How to get the System Environment variable inside camel context

[niteshjain132]

I have a system variable "JBOSS_FUSE_HOME" and in my camel context i tried this

<camelContext trace="false" id="Camel"  xmlns="http://camel.apache.org/schema/spring">

.....

.....

     <route id="loadtoMemory">

            <from  uri="cxf:bean:demo-ws" />

            <process ref="responseCacheLoadingAction" />

            <log message="${JBOSS_FUSE_HOME}"/>

  </route>

</camelContext>

Exception in thread "SpringOsgiExtenderThread-14" org.apache.camel.RuntimeCamelException: org.apache.camel.FailedToCreateRouteException: Failed to create route loadtoMemory at: >>> Log[${JBOSS_FUSE_HOME}] <<< in route: Route(loadtoMemory)[[From[cxf:bean:demo-ws... because of Unknown function: JBOSS_FUSE_HOMEat location 0

${JBOSS_FUSE_HOME}

*

any help on how to access the System environment variables in camel context.xml would be appreciated.

Thanks,

Nitesh

Using system and environment variables in locations

Available as of Camel 2.7

The location now supports using placeholders for JVM system properties and

OS environments variables.

For example:

location=file:${karaf.home}/etc/foo.properties

In the location above we defined a location using the file scheme using the

JVM system property with key karaf.home.

To use an OS environment variable instead you would have to prefix with env:

location=file:$/etc/foo.properties

Where APP_HOME is an OS environment.

You can have multiple placeholders in the same location, such as:

location=file:$/etc/${prop.name}.properties

Using out of the box functions

Available as of Camel 2.14.1
