Example 2 with ServerNotActiveException

the class Transport method serviceCall.

/**
     * Service an incoming remote call. When a message arrives on the
     * connection indicating the beginning of a remote call, the
     * threads are required to call the <I>serviceCall</I> method of
     * their transport.  The default implementation of this method
     * locates and calls the dispatcher object.  Ordinarily a
     * transport implementation will not need to override this method.
     * At the entry to <I>tr.serviceCall(conn)</I>, the connection's
     * input stream is positioned at the start of the incoming
     * message.  The <I>serviceCall</I> method processes the incoming
     * remote invocation and sends the result on the connection's
     * output stream.  If it returns "true", then the remote
     * invocation was processed without error and the transport can
     * cache the connection.  If it returns "false", a protocol error
     * occurred during the call, and the transport should destroy the
     * connection.
