FinderException not thrown


EJB programming & troubleshooting: FinderException not thrown

  1. FinderException not thrown (1 messages)

    I am developing a CMP EJB which defines acustom finder to locate beans with a particular condition. This condition would retrieve a collection of beans based in the parameter sent.

    I was expecting to receive an Exception whwnever the condition will not retrieve any bean from the DB. I have seen this behaviour when calling a finder method which will retreive a single bean (like the findByPrimaryKey), but my custom finder will retrieve a collection of beans. Problem is that it is not raising the FinderException, is this the normal behaviour? How could I tell that the finder method did not retreive any data?

    Yes this is correct behavour. The spec says for Finders that return Collections the EJB container should return an empty collection rather than throwing an ObjectNotFoundException.
