding, don't know whether this is a bug or a feature...
I'm using
java version "1.4.2_06"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_06-b03)
Java HotSpot(TM) Client VM (build 1.4.2_06-b03, mixed mode)
I observed follwing weired behaviour:
If you have a JAR packed with your classes and define in the Manifest a Main-Class and a Class-path pointing to JARs in the same directory than the main JAR, example:
Manifest-Version: 1.0
Ant-Version: Apache Ant 1.6.2
Created-By: 1.4.2_06-b03 (Sun Microsystems Inc.)
Main-Class: main.Main
Class-Path: activation.jar axis.jar commons-discovery.jar
commons-logging.jar jaxrpc.jar log4j-1.2.8.jar mail.jar saaj.jar wsd
l4j.jar junit.jarTHEN you should NOT have a META-INF/INDEX.LST file. This file is created for instance by ant jar when setting attribute index="true". Itt complies to the JAR standard and is used to find classes faster.
If you have such a file then none of the classes of the "Class-Path" JARs will be found. At least that was true for me...
Hope, I haven't bothered you with something commonly knwown. Just wanted to let you know, to avoid fighting againt JARs like I did for the last 3 hours..damn.
Cheers,
Peter

Does anyone know if having a Class-Path in the manifest would ignore the system environment variable CLASSPATH?
I'm seeing this in my set-up. I have an external jar file that can be seen if copied to <jre dir>/lib/ext, but when it's in another dir with the CLASSPATH pointing to it can't be found.
My applet uses a number of jar files and I reference them in the manifest using the Class-Path entry. Does this supercede the environment variable??

Reflection: get an instance of a internal class by default constructor

Hi there
first the structure (reduced):
public class ConvertionFactors { //singelton
private HashMap<String,Class> factors = new HashMap<String,Class>();
private class M_TO_FT implements DataFilter{
public double convert(double value) {
return value*M_IN_FT;
public DataFilter getFilter(String from, String to)
String name = from.toUpperCase()+convertionMethodNameSeparator+to.toUpperCase();
Class c = factors.get(name); //retrieve the class
Object o = c.newInstance(); //generate a instance.... not working
return (DataFilter)o;
The problem i want an instance of the internal class without defining a construktor like
public M_TO_FT(){} because there are many classes like this one :-(
(that was already working with a constructor that wants an instance of the container class.... thats what i am missing in the call c.newInstance() which uses the default constructor (i gues))
i want something like
new M_TO_FT() ; just the reflection version of it which calls the default constructor
thanks for help

well i get a Exception like this:

     at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.main(RemoteTestRunner.java:186)
i think because i never told the method which is the containing class for this internal class. if i defina a constructor in the inner class it always needs a instance of the containter. by calling c.newInstance() there is no relation to the container class and because the inner class cant exist without the outer class it may not be constructed.
It is possible to get an instance with "new FT_TO_M();" (the traditional way) with the default constructor but jet i have not found a way to get a instance of a inner class with reflection without defining a constructor.

Sorry, I can't help but think that this is one of the more foolish questions I've read in a while.
The pattern Singleton means "I only want one of these in a single JVM". If you want multiple instances, or even a restricted number of instances, then rewrite the class (something like this):
public class LimitedEdition
    public static final int MAX_EDITIONS = 3;
    private static int numEditions;
    public static void main(String [] args)
        try
            if (args.length > 0)

The dreaded "could not find the Main Class, Program will exit", how?

Hello all,
I am trying to run my .jar file and I get this error message.
I want to mention I googled and searched for it, without success: There is so many different explanations!
I tried this:
Adding some lines in a manifest.fm file...
Manifest-Version: 1.0
Ant-Version: Apache Ant 1.7.0
Created-By: 10.0-b19 (Sun Microsystems Inc.)
X-COMMENT: Main-Class will be added automatically by build
I have Netbeans 5.5.
Also I noticed my "build.xml" file is empty" and my "manifest.fm" nearly empty. I have also added "project, main class" in the options...
Here is my "build":
{code}<?xml version="1.0" encoding="UTF-8"?>



<project name="BetaCourseworkJava3d_Final" default="default" basedir=".">

my Manifest:

Thank you very much!
I cant believe this little comment has been so helpful!
But yes it is:
I explain, despite my efforts to find, googled it, forums, faqs, etc...
no where it mentionned the manifest.fm file is... INSIDE the .jar!
Your comment "a zip" made me attempt to open it with winrar, and I found a manifest.fm file inside!
So far I was editing the one at the "source" of my project and rebuilding it with netbeans.
I am going to try that now.
Actually.... :( no its mentionning my main class!
Manifest-Version: 1.0
Ant-Version: Apache Ant 1.7.0
Created-By: 10.0-b19 (Sun Microsystems Inc.)
Main-class: courseworkjava3d.Simple3D
Class-Path:
X-COMMENT: Main-Class will be added automatically by buildWell I have no problems uploading you the .jar, it is for a coursework it is not a private project or whatever:
http://www.uploading.com/files/CM2LKWYU/BetaCourseworkJava3d_Final.jar.html
Oh and I felt on your comment "dont ask us" as if I was suppose to know... i'm a beginner, I did not know that! And I tried to give you so many infos so you dont lose your time if you want to help, especially as after my own research I found many, many results for this "main class" and I tried a few solutions!

