      Wrap the given arbitrary exception that happened during remote access in either a RemoteException or a Spring RemoteAccessException (if the method signature does not support RemoteException).
      static java.lang.Object invokeRemoteMethod(MethodInvocation invocation, java.lang.Object stub)
      Perform a raw method invocation on the given RMI stub, letting reflection exceptions through as-is.

        Perform a raw method invocation on the given RMI stub, letting reflection exceptions through as-is.
        Parameters:
        invocation - the AOP MethodInvocation
        stub - the RMI stub
        Returns:
        the invocation result, if any
        Throws:
        java.lang.reflect.InvocationTargetException - if thrown by reflection

      • convertRmiAccessException

        public static java.lang.Exception convertRmiAccessException(java.lang.reflect.Method method,
                                                            java.lang.Throwable ex,
                                                            java.lang.String message)
        Wrap the given arbitrary exception that happened during remote access in either a RemoteException or a Spring RemoteAccessException (if the method signature does not support RemoteException).

        Only call this for remote access exceptions, not for exceptions thrown by the target service itself!

        Parameters:
        method - the invoked method
        ex - the exception that happened, to be used as cause for the RemoteAccessException or RemoteException
        message - the message for the RemoteAccessException respectively RemoteException
        Returns:
        the exception to be thrown to the caller

        Convert the given RemoteException that happened during remote access to Spring's RemoteAccessException if the method signature does not support RemoteException. Else, return the original RemoteException.
        Parameters:
        method - the invoked method
        ex - the RemoteException that happened
        serviceName - the name of the service (for debugging purposes)
        Returns:
        the exception to be thrown to the caller

        Convert the given RemoteException that happened during remote access to Spring's RemoteAccessException if the method signature does not support RemoteException. Else, return the original RemoteException.
        Parameters:
        method - the invoked method
        ex - the RemoteException that happened
        isConnectFailure - whether the given exception should be considered a connect failure
        serviceName - the name of the service (for debugging purposes)
        Returns:
        the exception to be thrown to the caller

      • isConnectFailure

        public static boolean isConnectFailure(java.rmi.RemoteException ex)
        Determine whether the given RMI exception indicates a connect failure.

        Treats RMI's ConnectException, ConnectIOException, UnknownHostException, NoSuchObjectException and StubNotFoundException as connect failure.

        Parameters:
        ex - the RMI exception to check
        Returns:
        whether the exception should be treated as connect failure
