Subject Re: best approach to transfer large File, modify content on receive
Date Wed, 03 Mar 2010 18:06:03 GMT
100 MB isn't really that large. We are sending files >1GB around using the
ActiveMQ's BlobMessage. Why don't you try using that instead of doing
chunking and serialization/deserialization manually?
