Windowlistener on a main class but listening to subclasses

hi
is it possible to have a windowlistener in a main class
but listen to jframes(opened by the following method "show()") in subclasses
theres a few reasons why i want to do it this way, rather than have each subclass with its own WindowListener
1. less code to write for each class
2. i have methods inside the Main class that i want to use such as (.setCursor)
thanks for your time:)

thanks for reply one last question
do you make reference to the subclass itself?I don't understand your question.
When you ask a question try to give as much details as possible.
The way you handle each event is up to you.

Servlet can't run,Could not find the Main class,but how ?

well i have made a simple servlet,but when i run it i get the following error.

Thanks for the very fast response,but how ?
Can you run your servlet on OC4J standalone directly, to narrow down the problem..
thanks,
-Prasad

A quick way to test would be
- Assuming you have OC4J standalone installed
- copy your servlet (HelloWorld.java) file into \default-web-app\WEB-INF\classes
- compile it
- run it using the url http://localhost:8888/servlet/HelloWorld

Executable Jar: Could not find the main class. Program will exit.

I have a jar which contins the class Main.class.
Following details are specified in the Manifest file.
Manifest-Version: 1.0
Main-Class: Main
However, when I double click the jar file, I get the error...
Could not find the main class. Program will exit.
What could be wrong?
Thanks in advance

hi,
i've got exactly the same problem: double clicking the archive ends with an error (can't find the main class) but working with the command line executes the file!??!
does anyone know a solution?
thanks

How to set main class in netbeans?

i have a class with a main method that i want to set as my main class, but i dont have the source for it. how can i set it as my main class in netbeans?
thanks!

ya i can run in from the comand prompt, Excellent.
and yeah your right it should be easy. It IS easy. You just did it.
but for the life of me i cant figure it out. What can't you figure out? How to do the same thing in NetBeans?
i dont know where else to turn.Let me suggest the NetBeans docs. I'm sure they've got something in there to tell users how to run a .class with a main() method.
Better yet, keep doing things on the command line until you're knowledgable about NetBeans and leave the IDE alone until you know Java. Two mysteries at once is too much.

Java can't find main class when manifest has certain JARs on it

I recently wrote an Ant script that builds my application and jars it up, creating a manifest in the process. The manifest specifies the main class and a classpath that mentions other jars that exist in the same directory. Everything works as expected and I am able to run the program using "java -jar abc.jar".
However, I recently started using classes in my program that come from a jar that should (according to the company I work for) reside in a central location rather than each application having its own copy. So, I changed my build script to reference those shared jars in a common location. But now when I run "java -jar abc.jar", I get a java.lang.ClassNotFoundException: com.example.Main. If I edit the jar's manifest and manually remove the new jars from the classpath, the ClassNotFoundException error goes away (although obviously that causes other problems.) Is there something about adding those new jars to the manifest classpath that would prevent Java from finding my main class? My manifest looks something like this and the last two jars (the ones with the absolute paths) are the jars that seem to be the root of the problem.

I still don't know why giving the absolute classpath entry like that would cause Java to be unable to find the jar's main class, but I did make an interesting discovery. If I give the absolute path without the drive letter, is able to find the main class again. Something like this won't work...
Class-Path: C:\software\tibco\ems\clients\java\tibjms.jarBut something like this will...
Class-Path: \software\tibco\ems\clients\java\tibjms.jarBut I'd still like to know why Java doesn't accept drive letters when running on a Windows machine. After all, what if my manifest needed to reference a jar that was on a different drive, like a network drive (since this whole problem came up as a result of shared common jars that need to exist outside of the project.)

The "-cp ." tells Java to ignore the CLASSPATH variable and just look in the current directory instead. You probably had the location of StdIn on your CLASSPATH variable.
What you need to do in this case is to add the current directory "." to your CLASSPATH variable.

[Jar Executable] Could not find the main class. Progam will exit.

Hello,
I am a French person. Excuse me for my English who is not perfect.
I seek to create an achievable "jar". I followed the instructions given in the url http://java.developpez.com/faq/java/?page=execution#creationJar, and on the site of Sun.

