Subject Re: Fwd: Need Help to resolve Custom Retry Handler Issue
Date Tue, 13 Sep 2016 18:49:37 GMT
Hi,

It is not easy to override bindings in Guice modules. The common way to do
that is by using the "Modules.override" helper but in this case, since the
module that defines the binding is a default module in the api metadata and
it is jclouds who instantiates it, you won't be able to use that.

What you can do is a linked binding from the default implementation to your
custom one. Something like:

bind(RetryOnRenew.class).to(YourImpl.class);

(If I'm not wrong this is the handler that is already registered)
Your impl will have to extend the jclouds default one, apply your logic
and/or fallback to the superclass.

HTH!

I.
