pass properties into SMX Camel Route

I need to dynamically configure some Camel route properties (http endpoint
URL, etc) based on a properties file.  What is the best way to do this?

I thought I could create a local.properties file and use Spring's
PropertyPlaceholderConfigurer, but I'm not sure how this works with Camel
DSL exactly...

here is what I have today...

local.properties file with a property "inboundURL=http://test.com"

MyRouteBuilder.java with a hardcoded URL

String inboundURL = "http://test.com"   //TODO: need to be from prop file
...
from("jetty:" + inboundURL)
.to("activemq:GatewayMsgQueue");
...

thanks

Using ClassLoader.getResourceAsStream(), the file has to be in the 
classloader.

Basicly, you can add a new classpath entry in the servicemix startup 
script (for example etc/my-config and update the CLASSPATH).

Putting it in your project resources directory is not good as this 
properties file needs to be changed by the users I guess.

that is what I was looking for...one last question, where would the
"my.properties" file need to be located...or how would it be added to the
path to be made available exactly...thanks again

Ah OK Ben,

using Java, you can construct the URIs by hand and provide in endpoint.

For example, you can use system wide properties, or load a properties 
file from the classpath (or using Spring resource):

Properties properties = new Properties();
properties.load(this.getClass().getClassLoader().getResourceAsStream("my.properties");
String route = properties.getProperty("route_endpoint");
String jbiEndpoint = "jbi:" + route:
from("timer:mytime").to(jbiEndpoint);

in your RouteBuilder configure() method.

I never tried this but it should work.

Regards
JB

thanks.  I saw this article earlier, but I'm using the Java DSL (not XML) to
configure my routes.  How do I pass/access these properties from
MyRouteBuilder.java file?

Overall, are there other ways to get machine specific properties into SMX
builds (System properties, etc) besides the Spring configuration?

Hi Ben;

Charles Mouillard from Camel has blog this:
http://cmoulliard.blogspot.com/2009/05/trick-to-pass-uri-declared-in-property.html

Anyway, if you can use property directly into Camel URIs, you can use 
endpoint definition like this:
<beans xmlns="http://www.springframework.org/schema/beans"
        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
        xsi:schemaLocation="
        http://www.springframework.org/schema/beans 
http://www.springframework.org/schema/beans/spring-beans-2.0.xsd
        http://activemq.apache.org/camel/schema/spring 
http://activemq.apache.org/camel/schema/spring/camel-spring.xsd
     ">

   <bean 
class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer"/> 


   <camelContext xmlns="http://activemq.apache.org/camel/schema/spring">
     <endpoint id="input1" uri="activemq:${someQueueName}"/>

     <route>
       <from ref="input1"/>
       <to uri="activemq:OutputQueue"/>
     </route>
   </camelContext>


</beans>

JB
