Io ancora vedo questo:
codice:
<plugin>


               <groupId>org.apache.maven.plugins</groupId>


               <artifactId>maven-ejb-plugin</artifactId>


               <version>2.3</version>


               <configuration>


                   <!--ejbVersion>3.1</ejbVersion-->


                   <generateClient>true</generateClient>


               </configuration>


           </plugin>