Salut,
It has been my experience that it is never a good idea to name your .MF file anything else other than MANIFEST.MF.
Try naming your .MF file MANIFEST.MF and rebuild your JAR.
Bon chance.

Need help with custom event from Main class to an unrelated class.

Hey guys,
I'm new to Flash and not great with OOP. I've made it pretty far with google and lurking, but I've been pulling my hair out on this problem for a day and everything I try throws an error or simply doesn't hit the listener.
I'm trying to get my Main class to send a custom event to an unrelated class called BigIcon. The rest of the code works fine, it's just the addEventListener and dispatchEvent that isn't working.
I've put in the relevant code in below. Let me know if anything else is needed to troubleshoot. Thank you!

Alright, this compiles, gives me no errors, shows my 'book' and 'flowers' icons perfectly when ran, and prints 'addEventListener' to the output window as expected. I get no errors when I press the button, 'dispatchEvent' is output (good), but the 'twitchUp' function is never called and 'EventTriggered' is never output.
How do I get the 'twitchUp' event to trigger?

Jar files and Main-Class attribute

Sorry, I know there are other topics regarding this argument but none of them helped me solving my problem.
I've tried a thousand time in every possible way, but I still can't run my application from a jar file. I've got a package called client, whose main class is called Client. The package contains a sub-package called Icons. I've put everything into a jar file and added this manifest:
Manifest version: 1.0
Name: client/
Sealed: True
Main-Class: client.Client
But it won't work. I've tried to erase the Sealed part, I've tried "Main-Class: Client" and also "client/Client", I've tried putting into the jar the client directory and I've tried omitting it, but the answer is always the same:
Failed to load main-class header etc.
Can anyone help me? Please, I'm almost desperate!
Thanks

Forwarding events from my menubar class to main class

I'm brand new to swing. I'm trying write an app, and wanted to encapsulate my JToolBar and JMenuBar items, so I made classes to handle each of them. Then from my "main" class I could just call a function and voila.
However the one obvious problem is that my "main" class doesn't know when JToolBar or JMenuBar items have actions. Those classes each handle their own event listening. I was hoping (probably through magic) that I could then forward that action to the main class somehow.
The obvious solution would be to expose the individual toolbar JButtons and JMenuItems and call addActionListener(this) on those items from the "main" class. However I'm hoping to avoid having to expose those items, probably just because I'm anal.
One idea that I've seen but seems kind of not-very-elegant was to create an item to track the state of all things, and pass that item around. Then in my individual actionPerformed() functions I could manipulate that item so that the main class could see those changes.
I imagine I'll have this same issue when I get into more complicated parts of my would-be application than just the menubar. Any help would be appreciated.

OK so I can define the new actions in my main class and then in my toolbar/menubar items I just tell them to use those main class Actions? Hopefully I have as somewhat firm a grasp on this as I think I have. I'll try that out now.

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

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?

Using main class's methods from a different class in the same file

Hi guys. Migrating from C++, hit a few snags. Hope someone can furnish a quick word of advice here.
1. The filename is test.java, so test is the main class. This code and the topic title speak for themselves:
class SomeClass
     public void SomeMethod()
          System.out.println(test.SomeOperation());
public class test
     public static void main(String args[])
          SomeClass someObject = new SomeClass();
          someObject.SomeMethod();
     public static String SomeOperation()
          return "SomeThing";
}The code works fine. What I want to know is, is there some way to use test.SomeOperation() from SomeClass without the test.?
2. No sense opening a second topic for this, so second question: Similarly, is there a good way to refer to System.out.println without the System.out.? Like the using keyword in C++.
Thanks.

SomeOperation is a static method of the test class, and it's best to call it that way so you know exactly what your code is doing here.
2. No sense opening a second topic for this, so second question: Similarly, is there a good way to refer to System.out.println without the System.out.? Like the using keyword in C++.Again, you could use static imports, but again, I don't recommend it. Myself, I use Eclipse and set up its template so that when I type sop it automatically spits out System.out.println(). Most decent IDE's have this capability.
Also, you may wish to look up Java naming conventions, since if you abide by them, it will make it easier for others to understand your code.
Much luck and welcome to this forum!
