The resource injection and security annotations are defined in the Common
Annotations for the Java Platform specification, and are in the javax.annotation
and javax.annotation.security packages. For example, the @Resource injection
may be used to inject a javax.sql.DataSource resource. First, configure a
data source in a Java EE container. Subsequently, inject a data source handle by
annotating a declaration for a variable of type javax.sql.DataSource with the @
Resource annotation.

@Resource
private javax.sql.DataSource mysqlDS;
public getCatalogEntry(){
Connection conn = mysqlDS.getConnection();
}

Data source injection using the @Resource annotation precludes the requirement
for JNDI lookup using an InitialContext object. The security annotations are
presented in the following table.

Annotation Description

DeclareRoles Declares references to security roles

RolesAllowed Declares the methods that are allowed to invoke the methods of the

entity bean

PermitAll Specifies that all security roles are allowed to invoke the specified

methods.

DenyAll Specifies that no security roles are allowed to invoke the specified

methods.

RunAs Specify a security role as the bean's run-as property.
