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:
C:\Documents and
Settings\user\Desktop\test>D:\JRun4\bin\jspc
Compiling: /index.jsp
java.io.FileNotFoundException: C:\Documents and

Find the implementation class of a Business object

HI Gurus,
Is there any path in SPRO from where we can find the implementation class of a BOL object?
For an example, I am working with BuilHeader. The backend table for BUL Header which will be updated while modifiyng BuilHeader is BUT000. So how can we find the back end database table name or implementation class where the table BUT000 is updated?

Hi Suchandra Bose
the flow will go like this.
1) the data in the BOL structures moved to Genil Implementation Class which is defined in the below SPRO path
CRM->CRM Cross application components->Generic Interaction Layer/Object Layer->Basic Settings in this corresponding each and every component one Genil class and its Model information in the form of tables will be maintained.
2) Take for example BP component , for BP component CL_CRM_BUIL is the Generic Interaction layer class , with in the generic interaction layer class methods (Create_objects, MODIFY_OBJECTS, GET_OBJECTS) you will find a code snippet to get the * Handler class* , this handler class will inturn get the Interaction Layer classes to reach the API ,
get object handler
      lv_cl_object =
         me->handler_factory->get_obj_handler(
                                  iv_object_name = iv_object_name ).
3) This handler method will query the table CRMC_OBJIMP_BUIL to get the relevant handler class depending on which functionality you are implementing.
Thanks & Regards

I was able to resolve this issue by performing following.
1. Go to the location where sqldeveloperW.exe is being executed from.
2. You will find a file sqldeveloper.conf in that location. Edit this file and change the value of IncludeConfFile to point to actual place. For me following were old and new values.
OLD (Wrong) : IncludeConfFile ../../jdev/bin/ide.conf
NEW (Correct) : IncludeConfFile ../../ide/bin/ide.conf
After making above change in the sqldeveloper.conf file. Save and close it. Restart SQLDeveloper. You will not get the error anymore.
Thanks

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.

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"

How Do We Find the Latest Version of a Document without its Path?

Does anyone know how to find the latest version of a document in iFS when you don't know the path of the document? I'm using a Selector to search iFS based on a search string for the object's title and am not sure how to find the latest version of the returned documents.
Thanks for any help.

If you can use the Selector to get the public object then you are in good shape. Once you have the public object recast it to a Family. The method getLatestVersion() will return the public object of the latest version.

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

Where is SearchExcel.class?Excellent question, though I think I spotted a problem with the cp supplied.
Note the documentation for -cp state (in part)
For example, if directory foo contains a.jar and b.JAR, then the class path element foo/* is expanded to a A.jar:b.JAR, except that the order of jar files is unspecified.So instead of this..
java -cp /tmp/MyJava/excelapi:/app/jdk/1.6.0_16/jre/lib:/app/jdk/1.6.0_16/lib SearchExcel..try this..
java -cp /tmp/MyJava/excelapi/*:/app/jdk/1.6.0_16/jre/lib:/app/jdk/1.6.0_16/lib SearchExcelNotes:
1) Adding the JRE classes to the classpath should not be necessary, but I left the rest of the cp unaltered to highlight the one specific difference I am suggesting.
2) When posting code, code snippets, HTML/XML or input/output, please use the code tags. The code tags help retain the indentation and formatting of the sample. To use them, select the sample text and click the CODE button.
If that still fails, tell us more specifically where the SearchExcel class is by copy/pasting the output (within code tags) of the command..
prompt>jar -tvf mysearchexcel.jarWhere, of course, you replace 'mysearchexcel.jar' with the actual Jar name it is supposed to be located in.
Edit 1:
Changed JavaDocs -> documentation.

Could not find the main class : HelloWorldApp program will exit

please help me
i downloaded and installed jdk-6u13-windows-i586-p(1) from sun.java.com
in my computer --> Advanced --> environment variables --> i had set
user variable :
variable value
java_home C:\Program Files\Java\jdk1.6.0_13\bin
System variable:
path : C:\Program Files\Java\jdk1.6.0_13\bin
after that i wrote a program
* The HelloWorldApp class implements an application that
* simply prints "Hello World!" to standard output.
class HelloWorldApp {
public static void main(String[] args) {
System.out.println("Hello World!"); // Display the string.
i saved in c:\ mywork
i compiled it with
javac HelloWorldApp.java and then
java HelloWorldApp
output / result also came
but iam unable to create jar file . when it is created it is showing
could not find the main class : HelloWorldApp program will exit

You have to specify the manifest with a special option (I think its was -M)
Otherwise the jar will create one (even if you provide it)No, the text file passed as a parameter will be incorporated in the manifest file generated by the JAR tool.
@OP: This will work:
JarTest.java
public class JarTest {
public static void main(String[] args) {
System.out.println("JarTest works!");
}manifest.txt
Main-Class: JarTest+(note there is an extra new line in the manifest.txt!)+
Now execute these commands:
javac JarTest.java
jar cfm MyJar.jar manifest.txt JarTest.class
java -jar MyJar.jar And on my machine, the string "JarTest works!" is displayed on the screen.
And if you look in the MANIFEST.MF file inside your jar file (you can use almost any zip-utility for this), you will see the following:
Manifest-Version: 1.0
Created-By: 1.6.0_0 (Sun Microsystems Inc.)
Main-Class: JarTestOr something similar.

Could not find the main class. Program will exit!

I have created many Executable Jar files before, and this one I did the same. When I run the jar file, (Clicking on it) I get the "Could not find the main class. Program will exit!" error message. When I run the jar file through DOS I get this Stack trace:

Any Ideas? I did a search on google, and looks like others have had this problem but found no answer.

There could be several reasons for getting this "Could not find main class" error message. From your stack trace it looks like the class javax/media/ControllerListener is not in your class path. Make sure your manifest file has a line like this:
Class-Path: pathToTheJarFileWithControllerListenerClass.jar otherJars.jar
This error message is also generated whenever any static initialization errors out giving the misleading error message implying that there is something wrong with the main class. Prior to starting your main class, static initialization of any static variables takes place. In my case, I was initializing a resource bundle, and forgot to include the property file in my building of the jar file. Well this failed of course and the generic error message appeared. It took many long hours to figure out it didn't have anything to do with the manifest file or the main class itself.

Could not find the main class: projectRFID.ProjectGUI. Program will exit.

Hello,
I'm quite new in Java. I have an application with GUI. When I'm using Eclipse version 3.4.0 to run the application, all it is working perfect.
But after I generate the jar from Eclipse, using the manifest file option from there and added the ProjectGUI to it, where is the main class, and try to run from the command line I receive the next error:
root@slax:~/workspace# java -jar rfid.jar
Exception in thread "main" java.lang.NoClassDefFoundError: projectRFID/ProjectGUI
Caused by: java.lang.ClassNotFoundException: projectRFID.ProjectGUI

Could not find the main class: projectRFID.ProjectGUI. Program will exit.
root@slax:~/workspace#
I run this application on a SLAX system with jdk6 update 7.
I tried to generate the jar file even from the command line using the manifest file option but I still receive the same error.
I hope somebody can help me!
Thank you!

The structure of my project in Eclipse is src/project/files.java and in jar file is src/files.java bin/class.java Dati/ and META-INF/.That's wrong. You don't need the .java files in the jar (but you can have them, if you want, they are just not used by Java).
And each .class file must be in a directory that reflects its package. So in your example ProjectGUI.class must be in the directory projectRFID/ inside the .jar file.
