Com.mysql.jdbc.exceptions.jdbc4.CommunicationsException: Communications link failure

mdea · Junho 14, 2010, 2:56pm

Ola, boa tarde amigos do forum.
Bom o problema e’ o seguinte…
Tenho uma aplicativo(Desktop/swing) em desenvolvimento, uso netbeans 6.8 / Debian squeeze e open-jdk6/open-jre6, tudo rodava norma, consultas, cadastros, enfim todo acesso ao banco fluia sem problema, mas tentei utilizar o sun-jdk/sun-jre no lugar do open-*, ambos disponiveis nos repositorios do debian, mas quando tento executar sobre esta plataforma obtenho o seguinte erro:

Amigo! Na época acabei voltando para o ubuntu e o problema não aconteceu mais!

marciofermino · Fevereiro 26, 2014, 9:00am

entao, estou com ubuntu…

os sistemas estão até rodando, lógico gerando logs e mais logs de erro,

agora, tenho uma aplicação que deveria abrir um relatório, que n?ao esta abrindo,
até pensei que por causa desses erros o relatório não abria.

Ou seja, tenhos 2 problemas

1 os logs
2 o relatório que não abre de forma alguma

o relatório só abre dentro do eclipse !
