hi all
can anybody clear my doubt regarding the servicedomain.attach() function in org.dvb.dsmcc. The attach() function says to mount the carousel to the local filesystem, does it mean that the receiver has to transfer the whole object carousel in broadcast network to the local filesystem so that later when an application asks for a file it can take it from the local filesystem. hoping to receive response

No it doesn't mean this. All it means is that the files will appear there
if asked for. They still need to be fetched from the network, either when
they're asked for by an application or perhaps speculatively (as an
optimisation).
The term "mount" in MHP has the same meaning as when a
NFS file system from a file server is mounted in a Linux or Unix
computer. The files stay on the server with a local cache of some
kind in the client.
If you're implementing MHP/OCAP then some integration between the implementaiton of the java.io packages and the implementation of DSMCC is needed. This is probably a lot easier if changes are made to the implementation of java.io however I'm told there are people who've implemented MHP with J2SE without making any changes. If this is correct and they pass the MHP test suite then they have my admiration.
