Amit,
Do you mean a streaming download of the format:

while(moreData()) {
Object data = getDataForXRecords();
writeOutDownloadableFileForXRecords(data);
}

Note that this only works for some file formats. Others, such as PDF, require knowing the full length of the file for header info before outputting anything.

This is for the server part. Or do you mean on the client?

ya right..

streaming media

actually i am trying to make a news server...i want to transfer the data to other nodes by concept of streaming media...

Amit,
In that case, the key is to get the data to display in a loop, flushing at the end of each part so the browser gets the data.
