Configuring a Component’s Propagated Security Identity

You can configure an enterprise bean’s run-as, or propagated, security identity using the @RunAs annotation. The RunAs annotation defines the role of the application during execution in a Java EE container. It can be specified on a class, allowing developers to execute an application under a particular role. The role must map to the user/group information in the container's security realm. The RunAs annotation specifies the name of a security role as its parameter.

Here is some example code that demonstrates the use of the RunAs annotation.

@RunAs("Admin")
public class Calculator {
	//....
}

You will have to map the run-as role name to a given principal defined on the Enterprise Server if the given roles associate to more than one user principal. Mapping roles to principals is described in Part VII, Security, in The Java EE 6 Tutorial, Volume II.
