public class ConfigFile extends Configuration
This class represents a default implementation forjavax.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
Configurationobject is:-
Loop through the security properties,
login.config.url.1, login.config.url.2, ...,
login.config.url.X.
Each property value specifies a
URLpointing to a login configuration file to be loaded. Read in and load each configuration. -
The
java.lang.Systemproperty java.security.auth.login.config may also be set to aURLpointing 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. - If the java.security.auth.login.config property is defined using "==" (rather than "="), then ignore all other specified login configurations and only load this configuration.
- If no system or security properties were set, try to read from the file, ${user.home}/.java.login.config, where ${user.home} is the value represented by the "user.home" System property.
The configuration syntax supported by this implementation is exactly that syntax specified in the
javax.security.auth.login.Configurationclass.- See Also:
