Until now, we use:

• null for serveur root

  new org.ametys.servercomm.ServerMessage(null, "path/relative/to/root", ...)
  

• pluginName for a URL relative to plugin

  new org.ametys.servercomm.ServerMessage("pluginName", "path/relative/to/plugin", ...)
  

Now :

• null should be the current workspace
• _workspaceName should a url relative to the workspace
• pluginName is still a url relative to the plugin
