## Class RemoteServer

- java.lang.Object
- - java.rmi.server.RemoteObject
  - - java.rmi.server.RemoteServer

- All Implemented Interfaces:
    Serializable, Remote
  Direct Known Subclasses:
    Activatable, UnicastRemoteObject

      public abstract class RemoteServer
      extends RemoteObject

  The `RemoteServer` class is the common superclass to server implementations and provides the framework to support a wide range of remote reference semantics. Specifically, the functions needed to create and export remote objects (i.e. to make them remotely available) are provided abstractly by `RemoteServer` and concretely by its subclass(es).

    JDK1.1

- - ### Constructor Detail

    - #### RemoteServer

          protected RemoteServer()

      Constructs a `RemoteServer`.
      Since:
        JDK1.1

    - #### RemoteServer

          protected RemoteServer(RemoteRef ref)

      Constructs a `RemoteServer` with the given reference type.
      Parameters:
        `ref` - the remote reference
      Since:
        JDK1.1

  - ### Method Detail

    - #### getClientHost

          public static String getClientHost()
                                      throws ServerNotActiveException

      Returns a string representation of the client host for the remote method invocation being processed in the current thread.
      Returns:
        a string representation of the client host
      Throws:
        `ServerNotActiveException` - if no remote method invocation is being processed in the current thread
      Since:
        JDK1.1

    - #### setLog

          public static void setLog(OutputStream out)

      Log RMI calls to the output stream `out`. If `out` is `null`, call logging is turned off.

      If there is a security manager, its `checkPermission` method will be invoked with a `java.util.logging.LoggingPermission("control")` permission; this could result in a `SecurityException`.

      Parameters:
        `out` - the output stream to which RMI calls should be logged
      Throws:
        `SecurityException` - if there is a security manager and the invocation of its `checkPermission` method fails
      Since:
        JDK1.1
      See Also:
        `getLog()`

    - #### getLog

          public static PrintStream getLog()

      Returns stream for the RMI call log.
      Returns:
        the call log
      Since:
        JDK1.1
      See Also:
        `setLog(java.io.OutputStream)`
