Can't find main class - program will end

Dear forum readers,
Recently upgraded from Win2k pro to XP pro .. installation ran to conclusion w/ no fatal errors BUT upon booting new system I now receive an error message "Java Virtual Machine Launcher can't find main class, program will end" .. I am not aware that this error is causing any problems BUT it is annoying and I'd like to be able to fix the problem so I don't have to close the error message at each startup .. please help!
Thanks in advance, Larry

Try this
java -XbootClasspath/a -jar <<Prog name>>
I think you are trying in windows XP.
Also you need to modify if there are any other jars to be reference. For eg if a.jar is also required for this try as below
java -XbootClasspath/a:a.jar -jar <<Prog name>>

Jar file error: could not find main class. program will exit

I have created a jar file using following command
jar cfm MyProj.jar Manifest.txt richa\*.class
and I have included main class header in the Manifest.txt. The executable jar file is created but when I double click on it, it prompts an error Could not find the main class. program will exit.
Please help. Its urgent..
Thanks in advance

This simply state that jvm was unable to fine Main Class file.
I hope you have configured manifest file including your main file information and class path used by the project with proper package hierarchy,
as described in article

Error msg Could not find the main class.Program will exit. in jar execution

Hello,
I have created a jar so that I can used it in the webapp.
but when I click on it it says "Could not find the main class.Program will exit."
I searched a lot in the net and found that it has to do with the manifest file.
I even updated the manifest file using the command "jar umf main.txt filefolderupload.jar" with the class name mention along with the package heirarchy.
(pakage heirarchy in /,\ and .)
I am using JDK 1.5 . and have Updated JRE 1.6.
Also tried with extending the class with JApplet, but in vain.
Kindly help me in the above mention issue.

This post hints at a number of misunderstandings on your part, and raises a couple of important questions.
Note that this 'simple question' has a complicated answer. Given the complexity of it, it might pay to add Dukes to it, ..a lot of Dukes.
The important questions are.
1) Does this file/directory uploader need to provide the end-user with a file dialog in which they can choose a local directory to upload, or will a multi-file chooser do?
2) Does this uploader need to upload to foreign sites, or does it upload back to its own server?
Looking at this table I prepared to describe the [uploader/local file access|http://pscode.org/test/uploader/fileuploader.html] possibilities, if the answers to the questions are 'multi-file chooser will do' and 'home site only', the best option is a sandboxed app. launched using webstart (JNLP) - option 5. If either of those questions go the other way, option 6 (digitally signed with extended permissions) is needed.

Java Virtual Machine Launcher could not find the main class - program will

I have installed J2SE and followed all the instructions but upon restarting the PC I get a dialogue box with the messege Java Virtual Machine Launcher could not find the main class - program will exit.
I have tried multiple times un-installing and re-intalling this but i still get the messege when i restart windows.
Can anyone offer any suggestions as to what i may be doing wrong.
When I do the verify installation I get the congtratulations you have the latest Java Installed.
Help

Something is being automatically started when the pc starts. Assuming Windows, to see what it is, learn to use the msconfig program:

Apparently, whatever it is, it's not correctly configured.

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.

Installing 10g on Windows XP machine JVM launcher "Can't find main class"

I am trying to install 10g Release 2 on a Windows XP machine. I downloaded the zip from the OTN. Unzipped the file. No problems. Tried to run the OUI, it opened up a shell and said to wait. The shell closed and a message frome the JVM Launcher displayed "Can't find main class. Program will exit." I have seen several people on this and other discussion boards having this problem, but have yet to get a solution. Please help.

What's the value of CLASSPATH environment variable? Possibly a non-oracle application has set this variable and the installer catches it. If there is such a variable, comment it out and try again.

Can not find Main Class - Can't Run Application

I have at this for a while and it is drivng me crazy... I have an application that I want execute in a bat file. I have checked the runtime environment by executing java and javaw, both which give option on error messages. I have set the classpath to point too the class subdirectory. Here it is.., Every time I execute the bath file or execute the javaw command, I get the "Can not find main class" message.
I am using XP ...
Help please...
Thanks for all your help.

when you set the classpath I presume you mean that your running java or javaw as:
javaw.exe -cp %classpath%;.;c:\library\myfiles com.mycomp.myapp.MainClassIf your using a jar then you must specify the jar in the class path.
Don't presume it will find the jar. Other than that, you will have
to provide more details.

CAN NOT FIND MAIN CLASS

Why after i have unzipped and edited the classes in the jar file and zipped them together again, it gives me the message "CAN NOT FIND MAIN CLASS"?
This is after i have edited any class in the .jar zip.I did not edit the Manifest text file,can someone who has experienced this problem show me how to overcome it.
Thank you.

i think you have to read the "java tutorial on Jar files".
i guess after you have exracted the .jar file then you've edited the ".class"(i dont know how you did it) but i think you mean ".java" you should create another .jar file to be able to reflect the changes you have made, then set the main-class attribute of the newly created .jar file.

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...

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":

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!

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!

Problem with message: Could not find the main class Program will exit

I don't get why this isn't working. Any help is appreciated.
//Code start
public class hello{
public hello(){
public static void main( String args[] ){
System.out.println("Hello");
//Code end
I compile it as so:
javac hello.javaIt compiles fine and I now have hello.class in my current directory, but when I type the following:
java helloI get this:
Exception in thread "main" java.lang.NoClassDefFoundError: hello

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.

Brandon

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.)

Jar file could not find main class.. I cant see why?

I have read loads of tutorials on this and it should be very straight forward but i STILL cant make a working jar file of my program.. please see if you can see anything wrong with what im doing..
my program is one .java file that compiles perfectly, and is runnable both through eclipse and by using the command prompt.. i made a jar file using both eclipse and the command prompt, and neither worked.. every time i run it by double clicking it i get the error "could not find main class, program will exit". here is the contents of my jar:
CorePackage\IPEmailer.class
CorePackage\IPEmailer$1.class
CorePackage\IPEmailer$SMTPAuthenticator.class
META-INF\MANIFEST.MF
the MANIFEST.MF file contains:
Manifest-Version: 1.0
Class-path: .
Created-By: 1.6.0_02 (Sun Microsystems Inc.)
Main-Class: CorePackage.IPEmailer
(yes there is a blank line at the end)
the class mentioned in 'Main-Class' has a main method that looks like this:
public static void main(String[] args) {
    // TODO Auto-generated method stub
    new IPEmailer();
}the program uses 2 external jar files:
activation.jar
mail.jar
and reads a file called:
ipemailer.ini
and writes a file called:
ip.txt
the program has no GUI and is intended to run 'silently' in the background
please help me understand what is wrong with this

package CorePackage;
import javax.mail.*;
import javax.mail.Authenticator;
import javax.mail.PasswordAuthentication;
import javax.mail.internet.*;

          new IPEmailer();
     public IPEmailer(){
                     ..........etccould the problem be that the class is a thread? i cant see why it would be, but ive never made a jar where the main class also 'implements runnable'
