Re: How can an Entity Bean communicate with other Entity Bean?

[Hicks, James]

Title: Message

IReadonly beans are designed to load "read only" data.  It seems like you are trying to do some type of data caching.  Well most app servers will cache an entity bean for you, so there is no need to do what you are doing.  I would change your read-only bean to a standard entity bean and tell your app server to cache the bean instance for you.

         Yes, the read-write entity bean modifies the data in the database that the read-only bean reads. In so far as

          the read-only entity bean reads from the database immediately after read-write bean modifies, it has good

          data, but the moment read-write bean modifies the data, the contents of read-only bean are state and dirty

          until its next load from database. And that is why I want to know how to clue-in the read-only bean that

         its data is stale, immediately after read-write bean modifies.

         Thanks

Why would you need to reload the read-only bean?  Are you modifing the data in the database that the readonly bean reads?

   I have two Entity Beans, representing same underlying data, but one of
   the beans is Read-Write while other one is Read-Only Entity Bean.
   And when my Read-Write Entity Bean modifies its contents, I want to
   somehow communicate to Read-Only Entity Bean to reload itself.
   Any ideas/insights/suggestions are very much appreciated.
   (All I know for now is to set the time-out setting for Read-Only Entity
   Bean low enough to make it periodically load itself)
   Thanks
