Hi
I am experiencing the following problem while doing updates and subsequent
finds on entity beans. The scenario is as follows:
In my code I first find an object via primary key, I then update a field or
two and call setData on the remote interface for the object. If I then do
another find by PK the changed/dirty object is returned and checking in the
log file reveals that a pooled object is returned i.e. there was no DB
access. If I then call a finder method that should return this changed
object, amongst others, e.g. a findAll I do not get the changed/dirty object
but rather one representing the committed data on the DB, for this step the
log file shows DB access as expected.
here is a short code example, that interacts with the entity bean:
TrailerHome trailerHome =
(TrailerHome)EJBUtil.getBeanHome(TrailerHome.JNDI_NAME);
Trailer trailerRemote = trailerHome.findByPrimaryKey(trailerPK);
TrailerData trailerData = trailerRemote.getData();
// change a property
trailerData.setColour("purple");
//update trailer
trailerRemote.setData(trailerData);
// do search by PK, this returns "dirty" object
Trailer pkResult = railerHome.findByPrimaryKey(trailerPK);
// do a search for everything, this does not return the "dirty" object
Collection allTrailers;
allTrailers = trailerHome.findAll();
Has anybody got any ideas as to what I am doing wrong, if anything, or is
this what should be happening. In the above example I could obviously put
the update and find in different transactions but for what I am working on I
need to do an update followed by a find, that includes the changes, and then
an update elsewhere in a single transaction.
thanks
