I added the following as the first executable statement (etc) in the project:

System.out.println("Hello 1");

I then ran the project on my friend's PC using the Command Prompt and the command: java testing.jar

I received the error message:

Exception in thread "main" java.lang.NoClassDefFoundError: testing/jar

Job one when debugging is to reproduce the problem.  Where is the

I setup my PC's "Classpath" environment variable to point to the two dot jar files.

Then on my PC at the Command Prompt, with the below command I get the following error message.

java testing.jar

Error: Could not find or load the main class testing.jar.

This command tells Java to run a 'main()' method from the class 'testing.jar', 
which would reside in a class file relative to a classpath element "testing/jar.class".

This class does not exist. Therefore

Exactly so.

> Caused by: java.lang.ClassNotFoundException: testing.jar
> ...
> Could not find the main class: testing.jar.  Program will exit.

Solution:
Don't tell Java to run a nonexistent class.

You need to read the tutorial markspace linked:
> Classpath in a jarfile: 
> 
> <http://docs.oracle.com/javase/tutorial/deployment/jar/downman.html> 

Pay attention.

About this process, I have two dot jar files in my project. I guess I put both of them in the Manifest.txt file. Question 1: Do I separate these two jar file names with a comma?

That link, basically, says to use the command:

jar cfm NEW.jar Manifest.txt MyPackage/*.class

But executing that command, I get the error message:
   MyPackage\*.class : no such file or directory.

So, Question 2: What do I put in place of "MyPackage/*.class". The NetBeans build process creates the folder (C:\testing\build\classes\) which contains about 40 dot .class files.

#18685

Executing the command:

jar cfm Install_Test.jar Manifest.txt C:\testing\build\classes\testing\*.class does produce a large Install_Test.jar file, but with the below command, I get the associated error message.

java Install_Test.jar
Error: Could not find or load main class Install_Test.jar

Thanks,

[toc] | [prev] | [next] | [standalone]

#18687

There are many other classes in the testing project under another folder in C:\testing\build\classes\, but none of them have a main method. I did not mention them on the "jar cfm ..." command line.

The only main method in the testing project is in a package called testing. The testing package is in one of the two dot jar files mentioned in the Manifest.txt file.

I guess there isn't suppose to be a comma between the dot jar files mentioned in the Manifest.txt file.

Thank you,

Asked and answered upthread. Did you read the answer?

Apparently not. It is rude to disregard answers and ask the same 
question again.

Your command line is wrong. Study the docs for how to invoke the "java" command.

As stated, "java Install_Test.jar" tries to run a class called "jar" in the package "Install_Test", 
which I'm pretty sure is not what you're trying to do.

RTFM.

http://docs.oracle.com/javase/7/docs/technotes/tools/windows/java.html

in case you don't know where to look for documentation of the "java" command.

RTFM.

Know where TFM is.

Is there such a file or directory on your system? No? Then why did you specify it?

The actual folder, not the example in a tutorial. Really?

Well give that the java command is in the format:

java -classpath myprog.jar mypackage.MyClass

or:

java -jar myprog.jar

then that is not surprising.

(1) Research:

Here are notes from books. Obviously, the solution to this problem involves simply looking-up "manifest files" on the Internet.

(1) The manifest.txt (or dot mf) file:

Main-Class: ClassName

Where the ClassName is the fully qualified name of the class that contains the main method that is executed to start the application. It isn't required, but it's typical to use the extension.mf for manifest files.

For example, suppose you have an application whose main class is GuessingGame, and all the class files for the application are in the package com.lowewriter.game. First, create a manifest file named game.mf in the com\lowewriter\game directory. This file contains the following line:

Main-Class: com.lowewriter.game.GussingGame

Then, run the jar command with the options cfm, the name of the archive to create, the name of the manifest file, and the path for the class files. For example:

jar cfm game.jar com\lowewriter\game\game.mf com\loweweriter\game\*.class

Now, you can run the application directly from a command prompt by using the java comand with the -jar switch and the name of the archive file. For example:

java -jar game.jar

This command starts the JRE and executes the main method of the class specified by the manifest file in the game.jar archive file.

If your operating system is configured properly, you can also run the application by double-clicking an icon for the jar file.

(2) You can add images to a Manifest file if you want.

(3) Complex manifests can have many more entries. The manifest entries are grouped into sections. The first section in the manifest is called the main section. It applies to the whole JAR file. Subsequent entries can specify properties of named entities such as individual files, packages, or URLs. Those entries must begin with a Name entry. Sections are separated by blank lines. For example,

Manifest-Version: 1.0
lines describing this archive

Name: Woozle.class
lines describing this file

Name: com/mycompany/mypkg/
lines describing this package

To edit the manifest, place the lines that you want to add to the manifest into a text file. Then run

jar cfm JARFileName ManifestFileName ...

For example, to make a new JAR file with a manifest, run:

jar cmf MyArchive.jar manifest.mf com/mycompany/mpkg/*.class

To add items to the manifest of an existing JAR file, place the additions into a text file and use a command such as

jar ufm MyArchive.jar manifest-additions.mf

Still not the optimal way.

Based on the information provided the most likely explanation is
a defect return key on the keyboard.

:-)

But maybe there are some information that you are not giving us!

Things like the command line used, the error message etc..

It's not tricky at all if you setup the correct type of NetBeans 
project, as I already said. NetBeans will do it all for you. There's no 
need to start messing with jar's, manifests or Ant. It's very often 
easier to re-create the project as a Java Application than it is to 
"fix" a broken one.

With a NetBeans Java application all you need is the contents of the 
dist/ directory. The main project jar will have a properly constructed 
manifest to allow the jar to be executed with "java -jar project.jar". 
Dependency jar's will be in the dist/lib directory, and a Class-Path: 
entry in the manifest will include that directory. When you build the 
project NetBeans very helpfully tells you exactly how to run it:

"To run this application from the command line without Ant, try:
java -jar "/path/to/project/dist/project.jar".

All you need to distribute to anyone else is the dist/ directory. 
There's even a clue in the name.

And it's not the one you have loaded, it's the one you have set for the build target. In other words, if you are using JDK 7, you can still be targeting for example Java 5 in your project, which is useful if you have users still on Java 5 who don't want to upgrade. Right-click on the project, Properties -> Sources, way down at the bottom it says "Sources/Binary Format", that's your target (I'm using NB 7.2 btw, I seem to remember a slightly different option format in NB 6). Also, you need the JRE. The JDK is for development, your users won't normally need that. All they need is the normal runtime, the JRE. You personally can use the JDK, because it contains a JRE, but anyone else will normally just have the JRE. To run, you use java -cp <path to all needed jars> -jar <path/your jar> If you need to do fancier things than that (distribute over the internet, for example) then look into Java WebStart or consider OneJar if you are going to just copy the files around.

How do I determine the specific JRE that I need.

You can bundle it up into a jar.
