Prezados Colegas,
Estou tentado aprendar a utilizar taglibs mas estou com problemas:
Quando eu rodo o jsp que chama a tag ele me da erro no parse do XML falando que a tag <tag> não suporta <tagClass> … já chequei o tld é parece que está ok… será que alguém pode me dar uma ajudinha?
Desde já… valeu hein…
