Hi, I'm a newbie for JBPM so bear with me... We had JBPM 3.2.3 running on JBOSS app server using Hypersonic as db. We had cdeployed som processes, tested them with the jbpm-console and everything seemed to work fine. Then we replaced the hypersonic db by an Oracle 10g database. When starting the app server, all the tables are created. When starting the jbpm-console we can see our pdeployed process. So far so good. The problem starts when we want to start an instance of the deployed process : Then we get the followiong exception: . 2008-10-31 15:46:08,370 DEBUG [org.hibernate.util.JDBCExceptionReporter] could
