reading http endpoint from properties files
Hi,
I have a route with the endpoint being a HTTP URL.
It so happens that this URL is in a properties file.
Could some one help me to understand how I can dynamically load the end
point name from a property file or in general from header, property etc..?
apparently, none of these work
from("jms:q1")
.to("${properties:httpurl}")
or
from("jms:q1")
.to(header("httpurl"));
or
from("jms:q1")
.to(property("httpurl"));
does not resolve even though the httpurl parameter is present in header as
well as property.
Thanks,
Anand

Hi
what you need is the properties component. Look here:
http://camel.apache.org/properties.html
then you can refer your endpoint like this
.to("{{myHttpEndpoint}}")
where you have that defined in your properties like this:
myHttpEndpoint=http://servername.com/test

I think what you need is a dynamic router
http://camel.apache.org/dynamic-router.html
Did you look at it?

If you want a dynamic to in Camel. Then take a look at this FAQ
http://camel.apache.org/how-do-i-use-dynamic-uri-in-to.html
For example the simple language can access both exchange properties
and the properties placeholder.
If you have a different use-case, then can you explain more why you
want the properties placeholder to access exchange headers? The
properties placeholders is resolved once, and not re-evaluated for
each message, so it cannot access properties from messages.

The Property Place holder did the trick for me.
However, I was hoping if I could extend it to read properties from the
camel exchange .
Any pointers to examples would be welcome.
Thanks,
Anand

Hi
See this FAQ
http://camel.apache.org/how-do-i-use-dynamic-uri-in-to.html
Or you can define the endpoint using property placeholders
http://camel.apache.org/using-propertyplaceholder.html
http://camel.apache.org/how-do-i-use-spring-property-placeholder-with-camel-xml.html
