Error: "Could not find the main class: Files\NetBeans"

I am working on a WorldWind mapping application but I think this issue is more of a straight Java question. I was attempting to add a web service reference by means of the NetBeans IDE. The reference compiled as it should have but then the application would not run. I deleted the reference, commented out all the code that used the web reference, basically restored all the code to how it was before trying to add the web service. The applicaiton still will not run with the message that it can't find the main class. I do, however, get a clean build. What should I do to fix this?
Here is the error: "Could not find the main class: Files\NetBeans"
thanks!

thanks!Sounds like something (a .cmd file or .bat file, perhaps) is set up to launch NetBeans with a command line like this:
java -classpath ... c:\Program Files\NetBeans ...
So since the path has embedded space(s) in it, it thinks you are wanting to run a class named "Files\NetBeans", which does not exist.
You need someone there who knows what they are doing to look into it for you.

Help Me Urgent...Error: "Could not find the main class. Program will exit."

Am using Eclipse 3.3.2
I have a project called: SWDS
Initially i have JDK1.6 installed in my system. At this time the project is running succesfully.
But when i removed(uninstalled and environment path also removed) JDK 1.6 and installed JDK 1.5 and path also given.
No changes are made in the project code.
When I Run the project SWDS then showing an alert "*Could not find the main class. Program will exit*" and then getting error messages like:

Pleez help me how to rectify this error.

The manifest file is missing from the project.
I searched the net and read about the manifest file and I saw that it is supposed to be located in META-INF/MANIFEST.MF. I suppose that means project_root/META-INF/MANIFEST.MF, right ?
I am asking this because I haven't got that much experience in Java and this is the first time I hear about a manifest file.
Does anyone have any Ideea how I add a manifest file to a project with Eclipse SDK? I searched the menus and I didn't find anithing of such sort... o
Does Eclipse have support for editing manifest files at all?

Can not start WebLogic in Eclipse. Error: "Could not find the main class."

I have installed Eclipse 2.0 and WebLogic Server 6.1. and the WebLogc plug in from GENUITEC (and jdk1.3.1_04, on Win2K Server). After I have done the configuration, the WebLogic start/stop buttons are integried into the Eclipse Toolbar, but when I click on the start button to start Weblogic, it pops up a dialog box "Java Virtual Machine Launcher" with message: "Could not find the main class. Program will exit!"
Starting WebLogc Server from the Start panel works fine.
Does any one have seen this before or have a suggestion what I should do?
Many many thanks in advance.
Huan

Weblogic must be started with a full JDK; otherwise
JSPs and dynamic EJB stubs could not be deployed. The
error message
indicates you are attempting to use a JRE. Configure
Eclipse JRE to point to a JDK. The product
documentation will help you with this process. It does not work for me. :-(
I have tried JDK 1.3.1 and 1.4.1: same result: I get a "Could not find the main class: Program will exit"

Could not find the main class error with executable jar

Hello,
I have troubles creating an executable jar file and I ran out of ideas how to solve it so I would appreciate some help.
I have created a jar file with the export function in eclipse
the Manifest.MF file contains:
Manifest-Version: 1.0
Main-Class: view.AppTennisViewI tried starting the file with a batch file which contains following code:
@echo off
javaw -classpath c:\TennisHSQLDB_GC2\tennisApp.jar
@start javaw -jar tennisApp.jar
exitthe batch file and the jar are both located in c:\TennisHSQLDB_GC2.
When i try command line I get the same result.
I also tried alternate statements such as SET CLASSPATH iso javaw -classpath and including the classpath in the manifest file but no luck. It keeps given me the error: could not find the main class. program will exit
Anyone any suggestions for my problem?

nevermind, found it.
classpath in manifest was incorrect

JAR file: could not find the main class.

I have been working with Java satisfactorily for about two years.
Installed a bigger hard disk.
Installed Windows XP.
Downloaded java.
Downloaded java jdk 1.6.0_07
Downloaded java3d 1.5.2
Downloaded Eclipse Ganymede.
A new project, a new class with an existing and working java file. It did function in eclipse.
Generated a jar file with:
Export \ JAR FILE \ select files and the destination for the Jar file .....
... next...next filled the field Main Class
This generates the jar files, which have worked before.
And now the error: could not find the main class.
Thand you for your help.

