Olá pessoal,
estou começando no JBPM. Fiz alguns exemplos simples, e tudo funcionou (com muita dificuldade).
Estou tentando fazer com que a aplicação acesse o Postgres.
Gerei o banco, apliquei os scripts, alguns scripts tive que converter HSQLDB (uma trabalheira danada).
Há um documento em PDF em inglês, semelhante a esse postado anteriormente, que explica como mudar para Postgres, porém, não funcionou.
após tentar desa forma http://wiki.jboss.org/wiki/Wiki.jsp?page=Jbpm3.2WithPostgreSQL
(tive que alterar mais coisas, mexi tanto que uma hora funcionou).
Agora conecto na base postgres, porém, recebo a seguinte mensagem de erro:
