      • getInvocableMethod

        public java.lang.reflect.Method getInvocableMethod​(java.lang.reflect.Method method)
        Description copied from class: ComponentProvider
        Get the method which should be invoked instead provided one.

        Useful mainly for EJB container support, where methods from endpoint class cannot be invoked directly - Tyrus needs to use method declared on remote interface.

        Default implementation returns method provided as parameter.

        Overrides:
        getInvocableMethod in class ComponentProvider
        Parameters:
        method - method from endpoint class.
        Returns:
        method which should be invoked.
