Re: JClouds and OpenStack : uses or overrides a deprecated API

[Everett Toews]

Have a look at how the Context is built in the OpenStack Getting Started Guide

http://jclouds.apache.org/guides/openstack/

That will steer you clear of those deprecations.

Thanks,
Everett

Hello,
I'm trying to list images available on OpenStack using Jclouds (Version 1.8.1).
When i run the command :

javac -classpath ".:lib/*" JCloudsOpenStack.java to compile the java File, i 
got the following error :
JCloudsOpenStack.java:23: error: cannot find symbol
  private RestContext<NovaApi, NovaAsyncApi> nova;
                                                ^
    symbol:  class NovaAsyncApi
    location: class JCloudsOpenStack
Note: JCloudsOpenStack.java uses or overrides a deprecated API.
Note: Recompile with -Xlint:deprecation for details.
1 error
Any idea to resolve this problem please...
