Problem deploying war file

[David Salter]

Hi,

I'm trying to deploy a war file to a running instance of TomEE.  I'm trying to 
run 

        mvn tomee:deploy

but I get the following error:

[ERROR] Failed to execute goal 
org.apache.openejb.maven:tomee-maven-plugin:1.0.1:deploy (default-cli) on 
project Rest: The parameters 'path' for goal 
org.apache.openejb.maven:tomee-maven-plugin:1.0.1:deploy are missing or invalid 
-> [Help 1]

The plugin is defined in my pom.xml as:

            <plugin>
                <groupId>org.apache.openejb.maven</groupId>
                <artifactId>tomee-maven-plugin</artifactId>
                <version>1.0.1</version>
            </plugin>

If I simply copy my .war file into the web apps folder of TomEE, everything 
works ok.

Can anyone suggest where I'm going wrong?

Thanks.
