[vbox-dev] Exception calling IMachine.getName() through java webservice API

[Gerry Egan]

Hello.

I am trying to get the names and OS types of virtual machines using the Java
webservice API. I am able to get the names but I get an exception every time
and I cannot find the cause of this. The code I am running is:

public void getVmNames()
    {
        mgr = new IWebsessionManager("http://localhost:18083/");
        vbox = mgr.logon("test", "test");
        try
        {
            List<IMachine> machines=vbox.getMachines();
            for (IMachine m : machines)
            {
                vmListModel.addElement(m.getName()+" "+m.getOSTypeId());
            }
        }
        catch (Exception e)
        {
            e.printStackTrace();
        }
        cleanup();
     }

The printout from the exception is:

        ... 29 more

A similar piece of code can be found in the clienttest.java example, when I
run the clienttest show vms code I get the same exception.
I am using VirtualBox 3.6 and the host is Windows server 2003. Any help
would be greatly appreciated!
