+Camel Servlet REST and OSGi Blueprint example
+=============================================
+
+This example shows how to use Servlet REST to define REST endpoints in Camel routes using the Rest DSL
+
+This example is implemented in XML DSL in the `src/main/resources/OSGI-INF/bluepring/camel.xml` file.
+
+Apache Karaf / ServiceMix
+-------------------------
+You will need to compile this example first:
+ mvn compile
+
+To install Apache Camel in Karaf you type in the shell (we use version ${project.version}):
+
+ features:chooseurl camel ${project.version}
+ features:install camel
+
+First you need to install the following features in Karaf/ServiceMix with:
+
+ features:install camel-servlet
+ features:install camel-jackson
+ features:install war
+
+Then you can install the Camel example:
+
+ osgi:install -s mvn:org.apache.camel/camel-example-servlet-rest-blueprintt/${project.version}
+
+And you can see the application running by tailing the logs
+
+ log:tail
+
+And you can use ctrl + c to stop tailing the log.
+
+
+There is a user REST service that supports the following operations
+
+ - GET /user/{id} - to view a user with the given id </li>
+ - GET /user/final - to view all users</li>
+ - PUT /user - to update/create an user</li>
+
+The view operations are HTTP GET, and update is using HTTP PUT.
+
+From a web browser you can access the first two services using the following links
+
+ http://localhost:8181/camel-example-servlet-rest-blueprint/user/123 - to view the user with id 123
+ http://localhost:8181/camel-example-servlet-rest-blueprint/user/findAll - to list all users
+
+
+From the command shell you can use curl to access the service as shown below:
+
+ curl -X GET -H "Accept: application/json" http://localhost:8181/camel-example-servlet-rest-blueprint/user/123
+ curl -X GET -H "Accept: application/json" http://localhost:8181/camel-example-servlet-rest-blueprint/user/findAll
+ curl -X PUT -d "{ \"id\": 666, \"name\": \"The devil\"}" -H "Accept: application/json" http://localhost:8181/camel-example-servlet-rest-blueprint/user
+
+
+If you hit any problems please let us know on the Camel Forums
+ http://camel.apache.org/discussion-forums.html
+
+Please help us make Apache Camel better - we appreciate any feedback you may
+have. Enjoy!
+

+The Camel riders!
