Examples of org.jdesktop.wonderland.runner.RunManager

org.jdesktop.wonderland.runner.RunManager
Singleton manager for starting and stopping services.
When a new runner is added to the manager, the manager will attempt to deploy the correct environment to the runner. This consists of calling the runner's deploy() method with a set of libraries. The libraries are determined by reading a configuration file, in this case located in the RunManager's jar file, in the META-INF/deploy directory. The manager will attempt to deploy all files listed in a file with the fully-qualified classname of the runner. So if the Runner is of class org.jdesktop.wonderland.sample.SampleRunner, the file META-INF/deploy/org.jdesktop.wonderland.sample.SampleRunner will be expected to contain the list of zip files to deploy. The list of files is formatted one per line, with each line containing the path to a zip file in the manager's jar file. @author jkaplan
