Re: [Simple-support] How to parse xml into objects I can use to build a richfaces tree?

[Niall G. <gal...@ya...>]

Hi,

This should work for your XML.

@Root
class DeviceCollection{
  
   @ElementList(inline=true)
   private Collection<Device> list;

   @Root
   private static class Device {
      @Element String deviceId;
      @Element String name;
   } 

   public Collection<Device> getDeviceCollection() {
      return list;
   } 
}
