omg i have been working on this FOREVER and none of the many suggestions worked. But first i should tell you that every single step I had huge problems but I never gave up because I have successfully configured a few years ago when I first tried to teach myself Java. Anyway, I have made many mistakes configuing the CLASSPATH so I really didn't know what to fix. After finally getting it to compile successfully (creating the class file) it still wouldn't work. Finally I tried this...and I didn't see it anywhere in this blog so I hope it helps everyone after me. In addition to what you have in the CLASSPATH (int the envir. varables)add the following without deleting anything you already have there:

.;C:J24work

instead of J24work you should enter the exact path to where you are puting you .java and .class files which is probably different from where you JDK is for some people.

I truly hope I explained this well and it helps someone.

This was really saved my problem. I changed the CLASSPATH variable to add the current directory. Which is ".", This saved me my life. Thanks for the valuable post.

I got this error in my eclipse. I found there was class file getting generated for the project. Reason was no default java builder defined for the project.Opened the .project file and added the default java builder definition. Now it works fine

Apparently it matters in which order you put the class-files when creating your jar-file. If you're using superclasses/subclasses you have to put the superclass first in the command! Like so: "jar cvmf manifest.txt myfile.jar SuperClass.class SubClass.class TestClass.class"

Thank you. This was what i was looking for.

in commandprompt go to the global path of your application:
d:\applications\myApplication\bin

execute your application
d:\applications\myApplication\bin>java -cp com.package.model.myClass

change the JAVA_HOME to
d:\applications\myApplication\bin

THIS IS A MESSAGE FOR EVERYONE WHO STILL HAVE THIS PROBLEM

I'm sure you've tried everything written in this forum. After looking for an answer at Oracle's website, I've finally found it.

WHAT YOU'VE GOT TO DO is to stand in the src folder of your proyect, NOT IN YOUR PACKAGE. then, use this syntax:

java -cp . PACKAGE.CLASS

remember, your cd must be your proyect/src and follow the syntax above.
