Camel installing dependencies

[Note : Following content is related to a Apache-servicemix-7.0.0.M2 test setup]


When we are creating routing with Camel, we may need to install dependencies to Camel.
As an example if we have created a mail sending route and deploy it in a fresh camel installation, you may get a error like following:

It is because we have not installed a feature called "mail" as a dependency for Camel. There are several dependencies available. We can display them by typing karaf@root>feature:install camel-  and tab.

We can install those dependencies with following command.
karaf@root>feature:install camel-mail  

Now issue should be resolved.
