Boa noite senhores,
Estou fazendo um fileupload com servlet usando o jakarta fileupload.
mas meu problema não é enviar o arquivo. é sim resgatar mais um parametro do meu form, eu li em alguns foruns e outrso sites. que quando o form é multpart/form-data ele nao funciona com o request.getParameter("item");,
gostaria de saber se existe alguma outra forma de recuperar esse parametro:
posto aqui meu servlet de upload, com restriçao de tamanho e de extenção e mudança de nome para a data e hora ,funcinando.
