I use this method to specify my JCE provider. So I raise my hands !! But if another way to select my provider exists (except placing it at the first rank in the provider list), I can change my code
-----Message d'origine----- De : Raul Benito [mailto:[EMAIL PROTECTED] Envoyé : samedi 22 octobre 2005 14:37 À : security-dev@xml.apache.org Objet : Re: how to specify JCE provider for XML encryption This way of setting the Provider using the JCEMapper, has some bugs(it works for digesting/signing but not for crypt/decrypt). Anyway I was thinking of deprecating/removing this methods. So if more people use it please raise your hands, soon.
