+# Camel Swagger OSGi Example
+
+### Introduction
+This is an example that uses the rest-dsl to define a rest services which provides three operations
+
+- GET user/{id} - Find user by id
+- PUT user - Updates or create a user
+- GET user/findAll - Find all users
+
+### Build
+You will need to compile this example first:
+
+ mvn compile
+
+### Run
+This example needs to be deployed on Apache Karaf/SerivceMix first:
+
+ feature:repo-add camel ${version}
+ feature:install camel
+ feature:install camel-jackson
+ feature:install camel-jetty
+ feature:install camel-swagger-java
+
+And then install the example
+
+ install -s mvn:org.apache.camel/camel-example-swagger-osgi/${version}
+
+
+The rest service can be accessed from the following url
+
+ curl http://0.0.0.0:8080/camel-example-swagger-osgi/rest/user
+
+<http://0.0.0.0:8080/camel-example-swagger-osgi/rest/user>
+
+For example to get a user with id 123
+
+ curl http://0.0.0.0:8080/camel-example-swagger-osgi/rest/user/123
+
+<http://0.0.0.0:8080/camel-example-swagger-osgi/rest/user/123>
+
+The rest services provides Swagger API in json or yaml format
+which can be accessed from the following url
+
+ curl http://0.0.0.0:8080/camel-example-swagger-osgi/rest/api-docs/myCamel/swagger.json
+ curl http://0.0.0.0:8080/camel-example-swagger-osgi/rest/api-docs/myCamel/swagger.yaml
+
+<http://0.0.0.0:8080/camel-example-swagger-osgi/rest/api-docs/myCamel/swagger.json>
+
+
+### Forum, Help, etc
+
+If you hit an 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!
+
