In the jbpm 3.2 source, in the db module, there is an ant script that generates update scripts. It uses the class JbpmSchemaTask from /modules/core/src/main/java/org/jbpm/ant. Never used it, so not sure how it exactly works. But it is a schema update. Not sure if all data in it is still valid then (e.g. new colums with 'not null' etc) View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4217485#...
