constant in setProperty is not compatible with property-placeholder Spring context

Hi,

I want to set a constant which is a Spring context property-placeholder. But
it seems Camel is not able to deal with ?

For instance I would like to say:

<camel:setProperty propertyName="MYUSERNAME">
	<camel:constant>${myusername}</camel:constant>
</camel:setProperty>

Instead of hardcoding it into my Camel configuration like this which is less
dynamic:

<camel:setProperty propertyName="USERNAME">
	<camel:constant>john</camel:constant>
</camel:setProperty>

Is there a way to do it ? 

Thanks !

No as the spring property placeholder is invoked by spring and its a
bit limited what you can do in Spring 2.5.
There is in fact a JIRA at Spring that James Strachan filed to enhance
this. Maybe its fixed in Spring 3.0.

Yes my propertyPlaceHolder is set because I also use it like you for my JMS
queue.

But my question is not about the queue but about the camel:constant.

It is not the same thing. If you look at the Camel code you would understand
my question.

Yeah we use this all the time

Do you have your PropertyPlaceholderConfigurer properly defined?
