I appreciate your reply, and thanks.
but it still doesn't work!
I create a BLOB message using a File / InputStream as the command argument.
BlobMessage message = session.createBlobMessage(new File("E://test.pdf"));
The sending program seems work fine, but when I tried to get the file data
using a consumer, it gets nothing! (the inputstream I get is null,
therefore, nullpoint exception)
I've tried inputstream way too, but failed again...
I strongly recommend folks try and see what happens about the API...
