Subject Re: How to send file using ActiveMQ
Date Fri, 21 Sep 2007 23:16:28 GMT

Try setting the copyMessageOnWrite option to false. I know it's not a good
idea to do that, but it's the only way I got it to make it work. 

I'm supposing that this is not normal behavior and that maybe this issue
will be fixed.
