--------------------------------------------------------------
Hello, I am trying to deploy an external library (javamelody+jrobin) to a JavaEE6 maven project. However it is a requirement that the libraries are "provided scope" and not compiled. Essentially I want to provide the libraries through the JBoss server.

So I have created the two modules as follows as modules in the jboss c:\boss-as-7.1.1.Final\modules\gnu\javamelody\main and c:\boss-as-7.1.1.Final\modules\gnu\jrobin\main

and have included the following code in standalone.xml

  <subsystem xmlns="urn:jboss:domain:ee:1.0"/>
        <global-modules>
             <module name="gnu.javamelody" slot="main"/>
             <module name="gnu.jrobin" slot="main"/>
   </global-modules>
 </subsystem>

in my pom.xml i have the following

<dependency>
     <groupId>net.bull.javamelody</groupId>
     <artifactId>javamelody-core</artifactId>
      <version>1.45.0</version>
      <scope>provided</scope>
 </dependency>

finally I get the following warning from the server log:

Anyone have some idea what's wrong?
