Srs, boa noite!
Eu estou tentando realizar uma passagem de parâmetro via URL com JSF. Tenho duas páginas são elas,
formBonus, responsável por passar os dados via URL. dadosBonus, responsável por pegar as informações da URL e, efetuar a chamada para minha classe controle que contém um método que efetua um calculo.
O erro que está sendo apresentado é " Tag Library supports namespace: http://java.sun.com/jsf/core". Eu fiz uma busca na web e achei um novo pacote para essa tag: "xmlns:f="http://xmlns.jcp.org/jsf/core", mas se eu uso esse pacote um erro de nullPointerException é apresentado no meu método "calcula".
Segue meu fonte, junto com as configurações do meu arquivo xml e console com as chamadas no servidor. Obrigado.
