* One specifies a class which implements this interface via the

* * Example:
*
* -Dcom.sun.CORBA.connection.ORBSocketFactoryClass=MySocketFactory *
* * Typically one would use the same socket factory class on both the * server side and the client side (but this is not required).
*
* A ORBSocketFactory class should have a public default
* constructor which is called once per instantiating ORB.init call.
* That ORB then calls the methods of that ORBSocketFactory
* to obtain client and server sockets.
*
* This interface also supports multiple server end points. See the

/**
* DEPRECATED. DEPRECATED. DEPRECATED. DEPRECATED. * * This method is used by a server side ORB.
*
* When an ORB needs to create a listen socket on which connection
* requests are accepted it calls
*
* createServerSocket(String type, int port).
*
* The type argument says which type of socket should be created.
*
* The interpretation of the type argument is the responsibility of
* an instance of ORBSocketFactory, except in the case
* of IIOP_CLEAR_TEXT, in which case a standard server
* socket should be created.
* * * Multiple Server Port API:
* * In addition to the IIOP_CLEAR_TEXT listening port, it is possible * to specify that an ORB listen on additional port of specific types.
* * This API allows one to specify that an ORB should create an X, * or an X and a Y listen socket.
* * If X, to the user, means SSL, then one just plugs in an SSL * socket factory.
*
* Or, another example, if X and Y, to the user, means SSL without
* authentication and SSL with authentication respectively, then they
* plug in a factory which will either create an X or a Y socket
* depending on the type given to
*
* createServerSocket(String type, int port).
*
* One specifies multiple listening ports (in addition to the
* default IIOP_CLEAR_TEXT port) using the
*
* ORBConstants.LISTEN_SOCKET_PROPERTY
*
* property.
* * Example usage:
* *
* ... \
* -Dcom.sun.CORBA.connection.ORBSocketFactoryClass=com.my.MySockFact \
* -Dcom.sun.CORBA.connection.ORBListenSocket=SSL:0,foo:1 \
* ...
*
*
* The meaning of the "type" (SSL and foo above) is controlled
* by the user. * * ORBListenSocket is only meaningful for servers.
* * The property value is interpreted as follows. For each * type/number pair:
* * If number is 0 then use an emphemeral port for the listener of * the associated type.
* * If number is greater then 0 use that port number.
*
* An ORB creates a listener socket for each type
* specified by the user by calling
*
* createServerSocket(String type, int port)
*
* with the type specified by the user.
* * After an ORB is initialized and the RootPOA has been resolved, * it is then listening on * all the end points which were specified. It may be necessary * to add this additional end point information to object references * exported by this ORB.
*
* Each object reference will contain the ORB's default IIOP_CLEAR_TEXT
* end point in its IOP profile. To add additional end point information
* (i.e., an SSL port) to an IOR (i.e., an object reference) one needs
* to intercept IOR creation using
* an PortableInterceptor::IORInterceptor.
* * Using PortableInterceptors (with a non-standard extension):
*
* Register an IORInterceptor. Inside its
* establish_components operation:
*
*
*
* com.sun.corba.se.spi.legacy.interceptor.IORInfoExt ext;
* ext = (com.sun.corba.se.spi.legacy.interceptor.IORInfoExt)info;
*
* int port = ext.getServerPort("myType");
*
*
*
* Once you have the port you may add information to references
* created by the associated adapter by calling
*
* IORInfo::add_ior_component
*
*
* Note: if one is using a POA and the lifespan policy of that
* POA is persistent then the port number returned
* by getServerPort may
* be the corresponding ORBD port, depending on whether the POA/ORBD
* protocol is the present port exchange or if, in the future,
* the protocol is based on object reference template exchange.
* In either
* case, the port returned will be correct for the protocol.
* (In more detail, if the port exchange protocol is used then
* getServerPort will return the ORBD's port since the port
* exchange happens before, at ORB initialization.
* If object reference
* exchange is used then the server's transient port will be returned
* since the templates are exchanged after adding components.)
* * * Persistent object reference support:
* * When creating persistent object references with alternate * type/port info, ones needs to configure the ORBD to also support * this alternate info. This is done as follows:
* * - Give the ORBD the same socket factory you gave to the client * and server.
* * - specify ORBListenSocket ports of the same types that your * servers support. You should probably specify explicit port * numbers for ORBD if you embed these numbers inside IORs.
* * Note: when using the port exchange protocol * the ORBD and servers will exchange port * numbers for each given type so they know about each other. * When using object reference template exchange the server's * transient ports are contained in the template.
*
*
* - specify your BadServerIdHandler (discussed below)
* using the
*
* ORBConstants.BAD_SERVER_ID_HANDLER_CLASS_PROPERTY
* * Example:
* *
*
* -Dcom.sun.CORBA.POA.ORBBadServerIdHandlerClass=corba.socketPersistent.MyBadServerIdHandler
*
*
*
* The BadServerIdHandler ...
*
* See com.sun.corba.se.impl.activation.ServerManagerImpl.handle
* for example code on writing a bad server id handler. NOTE: This
* is an unsupported internal API. It will not exist in future releases.
*
* * * Secure connections to other services:
*
* If one wants secure connections to other services such as
* Naming then one should configure them with the same
*
* SOCKET_FACTORY_CLASS_PROPERTY and
* LISTEN_SOCKET_PROPERTY
*
* as used by other clients and servers in your distributed system.
