Interceptors in seperated jar not working

If a customized interceptor packaged in a jar file placed in EAR\lib as below:
~~~
EAR
----lib/myInterceptor.jar
----myEJB.jar/META-INF/beans.xml
----WAR
~~~

The deployment will fail with below error:
~~~

If package everything in a single WAR, it works fine.
~~~
EAR
----WAR/WEB-INF/myInterceptor.jar
