+# Apache Karaf Camel Example
+
+## Abstract
+
+This example shows how to use Apache Camel in Karaf. Apache Camel is a
integration framework, allowing you to integrate several systems and
applications all together.
+
+Apache Camel supports several DSL. This example shows how to use the Camel
Java DSL and the Camel Blueprint DSL.
+
+It creates several Camel routes, exposing a HTTP endpoint and using a Content
Based Router EIP (Enterprise Integration Pattern).
+
+## Artifacts
+
+* **karaf-camel-example-java** is a bundle containing routes described using
the Camel Java DSL.
+* **karaf-camel-example-blueprint** is just a wrapper containing routes
described using Blueprint. Karaf supports deployment of this DSL directly (in
the deploy folder for instance) or packaged as a bundle.
+* **karaf-camel-example-features** provides a Karaf features repository used
for the deployment.
+
+## Build
+
+The build uses Apache Maven. Simply use:
+
+```
+mvn clean install
+```
+
+## Feature and Deployment
+
+On a running Karaf instance, register the features repository using:
+
+```
+karaf@root()> feature:repo-add
mvn:org.apache.karaf.examples/karaf-camel-example-features/4.2.2-SNAPSHOT/xml
+```
+
+Then, you can install either Camel Java or Blueprint features:
+
+```
+karaf@root()> feature:install karaf-camel-example-java
+```
+
+```
+karaf@root()> feature:install karaf-camel-example-blueprint
+```
+
+## Usage
+
+Once you have install a Camel feature, the main route is started and bind a
HTTP endpoint on `http://localhost:9090/example`.
+
+We can test payloads testing different paths of the content based router.
+
+First, let's try an e-mail request:
+
+```
+curl -X POST -H "Content-Type: application/json" http://localhost:9090/example
-d '{ "notification": { "type": "email", "to": "f...@bar.com", "message": "This
is a test" }}'
+```
+
+You can see in the log that the e-mail route has been called in the log:
+
+```
+karaf@root()> log:display
+10:24:22.453 INFO [qtp1790923892-140] [EXAMPLE INBOUND] Received: {
"notification": { "type": "email", "to": "f...@bar.com", "message": "This is a
test" }}
+10:24:22.465 INFO [qtp1790923892-140] [EXAMPLE INBOUND] Received email
notification
+10:24:22.466 INFO [qtp1790923892-140] [EXAMPLE EMAIL] Sending notification
email
+```
+
+And we have the curl response confirming it:
+
+```
+{ "status": "email sent", "to": "f...@bar.com", "subject": "Notification"}
+```
+
+We can also test the `http` path of the content based router:
+
+```
+curl -X POST -H "Content-Type: application/json" http://localhost:9090/example
-d '{ "notification": { "type": "http", "service": "http://foo"; }}'
+```
+
+We can see the response confirming the call to the http route path:
+
+```
+{ "status": "http requested", "service": "http://foo"; }
+```
+
+and the corresponding log messages:
+
+```
+11:17:28.372 INFO [qtp1790923892-138] [EXAMPLE INBOUND] Received: {
"notification": { "type": "http", "service": "http://foo"; }}
+11:17:28.374 INFO [qtp1790923892-138] [EXAMPLE INBOUND] Received http
notification
+11:17:28.374 INFO [qtp1790923892-138] [EXAMPLE HTTP] Sending http notification
+```
