Caros colegas,
Apenas para efeitos didáticos, estou tentando capturar os dados de uma entidade em minha index.jsp. Consegui capturar os dados, porém não consigo setá-los no bean.
Abaixo os códigos.

System.out.println("String: " + name.getName());
}
public void close() throws SQLException {
if (conn == null) return;
conn.close();
conn = null;
}
}
ao chamar o método deleteRow (através do link "excluir" na minha jsp) o seguinte erro surge:
SEVERE: 'java.lang.ClassCastException' when invoke action listener '#{customer.deleteRow}'
public void deleteRow (ActionEvent event){
UIParameter parameter = (UIParameter) event.getComponent().findComponent("excluir");
String name = parameter.getValue().toString();
System.out.println("String: " + name);
}
Alguma dica!?!?!?
Desde já agradeço!
