Eu uso o Struts e na Action que gera o reletório eu acesso o contexto e pego o path à partir daí coloco somente a package onde está o .jasper sacow?

Algo como:

mapping.getServletContext().getRealPath();

Acho que é isso, e me retorna o caminho absoluto do diretório base da minha aplicação :wink:

Estou usando assim
String str = this.getClass().getResource(“Bean/Relatorios/teste.jasper”).getFile();
que da mesma forma me retorna o caminho absoluto
mas continua dando o mesmo erro
