Hi While using workflow persistence feature (with human task component), I am having quite a few problems. When I use default db (H2), I get ConstraintViolationException [1]. Since I have to ultimately integrate with Oracle, I modify the config files to point to Oracle. But with that I started getting lot of other issues, like invalid column names (size, date), invalid table name (Comment), SQLGrammarException, etc[2] (This is serious problem, if you use Oracle!) I am struggling for quite a few days to get this work, but no success, any help would be greatly appreciated. I am attaching the source code also[3].
