-------------------------------------------------------------
As a workaround do not use @EndpointInject and use a simple Spring setter
{code:xml}
<bean id="producer" class="org.camel.test.conf.SimpleProducer">
<property name="producer" ref="template"/>
</bean>
<camelContext ...>
<template id="template"/>
...
</camelContext>
{code}
And then use:
{code}
producer.sendBody("activemq:queue: activemq:queue:SendReceiveQueue", "this
is my body");
{code}
And have a setProducer() method on your Producer bean.
