How to handle the contents of a carousel

Question

Hi,all
Now I have a trouble in how to handle the contents of a carousel.
I use codes below:
          locator=(PMTElementaryStream es).getDvbLocator();
          serviceDomain.attach(locator);
          dsmccObject=new DSMCCObject(serviceDomain.getMountPoint().toString());
          file=new File(serviceDomain.getMountPoint().toString());
          content= file.list();
to get some file or directories, such as *.png, *.class, *.mpg, xml, MHPdataloader, sport, and so on.
How can I do for next procedure.
Thank you.

What do you want to do next? You can create a DSMCCObject that refers to one of the files in your carousel, and use this to control the loading and caching of that file. To actually read a file, however, you will need to create a FileInputStream or RandomAccessFile that refers to that file. You can then use this like any other file access.
This may help you:
// create a new ServiceDomain object to represent
// the carousel we will use
ServiceDomain carousel = new ServiceDomain();
// now create a Locator that refers to the service
// that contains our carousel
org.davic.net.Locator locator;
locator = new org.davic.net.Locator
  ("dvb://123.456.789");
// finally, attach the carousel to the ServiceDomain
// object (i.e. mount it) so that we can actually
// access the carousel.  In this case, we don't specify
// the stream containing the carousel in the locator, so
// we pass in the carousel ID as part of the attach
// request
carousel.attach(locator, 1);
// we have to create our DSMCCObject with an absolute
// path name, which means we need to get the mount point
// for the service domain
DSMCCObject dsmccObj;
dsmccObj = new DSMCCObject(carousel.getMountPoint(),
  "graphics/image1.jpg");
// now we create a FileInputStream instance to access
// our DSM-CC object.  Alternatively, we could create
// a RandomAccessFile instance if we wanted random
// instead of sequential access to the file.
FileInputStream inputStream;
inputStream = new FileInputStream(dsmccObj);
// we can now use the FileInputStream just like any
// other FileInputStream
