Hi, are you sure you're sending map messages from Python?
If you use Stomp protocol, you have to send your data xml or json encoded and use "transformation" header to specify how data should be converted to Java. I suggest you read this http://cwiki.apache.org/confluence/display/ACTIVEMQ/Stomp#Stomp-Messagetransformationsand look at StompTest ( http://svn.apache.org/viewvc/activemq/trunk/activemq-core/src/test/java/org/apache/activemq/transport/stomp/StompTest.java?view=markup) for some more examples. You can also use py-activemq (http://code.google.com/p/pyactivemq/) lib which can use OpenWire and CMS API to send map messages naturally.
