Bom dia pessoal, estou precisando de um calendário simples, onde eu possa selecionar o dia, mês e ano. Não encontrei nada no java. Alguem pode me ajudar ?
Bom dia a todos.
Fiz uma aplicação agenda e resolvi fazer o meu próprio calendário, segue ai o código:

}Aqui é a classe Render que pinta o JTable.

O problema nem é esse. Em um look and feel agradável ele fica muito melhor que aqueles screenshots no site. Acontece que ele está descontinuado desde 2005. Prefira o JCalendar mesmo.
Opa. Obrigado pessoal estou utilizando o jcalendar mesmo.
