# Package your application

The package goal allows you to provision a server using Galleon, execute CLI commands and scripts to fine tune the server configuration, copy some extra content (e.g.: keystore, properties files) to the server installation and finally deploy your application.

By default the server is provisioned in the `target/server` directory.

## Package a JAXRS application

The example below shows how to produce the latest released WildFly server trimmed using ‘jaxrs-server’ Galleon layer.

    <project>
        ...
        <build>
            ...
            <plugins>
                ...
                <plugin>
                    <groupId>org.wildfly.plugins</groupId>
                    <artifactId>wildfly-maven-plugin</artifactId>
                    <version>4.2.2.Final</version>

                        <feature-packs>
                            <feature-pack>
                                <!-- Latest released version -->
                                <location>wildfly@maven(org.jboss.universe:community-universe)</location>
                            </feature-pack>
                        </feature-packs>
                        <layers>
                            <!-- Galleon layer allows to trim the installed server to your needs. The 'jaxrs-server'
                            contains the server content required to execute JAXRS applications -->
                            <layer>jaxrs-server</layer>
                        </layers>
                    </configuration>
                    <executions>
                        <execution>
                            <goals>
                                <goal>package</goal>
                            </goals>
                        </execution>
                    </executions>
                </plugin>
                ...
            </plugins>
            ...
        </build>
    ...
    </project>

## Fine tune server configuration and package extra content

The example below shows how to configure the plugin goal to execute CLI commands and copy extra content inside the installed server:

    <project>
        ...
        <build>
            ...
            <plugins>
                ...
                <plugin>

                            You don't need to start and stop the embedded-server. -->
                            <execution>

                            </execution>

                        <!-- A list of directory that contains content to copy to the server. Each directory must contain a

## Deploy your WAR application in the root context

By default the name of the WAR is used as the runtime-name for your deployment. You can specify a runtime-name parameter to tune the context in which your deployment will be registered. In this example we are using the special ‘ROOT.war’ runtime-name to reference the root context.

    <project>
        ...
        <build>
            ...
