cannot run java file in command line that created by eclipse

Question

If I create Java file by touch command in command line, edit it using nano, compile it by javac, and then run it, all works well.

But if I use eclipse to build the project, and create file in eclipse. I can compile it using javac, but cannot run it in the command line.

it shows

Error: Could not find or load main class

why this happen? is anything wrong?

Answer 1

sounds like all about right path in which you trying to run your class. did you use packages? did you run it from bin|target|build dir? please provide commands and paths from which you trying to execute it
