Latest release of UIMA AS is missing a number of ActiveMQ jars that support messaging over http. UIMA AS Extended test suite use maven and its dependency resolution to help find all the needed jars so the problem was not discovered until UIMA AS was run stand alone outside of eclipse. When trying to use http protocol the following exception is thrown:
ERROR BrokerService - Failed to start ActiveMQ JMS Message Broker. Reason: java.io.IOException: Transport Connector could not be registered in JMX: Transport scheme NOT recognized: [http]
Install a full version of ActiveMQ from http://activemq.apache.org/ and, before starting UIMA AS service, modify environment by setting ACTIVEMQ_HOME to point to the location where ACTIVEMQ is installed.
