271. What is security permission set
The minimum set of security permissions that a J2EE
product provider must provide for the execution of
each component type.
272. What is security policy domain
A scope over which security policies are defined and
enforced by a security administrator. A security
policy domain has a collection of users (or
principals), uses a well-defined authentication
protocol or protocols for authenticating users (or
principals), and may have groups to simplify setting
of security policies.
273. What is security role
An abstract logical grouping of users that is defined
by the application assembler. When an application is
deployed, the roles are mapped to security identities,
such as principals or groups, in the operational
environment. In the J2EE server authentication
service, a role is an abstract name for permission to
access a particular set of resources. A role can be
compared to a key that can open a lock. Many people
might have a copy of the key; the lock doesn't care
who you are, only that you have the right key.
274. What is security technology domain
A scope over which the same security mechanism is used
to enforce a security policy. Multiple security policy
domains can exist within a single technology domain.
275. What is security view
The set of security roles defined by the application
assembler.
276. What is server certificate
Used with the HTTPS protocol to authenticate Web
applications. The certificate can be self-signed or
approved by a certificate authority (CA). The HTTPS
service of the Sun Java System Application Server
Platform Edition 8 will not run unless a server
certificate has been installed.
277. What is server principal
The OS principal that the server is executing as.
278. What is service element
A representation of the combination of one or more
Connector components that share a single engine
component for processing incoming requests.
279. What is service endpoint interface
A Java interface that declares the methods that a
client can invoke on a Web service.
280. What is servlet
A Java program that extends the functionality of a Web
server, generating dynamic content and interacting
with Web applications using a request-response
paradigm
