Linking external jar when starting java -jar problem

Question

Good day!
A have a little program:
import org.apache.log4j.Logger;
public class CMDClient {
     static Logger log;
     public static void main(String args[]) throws Exception {
          log.info("test");
          System.exit(1);
}I created a test.jar file, containing only this test class. When I start it by java -jar test.jar it cannot find linked (through import) Log4j library. Is there a way to link external jar to "jared" application?

There's a Class-Path attribute in the manifest.
