by default we are using H2, an in memory database.. which is wipe out when you shutdown the server. You should change to a real database like MySQL, PostgreSQL to keep that up with the information.
already I changed the H2 database to mysql, I did change in the persistence.xml in task service and gwt console war in the lib too. I changed the autodll to 'update' not create,
still this problem exists,
Sounds like you are not changing the one which is doing the clean up of the databases.
DId you change the ddl in both?
all the persistence.xml,,,,in jbpm-install demo..I changed to "update"
in lib folder --> gwt-console.wat and task.war etc...
Any solution for this now?
I ran into the same problem.
