Thank you for your time, kukeltje; I ended up using pages 68-71 of the Business Processing Modelling using jBPM 3.2.2 Guide, available via those links that you had provided. I am currently migrating jBPM to a PostgreSQL database, and have made some clarifications to the Guide, which I'll make available on the wiki once I organise access to it; I'm pretty sure that migrating jBPM to a database other than the in-built one (Hypersonic) is a pretty common task.
One thing that wasn't too clear, and something I believe is preventing a log in to the jBPM-console using the new database, is how to populate the JBPM_ID_GROUP, JBPM_ID_USER, and JBPM_MEMBERSHIP tables (logically, not technically). From what I understand, a user who wants to, at least, log into the console needs, at least, a 'user' role. While I understand the (primary key-foreign key) relationships between the tables, it was unclear to me as to:
- the purpose of the TYPE_ field of the JBPM_ID_GROUP.
Any chance you could make clear as to whether or not values in that table field could be preventing valid logins to the console?
I understand that one of the steps involved in migrating jBPM to another database, involves editing the <application-policy> of the login-config.xml (found in <JBPM_JPDL_HOME>/server/server/jbpm/conf/). Instructions for that step read:
"... So before creating a datasource make sure that the datasource has been deployed on the server and the jndi has got registered to the server and is specified appropriately with the login-config.xml Otherwise most of the time a login violation occurs at the jBPM console due to inappropriate jndi specification."
Am I correct in understanding that to mean that my new database should be up and running on the server, before I mess around with login-config.xml? I have a feeling I've misinterpreted that instruction.
Below is a quotation of my login-config.xml.
Any help you could provide, would be much appreciated.
