Hi Claus,
Current camel support to define a producer template OUTSIDE a camel
context, I think it works well just like the autowire function which is
provided in Spring.
If there more than two Camel context in the Spring Application context ,
the user should specify the camel context which the template should use.
But I have a concern that even we put the template INSIDE the camel
context, the template will not be set with a right version of camel
context, since we use a CamelPostProcessor to inject CamelContext.
So I did a quick test on the current Camel code and found there is a bug
if there are more one CamelContext -- CamelPostProcessor will inject
the last create camel context into the CamelContextAware object.
I suggest to change the CamelPostProcessor to skip bean which
camelContext is set, but it need to change the CamelContextAware
interface to add a method of getCamelContext.
Any thought ?

Hi Willem
I actually didnt realize you could define a producer template OUTSIDE
a camel context.
I do think that is WRONG. As the template needs to hold a reference to
a CamelContext to work correctly.
But when people have 2+ camel context defined in the XML files then it
gets tricky, as which CamelContext should the template belong to.
I believe we should do the opposite and remove the option to define it
outside and only allow it to be defined within a camel context.
If not it should at least require a context attribute as well so you
can define which camel context it belongs to.

Hi,
I just found this is a bug of Camel. I'm working on the quick fix now[1].
Here is a way that you can walk around this issue, by putting the
consumerTemplate definition inside the camel context.
<camel:camelContext id="camel">
<camel:consumerTemplate id="consumer"/>
</camel:camelContext>
<camel:template id="producer"/>

Which version of Camel are you using ?
I just checked current Camel 2.0 trunk code, the <camel:consumer> tag
should work. Can you try to use the recent released Camel 2.0 M3 ?
