Using Apache camel in bundles on Apache karaf

I'm trying to write the content of some files into the log file of Apache karaf (just for some testing). To do that I use the following Route with Camel:

from("file:C:/input?noop=true").process(new LogProcessor()).to(
            "stream:out");

The LogProcessor does nothing right now and my pom.xml looks like this (building it with maven):

    <?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0      http://maven.apache.org/xsd/maven-4.0.0.xsd">

I also executed

features:install camel-stream

on karaf and of course camel itself is also installed on karaf.

But still I get the

[...]No component found with scheme: stream[...]

Error on karaf.

Already looked through a lot of Forums and stuff but couldn't find any solution...any help is appreciated!

This is bit of a hunch but I'm guessing you've created DefaultCamelContext inside bundle Activator. Then Stream Component is not loaded in to that context unless you do it yourself like this: 

StreamComponent stream = new StreamComponent();
camelContext.addComponent("stream", stream);