How can I assign image file name from Main() class

I am trying to create library class which will be accessed and used by different applications (with different image files to be assigned). So, what image file to call should be determined by and in the Main class.
Here is the Main class
import org.me.lib.MyJNIWindowClass;
public class Main {
public Main() {
public static void main(String[] args) {
MyJNIWindowClass mw = new MyJNIWindowClass();
mw.s = "clock.gif";
And here is the library class
package org.me.lib;
public class MyJNIWindowClass {
public String s;
ImageIcon image = new ImageIcon("C:/Documents and Settings/Administrator/Desktop/" + s);
public MyJNIWindowClass() {
JLabel jl = new JLabel(image);
JFrame jf = new JFrame();
jf.add(jl);
jf.setVisible(true);
jf.pack();
I do understand that when I am making reference from main() method to MyJNIWindowClass() s first initialized to null and that is why clock could not be seen but how can I assign image file name from Main() class for library class without creating reference to Main() from MyJNIWindowClass()? As I said, I want this library class being accessed from different applications (means different Main() classes).
Thank you.

Your problem is one of timing. Consider this simple example.
public class Example {
    public String s;
    private String message = "Hello, " + s;
    public String toString() {
        return message;
    public static void main(String[] args) {
        Example ex = new Example();
        ex.s = "world";
        System.out.println(ex.toString());
}When this code is executed, the following happens in order:
1. new Example() is executed, causing an object to constructed. In particular:
2. field s is given value null (since no value is explicitly assigned.
3. field message is given value "Hello, null"
4. Back in method main, field s is now given value "world", but that
doesn't change message.
5. Finally, "Hello, null" is output.
The following fixes the above example:
public class Example {
    private String message;
    public Example(String name) {
        message = "Hello, " + name;
    public String toString() {
        return message;
    public static void main(String[] args) {
        Example ex = new Example("world");
        System.out.println(ex.toString());
}

How to run 1 or more main classes in a jar?

Hi there,
I have 2 or more main classes in a java project. How do I create more than one application entry point in my MANIFEST.INF? I create my jar file from my java project using Eclipse, and it asked me to "Select the class of the application entry point". I was only able to select one main class.
I noticed the MANIFEST.INF file that eclipse generated looks like:
Manifest-Version: 1.0
Main-Class: Automobile
When I tried to run my other classes not specify in the MANIFEST.INF it failed and only look for the Automobile class:
java -jar /tmp/Auto.jar TestMe

Your app. can have as many entry points as you like, as atmguy demonstrated. But you can only specify one in the manifest,which - if you think about it - makes perfect sense. How is the machine to determine - from you clicking on the jar - which entry point you meant to invoke?

How can i execute Spaces API in java main class?

Hi
I am able to execute Spaces API through portal application. However if i try to execute it in java main class, its throwing an exception
"SEVERE: java.io.FileNotFoundException: .\config\jps-config.xml (The system cannot find the path specified)"
oracle.wsm.common.sdk.WSMException: WSM-00145 : Keystore location or path can not be null or empty; it must be configured through JPS configuration or policy configuration override.
How can i set this path, so that i can execute Spaces API from java main class.
Need this main class to configure in cron job, to schedule a task.
Regards
Raj

Hi Daniel
Currently i have implemented create functionality in my portal application using Spaces API, which is working fine. Now the requirement is, i need to implement a "Cron Job" to schedule a task, which will execute to create space(for example once in a week). Cron job will execute only the main method. So I have created java main class, in which I have used Spaces API to perform create space operation. Then it was giving exception.
Later I understood the reason, as I am executing the Space API with a simple JSE client, its failing since a simple java program has no idea of default-keystore.jks, jps-config.xml, Security Policy. Hence i have included those details in main class. Now I am getting new error,
SEVERE: WSM-06303 The method "registerListener" was not called with required permission "oracle.wsm.policyaccess"
For your reference i have attached the code below, please help. How can i use Spaces API in java main method(i mean public static void main(String[] args) by giving all required information.
    public static void main(String[] args) throws InstantiationException,
                                                  GroupSpaceWSException,

        GroupSpaceWSContext context = new GroupSpaceWSContext();
        FactoryFinder.init(null);
        context.setEndPoint("http://10.161.226.30/webcenter/SpacesWebService");
        context.setSamlIssuerName("www.oracle.com");
        context.setRecipientKeyAlias("orakey");

        systemProps.put("javax.net.ssl.keyStorePassword", "Test12");
        System.setProperties(systemProps);
        GroupSpaceWSClient groupSpaceWSClient;
        try {
            groupSpaceWSClient = new GroupSpaceWSClient(context);
            System.out.println("URL: " +
                               groupSpaceWSClient.getWebCenterSpacesURL());
            //delete the Space
            List<String> groupSpaces = groupSpaceWSClient.getGroupSpaces(null);
            System.out.println("GroupSpaces:: " + groupSpaces.size());
        } catch (Exception e) {
