Runnning the Examples
=====================
To run any example, simply `cd` into the appropriate example directory
and type `mvn verify` or `mvn install` (For details please read the readme.html in each
example directory).

You can use the profile -Pexamples to run multiple examples under any example tree.

For each server, you will have a created server under ./target/server0 (some examples use more than one server).
For each server, you will have a created server under `./target/server0` (some examples use more than one server).
You have the option to disable the server running (say if you want to start the server manually) by simply specifying the -PnoServer profile
This will run the example without a server:
You have the option to prevent the example from starting the server (e.g. if you want to start the server manually) by
simply specifying the `-PnoServer` profile, e.g.:
``` sh
# running an example without running the server
mvn verify -PnoServer
```
Also under ./target there will be a script repeating the commands to create each server:
Also under `./target` there will be a script repeating the commands to create each server. Here is the `create-server0.sh`
generated by the `Queue` example. This is useful to see exactly what command(s) are required to configure the server(s).
Example this is create-server0.sh created for the queue example. It could be useful to see what we do on the example:
```sh
# These are the commands used to create server0
/myInstallDirectory/apache-artemis-1.1.0/bin/artemis create --allow-anonymous --silent --force --no-web --user guest --password guest --role guest --port-offset 0 --data ./data --allow-anonymous --no-autotune --verbose /myInstallDirectory/apache-artemis-1.1.0/examples/features/standard/queue/target/server0
```
These examples are all using the [Maven plugin](maven-plugin.md), which can be useful for running your test servers as well.
Several examples use UDP clustering which may not work in your environment by default. On linux the command would be:
``` sh
route add -net 224.0.0.0 netmask 240.0.0.0 dev lo
```
This command should be run as root. This will redirect any traffic directed to `224.0.0.0` to the loopback interface.
On Mac OS X, the command is slightly different:
This is the common output when running an example. On this case taken from the Queue example:
``` sh
sudo route add 224.0.0.0 127.0.0.1 -netmask 240.0.0.0
```
