JRE 8 rt.jar - com.* Package Source Code

JRE 8 rt.jar is the JAR file for JRE 8 RT (Runtime) libraries. JRE (Java Runtime) 8 is the runtime environment included in JDK 8. JRE 8 rt.jar libraries are divided into 6 packages:

com.* - Internal Oracle and Sun Microsystems libraries
java.* - Standard Java API libraries.
javax.* - Extended Java API libraries.
jdk.* -  JDK supporting libraries.
org.* - Third party libraries.
sun.* - Old libraries developed by Sun Microsystems.

/**
 * Class TransientNameServer is a standalone application which
 * implements a transient name service. It uses the TransientNameService
 * class for the name service implementation, and the BootstrapServer
 * for implementing bootstrapping, i.e., to get the initial NamingContext.
 * <p>
 * The BootstrapServer uses a Properties object specify the initial service
 * object references supported; such as Properties object is created containing
 * only a "NameService" entry together with the stringified object reference
 * for the initial NamingContext. The BootstrapServer's listening port
 * is set by first checking the supplied arguments to the name server
 * (-ORBInitialPort), and if not set, defaults to the standard port number.
 * The BootstrapServer is created supplying the Properties object, using no
 * external File object for storage, and the derived initial port number.
