Therefore, I show here always code snippets for a bean where the method invocation is working (Reference SQLReferences()) and for a bean where the method invocation is not working (Single Food Native SQLSingle Food List()). Reference Remote java:global/Enterprise Application1/EJBModule3/Reference Bean java:app/EJBModule3/Reference Bean java:module/Reference Bean ,289 INFO [org.ejb3.deployment.processors. The J2EE security model declarative in that you describe the security roles and permissions in a standard XML descriptor rather than embedding security into your business component.This isolates security from business-level code because security tends to be more a function of where the component is deployed than an inherent aspect of the component's business logic.Roles defined in the J2EE deployment descriptors should not be confused with the user groups, users, principals, and other concepts that exist in the target enterprise's operational environment.The deployment descriptor roles are application constructs with application domain-specific names.EJBInvocation Invoke(EJBInvocation Handler.java:136) at org.client.

If there are multiple methods with the same overloaded signature, the permission applies to all of the matching overloaded methods.For example, consider an ATM component that is to be used to access a bank account.The security requirements, roles and permissions will vary independently of how you access the bank account, based on what bank is managing the account, where the ATM is located, and so on.For example, a banking application might use role names such as Bank Manager, Teller, or Customer.values to the logical role that the component role references.
