How to read Oracle OAQ queue from Camel - oracle

Question

I am writing a Camel app that reads LCR's from an Oracle oaq ("ANYDATA") queue. We are not using Weblogic, and are running under Spring Boot. Right now I'm trying to create a minimal app that reads the LCR's and dumps them to a log. We are getting an exception (full trace shown at bottom) that says:
c.c.j.DefaultJmsMessageListenerContainer : Setup of JMS message listener invoker failed for destination 'AQADMIN.MULEBUS_ANYDATA_Q' - trying to recover. Cause: JMS-120: Dequeue failed; nested exception is oracle.jms.AQjmsException: JMS-224: Typemap is invalid - must be populated with SQLType/OraDataFactory mappings to receive messages from Sys.AnyData destinations
I think I need to grab the session and populate the type map. The LCR's are in XML format; from 1 example on the web I saw I could probably do something like this:
((AQjmsSession) session).getTypeMap().put(("SYS.XMLTYPE", Class.forName("oracle.xdb.XMLType"));
.. but I am a Camel newbie (not to mention an ANYDATA newbie), and am not sure whether that will work or how to do it. Also wondering whether I am using the wrong driver (I see stuff indicating the thin driver (which I am using), other stuff pointing to oci. Note that we're connecting, as nothing happens till we generate an lcr.
Any pointers on how to set up a minimal app to read the lcr in Camel and dump it to a log would be most gratefully appreciated.
The route looks like this currently:
from("oracleAQ:{{xyz.oracleaq.datasource.srcaq}}")
.to("log:out");
.. and the referenced component is:
#Qualifier("oracleAQ")
#Bean
public Object oracleAQ() throws JMSException {
LOG.info("OracleAQ startup - url={}, user={}", url, username);
try {
QueueConnectionFactory f = AQjmsFactory.getQueueConnectionFactory(url, new Properties());
UserCredentialsConnectionFactoryAdapter adapter = new UserCredentialsConnectionFactoryAdapter();
adapter.setTargetConnectionFactory(f);
adapter.setUsername(username);
adapter.setPassword(password);
return JmsComponent.jmsComponent(adapter);
} catch (JMSException jmse) {
LOG.error("Error starting OracleAQ component: {}", jmse);
throw jmse;
}
}
TIA.
