How to trigger so action when ServerletOuput stream writes all data as byte

Question

Hi ,
I have a servlet which accepts the index , size of a .3gp file in bytes as input parameters.
If index=0 ...i am reading whole file into buffered input streame and writing to client as Servlet output steam as bytes.
If index !=0 , or index=100 ...say suppose
im ommiting first 100 bytes and rading101 byte to till the end of file in to buffered input streame and writing to client as Servlet output steam as bytes.
Here i would like to trigger some action when the servlet writes entire bytes to the client .
But im not able to notify exactly when the connection can close between client and server.
Can any one help me to overcome this.
Thanks in advance.

int byteSize = (bif.available() < Integer.parseInt(((DownloadFileForm)o).getSize())) ? bif.available() : Integer.parseInt(((DownloadFileForm)o).getSize());
byte[] b = new byte[byteSize];
bif.read(b, 0, byteSize);
sosStream = response.getOutputStream();
sosStream.write(b);
// here i have to do something
sosStream.close();
logger.info("file has been downloaded from Server is sending out to client");
}catch(Exception e)
