Hi,
how is everyone today?
i have a really really weird problem.
here is what is happening:
i have show bean and a songFile bean( both entity beans )
i have show table and songFile table and songs_in_the_show_table
inside show bean i have a methods
class ShowBean extends EntityBean{
private Collection _collectionOfSongs;
add( SongFileRemoteI songFile ){
// simplified code
_loadSongCollection();
_collectionOfSongs.add( songFile );
}
remove( SongFileRemoteI songFile ){
_loadSongCollection();
_collectionOfSongs.remove( songFile );
}
private void addToDB( SongFileRemoteI songFile){
// perform necessary db calls to make a add to table statement
}
private void remoteFromDB( SongFileRemoteI songFile){
// perform necessary db calls to make a delete to table statement
}
private void _loadSongCollection(){
// simplified code
if ( _collectionOfSongs == null ){
SongFileHome home = BeanBroker.getSongHome();
Enumeration enum = home.findSongForShow( this.getID() );
while ( enum.hasMoreElements() ){
// ....
_collectionOfSongs .add( enum.nextElement() );
//....
} // while
} // if
} // _loadSongCollection
}
now something really interesting happens.
when i call remove, it removes the song correctly, from both the
collection and the db, BUT as soon as i start the client again, it is
as if i never removed it! it is again in the collection ( it is not in
the db ).
if i shutdown Jboss and start it again, collection would be of correct
size.
so what is going on? is there something that i am missing ? is this
legal?
let me know.
alex k.
