Help with compile

Hi
I am using netbeans 6.8, I build my program and I get the . JAR File.
My problem is that when I try to run my program from the command line I get this message:

Quote:

C:\Users\comm433>java -jar "E:\java projects\PlayingAudio\LSB1\dist\LSB1.jar"
Exception in thread "main" java.lang.NoClassDefFoundError: lsb1/Main
Caused by: java.lang.ClassNotFoundException: lsb1.Main
at java.net.URLClassLoader$1.run(Unknown Source)
at java.security.AccessController.doPrivileged(Native Method)
at java.net.URLClassLoader.findClass(Unknown Source)
at java.lang.ClassLoader.loadClass(Unknown Source)
at sun.misc.Launcher$AppClassLoader.loadClass(Unknown Source)
at java.lang.ClassLoader.loadClass(Unknown Source)
at java.lang.ClassLoader.loadClassInternal(Unknown Source)
Could not find the main class: lsb1.Main. Program will exit.

any suggestions

Best Regards.

When you build the package, did you define the main class in your project?

The question was, did you DEFINE the main class -- not whether you found it.

Thank you guys for help, I checked it again and defined the main class and it is running from the command line now.
I have another question ( I donot have much experience with java) the program uses .bin files to save and load data the problem is that when I run jar project I get error messages regarding the existance of the .bin files, the question is where to put them?

Regards.

Can you see the path used in the java program when it tries to read the .bin file?
Put the files there.

Well thank you Norm, I tried the URL Method for locating the files and it worked.

Thank you again.

Yeah. If you have more than one main class in your project, when you build it on NetBeans you must define which is the main from the project properties. Even when you run it you have to do that, at that time NetBeans alert you to select the main. But not in build time.
