"Exception thrown in non-transactional EJB invoke"

Question

          When I throw an application exception from within a statless session bean which uses jdbs for DB Lookup Only I get
          "Exception thrown in non-transactional EJB invoke".
          As this is a llokup only I have no Transaction Management
          

Answer 1

Tao,
          > If your ejb method is in a transaction context, then you throw application
          exception, the container will try to commit the transaction.
          In the case of an application exception, the caller will be responsible for
          committing or rolling back the transaction. (A runtime exception will roll
          back the transaction automatically.) That is why, if you use CMT, that the
          EJB methods call from outside the EJB container (such as from a servlet)
          should never be able to throw runtime exceptions.
