Nunca sei se coloco minha dúvida no Java Básico ou no Java Avançado.
É o seguinte:
Fiz uma aplicação que solicita informações de um serlet no servidor. Esse servlet devolve um arquivo XML, que a aplicação cliente vai ler e deserializar usando a API XStream.
A aplicação funcionou normal no computador cliente, mas quando eu usei Java Web Start para disponibilizar a aplicação deu um AccessControlException:

No código da minha aplicação a Exceção foi na seguinte linha:
XStream xstream = new XStream();
O que pode ser?
Será que eu preciso de assinar o jar??? A assinatura não é necessária somente para acessar recursos da máquina que está rodando o aplicativo? Eu não estou acessando arquivo nenhum.
Obrigado.
