Generate XmlRootElement for jaxb objects

I recently had to add XmlRootElement to a class. After using google for a while, I finally figured out a way to do it. I Updated the pom jaxb plugin to include the annotate plugin and created a mappings file that customizes the jaxb object. pom.xml:

<plugin>
    <groupid>org.jvnet.jaxb2.maven2</groupid>
    <artifactid>maven-jaxb2-plugin</artifactid>
    <configuration>
        <extension>true</extension>
        <strict>false</strict>
        <plugins>
            <plugin>
                <groupid>org/jvnet/jaxb2_commons</groupid>
                <artifactid>annotate</artifactid>
                <version>0.4.1.5</version>
            </plugin>
        </plugins>
    </configuration>
    <executions>
        <execution>
            <id>generate</id>
            <goals>
                <goal>generate</goal>
            </goals>
            <configuration>
                <bindingincludes>
                    <include>*.xjb</include>
                </bindingincludes>
                <args>
                    <arg>-Xannotate</arg>
                </args>            
            </configuration>
        </execution>
    </executions>
</plugin>

file.xjb:

</jaxb:bindings>
