PostGre + JAR

Programação Java
#1

Quando crio o arquivo Jar ele aparentemente não dá erro, mas também não funciona, ele apenas chama a tela principal e não chama o cadastro solicitado. Quando executo pelo modo Dos, dá o seguinte erro:

Já tentei mudar de lugar as pastas os arquivos do postgresql, mas não deu certo.

Obrigada

vc precisa adicionar o driver do postgres no seu classpath…

mas no manifest de seu jar vc pode adicionar ele tb…
com a propriedade “Class-Path:”

espero ter ajudado!..

Já tenho adicionado os drivers do PostGreSQL. Quando rodo o programa a partir do Eclipse ele funciona normalmente, porém qdo crio o Jar é que acontece esse problema.

Como faço para adicionar no manifest?

Obrigada

Só porque roda no Eclipse, não significa que funcionará fora dele!

Edite o arquivo manifest.mf do JAR e adicione a linha:

onde postgresql.jar é o jar do driver do postgre.

Pegue o jar do driver e coloque junto com o seu.
