Having a trouble on java.lang.NoClassDefFoundError

I have a test.jar package and a Test.java file in the same folder(it is not in my CLASSPATH).

In the .java file I import some classes that are in the .jar package.
So I go the that folder, use java -classpath test.jar Test.java to compile. Everything looks good. Then I use java Test, it gives me an error: 

Exception in thread "main" java.lang.NoClassDefFoundError:......

saying that it cannot find the classes inside the .jar file.

I move the file to Eclipse and add the jar file, it works.

just as you compiled the code using javac -classpath test.jar Test.java you should use the java command to run (add the jar file in the classpath) java -classpath test.jar Test.java

You must run the java command with the classpath too, same as the compiler.
