This example shows how to use a shared Netty HTTP Server in an OSGi environment.
There is 4 modules in this example:
shared-netty-http-server
- The Shared Netty HTTP server that the other Camel applications usesmyapp-one
- A Camel application that reuses the shared Netty HTTP servermyapp-two
- A Camel application that reuses the shared Netty HTTP servermyapp-cdi
- A Camel CDI application that reuses the shared Netty HTTP serverYou will need to compile this example first:
$ mvn install
This example runs in Apache Karaf / ServiceMix. To install Apache Camel in Karaf you type in the shell:
karaf@root()> repo-add camel 2.17.0 karaf@root()> feature:install camel
Then you need to install the following features in Karaf/ServiceMix:
karaf@root()> feature:install camel-netty-http
Then you can install the shared Netty HTTP server which by default runs on port 8888
. The port number can be changed by editing the following source file:
shared-netty-http-server/src/main/resources/OSGI-INF/blueprint/http-server.xml
In the Apache Karaf / ServiceMix shell type:
karaf@root()> install -s mvn:org.apache.camel/camel-example-netty-http-shared/2.17.0
Then you can install the Camel applications:
karaf@root()> install -s mvn:org.apache.camel/camel-example-netty-myapp-one/2.17.0 karaf@root()> install -s mvn:org.apache.camel/camel-example-netty-myapp-two/2.17.0
If you want to test the Camel CDI application, you first need to install the required features:
karaf@root()> feature:install pax-cdi-weld camel-cdi
And then install the Camel CDI application:
karaf@root()> install -s mvn:org.apache.camel/camel-example-netty-myapp-cdi/2.17.0
From a web browser you can then try the example by accessing the followign URLs:
Camel commands can be used to gain some insights on the CDI Camel context, e.g.:
The camel:context-list
displays the CDI Camel contexts:
karaf@root()> camel:context-list Context Status Total # Failed # Inflight # Uptime ------- ------ ------- -------- ---------- ------ camel-1 Started 1 0 0 1 minute netty-myapp-cdi Started 1 0 0 1 minute
Or by tailing the log with:
karaf@root()> log:tail
The following messages should be displayed:
