Arquivo Jar Não funciona com quando é executado pelo Eclipse

Pessoal, estou seguindo uma apostila que tem um programa lá de exemplo que lê um arquivo XML e coloca trata o resultado e coloca em uma JTable. Esse arquivo XML é o usuário que escolhe usando uma JFileChooser.

O que acontece é o seguinte:

Quando executo o programa diretamente pelo eclipse funciona perfeitamente, carrega os valores certinho e preenche a JTable, mas quando export o arquivo .jar e executo ele roda tranquilo, mas quando escolho o XML ele não preenche a JTable. Para ler o XML eu estou usando uma classe externa a XStream. Tava pensando aqui que poderia ser classpath para essa biblioteca externa, depois descartei a possibilidade por ela estar rodando normal no eclipse. Mas é possível que precise coonfigurar a classpath em outro lugar??

Será que alguém tem alguma idéia do que possa ser o problema??

Eu crio o jar usando o Eclipse. Pra executar eu tava dando dois cliques em cima.

Executando pelo prompt ocorre o mesmo problema. Mas pude ver o erro que acontece quando seleciono o XML. Parece que ele realmente não está achando a classe que eu uso pra ler o XML.

Segue como eu executei o jar e o erro que aparece quando seleciono o XML:
