Onde estão as classes do JAVA?

Programação Java
#1

Olá,

Estou tentando rodar o MAVEN (seguindo as instruções: maven build).
Uma das mensagens de erro é a seguinte:

9: package javax.media.jai does not exist
import javax.media.jai.ParameterList;

Com esta me ocorreru que nunca encontrei o Package JAVA ou JAVAX. O que está errado aqui? Onde está a biblioteca padrão do Java?

Obrigado,

José.

O JAI eh um download a parte, e eh comum a maior parte do pessoal nao ter o mesmo. Voce tem que pegar em http://jai.dev.java.net

Obrigado pela dica. Deu tudo certo.

Estou tentando compilar um programa ( GEOTOOLS) e tenho o seguinte erro relacionado a pacotes. O erro que recebo é:

// Mensagem de erro (parcial)

Olá,

Quando vc for postar codigo, tenha do dos nossos pobres olhinhos e coloque-o entre as tags [ code] e [ /code], assim ele nao vira uma macarronada pos-modernista :wink:
