Estou com problema no meu programa que contem um frame e um splitpanel.do lado esquerdo um jTree com duas opções.A segunda opção é um painel que contem um formulario para criação de um report com JasperReport.Qdo “rodo” o programa de dentro do Eclipse tudo fui normalmente,porém qdo gero o .jar ou tento rodar ele via prompt de comando ele retorna o seguinte erro: Exception in thread “AWT-EventQueue-0” java.lang.NoClassDefFoundError: net/sf/ja
