RE: How to bind and work with OpenStack extensions
Hi again!
I am not aware of a guide on how to make a new nova extension, but I will look
around. We have a number of extensions which you could use as examples to
develop your own extension. If you have questions about implementing it, you
can also ask them in the #jclouds channel on IRC (a bit faster for less complex
questions). I will let you know if I find some more information about
implementing new extensions.

You said "It seems to me you might be using getExtensionApiForZone to get a
list of the extensions and then use one of these extensions?"
Yes, you got it right. I use this to get one of the extension that I want that
is implemented by a provider.
The extension gives an 'alias' which is typically then use construct a URL and
then create a domain class to represent that extension.
My original question is :
" Does JCloud have any helper classes to allow me to create one of these
domain API classes or do I have to wrap my own?".
Specifically, if I am a vendor and I want to write a vendor-specific extension
JCloud domain API class(for example, SecurityGroupApi) surely JCloud must have
a prescribed way to allow a vendor to write such a a domain API object
associated with that extension so that everyone conforms to the same pattern.

Thanks. Those examples shows the specific nova extensions that OpenStack
happened to support.
What if an openstack implementation have an specific extension and how do I
bind to it and use it?.
For example, in nova we have:
ExtensionApi extApi=novaApi.getExtensionApiForZone("");
Set exts=extApi.list();
Extension ext1=;
String alias1=ext1.getAlias();
Q: How do I construct an extension domain class from that "alias1"?.
Is there any helper classes or boilerplate code that one could use?.
I just want to make sure that I don't reinvent the wheel.

Subject: How to bind and work with OpenStack extensions
Hi:
Assuming that I have an OpenStack extension, for say,
ServerAPI, my question is do JCloud have some standard classes/utilities way
to allow me to bind to it and start using it or do I have to write my own JSON
calls??.
Sample code would be nice :)
Thanks,
BK

RE: How to bind and work with OpenStack extensions
Do you mean already implemented extensions, such as the security group
extension? I have an example for it here:
https://gist.github.com/zack-shoylev/6517903
Or do you need to implement your own extension?
It seems to me you might be using getExtensionApiForZone to get a list of the

RE: How to bind and work with OpenStack extensions
The openstack server api is called nova. You can use nova to talk to an openstack nova service.
