Subject: Using http transport from a Perl client
MIME-Version: 1.0
Content-Type: text/plain; charset=us-ascii
Content-Transfer-Encoding: 7bit


Hi All,
I am experimenting with ActiveMQ 5.0, & my clients are in Perl. While
tinkering around, I managed to get Java clients to communicate with the
broker using http.
It seems that JMS commands are serialized into xml using XStream & sent over
http. The broker deserializes them using XStream.
When I tried sending http messages from Perl (using LWP & simple xml as the
content of the messages), I got the following error on the broker:

ERROR log                            - /topic/fooHTTP
