      I am running jBPM 3.1, MySql 5.0 startup kit.
      Everyings is fine and all the examples run as they should.
      I have used the PayRaise example and am trying to persist it on the db.
      However i get this error :

      org.hibernate.MappingException: Could not determine type for: string_max, for columns: [org.hibernate.mapping.Column(MESSAGE_)]

          hmmm.. I've seen this problem on CVS head when you update your classes and hibernate mappings without updating your hibernate.cfg.xml.

          Are you sure you are using 3.1?

            Hi Ronald,
            Yes ! I have checked that it is jBPM 3.1.
            I will try to look at hibernate.cfg.xml and see
            if I could make out any thing.
            Thanks for your reply and continued help.

              Hi Ronald,
              Now I have added the line -

              to the hibernate.cfg.xml
              and I get exception :

              The actual file is at : jBPM_HOME\build\classes.jbpm\org\jbpm\context\exe\variableinstance

              Do you know where this file should be located ??

              Thanks in advance for help.

                don't try to add one thing at a time from a newer config to your specific one. Do it the other way around. Add your changes to the new hibernate file and use that from now on. Worked in 5 minutes for me.
