dynamic properties
I need to have configurable text with some parameters to set in the body.
In my .cfg file I have
message=My message ${property.type} is for user ${property.user}
Properties are set in steps before.
If I use setBody(simple("{{message}}") I get text without properties
parameters. Any ideas how to set body with needed parameters?
Other similar problem is when I need to get property by dynamic name
Something like setHeader("My",
simple("{{userName."+"${property.name}"+"}}")). Something like that, but I
do get an error if I try to execute this, as property.name doesn't produce
property value... Any ideas?
Thank you a lot

I think you are looking for a template engine like [1], [2] or [3].
[1] http://camel.apache.org/freemarker.html
[2] http://camel.apache.org/velocity.html
[3] http://camel.apache.org/stringtemplate.html
Best,

You need a newer release of Camel like 2.9 onwards to do this.
For example if you use Apache ServiceMix 4.5.x, that comes with Camel 2.10.x

I use camel 2.8 according my serviceMix server.
In cfg I have:
message=My message ${property.type} is for user ${property.user}
messageSubject.invoice=Invoice message
I use Java DSL to define route and osgi blueprint for other purposes. My
route looks like:
from("direct:start")
.to("bean:FindXML")
.setProperty("type", xpath("/message/@Type"))
.setProperty("user", xpath("/message/@To"))
.to("bean:SomeActions")
.setHeader("messageText", simple("{{message}}"))
.setHeader("messageSubject", simple("{{messageSubject.${property.type}}}"))
None of this header setters work.

Hi
See this page how to use property placeholders with Camel
http://camel.apache.org/using-propertyplaceholder.html
What version of Camel do you use?
And do you use Spring or OSGi blueprint, or something?
And what is ${property.type}
is that another property placeholder with a key=type,eg
eg from a .cfg or .properties file you have:
type=Some bla goes here
user=Some other bla here
message=My message ${property.type} is for user ${property.user}
