5.9 The RMIFailureHandler Interface

The java.rmi.server.RMIFailureHandler interface provides a method for specifying how the RMI runtime should respond when server socket creation fails (except during object export).

package java.rmi.server;

public interface RMIFailureHandler {

	public boolean failure(Exception ex);
}

The failure method is invoked with the exception that prevented the RMI runtime from creating a java.net.ServerSocket. The method returns true if the runtime should attempt to retry and false otherwise.

Before this method can be invoked, a failure handler needs to be registered via the RMISocketFactory.setFailureHandler call. If the failure handler is not set, the RMI runtime attempts to re-create the ServerSocket after waiting for a short period of time.

Note that the RMIFailureHandler is not called when ServerSocket creation fails upon initial export of the object. The RMIFailureHandler will be called when a ServerSocket creation after a failed accept on that ServerSocket.
