Thank you for your answer.
Actually in my ear there were more then one time the same ejb:
myear.ear
mywar.war
myejb.jar
myejb.jar
and this was working in JBoss 5.
I'm packaging my application with maven so now I've changed the dependencies in
the pom.xml of the "war project" updating the scope of the ejb project to
provided:
<dependencies>
<!-- javaee per ejb -->
<dependency>
<groupId>javaee</groupId>
<artifactId>javaee-api</artifactId>
<version>5</version>
<scope>provided</scope>
</dependency>
<dependency>
<groupId>org.jboss.resteasy</groupId>
<artifactId>resteasy-jaxrs</artifactId>

</dependency>
* <dependency>

</dependency>*

<dependency>

<dependency>

</dependency>

</dependency>
<!-- test -->

</dependencies>
Now the ejb isn't included in the war and I can compile, package and start the
application but when in the application calls the ejb I recieve this error:
10:01:24,604 ERROR

In the ejb GimovitCoreBean at line 50, I call an Entity Bean but I've recieved no
errors with the persistence unit.
I don't understand if there is something wrong in my configuration, can you suggest me
where I have to make changes?
Thank you for the help.
