ClassNotFound Exception log4j only when running exported executable jar on cmd

Question

I'm successfully running a Java console based program inside eclipse. But when I export external jar it throws me ClassNotFound Exception for class log4j. Its working perfectly inside eclipse, but when I execute exported jar with java -jar filename.jar it gives me error

I have also added the external jar of log4j in my eclipse project

And as well as to my build path, but still no result

Answer 1

Can you check if you have log4j dependencies in your exported jar. Because you are adding jars in a Build Path it might be not present in exported jar.

Here you can find how to include external dependencies in your exported jar.
