The problem above is with jBPM 5.4 . I also tried with jBPM 5.3 and with this version I can connect to PostgreSQL database, starting jBoss creates the schema. But then I have the following error in the jbpm-console :
Caused by: java.lang.NullPointerException

With jBPM 5.4, the error was when starting jBoss :
08:19:31,030 ERROR [org.hibernate.tool.hbm2ddl.SchemaUpdate] (MSC service thread 1-1) HHH000388: Unsuccessful: create table Attachment (id bigint generated by default as identity, accessType integer, attachedAt timestamp, attachmentContentId bigint not null, contentType varchar(255), name varchar(255), attachment_size integer, attachedBy_id varchar(255), TaskData_Attachments_Id bigint, primary key (id))
08:19:31,046 ERROR [org.hibernate.tool.hbm2ddl.SchemaUpdate] (MSC service thread 1-1) ERREUR: erreur de syntaxe sur ou près de « generated »
and this is why I tried to create the schema with a sql script.
I will try a new installation from scratch with jBPM 5.4, and if it still doesn't work I will try MySQL.
