23 /* We follow the design of socket factories in jsse (package javax.net and javax.net.ssl).
24  * Because this package don't the JDK yet, and not exported in Europe, we don't extend its classes.
25  * But we remain compatible, and could actualy use the jsse instead.
26  *
27  * The basic idea is to setup policies related to the sockets being constructed,
28  * in the factory: no special configuration is done in the code which asks for the sockets.
29  *
30  * We will use the polymorphism of both factories and sockets, to enable poeple
31  * to use different SSL implementations. The ORB will get different kinds of factories.
32  * The Factories will customize the special parameters used in socket construction.
33  * But the sockets returned to the application have to be subclasses of java.net.Socket,
34  * Which factory classes is used will be decide in org.jacorb.util.Environment as this is specific
35  * to the environment configuration.
36  * So the getDefault method could return null if no SSL support at all, or a factory that encapsulates
37  * a particular implementation and take care of initialising and pass specific parameters.
