Pessoal,
Será que alguem pode me dá uma dica de como resolver isso?

... 6 moreeu tenho um codigo que eu rodo ele no NetBeans e não dá erro nenhum, executa. Referenciei as seguinte bibliotecas:
commons-httpclient-3.0.1.jar
commons-codec-1.4.jar
commons-codec-1.4-sources.jar
commons-codec-1.4-javadoc.jar
commons-logging-api-1.0.2.jar
Mas quando eu gero o arquivo .Jar, que foi criado seguindo essa dica, http://preclog.blogspot.com/2010/03/criando-jar-no-netbeans-sem-pasta-lib.html , para que todas as dependencias fossem criandas juntas, aparece o erro acima.
segue o codigo:
