Hi,
I try to read messages published in a topic of ActiveMq -->
ActiveMQ.Advisory.* but get a type error converter has the body is null
<camel:route>
<camel:from uri="activemq:topic:ActiveMQ.Advisory.*" />
<camel:convertBodyTo
type="org.apache.activemq.command.ActiveMQMessage"/>
<camel:to uri="log:com.elca?showAll=true&multiline=true" />
</camel:route>
How can I avoid this error ?
Causedby: No type converter available to convert from type: null to the
required type: org.apache.activemq.command.ActiveMQMessage with value null.
