Subject Re: Problems with acknowledge mode order (STOMP)
Date Mon, 26 Jan 2009 08:19:23 GMT
It would be ideal to create a test case using simple Java API

http://activemq.apache.org/stomp.html#Stomp-JavaAPI

and add it to the

http://svn.apache.org/viewvc/activemq/trunk/activemq-core/src/test/java/org/apache/activemq/transport/stomp/StompTest.java?view=markup

If Perl is easier for you, just send it and I'll translate it to the Java
test case.

Cheers
