Hostname escaping characters. Bug in ExternalComponent connection?

Hi all

I am trying to develop a simple external component but I got stuck with what I suppose is a connection problem. I have a code looking like this:

publicclass Main {    publicstaticvoid main(String[] args)    {        ExternalComponentManager mgr = new ExternalComponentManager("myHost-ubuntu", 5276);        mgr.setSecretKey("mysub", "123456");          try        {            mgr.addComponent("simpleservice", new ServiceComponent());        }        catch (ComponentException e)        {            Logger.getLogger(Main.class.getName()).log(Level.SEVERE, "main", e);            System.exit(-1);        }          while (true) {            try{                Thread.sleep(10000);            }catch (Exception e) {                Logger.getLogger(Main.class.getName()).log(Level.SEVERE, "main", e);            }        }    }}

And I receive an error:

SEVERE: main

I suppose that the problem is with my host name as connection might not escape the '-' in my hostname. How can I change a hostname? Or maybe the problem is somewhere else? I tried to manually change my computer hostname by running in terminal "hosname newHostname" command and then restart setup for openfire server but that would not do the trick.

I don't care if I could loose any data right now as I have nothing relevant connected to the server.
