== Camel Olingo4 OSGI Example using Blueprint

=== Introduction

This example shows how to use the camel-olingo4 component in an OSGI
environment. We will use the the sample OData 4.0 remote TripPinservice
published on http://services.odata.org/TripPinRESTierService by creating
two People who’s data are loaded from a directory.

==== OSGi / Karaf

This example can be executed within Karaf 4.x. and relies on the
`+camel-olingo4+` feature.

To run the example, from the command line:

[arabic]
. In the Karaf install root directory, start Karaf:
+
[source,sh]
----
$ bin/karaf
----
. Install the pre-requisites:
+
[source,sh]
----
karaf@root()> repo-add camel ${version}
karaf@root()> feature:install camel-blueprint camel-olingo4
----
. Then install and start the example:
+
[source,sh]
----
karaf@root()> install -s mvn:org.apache.camel.example/camel-example-olingo4-blueprint/${version}
----
. Copy the files found in `+src/main/resources+` to the
`+work/odata/input+` in the karaf install root directory created by the
camel route.

By tailing the log with:

[source,sh]
----
karaf@root()> log:tail
----

The following messages should be displayed:
