public class ConfigFile extends Configuration
javax.security.auth.login.Configuration
.
This object stores the runtime login configuration representation,
and is the amalgamation of multiple static login
configurations that resides in files.
The algorithm for locating the login configuration file(s) and reading their
information into this Configuration
object is:
java.security.Security
properties,
login.config.url.1, login.config.url.2, ...,
login.config.url.X. These properties are set
in the Java security properties file, which is located in the file named
<JAVA_HOME>/lib/security/java.security.
<JAVA_HOME> refers to the value of the java.home system property,
and specifies the directory where the JRE is installed.
Each property value specifies a URL
pointing to a
login configuration file to be loaded. Read in and load
each configuration.
java.lang.System
property
java.security.auth.login.config
may also be set to a URL
pointing to another
login configuration file
(which is the case when a user uses the -D switch at runtime).
If this property is defined, and its use is allowed by the
security property file (the Security property,
policy.allowSystemProperty is set to true),
also load that login configuration.
The configuration syntax supported by this implementation
is exactly that syntax specified in the
javax.security.auth.login.Configuration
class.