Executing a jar file means it will not read from the CLASSPATH environment variable. I learnt this the hard way a few weeks ago and I had to resort to different measures to work around it.
Your problem does sound weird, but check that the last line in your manifest file is a new line. If it's not, the manifest is not read and parsed correctly.
To test, do this: remove everything from the manifest that you don't need, except the Manifest-Version and Main-Class attributes. Make sure the last line is a new line, and see if it works.
Cheers

Could not find the main class (with every jar)

This isn't a developer question. I get the error Could not find the main class with every jar I try to open (for example the jar downloaded from https://gjar.dev.java.net/ gives the same problems - and I don't think there is something wrong with that JAR). It isn't a problem with the jar or MANIFEST because the same jar works fine on my laptop. So there is something wrong with my JRE installation, but what?
I tried to remove and reinstall the JRE 6 Update 18 but that didn't work. When I run the JAR with command line java -jar "file.jar" it works fine, but if I dubbelclick on it I get the error message (and it's irritating me).
I'm a bit desperate so I hope that someone here can help me ;)
Thanks in advanced

Could not find the main class ! exception.

hi,
I create one java project. for this I am using netbeans 5.
I try to run the project jar file stff.jar. When run using "java -jar stff.jar " , it throws error "could not find the main class. program will exit".
I am extracting this jar file, in manifest, main class is set.
i.e, in manifest, Main-Class: ems.emsFrame.
ems is my folder ,inside it main class kept.
here, emsFrame is my main class where " public static void main (String args[])" is located.
I am also, set the class path for that class folder(ems) and run.
The same error ("could not find the main class. program will exit") occured.
Why this error occured.
also,I am uninstall the jdk and reinstall .
whats my problem.
bye

yes sir.
In projects, inside it, in Libraries ,the SNMPInquisitor.jar is located.
inside that jar, snmp package is located.
but, when build and run, there is no problem sir.
Only when i try to run the stff.jar file (java -jar stff.jar), that time only the exception thrown.
when I double click that jar, it show, "could not find the main class. program will exit". But, I am adding the main class in manifest. when i open manifest.mf, it show, Main-Class: ems.emsFrame.
but, when i run jar thro' cmd window, it shows,
Exception in thread "main" java.lang.NoClassDefFoundError: snmp/SNMPGetException
at ems.emsFrame.<init>(emsFrame.java:1163)
at ems.emsFrame.<clinit>(emsFrame.java:1155).
i am still trying it.

JAR "could not find the main class"

I'm running applications under XP.
In my profile:
I have a lot of problems double clicking on a jar file.... it always gives me this error: "could not find the main class"...
In other XP profiles:
All jar files run properly!
Help me!

Is your manifest correct? Does it contain the line
Main-Class: Application
or
Main-Class: package/Application
in the main section of the manifest (case sensitive)? Can the interpreter find all the required class files?

Java Access Bridge 1.1 Could not find the main class

When I try to load Java Access Bridge 1.1 I receive the following error:
Could not find the main class. Program will exit.
Does anyone know why?

you must check with the classpath
please see that you have not repeated %classpath%
at the end of the class path like you do in win98.
similiarly with %path%
in win2000 it is automatically taken care off.

Executable JAR file: Could not find the main class.

Hello,
I have a problem with making an executable JAR file.
I have written a JAVA program that consists of five different classes of which User.java is the main class and I have saved a text document with Main-Class: User and a blank line after that.
If I try:
jar cmf MainClass.txt User.jar User.class Beheerder.class Operator.class Manager.class MaakVisueelSchema.class
it makes a executable jar file which actually works! :)
But when the Operator class trys to open the MaakVisueelSchema class the screen stays blank.
I can run MaakVisueelSchema with java MaakVisueelSchema.
So I tried to make an executable JAR that consists only of MaakVisueelSchema, the same way as I did for User:
Main-Class: MaakVisueelSchema
jar cmf MainClass.txt MaakVisueelSchema.jar MaakVisueelSchema.class
Then I get the error message:
Could not find the main class. Program will exit.
from the Java Virtual Machine Launcher.
The big difference between MaakVisueelSchema and the other classes is that MaakVisueelSchema contains a PaintComponent method and an ComponentListener. Is it possible that one of those creates the error?
Can anyone help me with this problem?
Thanks in advance!
Bye!

Yes,
I tried:
jar xvf MaakVisueelSchema.jar
and it returns:
META-INF/
META-INF/MANIFEST.MF
MaakVisueelSchema.classN/G. You need to manually create a manifest file in a text editor, have it point to your main class, and enter it in your jar command as an argument.

Could not find the main class Error

Hi all,
I think that JRun compiles something to jsp files if the jsp
folder does not contain jsp files. Is that right? I started a
server running in JRUN4. And later at some point (I don't know what
I was doing), I got this Error Dialog that said "Could not find the
main class. Program will exit." In addition, the title of that
dialog was "Java Virtual Machine Launcher". What does this message
mean? Please help me. Thank you.

Okay, I created a simple hello jsp file in the test folder.
Then I ran the command:
D:\JRun4\bin\jspc at the current directory of C:\Documents
and Settings\user\Desktop\test>
The result that I got this:

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.

When you compare objects, use ".equals()" and reserve == for comparing values.

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.
tia,
Sarwa

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.

Error: "Could not find the main class: Files\NetBeans"
