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 …

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 Rafael

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 Eu fiz pra você desta vez

Onde estão as classes do JAVA?

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)
