Problem accessing EJB

Hi,

when i try to get an instance of a stateless EJB through its creat() method, I've got this:

#1#com.sap.engine.services.ejb.exceptions.BaseRemoteException: User Guest does not have access to method create().

I have set permission to this EJB in ejb-jar.xml:

<security-role-ref>

<role-name>all</role-name>

<role-link>all</role-link>

</security-role-ref>
