    Drools 5.x + jBPM 5.x + Hibernate 3.6.x + Postgres 9.x - bug

    Krešimir Popović Newbie

      Hello,

       

      does anyone know if jBPM was tested with Hibernate 3.6.x (part of JBoss 6.x) ?

       

       

      I just want to know if JBPM 5.x tested with hibernate 3.6.x/Postgres 9.x ? Hibernate team has done some changes since hibernate 3.5.x regarding bytea / oid data type handling.

      This is the error I get when I execute Mina task client method: getTasksAssignedAsPotentialOwner

        Hint: You will need to rewrite or cast the expression.

        Position: 100

      sion: org.hibernate.exception.SQLGrammarException: could not insert: [org.drools.persistence.info.SessionInfo]

              at org.hibernate.exception.SQLStateConverter.convert(SQLStateConverter.java:92) [:3.6.0.Final]

       

      I get also the same thing for processinstanceinfo -->  COLUMN processinstancebytearray

       

      Problematic Entity classes:

      org.drools.persistence.processinstance.ProcessInstanceInfo

      org.drools.persistence.processinstance.SessionInfo

       

       

      Maybe what is needed to do is to make correction in Drools product. processinstancebytearray and rulesbytearray fields should be marked with annotation @Type(type="org.hibernate.type.PrimitiveByteArrayBlobType")?

       

       

      Best Regards,

      Krešimir
