39  * are not to be checked for authorization, and a list of method elements.
40  * The security roles used in the method-permission element must be
41  * defined in the security-role element of the deployment descriptor,
42  * and the methods must be methods defined in the enterprise bean�s component
43  * and/or home interfaces.
