error in the las email :
1- getting the collection from UF, add the city into the collection and
setting the collection back to the UF (setMunicipios).
municipio = CadastroEJBGetter.getMunicipioHome().create();
municipio.setNome("Curitiba");
municipio.setSigla("CWB");
Collection c= uf.getMunicipios()
c.add(municipio);
-> uf.setMunicipios(uf.getMunicipios());
the right is : uf.setMunicipios(c);
