# Example echo TCP

Implements a simple echo service and exposes it using the Aries RSA TCP provider.

# Install

Download Apache Karaf 4.4.6

## Service
Extract to container_a and start. In the shell execute the commands below:

```
feature:repo-add aries-rsa 1.8.0
feature:install scr aries-rsa-provider-tcp aries-rsa-discovery-zookeeper aries-rsa-discovery-zookeeper-server
install -s mvn:org.apache.aries.rsa.examples.echotcp/org.apache.aries.rsa.examples.echotcp.api
install -s mvn:org.apache.aries.rsa.examples.echotcp/org.apache.aries.rsa.examples.echotcp.service
```

The log should show that the service is exported using the tcp provider and published to zookeeper.
It should look similar to this:

```

```

## Consumer
Extract to container_b and start. In the shell execute the commands below:

```
feature:repo-add aries-rsa 1.8.0
feature:install scr aries-rsa-provider-tcp aries-rsa-discovery-zookeeper
install -s mvn:org.apache.aries.rsa.examples.echotcp/org.apache.aries.rsa.examples.echotcp.api
install -s mvn:org.apache.aries.rsa.examples.echotcp/org.apache.aries.rsa.examples.echotcp.consumer
```

The consumer should start and show:
Sending to echo service
Good morning

The log should show that the discovery picks up the endpoint from zookeeper and that the RemoteServiceAdmin imports the service.
