Access deployment server informations

Hello,

I'm desperate trying to acces to the server list and configuration accessible in the configuration / deployment window.
I tryed :

ArrayList result = new ArrayList<RunnerAndConfigurationSettings>();
for (RemoteServer<?> server : RemoteServersManagerImpl.getInstance().getServers()) {
    result.add(server);
}

But I got an empty list, also I tried to instanciate the DeploymentConfigurator out of a tree view...no results also.
Please can you help me finding the correct object to get singleton, it will be so gracefull!
Thank you very much in advance.
