I am beginner to this and trying to do the sample project which explained here.
HelloProcess Example using JBPM5 Eclipse Plug-in
It was giving some error in "EntityManagerFactory" and UnescalatedDeadlines not found, I fixed these things by placing persistance.xml and orm.xml and mapping the orm inside the persistance and adding h2.jar to classpath.
But now I getting the error,
Error in named query: UnescalatedDeadlines
org.hibernate.QueryException: Unable to render boolean literal value [select new org.jbpm.task.query.DeadlineSummary( t.id, d.id, d.date) from org.jbpm.task.Task t, org.jbpm.task.Deadline d where (d in elements( t.deadlines.startDeadlines ) or d in elements( t.deadlines.endDeadlines ) ) and d.escalated = false order by d.date]
Help me.
