Error when deploying as ear, ok when deploying as war, why?

Question

Hello all,
I have a strange problem with a JSF project that uses myfaces and shale. I'm using Netbeans 5.5, and all works fine when the web application is deployed independently as a war, but when deploy the full ear i have the following error:
java.lang.NullPointerException
at org.apache.myfaces.taglib.core.ViewTag.doStartTag(ViewTag.java:75)
. I'm using a 'mock' application with no complex ejbs and jsps, so I discard a component problem. Someone have experimented this problem?
Thanks in advance.

Thanks vbk,
I resolved 'partially' the problem not including the myfaces jars in the ear. So the application server uses the sun jsf implementation and all works fine. lamentably I don't know the answer, i suppose a class loading preference problem ... I any case, i would be interested if someone uses the myfaces implementation in the sun app server 9 (myfaces includes some interesting features). I proved the myfaces 1.1.3, 1.1.4 and 1.1.5 versions and all have the same problem.
In relation with this same post, i found anohter problem: shale tiger annotations make jee5 annotations fail. I looked in the shale forums and seems this combination is incompatible. Someone use tiger annotations?
Thanks.
